We know that exercise has positive effects on the brain. Researchers at Duke University demonstrated several years ago that exercise has antidepressant properties. Other studies have shown that exercise can improve brain function in older people and may even protect against dementia. How exercise improves mental health?
A theory of some of the benefits of exercise is the fact that the exercise triggers the production of endorphins. These natural opiates are chemically similar to morphine. They can be produced as a natural painkiller in response to the shock, the body receives during the year. However, researchers are wondering whether endorphins improve mood. Studies show that the body's metabolism of endorphins is complex, and there are additional mechanisms in the impact on mental health for the year involved.
Some studies have shown that exercise increases activity in the frontal lobes of the brain and hippocampus shown. It is not known exactly how and why this happens. Animal studies have demonstrated that increased movement of the values of serotonin, dopamine and noradrenaline. These neurotransmitters have been associated with mood elevation, and it is believed that antidepressants work by promoting these chemicals.
Movement was also found to a level of "brain-derived neurotrophic factor" (BDNF) to increase. This substance is believed to improve mood, and can the positive effects of exercise play a role. The primary role of BDNF seems to help brain cells survive longer, so it can also explain some of the positive effects of exercise on dementia.
The conclusion is that most of us feel good after exercise. Exercise is good for our mental health and our brain. One day we will understand everything better - but we can start training today.
