Health

I'm not a doctor so I strongly recommend you seek competent medical advice before you undertake any changes that might affect your health! This page is mostly for me, as a reminder to do the right thing, as not only have I had my own cancer scare but I've struggled with weight control, almost a dozen broken bones and fractures, and every type of scrape, cut, puncture wound, burn, rash, fungus, wart, cold, flu, and intestinal disorder imaginable. Plus, I was 55 years old when I started this particular page so geriatrics* (health care for the elderly) is becoming more relevant and of interest to me... |
*The body of an elderly person is substantially different, physiologically, from that of an adult in that there's a decline in the efficiency of various organ systems in the body. However, there is a difference between disease and ageing effects; e.g., renal impairment may be a part of ageing but renal failure is not, etc.
World Health Organization's (WHO's) definition of "health"
The most famous modern definition of health was created during a Preamble to the Constitution of the World Health Organization as adopted by the International Health Conference, New York, 19-22 June, 1946; signed on 22 July 1946 by the representatives of 61 States (Official Records of the World Health Organization, no. 2, p. 100) and entered into force on 7 April 1948."Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity."
The Definition has not been amended since 1948.
During the Ottawa Charter for Health Promotion in 1986, the WHO said that health is:
"a resource for everyday life, not the objective of living. Health is a positive concept emphasizing social and personal resources, as well as physical capacities."
Vitamin D Revealed

Vitamin D Pills Are of Little or No Benefit and Some Harm. So What to Do Now?
by John A. McDougall, M.DSunlight is the Best Way to Raise Vitamin D Levels in the Body
Sunlight, in UVB wavelengths of 290 to 315 nm, is the natural and most effective way to produce vitamin D in the body, and an estimated 90% of our daily body requirements are met by sunlight exposure. In the summertime, exposure of a large surface area of skin for 20 to 30 minutes can produce approximately 10,000 IU of vitamin D in White people. A dose that causes redness of 6% of the skin is equivalent to the ingestion of 6001000 IU of vitamin D. (The Scientific Advisory Committee on Nutrition and National Institutes of Health recommend 200 IU daily.) Exposure during the spring, summer, and fall of the hands, face and arms two to three times a week is sufficient in White people. Asian-Indians may require 3 times, and Blacks may require 10 times as much exposure as Whites under the same sunlight conditions. Changes in the amount of vitamin D in the body are primarily regulated by sun exposure, and not by the diet.
The amount of vitamin D you have in your body during the winter months is based on the vitamin D you produce during the spring, summer, and fall. The vitamin D made in the sunshine months of the years is stored in your body fat and slowly released during the darker months. Plasma concentrations of 25-hydroxy vitamin D (25-OHD) in winter of 15.0-22.5 nmol/l require that the concentration in the previous summer was over 40 nmol/l.
Ultraviolet radiation is natural and provides benefits far beyond the production of the hormone called vitamin D. Apart from vitamin D synthesis there are a number of known ways that sunlight can affect a persons health. Some of the discovered mechanisms involve the direct alterations of the immune system, locally and systemically; modulation of other hormones like melatonin, calcitonin, and melanocyte stimulating hormone; and changing the number and function of cells present in the skin. Sunlight also establishes circadian rhythms. Undoubtedly, many important mechanisms for the benefit of natural sunlight remain to be discovered.
Exposure to sunlight for extended periods of time does not cause vitamin D toxicity. However, overexposure from the sun or a tanning bed can cause skin damage.
Antibiotic Drug Resistance -
Evolution Strikes Back
by Bill Nye in his book, Undeniable (Evolution
and the Science of Creation) p. 201.
"Do you get a flu shot every year? You should, because influenza (flu) viruses are evolving right under your vulnerable-to-infection nose, and you need to keep up. Viruses make their living by infecting living cells and inducing them to make copies of the virus. Those replicas pour out and encounter nearby cells, which results in more infection and yet more copies of the virus. If you think that sounds like war, you're not far off. In the winter of 1918-1919, the Spanish Flu killed about 50 million people - more than all of the combat in World War I, which had only just ended. Keep in mind that there is no evidence that viruses are malicious. They are just following their evolutionary path, multiplying whenever they encounter a survival advantage. The frightening thing is that the mindless, relentless drive of natural selection is now overwhelming our best defenses, making once-tamed disease dangerous all over again."
