How are environmental sanitation, physical activities, and human health-related?

A healthy environment requires the cleanliness of surroundings. For this, we should keep our home, courtyard, neighborhood, and community clean. The process of keeping our environment clean is called environmental sanitation. Environmental sanitation, sometimes, is used synonymously as environmental health. A healthy and favorable environment always helps to provide productive manpower for the nation and it helps to maintain quality of life. Sanitation is important for all, helping to maintain health and increase life-spans. Around the world, over 800 children under age five die every day from preventable diarrhea-related diseases caused by lack of access to water, sanitation, and hygiene. Physical exercise may be taken individually or in a group depending upon the types and steps of exercise.
