Health is defined as a state in which physical, mental and social well-being is positively balanced in a given society. In layman's terms, individuals have no limiting factors that hinder them from performing daily tasks in all aspects of their lives. Illness is anything that causes bodily or mental harm to individuals and prevents them from functioning normally. Illnesses can be caused by environmental factors such as natural disasters and temperature extremes. They can also be caused by one's behaviours such as not maintaining healthy eating habits and exercising enough, smoking, drinking excessive amounts of alcohol, using drugs, etc.
Health is the level of functional or metabolic efficiency of a living organism. Critical elements of health include proper functioning of the cardiovascular system, respiratory system, nervous system, endocrine system (glands), metabolism (automatic processes in living organisms), immune protection (the body's nonspecific defences against illness), and skin.
