Health is our destiny, don't you?

Health is generally defined as being "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity". This definition is used by the World Health Organization (WHO) since 1948.

Physical health

Physical fitness refers to good body health, and is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery.

A strong indicator of the health of localized population is their height or weight, which generally increases with improved nutrition and health care. This is also influenced by the standard of living and quality of life. Genetics also plays a major role in people's height. The study of human growth, its regulators, and implications is known as Auxology.

Mental health

Mental health describes either a level of cognitive or emotional well-being or an absence of a mental disorder. The World Health Organization defines mental health as "a state of well-being in which the individual realizes his or her own abilities, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to his or her community”.[3] However, despite official definitions, the term mental health, and the question of whether or not an individual is 'mentally well', remains a subjective assessment.

Maintaining health

Achieving health and remaining healthy is an ongoing process. Effective strategies for staying healthy and improving one's health include the following elements:

Nutrition

Personal health depends partially on the social structure of one's life. The maintenance of strong social relationships is linked to good health conditions, longevity, productivity, and a positive attitude. This is due to the fact that positive social interaction as viewed by the participant increases many chemical levels in the brain which are linked to personality and intelligence traits.

Sports nutrition

Sports nutrition focuses the link between dietary supplements and athletic performance. One goal of sports nutrition is to maintain glycogen levels and prevent glycogen depletion. Another is to optimize energy levels and muscle tone. An athlete's strategy for winning an event may include a schedule for the entire season of what to eat, when to eat it, and in what precise quantities (before, during, after, and between workouts and events).

Hygiene

Hygiene is the practice of keeping the body clean to prevent infection and illness, and the avoidance of contact with infectious agents. Hygiene practices include bathing, brushing and flossing teeth, washing hands especially before eating, washing food before it is eaten, cleaning food preparation utensils and surfaces before and after preparing meals, and many others. This may help prevent infection and illness. By cleaning the body, dead skin cells are washed away with the germs, reducing their chance of entering the body.

Stress management

Prolonged psychological stress may negatively impact health, such as by weakening the immune system and mind. Stress management is the application of methods to either reduce stress or increase tolerance to stress. Relaxation techniques are physical methods used to relieve stress. Psychological methods include cognitive therapy, meditation, and positive thinking which work by reducing response to stress. Improving relevant skills and abilities builds confidence, which also reduces the stress reaction to situations where those skills are applicable.

Reducing uncertainty, by increasing knowledge and experience related to stress-causing situations, has the same effect. Learning to cope with problems better, such as improving problem solving and time management skills, may also reduce stressful reaction to problems. Repeatedly facing an object of one's fears may also desensitize the fight-or-flight response with respect to that stimulus—e.g., facing bullies may reduce fear of bullies.

Prolonged hours of surfing on the Internet is a major concern that can affect the eyes significantly.[citation needed] White backgrounds on computer screens with a viewing distance of less than 14 inches is known to increase strain, mental fatigue and temporary di-chromatic visions in a normal healthy human being. Trying to opt for black or any non-white backgrounds can help in reducing eye strain in front of PCs
