Yoga and meditation improves brain fitness at four levels. First, it helps to develop new stem cells in the hippocampus; second, it improves the optimal blood flow in the brain, which enhances the cerebral metabolism; third, it encourages nerve cells to bind to one another; and fourth, it enhances the production of BDNF which creates new neural pathways in the brain. It is observed that regular systematic mental challenge by novel stimuli increases production and inter-connectivity of neurons and nerve growth factor. It also prevents cell death and loss of connections between neurons. The brain is capable of producing new brain cells at any age. Hence considerable memory loss is not an obvious result of aging. But just as it is with muscle strength, you have to use it or lose it. Our lifestyle, health habits, and daily activities have a huge impact on the health of our brain. Independent of our age, there are several ways through which we can improve our cognitive skills, prevent memory loss, and protect our grey matter. Yoga influences the brain on numerous ways. Yoga postures releases a plethora of hormones, all of which participate in aiding and providing a nourishing environment for the growth of brain cells. Most yoga postures increases heart rate, which pumps more oxygen to the brain.
