Its a common problem in old age that we tend to forget different things. Amnesia, as its commonly called for forgetting things can be physiological(normal) or pathological(abnormal). Human cells are mortal, so are neurons. As we age, several unwanted chemicals tend to accumulate in our brain causing loss of neurons, or loss of connectivity between neurons. This is responsible for the memory loss and other cognitive problems that arises with old age
Many research have been done to halt the loss of neurons in old age.Several cognitive enhancers are available in the markets which boast their effectiveness. While the research for the drugs to cure this cognitive decline is being carried, several conventional methods are also being tried. Exercise being one of them.
There are many different results of exercise and brain research coming recently. The common result of all these research is that exercise definitely helps in maintaining your brain health. Exercise releases various growth factors from our body that are necessary for neuronal growth and development. Also it increases the blood flow to the brain, causing more transport of these growth factors to the brain for the neuronal development.
There are many studies studying different type of exercise and their effect in different aspect of brain functions. I want to suggest that don´t run after the discussions. As for me,every type of exercise is beneficial for brain, be it aerobic, anaerobic or strength training. So don´t shy away from exercise. But most studies have shown aerobic exercise in the form of walking and swimming to be more beneficial for brain. For those who exercise for the brain, walking is a better exercise than swimming. The contact between your leg and the ground while walking helps in release of a specific growth factor called VEGF that is one of the main player in maintaining the brain health.
And doing exercise in a natural environment rather than inside the sports hall is important for your brain. So jogging for some 30 minutes around your home daily might be helpful in maintaining your brain health and preventing the cognitive decline.
Go for it guys and all the best.
