Sunlight is Vitally Essential

Anyone who has attempted to keep a houseplant alive has experience the life giving aspects of sunlight. If a plant does not get sunlight it will eventually die. Sunlight is important to human health as well. Unfortunately, over the last half century people have been warned about overexposure to sun, and that message has overshadowed the wonderful health benefits of sunlight.

There is no question that overexposure to the sun should be avoided. However, the vast majority of the scientific community believes that the “no sun” campaign has gone too far.[1] A whopping 70 percent of American kids aren’t getting enough vitamin D, and such youngsters tend to have higher blood pressure and lower levels of good cholesterol than their peers. Dr. Edward Giovannucci, a Harvard University professor of medicine and nutrition, stated that vitamin D might help prevent 30 deaths for each one caused by skin cancer.[2]

People getting too little exposure to sunlight has been linked to a HUGE number of ailments[3]:

  • Increased risk of cancer & poorer cancer survival
  • Type-1 diabetes
  • Decrease in insulin’s responsiveness
  • Multiple Sclerosis
  • Osteoporosis
  • Decline in periodontal attachment (loose teeth)
  • Cardiovascular disease
  • Low HDL-cholesterol
  • Premenstrual syndrome
  • Sleep disorders
  • Insomnia
  • Adult attention-deficit/hyperactivity disorder
  • Mental depression
  • Acne

Also it is important to note that in many cases sunlight deficiency causes no symptoms, but it can present as diffuse muscle and bone pain, and weakness, which can be misdiagnosed as fibromyalgia.

Vitamin D is a hormone that is formed within the body. It has the rare property of being formed by ultraviolet light rather than by an enzyme. In real life, approximately 90% of the vitamin D that people use is formed within the skin through the action of the sunlight-only 10% comes from diet and/or supplements.[4]

A low vitamin D level found in the blood is one sign of sunlight deficiency. However vitamin D is only part of the story. Apart from vitamin D synthesis there are a number of known ways that sunlight can affect a person’s 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.[5][6]

Luckily, for those of us that live in latitudes with less days of sunshine, we can charge up on sunlight in the warm months. Vitamin D is a fat soluble vitamin that is stored for long periods of time mainly in the liver and the fatty tissues. Plus, it does not take much time of exposure for us to produce a significant amount of vitamin D. For instance, a fair skinned person, sitting on a New York beach in June, in the middle of the day, for about 10-15 minutes (enough to cause a light pinkness 24 hours after), is producing the equivalent of 15,000-20,000 IU’s of Vitamin D. [7] People with dark skin need more exposure. Asian-Indians may require 3 times, and Blacks may require 10 times as much exposure, as Whites under the same sunlight conditions.[8] 

Here is the bottom-line. Sunlight is vital to life. Our bodies depend on us getting having exposure to sunlight at least some of the year. The health benefits are numerous. Go outside with some skin showing. Sunlight is vitally essential to becoming a Happy Deviant!!
