Some other benefits of walking are as follows

Some other benefits of walking are as follows:

• It improves circulation, as the muscles of the biggest reservoir of blood, the calf muscles, gets regularly contracted and relaxed to send the blood towards the heart and back to other organs of body. This results in better oxygenation of the blood. The improvement in oxygenation also occurs as one breathes more frequently during walking specially during brisk walking. That is why walking in a pollution free environment is recommended. 
• Because of better circulation during walking, one might also feel improvement in his urination. This is also helped by brisk breathing during which more water vapour is lost from the body and the person feels more thirsty. Better urination also helps in elimination of nitrogenous wastes from the body. Not only urination, but perspiration also eliminates waste products from the body.
• The regular movements of body including the contraction of muscles of abdominal wall improves the movement of food in the intestines (peristalsis). this facilitates elimination of stools (defecation).
