The sun is the
There is another, more subtle way, in which the sun gives us energy. Regular, very mild exposure to sunlight enhance vitality, as though reflecting a strengthening of the life force. As much as sun-ripened fruit tastes much better than green picked fruit, we can also ‘sun ripen’ ourselves by careful exposure to the sun. The radiant energy from the sun is absorbed by the millions of nerve endings in the skin and transmitted to our whole nervous system. Supposedly, this is why people feel energised after a brief sun bath.
Vitamin D can be found in animal food, but not in plant foods. Vegetarians are excluded from vitamin D, unless small quantities of eggs and cheese are consumed. However, we don’t need to consume this vitamin, as it is easily obtained by careful exposure to sunlight. Vitamin D is important to maintain sufficient levels of calcium and phosphorus in our blood, in order to supply our bones and teeth. If there is a deficiency of vitamin D, our bones become soft and bent.
There is also a change of developing osteoporosis. This happens when the rate of absorption of old bones exceeds the deposition of new bone. Other factors, like sex, race, hormonal status, family history, level of exercise and our diet also affect the risk of osteoporosis. In growing children, adequate supply of vitamin D is very important.
The component of light that produce vitamin D is ultraviolet radiation. We have to expose ourselves direct to the sun, because the beneficial form of ultraviolet light (UVB) does not penetrate through window glass. We don’t need to be hours in the sun in order to get enough vitamin D. Ten minutes during a short walk will be enough.
We have to take care when exposing ourself in the sun. Our skin is not used to long periods of exposure in direct sunlight. Our skin can be easily damaged by long periods of exposure with the risk of skin cancer. The energy of the sun quickly become devitalising and exhausting. The best time to be in the sun is early morning, before 9 am, or late afternoon, after 4 pm. When we go outdoors, we filter daylight by wearing sunglasses and sunscreens, and the light is significantly altered from the real thing. Natural sunlight has become artificial light.
“Few health educators appreciate that the daily and seasonal variations in intensity and duration of sunlight regulate our biochemistry and biorhythms,” say Professor Ronald S.Laura and John Ashton, in Natural Health magazine in the August/September 1991 edition, “Daily exposure to natural daylight – far from being a threat- is part of nature’s blueprint for health.”
