This document outlines the possible health benefits of walking according to Dr. Shriniwas Kashalikar. Walking can help cleanse the skin through sweating, activate the cardiovascular and respiratory systems, tone the digestive system to relieve issues like gas and constipation, relieve joint pains and arthritis as well as back aches, and provide vitamin D through sunlight exposure. It can also save on electricity and fuel costs while allowing for practices like silence, avoidance of gossip, and prevention of infection when using elevators.
