Sunlight has a marked effect on some of the imbalances in the body which are associated with heart disease. Sunlight deficiency could increase blood cholesterol by allowing squalene metabolism to progress to cholesterol synthesis rather than to vitamin D. Not only sunlight lower blood pressure and cholesterol levels, but the results of tests reported in the American Journal of Physiology in 1935 show that exposure to ultraviolet radiation can also increase the amount of blood ejected from the heart - the cardiac output- by as much as 39% . If sunlight does influence the functioning of the cardiovascular system to anything like this extent, one would expect to see more heart disease when and where there was less available solar radiation.
Since time immemorial, the therapeutic use of light has been known to people. Probably the first reference came from Hufeland when he wrote in his book "Even the human being becomes pale, flabby, and apathetic as a result of being deprived of light - finally losing all his vital energy". Albert Szent-Gyorgyi, the Nobel Prize winner, has recognized how profoundly light and colour affect us. He concluded that "all the energy which we take into our bodies is derived from the Sun". In the photo-synthetic process the Suns energy is stored in plants, which are in turn eaten by animals and humans. Digestion and assimilation by animals and humans is concerned with breaking down, transferring, storing and utilizing this light-created energy.
The human body is nourished directly by stimulation of sunlight or nourished indirectly by eating foods, drinking fluids, or breathing air that has been vitalized by the sun`s light energy. This light energy not only affects our physiological activities and moods.
In a nut shell, these findings along with those of many other highly respected scientists and physicians, seem to indicate that the human body is truly a living photocell that is energized by the suns light, the nutrient of humankind.
Osteoporosis is a disease in which bones become fragile and more likely to break. If not prevented or if left untreated, osteoporosis can progress painlessly until a bone breaks. These broken bones, also known as fractures, occur typically in the hip, spine, and wrist.
Any bone can be affected, but of special concern are fractures of the hip and spine. A hip fracture almost always requires hospitalization and major surgery. It can impair a person`s ability to walk unassisted and may cause prolonged or permanent disability or even death. Spinal or vertebral fractures also have serious consequences, including loss of height, severe back pain, and deformity.
The World Health Organization (WHO) describes osteoporosis as a silent epidemic. The WHO is now predicting that the number of hip fractures could increase six-fold to over six million by the middle of this century. This is why osteoporosis is being called an epidemic. The only one solution to get rid of this disease is simple and as free as safe exposure to Sun. In studies of elderly populations who have suffered a broken hip, up to 40% have been shown to be lacking in vitamin D. In UK, one in every three women and one in every 12 men are suffered with Osteoporosis.
Lack of sunlight does seem to make worse the disease. It has been recognized for over 2 decades that Vitamin D deficiency is associated with increased risk of hip fractures. Safe exposure to sun at safe periods of the day can very much prevent bone disorders in later life.
