health | Definition & Importance

health, in humans, the extent of an individual ’ mho continuing physical, emotional, genial, and social ability to cope with his or her environment.

This definition is merely one of many that are potential. What constitutes “ good ” health in particular can vary widely. The quite delicate individual who stays “ well ” within the average environment of his or her being may succumb to a heart fire from fleshy shovel after a blizzard ; or a low-lying inhabitant may move to a fresh home plate in the mountains, where the standard atmosphere has a lower content of oxygen, and suffer from shortness of hint and anemia until his or her bolshevik rake cell count adjusts itself to the altitude. Thus, even by this definition, the creation of good health must involve some allowance for exchange in the environment .

Bad health can be defined as the presence of disease, good health as its absence—particularly the absence of continuing disease, because the person afflicted with a sudden attack of seasickness, for model, may not be thought of as having lost good health as a result of such a bad luck. actually, there is a wide variable area between health and disease. only a few examples are necessity to illustrate the point : ( 1 ) It is physiologically normal for an individual to have a high gear blood sugar content 15 to 20 minutes after eating a meal. If, however, the boodle content remains elevated two hours by and by, this discipline is abnormal and may be indicative mood of disease. ( 2 ) A “ healthy ” individual may have developed an allergy, possibly during early childhood, to a single particular meaning. If the person never again comes in contact with the antigen that causes the allergy, all other factors remaining normal, he or she will remain in that state of health. however, should the individual come in liaison with that allergen again, tied 20 or 30 years subsequently, he or she may suffer anything from a balmy allergic reaction—a simple rash—to dangerous anaphylactic shock, coma, or evening end, depending upon the circumstances. Thus it can be seen that, unlike disease, which is frequently recognizable, tangible, and rather easily defined, health is a reasonably cloudy condition and slightly difficult to define. furthermore, physical condition and health are not synonymous terms. A seven-foot-tall basketball actor may be in excellent physical circumstance ( although outside the range of normality for acme ) but may or may not be in good health—depending, for model, on whether the individual has fallen victim to an attack of influenza.

There are further problems in settling upon a definition of human health. A person may be physically strong, insubordinate to contagion, and able to cope with physical hardship and other features of his or her forcible environment and placid be considered unhealthy if his or her genial state of matter, as measured by demeanor, is deemed unsound. genial health can itself be defined variously. Some say that a person is mentally healthy if he or she is able to function reasonably well and is emotionally and behaviorally stable. Others define it as the absence of genial perturb. In the face of confusion about definitions of health, it is most utilitarian, possibly, to define health, effective or bad, in terms that can be measured and interpreted with obedience to the ability of the individual at the time of measurement to function in a normal manner, with esteem to the likelihood of at hand disease. These measurements can be found in tables of “ reference values ” printed in textbooks of clinical medicine, diagnosis, and other references of this type. When an individual is given a health examination, the examination is likely to include a series of tests. Some of these tests are more descriptive than quantitative and can indicate the presence of disease in a apparently healthy person. such tests include the electrocardiogram to detect some kinds of heart disease ; the electromyogram for chief muscleman disorders ; liver and resentment bladder function tests ; and x-ray techniques for determining disease or malfunction of internal organs. other tests give numeric results ( or results that can be assigned numeric values—such as photometric discolor determinations ) that can be interpreted by the examiner. These are physical and chemical tests, including blood, urine, and cerebrospinal-fluid analyses. The results of the tests are compared with the reference book values, and the doctor receives clues as to the health of the affected role and, if the values are abnormal, for the methods of improving the patient ’ s health. A major trouble in the interpretation of trial results is that of biological variability. Almost without exception, address values for variables are means or adjusted means of large group measurements. For these values to have significance, they must be considered as lying somewhere near the center point of a 95 percentage range—i.e., the alleged ordinary range or, with reservations, the range from normal to the upper and lower borderline limits. thus, the 2.5 percentage below the lower restrict and the 2.5 percentage above the amphetamine limit of the 95 percentage roll are considered areas of abnormality or, possibly, illness. Some areas have wide-eyed 95 percentage ranges— rake pressure, for model, may vary well throughout the day ( for example, during drill, fear, or anger ) and remain within its range of normality. other values have ranges so minute that they are called physiologic constants. An individual ’ second torso temperature, for exemplar, rarely varies ( when taken at the same anatomic locate ) by more than a degree ( from time of rising until bedtime ) without being indicative of infection or early illness.
