The concept of health is debated since humanity cares - so, probably forever.
The World Health Organization gives a definition that has not changed since 1946:
"Health is a State of complete physical, mental and social well-being, and is not onlythe absence of disease or infirmity."
It's more a goal than a State, and this for several reasons. Firstly because the condition varies one moment (of age) to another in the same person on the basis of its activity, its power, hours of sleep that it offers or refuses, its environment, etc.
Then because the human body is not static: it always changes. From conception to adulthood, the bodies grow almost continuously (considered as well as the development of the brain is constantly around the age of 25). Past adulthood, the body continues to change as it stimulates or leave the lounge; and of course it ages under the combined effect of physical activity, the environment, diet, normal events (pregnancy, lactation) or accidental life.
However, we can say if someone is, or is not, "in good health". And it's relatively simple.
In developed countries, people who are born without disabilities and chronic disease are mostly in good health because they are properly fed and receive basic vaccines that prevent the most serious childhood diseases (diphtheria, polio, measles, tetanus). When they are "sick", this is temporary - they have a cold or bronchitis and gastroenteritis, which heals spontaneously in eight days because their immune system does the job.
Despite this, some people born with a disability are in very good health. A person who is deaf or blind or even born without an arm can be otherwise in perfect health.Even when disability is very annoying and affect their social life, it will not necessarily sound on their general State of health or their psychological health.
Similarly, some people affected by chronic conditions (seasonal allergy to pollen, migraine) can be in perfect health and remain so. Allergies can disappear by changingregion (or with appropriate treatment); migraines can diminish after menopause (forwomen) or after changing working or solved family concerns (for people of both genders). People with seasonal allergies or a migraine are not in poor health. They areholders of a physical characteristic which, sometimes, is a source of painful symptoms, but which sound not on their future health.
Good but when there is nothing special, how do we know if it is in good health?
More often, only concern was his health only in two circumstances
1 ° it feels not good
2 ° it doesn't feel bad, but we would like it to last.
I don't feel good, am I sick?
Take the first circumstance. You can feel bad (or sick) occasionally (as in the cases previously mentioned respiratory or digestive infection benign).
But from a general point of view, all benign diseases heal spontaneously in one to two weeks. So, all this lasts less than eight days is, a priori, benign. (Between eight and fifteen, it is also very likely.)
Some common symptoms are painful but do not mean that one is in poor health:
The "mechanical" pain: have pain in a limb or back is not necessarily a sign of poorhealth (or disease). When this pain appears in certain positions or after certain movements, it is probably muscular and without gravity. The muscles of the body hurt when they are too busy. Pain is a warning, and not necessarily a symptom of poor health or disease. Pain occasionally (especially when it is short) is not worrying.
Digestive disorders (acceleration of bowel movements, constipation, heartburn). Brevity (again - less than eight days) is a sign of their beneficence. Beyond eight days(or if they are important to interfere with everyday life) they justify a consultation but it does make them not serious so far.
Fatigue: this is not a sign of poor health, it is a signal that the brain sends us to tellus that we do (or that we suffer) too. In other words, it does not treat the fatigue, ittreats the causes of fatigue. The first treatment of fatigue (when it is possible) it is rest and sleep. Sometimes, it is not known to stop and rest. To ask relatives to imposeon us to stop.
Lack of appetite: everyone has the right to jump
