How do we define HEALTH?
Health does not simply mean ‘absence of disease’ or ‘physical
fitness’. It could be defined as a state of complete physical, mental and
social well-being. When people are healthy, they are more efficient at
work. This increases productivity and brings economic prosperity. Health
also increases longevity of people and reduces infant and maternal
Balanced diet, personal hygiene and regular exercise are very important
to maintain good health. Yoga has been practised since time immemorial to achieve physical and mental health. Awareness about diseases and their effect on different bodily functions, vaccination (immunisation) against infectious diseases, proper disposal of wastes, control of vectors and maintenance of hygienic food and water resources are necessary for achieving good health.
For a long time, health was considered as a state of body and mind where there was a balance of certain ‘humors’. After The discovery of blood circulation by William Harvey using experimental method
and the demonstration of normal body temperature in persons with blackbile using thermometer disproved the ‘good humor’ hypothesis of health. In later years, biology stated that mind influences, through neural system and endocrine system, our immune system and that our immune system maintains our health. Hence, mind and mental state can affect our health.
