My Personal Science Toolkit

My personal Science toolkit: Breath, Garmin Forerunner, Oxymeter, Mendi and JAWPEER

I am responsible for my own development, so I have a personal science toolkit. Besides the mobile with Lumosity and the Excel Sheets, I use a Garmin Watch, Oximeter, Literature, and of course JAWPEER. Mendi’s neurofeedback is a new, interesting tool. My hope is that Mendi’s device makes it easier to optimize my personal goals. I have modest goals. Strive for good health, night sleep, and a well-functioning mind. Mendi claims that their device can enhance brain performance, therefore I will try and explore it.

Breath, Heartbeat, and Deep Brain

Personal Science is about applying quantitative methods to analyze one’s personal health. New technology and knowledge like James Nestor’s bestselling book ‘Breath’ make it possible to learn to know yourself better. Internal systems in your body monitor and regulate your metabolism including breathing, heart rate, blood pressure, and neurotransmitters. Your “superficial” consciousness is not aware of these systems. The deep brain regulates them.

The Outside Brain Monitor Layer

At the core of your nervous system is the Brainstem, the Cerebellum, and the Basal Ganglia. They handle the basic functions, common to all vertebrates. Closer to the Cerebral Cortex are the more human species-specific brain parts that include our ability to communicate. In the last 50 years, communication has exploded. With the help of new communication technology, we have built a new monitoring layer outside the Cerebral Cortex – the Information Society.

Knowledge for Good Rather Than Evil

Information Society is bidirectional. It gives information to you and takes information from you. Body temperature and blood tests inform about your physical status. Surveillance cameras ensure that you follow the laws and rules. Knowledge can be used for good and evil. A dictatorship can monitor the people to frighten and suppress them. Or we can use the new information layer to enhance and liberate ourselves. In this way, a personal science toolkit can be empowering.

Empowered By a Personal Science Toolkit

Overall, globalism moves toward more liberty and individualism. It increases personal freedom and responsibility for one’s own life. Monitor yourself to maximize your knowledge and independence. This is the essence of personal science. With the option of self-monitoring comes the ability to change, optimize and become a better version of yourself. No other than you can tell what is better. Which parameters are most interesting? What are your goals? Here are some screenshots of my last goal achieved.

Screenshots from Lumosity results, likely due to JAWPEER use

If you are interested in brain-enhancing, I recommend elastic chewing gum. I use them a lot for the last two years. To monitor the progress I use the app Lumosity. Lumosity is an invaluable brain training device. The result from using CHEW PEER is interesting. Recently, I passed 800 points in Lumosity. Remember my happiness when I scored 600 not long ago. Now my results are in the 99.8 percentile and I have no plans to stop improving.

Huberman Lessons About Neuroplasticity

Stanford professor Andrew Huberman gives a neurology course at YouTube. I highly recommend the Huberman Lab. Huberman tells that neuroplasticity is necessary for efficient brain training. Neuroplasticity is the ability of the brain to reprogram, improve and adapt. The best conclusion from my own experiences is that CHEW PEER increases neuroplasticity. Therefore, I think JAWPEER should be a tool in the personal science toolkit. At least if you like to improve your brain health.

The Role of CHEW PEER in My Personal Science Toolkit

How can CHEW PEER increase neuroplasticity? Here is my theory: Some 100 million years ago the jaw was a pumping organ, almost like a second heart. It still pumps when we chew food. The belly requires a lot of blood to melt the food. If the brain doesn’t get enough blood, we can become unconscious. When we chew, the jaw pumps extra blood to the brain to prevent this. Chewing without food increases the effect even more because there is no competing belly. Additionally, the mouth wires to the central parts of the brain by five cranial nerves. When we chew the blood goes to the activated parts of the brain, which happens to be the parts that trigger neuroplasticity.

The Invention of Elastic Chewing Gum

The invention of elastic chewing gum reveals that different designs are associated with various cognitive facilities.

The invention of elastic chewing gum is a disruptive development. Chewing gum has been around for at least 8,000 years. For at least 100 years, we know that it stimulates the brain and makes us feel alert. Exactly how it works is still not clear. In the 1980s, people began to examine brains with magnetic resonance imaging. They found that chewing increases blood flow in the central parts of the brain. After that, Japanese researchers continued to investigate the effects of chewing. In 2017, a study showed that chewing affects the HPA axis that regulates stress levels. The following year, it was also possible to prove that harder chewing resistance gives a better effect. At the same time, it became fashionable in the western world to train facial muscles.

Better Results From Elastic Chewing Gum

The invention of elastic chewing gum built on a discovery that Peer Norbäck made when chewing. He trained cognitive abilities simultaneously and noticed that his performance improved when he chewed. Peer then became curious. Therefore, he began to study all the world’s research reports that had to do with chewing. Peer realized that modern people chew too little. Then he also understood why hard chewing had this unexpected effect on the brain. Peer filed the first patent application in June 2019 (pat. No. 602778), and the following month, the company JAWPEER was formed to develop the invention of elastic chewing gum.

Environmentally Friendly and Non-Toxic

When Peer began to develop the first CHEWPEER (pat. No. 605914), he put high requirements. He decided that they should be environmentally friendly, free from toxic and safe to chew on. No harmful substances must excrete even if you chew hard. The independent research institute RISE built a machine to investigate the matter. The requirement was that they should not excrete any measurable harmful substances at all. The accuracy of the measurements was 1 ppm and CHEWPEER passed the test with no remarks. Other jaw trainers on the market are not as clean. The unique thing about JAWPEER is environmental awareness and that the products both train the face and stimulate the brain.

Designed for Both Young and Old

To minimize the risks, CHEWPEER’s design is a pattern torus (pat. No. 84699). A torus has a hole in the middle that you can breathe through if you happen to put it in the throat. It is also possible to attach a safety line to the hole. The chewing product can thus be used by both young and old. These groups benefit from chewing in different ways. Jaws, facial form, and teeth develop by chewing during childhood. Dementia that affects the elderly is associated with reduced blood flow in the brain, something that chewing can counteract. Increased blood flow in the brain also means that the brain’s ventricles fill with fluid that can flush out debris at night through the newly discovered perivascular system.

Different Models of Elastic Chewing Gum

After trying the product on a set of test users, Peer realized that different people had different chewing needs. Therefore, he developed a series of models with different sizes and hardness. They also got different pattern designs. The invention of elastic chewing gum is much more environmentally friendly than traditional “plastic” chewing gums. When the new products came from the factory, Peer tested them again. Then he noticed something exciting: different designs are associated with various cognitive facilities. A new technical patent was filed in June 2020 (Patent Pending 2030192-5)

Development of the Medical Device

Research is underway to investigate whether the hardness, size, or texture causes different CHEWPEER’s to have other effects on the brain. And the development will not stop with this study. Part of the innovation is about enhancing CHEWPEER with a sensor that registers how much you chew, which force, and which teeth to use. The statistics transfer to an app that maintains the usage. At the same time, saliva in the mouth is analyzed. Saliva contains a lot of information about the user’s health. This medical technology development starts as soon as we have the financial means needed.

CHEW PEER Prevented Sore Throat

One night Peer woke up with an itching throat during the Corona Pandemic 2020. Peer did not want to get sick. To prevent coughing, Peer put CHEWPEER in a vitamin C solution and swallowed it. Then he pulled it up with the safety line. He repeated this a few times and it had an effect. He was thus able to prevent the virus from cultivating in the throat. Since then, he has used the technology to keep colds away and always managed to stop them. The ability to prevent colds is a bonus included in the product’s patent.

Help From a Knowledgeable Patent Engineer

From early development, Peer protected the innovations in every conceivable way. The team around JAWPEER includes one of Sweden’s most knowledgeable Patent Attorneys, Lars A Wern. Wern is both an intellectual inventor and legally knowledgeable in intellectual property rights. He knows how innovative inventions usually develop. It starts with an independent inventor doing empirical experiments acquiring unique knowledge – the knowledge manifest in a product that solves one or more practical problems. Unlike several public and private investors, he sees the potential in elastic chewing gum. A disruptive invention can change the chewing gum market and create new non-invasive medical products of great benefit.

CHEWPEER Increases Neuroplasticity

Preliminary studies suggest that CHEWPEER increases neuroplasticity. By neuroplasticity the brain can change and re-program itself even later in life. Without neuroplasticity, we would not be able to learn new things. If the results are confirmed, the products will be indispensable for anyone who wants to optimize their brain or change their thinking habits. Therefore, some models of CHEWPEER can facilitate studying or improve sports performance by increasing the ability to concentrate. You can use other variants to rehabilitate burnout or traffic-injured patients. Hopefully, even cure traumatized or criminal brains. The possibilities are enormous.

An Idea Whose Time Has Come

“There is nothing more powerful than an idea whose time has come.” The quote from Victor Hugo fits into JAWPEER. The product is both healthier and more environmentally friendly than traditional chewing gum. Our bodies are made for a completely different life than the modern human. We are a herd animal, made for being outdoors a lot and using our teeth as tools. Chew-friendly JAWPEER makes it easier to live as we intended to do. When the research results start to flow in, it will show that JAWPEER is helpful in dentistry, beauty care, and not least in neurological medicine. As the market grows, the patents can form the basis for a business model built on worldwide license distribution.

Can Personal Science Help Know Thyself?

Know thyself was the famous ancient Greece device at the temple of Apollo.
Know thyself

Can you know thyself through personal science? Most of us strive to know and define ourselves. JAWPEER wants to make it easier. By chewing, both the brain and the look can improve. “Know Thyself” was the famous inscription on the temple of Apollo in ancient Greece. The ancient Greeks trained, fought, danced, fasted, ate, chewed, and philosophized to get to know themselves.

The philosopher Michel Foucault believed that what we call the self is physically measurable. Body hacking, fitness, bodybuilding, yoga, meditation, martial arts, eHealth, and eSports are all strategies to get to know yourself. Because people are different, there is no one-size-fits-all method. Who we are and want to become is determined by our environment, heritage, and habits.


Our heritage is hardwired in the genes. We cannot change DNA, but we can adapt to it. Through a DNA test, we can map our properties. What is good or healthy varies between different individuals. Evolutionary medicine is based on the fact that our DNA is not adapted to the rapid changes in society. Since we are genetically Stone Age people, it is good for us to eat the paleo diet and chew a lot. What we eat is a matter of nutrition. A diet adapted to your DNA can increase your well-being, and even prolong life. But it is not enough to eat right; the environment must be good as well.


The human environment has changed enormously since the Stone Age, not only because of the greenhouse effect. Genetically, we are made to live as hunter-gatherers in flocks and sleep in the open air. Most modern people live in a city and eat fast food. According to “Iceman” Wim Hof, we can strengthen the immune system by getting out of the comfort zone and exposing the body to extreme stress such as lack of oxygen and cold. Living too comfortably is devastating in the long run.


If you want to make an everlasting change, you better change a habit. Habits are done without thinking. Psychologist William James said that 99.9 percent of our behavior is controlled by habits. Good habits make your life good and vice versa. Self-control is about embracing good habits, but most people who try to change habits fail. Habits should therefore change gradually and one step at a time. As with JAWPEER: start carefully. In this way, the body has time to adapt.

Get to know yourself

The contemporary individualist project is to explore and identify oneself. You cannot change your DNA, but you can change the environment and habits. Research shows that it is easiest to change a habit while changing your environment. If you are moving or changing jobs, you should also take the chance to create a new and better habit. Do not try to change more than one. The chance of success is much greater if you concentrate on one thing at a time. Before you change first it is good to understand how you work.

A smartwatch helps you know yourself by self-tracking

Personal science grows with self-tracking

Personal science is perhaps the fastest growing global trend. Gary Wolf TED talk is about the technology that changes our lifestyle: smartwatches, mobile apps, IoT, and cloud services monitor our physical bodies ​​around the clock, even at night. Not only if you sleep but also what kind of sleep – deep, light, or REM sleep. Mapping one’s own habits with the help of technology are called self-tracking. This means measuring how the body behaves in different situations. Today, more than every other Swede has an app to keep track of how much they exercise, eat, or sleep. Technology makes personal science much easier. All that is required is that you are systematic and curious.

The Quantified Self – know thyself with technological aid

If we want to be more efficient and rational, we need to get to know ourselves better, says Gary Wolf. He started the QS movement, a community that deals with self-knowledge. Many physical connections are general and apply to all of us: If we sleep too little, we get tired. If we overwork a muscle, we get exercise pain etc. But some connections differ because we have different bodies, blood groups, allergies or hormones. Self-knowledge is about understanding things that affect you and no one else.

Personal Science is Just Like Other Science

Personal science uses the same methods as ordinary science. It is about finding a connection between cause and effect in an experimental way. The difference is that the researcher and the object of study are one and the same person. If you want to experiment with yourself, it is advisable to research one thing at a time. Otherwise, it can be difficult to plot causes and effects. If you check what happens when you chew JAWPEER there are a lot of things to examine. What happens to the saliva flow? How do the jaw muscles react? Do you experience any difference in concentration? Stress? Mood swing? Face shape? Take one thing at a time. Try to measure the effect with an app, so you do not have to make subjective estimates.

JAWPEER is careful with the risks

For the safety of our users, JAWPEER is careful with the risks. The material is well tested and does not emit any harmful substances. To investigate what happens if someone happens to swallow the product, I have swallowed one on purpose. I must say it passed unnoticed through the digestive system. For those who still are worried about swallowing the product, we recommend using a safety line.

Explore your unknown senses

The philosopher Aristotle, who lived in ancient Greece, thought we had only five senses. You may have heard that too. But we have at least thirteen. Chewing can stimulate ten or maybe more. The mouth registers taste and smell, but also temperature, pain, proprioception, light touch, hard touch, disgust (an own sense!), Fluid, and salt balance. All these senses are united in what is called mouthfeel. JAWPEER is therefore an extraordinary experience. CHEW PEER Collection contains products of different sizes and hardness. Examine your mouthfeel and hopefully, you will find a personal favorite.

Feel free to report interesting results

If you chew JAWPEER and discover an interesting connection, you should pay extra attention. Repeat the experiment to see if it gives the same result again. Change the experiment a little and try to get a different result. Remember that the body strives for balance, so it adapts gradually. If the result remains, try to measure the result quantitatively in some way and report it to us. Technological developments make it much easier for us to get to know ourselves than it was in ancient Greece.

What Makes Chewing Gum Attractive?


Faberge egg with a CHEW PEER instead of a diamond ring.

What makes chewing gum attractive? Is JAWPEER attractive for chewing? CHEW PEER Collection is a set of Elastic Chewing Gum – a new and super pleasant experience in many ways. Find out if they are attractive to you, and which one suits you the best. You don’t know unless you have tried.

Attractive products suit different chewing preferences

Chewing preferences vary. If you chew one plastic gum slowly and think that root vegetables are hard to chew, then you will probably like a small and soft CHEW PEER. If you chew more normally or take two gums when you chew plastic gum, you will probably prefer medium. CHEW PEER Hard is for those who really like to chew and want a bigger challenge. A lot of people should have cred for product development. Wise advisors and extensive research lie behind the products. Attractive products are both safe, durable, and useful. Security comes in the first place. Therefore, RISE is engaged to check that the products do not contain harmful substances. The test protocol can be read here.

The concept is sustainable for the future

Sustainability is important, not least for the environment. Chewing gum is a disposable product that takes 20-25 years to break down. Last year, the world’s population chewed 500,000 tonnes of plastic chewing gum, much of which ends up in nature. The goal is to replace 50 plastic chewing gums with a single CHEWPEER. But chewing wears hard and there are almost no materials that meet this sustainable requirement. We are constantly developing, the current product is the latest prototype. In other words, progress is gradually continuing. There is still a way to go before we are really happy with the outcome.

Chewing has many good effects. Therefore, JAWPEER can be useful in many ways. An important effect is the increase of glucose in the central parts of the brain. It can make the user calmer, more focused, and better at problem-solving. This will now be further investigated in a study. If it gives good results, the research continues to investigate the effect of different target groups.

Different target groups are attracted

Elastic chewing gum can be useful for different purposes: oral hygiene, reducing wrinkles, alleviating stress, preventing cheek-biting, increasing concentration, improving facial shape, etc. Several different target groups might be interested. Thus, marketing JAWPEER is an experiment. After all, it is the customers who decide. Which audience is the most interested? Early adopters are invaluable in this context. You can contribute to the development of JAWPEER if you help us to test new areas of usage. Is JAWPEER something for you? Take our test and check.

CHEWPEER is a very old invention

JAWPEER is an old invention. The image reconstruction shows how it is believed that the hunter-gatherer girl looked like chewed on JAWPEE's predecessor 6,000 years ago
Image reconstruction: Tom Björklund

CHEWPEER is in fact a very old invention. To chew for the sake of chewing is nothing new. Before modern chewing gum arrived, the chewing artifacts were made of resin. Ten thousand-year-old pieces of birch resin with tooth imprints have been found in Scandinavia. The conclusion is that people invented chewing artifacts even before they invented agriculture. National Geographic (2019-12-17) tells the story of a girl who lived about 6,000 years ago. Through DNA analysis we know a lot about her. First, the girl was lactose intolerant. Secondly, that she had recently eaten duck and hazelnuts. Besides, she was probably blue-eyed and had dark hair. Her DNA is not similar to the agricultural populations who came to Europe in the Stone Age.

The girl’s appearance is reconstructed based on her DNA found in the resin. Her appearance is based on comparisons with the DNA of living people. In other words, resin has the ability to encapsulate and preserve DNA for posterity. Jurassic Park films are based on this feature. Since the girl’s DNA could be preserved, the films don’t feel completely unthinkable.

CHEWPEER does not preserve information about us

CHEWPEER is a very old invention, but the idea is improved. It isn’t sticky and it doesn’t preserve your DNA. The Stone Age girl belonged to a group of hunter-gatherers and she was not completely healthy. In this case, both viruses and bacteria from the girl’s mouth were found. All this is known because she chewed on chewing gum at the time. In conclusion, this science is both interesting and a little troubling. On the one hand, the information that scientists have extracted from the piece of birch tar is impressive. On the other hand, it can be nice to have a little privacy. Finally, we should point out that CHEWPEER is different from chewing gum. They are made to be recycled and will not be disposed of in the wild. Last but not least, they preserve your privacy. The product will not encapsulate your DNA forever.

Chewing Power Affects Reward Center – the Power of Chewing

A group of people living in the environment for which our bodies are adapted. They use their mouths not only to eat but also as tools.

Chewing power affects the brain’s reward center – The Power of Chewing is a slogan used by JAW PEER to emphasize that chewing has many good qualities. Our bodies, mouths, or by all means brains haven’t changed much in the last 50,000 years. This means that we are made to live as hunter-gatherers in the African savannah. Life as hunters and collectors was varied and more physical than we are used to. Our ancestors lived together in groups of 20-80 people and moved between different settlements. They shared the data and probably did not have to work no more than 3-4 hours a day.

The Power of Chewing helped us to survive

Instead of watching TV or surfing the web, a lot of time was spent dancing and socializing in the group. They had primitive knives and arrows, but their mouths were their most important tools. Chewing power was a big advantage. Roots, meat, and nuts were chewed to nourish. Plant fiber, tendons and animal hides were chewed to make utensils and clothing. Therefore, the masseter muscle is the strongest muscle, and enamel the hardest material in the body. When the masseter muscle works, it goes to our reward center.

Chewing power affects the reward center in the brain

Human bite strength and chewing power stand up well in relation to our closest genetic relatives to the monkeys, according to an article in National Geographic. But “The Power of Chewing” doesn’t just refer to the power of the bite. The secret is that chewing power affects the reward center – the Power of Chewing is a source of joy. As a positive spinoff effect, blood flow in the central parts of the brain increases when chewing. Those of our ancestors who liked to chew were rewarded through the selective selection of evolution, which is why the brain secretes a pleasant mix of hormones when we chew. “The Power of Chewing” means that when we chew, we become more alert and at the same time more relaxed. To stimulate our biological nature, we should use our mouth more by chewing. JAW PEER is made to help with this.

Can you get satisfied without eating?

The leptine molecule can make you satisfied without eating

Can you get satisfied without eating? Science is trying to understand how. It’s not a full stomach that makes us satiated, rather a hormone called Leptin. Leptin sends signals to the brain that the stomach is full. Previously, it was thought that leptin was only formed in adipose tissue. New research shows that it is also produced in the salivary glands and oral mucous membranes. The more power you chew with, the more saliva is formed. CHEW PEER stimulates saliva flow and increases total leptin secretion up to three times (P <0,001). source DOI: 10.1210/jcem.86.11.7998

Leptin creates feelings of satiety

The walls of the stomach contain receptors that absorb leptin. It follows the saliva into the stomach where it resorbs. This should make it possible to be satisfied without eating but by chewing and swallowing saliva. Chewing can create satiety sensations that could have biological explanations. Our ancestors who were hunter-gatherers often lived near the famine. When they ran out of food, they had to live on nutrients in roots and bone marrow. Then it was good that they could be satisfied without eating. Starving food has poor nutrients. It means that it takes time to get nutrition by hard chewing. But we can actually enjoy that even today if we have problems with weight or oral health.

One of the test users had JAWPEER to reduce their snacking and to feel saturated without eating. When the candy craving struck, a CHEW PEER entered the mouth. After a few minutes of chewing, the longing for sweets and sweets has disappeared. The product is better for both teeth and Body Mass Index than candies or sweets. If JAWPEER has this effect for multiple users, they can use CHEW PEER to control their weight. According to previous chewing studies, we can at the same time become more alert, think faster, and get better working memory. Other studies suggest that chewing makes it easier to concentrate and manage stress. There are also further studies that suggest that chewing provides better mood, impulse control, oral hygiene, and breath.

The Gateway to Our Biological System

systems theory

The mouth is the gateway to our biological system. This view comes from Systems Theory. The theory developed in the 20th century by Ludwig von Bertalanffy, Ralph Gerard, and Anatol Rapoport, among others. The development of technologies like computation and Artificial Intelligence built on it.

Biological systems are role-models for artificial systems

Humans are biological systems. The inspiration for the development of computers came from how we think and work. Therefore, technical systems like computers have certain things in common with us. System theory is based on some key concepts found in everything from mathematical functions to biological ecosystems. They may be useful to know:

  • INPUT is what the system consumes
  • GOAL is the state a system strives for
  • SYSTEM FUNCTION f(x) is to convert the input to output
  • RESOURCES is (in addition to input) what enables the system to do a job
  • OUTPUT is what the system produces

The mouth is the gateway to our biological system

If humans are biological systems, the mouth is the gateway. This is because the mouth is central to the input. That’s why the brain has a super-track of everything we put in it. The brain deals with the system goals. It receives information from the gut via the vagus nerve. This nerve passes the mouth, as four other main nerves. Otherwise, we can’t determine if our input can be eaten, drunk, or inhale. The brain has much better ability to discern it than we imagine. This is due to five cranial nerves that provide the brain with real-time information about what is happening in the mouth.

Consciousness is not fully aware of the mouth

The work of the nerves is fast and much of this activity takes place under the horizon of consciousness. An explanation is that the human consciousness is a recent evolutionary product. The mouth is much older, about half a billion years. Therefore, we do not really understand what happens when we put something new in the gateway to our system, such as a new chewing thing. Those who have tried JAW PEER experience that brain makes a kind of examination the first time. Given how complicated the brain and mouth feel are, perhaps we should be glad that consciousness lets the system take care of itself.

Control Your Stress by Chewing

Rats can cope with stress by chewing. There is much evidence that people can use the same strategy

Is it possible to control your stress by chewing? Rats can cope with stress this way. Stress impairs the nerve signals that control the ability to think, remember, and learn. Our brains can be damaged by repeated stressful situations. In the worst case, the damages become permanent. For ethical reasons, therefore, no stress studies are made on humans. Instead, poor rats are stressed in the laboratory. The rat trials may be horrible, but if we can learn from them much is gained.

Rats can control their stress by chewing

A scientific study allowed two groups of rats to be exposed to very stressful situations. One group had to chew on a piece of wood to cope with the stress, while the other group had nothing to gnaw at. They then took blood samples of the rats at different times and measured how the stress had affected the ability of brain cells to transmit signals. Within 24 hours, the nerve signals were restored for the rats chewing during the stress, while the signal transmission remained low in the group not chewing.

Relationship between stress and obesity

The study in the rats showed that chewing had a positive impact on the rat brain’s ability to cope with stress. Chewing improves recovery after stress in rats may indicate that chewing is a good strategy for dealing with severe stress even in humans. However, we should not gnaw at pieces of wood because it can cause splinters to stick in the gums. Eating a lot of food is also not good. There is a link between stress and overweight. Since rats can cope with stress by chewing, it is perhaps not so strange if humans work the same. Many stressed people also get the urge to put food and sweets in their mouths, which can cause overweight and other health problems.

Now there is finally something to bite into that does not increase the waist circumference. JAW PEER is a product designed to help people who place high demands on themselves. People who feel they are on the verge of being burnt out can chew on a CHEW PEER to cope with stress. This avoids risking damage to the brain that tough stress can lead to. But if the alarm bells ring for burnout, you should not only acquire CHEW PEER, but also acquire healthier habits.

Get Better Study Results if You Chew

Get better study results if you chew. Dont use a pencil to chew on. Use JAWPEER.

Studying and chewing works well together. It is not enough just to study hard, you also have to be able to focus on the degree assignment. It seems to be easier to focus if you chew at the same time. A scientific study showed that you increase the blood in parts of the frontal lobe when chewing. Therefore, those who chew may find it easier to focus. The brain can more easily shield things that interfere when you are concentrated. Therefore, it is smart for students to use CHEW PEER at important tests.

Chewing activates important parts of the brain

An area that is activated when chewing is called the prefrontal cortex. The area belongs to the most recently developed parts of the brain. It controls, among other things, working memory and spatial thinking. Chewing can thus improve working memory and at the same time increase concentration. Therefore, those who study have a lot to gain from chewing. From DOI: 10.1016/j.neulet.2008.03.033

Better study results if you chew

Students who chew in conjunction with tests do better according to a study. That’s why it’s good to have something to chew on when you’re studying. The study also examined whether the students experienced stress during graduation. The results showed that the students who chewed felt significantly better. In addition, they performed better in comparison. This means that chewing also seems to affect how we feel. Therefore, students are recommended to study and chew at the same time.

JAW PEER is a box with CHEW PEER and other accessories. CHEW PEER is made to chew on. There are different types of CHEW PEER; soft medium and hard. Soon they will also be available in different sizes. Accessories include a safety line and an instruction sheet. But soon there will also be oils to reduce the chewing sound. They have taste and other additives that can enhance the desirable effects of chewing. Two CHEW PEER’s are chewed with both chewing surfaces at the same time for maximum effect.

The softer and smaller variants are more suitable for relaxation and anti-stress. Bigger and harder CHEW PEER is better for jaw training and sports. The products are elastic and retain their shape and elasticity after chewing. Therefore, they are not disposable products but can be reused. All variants provide greater chewing resistance measured with Shore Durometer than regular chewing gum. Which variant you choose is a matter of taste. A starter kit with several different variants is made to try out. Then you’ll be able to subscribe to the one you like best. All variants make it easy to study and chew.
