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 maintaining a healthy weight. Even literate, well-educated people sometimes have misguided views about what makes or keeps them healthy, often believing that regular daily exercise, regular bowel movements, or a specific dietary regime will alone suffice to preserve their good health. Despite the ever-changing, ever-conflicting opinions of the medical experts as to what is good for us, one aspect of what we eat and drink has remained constantly agreed by all: a balanced diet.
A balanced diet comprises a mixture of the main varieties of nutriments (protein, carbohydrates, fats, minerals, and vitamins). Proper nutrition is just as, if not more, important to health as exercise. If you’re concerned about being overweight, you don’t need to add the extra stress of “dieting”. No “low-fat this” or “low-carb that”; just healthful eating of smaller portions, with weight loss being a satisfying side effect. Improve health by eating real food in moderation. (For many reasons, not everyone has easy access to or incentives to eat a balanced diet. Nevertheless, those who eat a well-balanced diet are healthier than those who do not.)
Physical exercise is considered important for maintaining physical fitness and overall health (including healthy weight), building and maintaining healthy bones, muscles and joints, promoting physiological well-being, reducing surgical risks, and strengthening the immune system. Aerobic exercises, such as walking, running and swimming, focus on increasing cardiovascular endurance and muscle density. Anaerobic exercises, such as weight training or sprinting, increase muscle mass and strength. Proper rest and recovery are also as important to health as exercise, otherwise the body exists in a permanently injured state and will not improve or adapt adequately to the exercise. The above two factors can be compromised by psychological compulsions (eating disorders, such as exercise bulimia, anorexia, and other bulimias), misinformation, a lack of organisation, or a lack of motivation.
Ask your doctor or physical therapist what exercises are best for you. Your doctor and/or physical therapist can recommend specific types of exercise, depending on your particular situation. You can use exercises to keep strong and limber, improve cardiovascular fitness, extend your joints’ range of motion, and reduce your weight. You should never be too busy to exercise. There’s always a way to squeeze in a little exercise, no matter where you are. Eliminate one or maybe even two items from your busy schedule to free up time to fit in some exercise and some “YOU” time. Finding an exercise partner is a common workout strategy.
You may have heard about the benefits of diet and exercise ad nauseam, but may be unaware of the effect that your emotions can have on your physical well-being and, indeed, your longevity. Like physical health, mental health is important at every stage of life. Mental health is how we think, feel, and act in order to face life’s situations. Prolonged psychological stress may have a negative impact on health, such as weakening the immune system.
