What You'll Learn
Myokines are released during physical activity
Physical activity has been proven to improve our mood and mental health. Scientists have found that whenever we move a muscle, we produce "hope molecules". These are chemicals naturally found in the body that can be increased through physical activity, pleasurable activities, and social connection.
Hope molecules are released during physical activity in the form of proteins called myokines. These are released into the bloodstream and pass through the blood-brain barrier to change the structure of the brain and have an antidepressant effect. Myokines make us more resilient to stress and trauma. They are also directly linked to improvements in the body and brain.
Myokines are released by muscle contractions during physical activity and have an endocrine function. They are able to communicate with several key metabolic organs, such as adipose tissue, the liver, and the pancreas, to regulate energy homeostasis and organ function. Myokines can also regulate lipid mobilization from adipose tissue, liver endogenous glucose production, insulin secretion by beta pancreatic cells, and activate thermogenesis.
The secretion and action of different types of myokines depend on the type of exercise. For example, endurance training or resistance training can lead to varying results in the expression of certain myokines. Irisin, a recently identified myokine, is considered the most promising in the context of metabolism maintenance as it is secreted by skeletal muscle and mediates the effect of exercise on adipose tissue metabolism.
In addition to myokines, neurotransmitters such as dopamine and serotonin are also released during exercise and can positively impact the brain. Exercise helps regulate stress and reduce mental health symptoms by releasing these mood-boosting neurotransmitters throughout the nervous system.

Myokines are proteins that pass through the blood-brain barrier
Exercise has long been known to have a positive impact on mental health. Scientists have discovered that whenever we move a muscle, our bodies produce "hope molecules", which are chemicals that are naturally found in the body. These molecules enhance our ability to foster positivity, resilience, and mental well-being.
The term "hope molecule" refers specifically to a protein called myokine, which is released into the bloodstream during movement. Myokines are small proteins (5-20 kDa) that are produced and released by skeletal muscle cells in response to muscular contractions. They have multiple functions, including exercise-associated metabolic changes, tissue regeneration, and repair. Receptors for myokines are found on muscle, fat, liver, pancreas, bone, heart, immune, and brain cells.
Myokines are unique in their ability to pass through the blood-brain barrier, allowing them to directly influence the structure and function of the brain. This passage through the blood-brain barrier is made possible by their ability to bind to receptors on the barrier and on brain cells (neurons and glia). Once they cross this barrier, myokines can induce downstream signaling, influencing complex brain-dependent behaviours and providing an antidepressant effect.
The secretion of myokines is stimulated by physical activity, and they have been found to have neuroprotective functions. Studies have shown that exercise can lead to significant structural alterations in the brain, and even promote neurogenesis and improved synaptic transmission. Myokines also play a role in regulating energy metabolism, controlling metabolic functions, and stimulating glucose production.
In summary, myokines are proteins that pass through the blood-brain barrier, influencing the structure and function of the brain. They are produced by skeletal muscles during physical activity and have a range of beneficial effects on the body and mind, contributing to our overall well-being.

Exercise improves cognitive function, memory, and creativity
It is now a scientific fact that there is a "magic chemical connection" between mood, strength, and longevity. Scientists have found that whenever we move a muscle, we produce "hope molecules", which are chemicals naturally found in the body that improve our mental health. During movement, proteins called myokines are released into our bloodstream, passing through the blood-brain barrier to change the structure of the brain and producing an antidepressant effect. This makes us more resilient to stress and trauma.
Exercise, in whatever form and for however long, makes life feel better. It improves our mood and sleep, and reduces stress and anxiety, all of which contribute to cognitive impairment. It also directly improves memory and thinking by reducing insulin resistance, reducing inflammation, and stimulating the release of growth factors—chemicals in the brain that affect the health of brain cells, the growth of new blood vessels in the brain, and the abundance and survival of new brain cells. Studies have shown that it takes about six months to start reaping the cognitive benefits of exercise, and that moderate-intensity exercise is particularly useful.
There are many ways to improve cognitive function, memory, and creativity through exercise. Standard recommendations advise 30 minutes of moderate physical activity most days of the week, or 150 minutes a week. Household activities can count towards this, such as intense floor mopping or raking leaves, as can everyday tasks that engage the brain. Learning new skills, such as a musical instrument, a new language or taking up a new hobby, can also help to improve brain function and boost connectivity between different areas of the brain.

Physical activity reduces symptoms of mental health issues
Physical activity has been proven to have a positive impact on mental health and well-being. It is a scientifically proven fact that there is a "magic chemical connection" between movement and improved mood and longevity. This is supported by the fact that any physical activity that gets your body moving can increase the levels of "hope molecules" or myokines in your body. These molecules are released into the bloodstream during movement and pass through the blood-brain barrier, changing the structure of the brain and creating an antidepressant effect.
Exercise is an effective way to regulate stress and reduce symptoms of mental health issues such as anxiety and depression. It can also help treat these mental health conditions, with research suggesting that physical activity can be as effective as antidepressants or cognitive behavioral therapy for mild-to-moderate depression. Furthermore, exercise improves self-esteem, cognitive function, mood, and quality of life, while also reducing stress tendencies, a factor known to aggravate mental and physical diseases.
The physical benefits of exercise are also important for people with mental illness. It improves cardiovascular health and overall physical health, reducing the risk of chronic physical conditions that are more common in people with mental health issues, such as heart disease, diabetes, arthritis, and asthma. Additionally, exercise can be an outlet for frustrations, reducing skeletal muscle tension and helping individuals feel more relaxed.
The amount of exercise recommended to improve mental health is a total of 2.5 to 5 hours of moderate physical activity or 1.25 to 2.5 hours of vigorous physical activity per week. However, any exercise is better than none, and even low-intensity activities such as leisurely walks, stretching, or yoga can have significant benefits for mental health. Structured group programs and mind-body exercises such as yoga can be especially beneficial for individuals with serious mental illness.

Social connection boosts hope molecules
"Hope molecules" are biochemical substances released into the body during physical activity that positively impact our mental health. They are informally called "hope molecules" because they trigger processes that reduce stress, anxiety, and depression while promoting mental resilience and positive emotions.
While physical activity is a key factor in the release of these molecules, social connection is another integral part of human life that can boost them. Research shows that social connectedness can improve well-being and overall quality of life. It can encourage people to adopt healthier habits, such as eating healthier and engaging in regular exercise, which in turn positively impacts mental health.
For instance, exercising in a group setting, such as joining a team, a community gym, or a yoga class, can provide a sense of community and enhance social connections. This social aspect of exercise can lead to the formation of strong social bonds, which have been linked to various benefits, including a reduced risk of serious illnesses and a longer lifespan.
Additionally, endorphins released during sustained physical activity can help strengthen social bonds and build extended families and social networks, further contributing to social connection. This social connection resulting from physical activity can help stave off loneliness and social isolation, promoting a sense of belonging and enhancing overall well-being.
Therefore, while physical activity is essential, the social connections that can be formed through group exercise or shared fitness interests play a crucial role in boosting "hope molecules" and fostering a positive feedback loop for mental health and overall quality of life.
