Improve your memory 



By exercising, is walking on the beach or lifting weights at the gym, you're doing more than strengthen muscles:

 is stimulating regions of the brain and central nervous system that control every bit of movement.

 In addition, several chemical compounds, including the growth (in English, GH) are stimulated.

 The same doctors that some "anti-aging" give patients, despite being illegal to use it to those ends. 

Among the rejuvenating benefits, GH activates a biochemical and hormonal cascade that releases the brain-derived neurotrophic factor (in English, BDNF), a hormone that helps the brain to create new synapses, or connections between neurons.

 A study of 59 healthy but sedentary people between 60 and 79 years found that doing aerobic exercise for six months (and we're not talking about training for a marathon) increased their brain volume, improvement did not happen in the group were not exercising.

 Probably why many studies find that regular physical activity reduces mental decline in people with Alzheimer's disease and other dementias.

 It is for this reason also that the higher the circulating levels of BDNF in brain, the greater the ability to learn and remember.

 The lower levels, less information will be stored.

 BDNF Another benefit is that high levels of this factor control appetite and reduce the risk of obesity.

 It also stimulates the release of neurotransmitters in the brain, like serotonin and dopamine, which control mood and play an important role in depression. 

Scientists suspect that the increase in BDNF produced by exercise may partially explain the benefits of physical activity for people with depression.

 It does not take much effort to make their level of BDNF climb.

 For rats, a week of exercises in a wheel is enough. 

For humans, a single bout of high intensity exercise brings results.

 It is clear that the increase is short-term, which makes it even more important regular physical activity.
