What is Health?
How do you define health? Is it a state of complete physical, mental and social well-being? Is it merely the absence of disease or infirmity? Or is health a resource for everyday life, rather than the objective of living; a positive concept, emphasising social and personal resources as well as physical capabilities?
Good health is harder to define than bad health (which can be equated with the presence of disease), because it must convey a concept more positive than mere absence of disease, and there is a variable area between health and disease. Health is clearly a complex, multidimensional concept. Health is, ultimately, poorly defined and difficult to measure, despite impressive efforts by epidemiologists, vital statisticians, social scientists and political economists. Each individual’s health is shaped by many factors, including medical care, social circumstances, and behavioural choices.
While it is true to say that health care is the prevention, treatment and management of illness, and the preservation of mental and physical well-being, through the services offered by the medical, nursing and allied health professions, health-related behaviour is influenced by our own values, which are determined by upbringing, by example, by experience, by the company one keeps, by the persuasive power of advertising (often a force of behaviour that can harm health), and by effective health education. Healthy individuals are able to mobilise all their physical, mental, and spiritual resources to improve their chances of survival, to live happy and fulfilling lives, and to be of benefit to their dependants and society.
Achieving health, and remaining healthy, is an active process. Natural health is based on prevention, and on keeping our bodies and minds in good shape. Health lies in balancing these aspects within the body through a regimen consisting of diet, exercise, and regulation of the emotions. The last of these is too often ignored when health advice is dispensed, but can have a pronounced effect on physical well-being.
Every day, or so it seems, new research shows that some aspect of lifestyle – physical activity, diet, alcohol consumption, and so on – affects health and longevity. Physical fitness is good bodily health, and is the result of regular exercise, proper diet and nutrition, and proper rest for physical recovery. The field of nutrition also studies foods and dietary supplements that improve performance, promote health, and cure or prevent disease, such as fibrous foods to reduce the risk of colon cancer, or supplements with vitamin C to strengthen teeth and gums and to improve the immune system. When exercising, it becomes even more important to have a good diet to ensure that the body has the correct ratio of macronutrients whilst providing ample micronutrients; this is to aid the body in the recovery process following strenuous exercise.
If you’re trying to lose weight by “dieting”, don’t call it a diet, first of all – successful dieters don’t call what they do a “diet”. A healthy diet and regular physical activity are both important for …
