It covers physical exercise, cleanliness, sleep, proper rest and other related practices such as keeping away from consuming alcohol, smoking, drugs etc. Many diseases can be prevented to a great extent just by maintaining good personal hygiene.

Social hygiene

The surrounding and other public places around us is our society. An individual’s mental and physical condition is greatly influenced by a good environment. Improper, unkempt and untidy surroundings and inappropriate ways of waste disposal in public places results in an unhealthy surrounding. Such practices cause an alarming growth of rodents, pathogens and other microbes and make us unwell. Consequently, both social and personal hygiene are vital aspects.

Disease

A disease causes us discomfort or an uneasy feeling, which may or may not necessarily give a pain sensation. Although “diseases-free” and “being healthy” are terms that are often correlated, they are completely different. Certain signs and symptoms are used to diagnose a particular disease.
