Canada has a long season each year in which vitamin D from sunlight is not available. Due to the northern latitude of Canada, May through October is the only period when vitamin D can be produced in response to sun exposure to the skin. Therefore, a new press release from the Vitamin D Society recommends to protect health by building up vitamin D during the summer. Vitamin D from the summer sun helps to prevent serious diseases such as cancer, cardiovascular diseases, diabetes, multiple sclerosis and others.
Dr. Reinhold Vieth, the scientific advisor for the Society, states the following: We often assume that the health benefits of sunshine are solely due to vitamin D, but that is not proven yet. In other words, it is likely that sunshine does more for our bodies than just produce vitamin D.”
Dr. Vieth is correct. Vitamin D is only one of several products of sun exposure. Others are nitric oxide, which helps prevent vascular problems, and serotonin and endorphins that enhance mood. It is likely that there are many more products of sun exposure that enhance human health.
The Society recommends 6 guidelines for safely enjoying the sun and its health benefits:
- Be moderate, and don’t burn.
- Sun exposure can produce vitamin D only during the mid-day hours, so be outside between 10 AM and 4 PM.
- Know your skin type and risk of burning. Red hair and very light skin predict a greater risk of burning. (Also remember that dark skin needs more sun exposure to produce vitamin D).
- A gradual build-up of a tan protects the skin from burning.
- When the skin begins to redden, it is time to stop the sun exposure.
- Frequent but shorter sun exposure times are better for producing vitamin D.
Since about 35% of all Canadians do not meet suggested vitamin D requirements, sun exposure is essential to reverse that statistic.
So Canadians, safely enjoy the sun this summer!

In end stage kidney disease, heart disease and other vascular diseases are often the most dreadful accompanying disorders, also known as a comorbidities. Any healthful procedure that can mitigate the distress of these diseases can be a godsend to the patient suffering from kidney deterioration. UV therapy, similar to sun exposure, has now been shown to alleviate some of the difficulties of cardiovascular diseases and thereby increase the quality of life.
The research was conducted on fourteen kidney-dialysis patients. They were irradiated with whole-body UV for six months. Before and after that time, they were measured for several physiological functions to determine if there had been worthwhile changes in indicators of cardiovascular diseases. These were the results:
- Hematocrit increased, indicating a larger volume of red blood cells, which are important for carrying oxygen to the heart, vessels and all other parts of the body.
- The patients required less erythropoietin, a hormone that stimulates production of red blood cells and hemoglobin in case of low-tissue oxygen. This would indicate that oxygen need was reduced after the UV treatment, putting less stress on the cardiovascular system.
- In addition to, or perhaps because of, these positive changes, maximal oxygen uptake increased, indicating greater work capacity and physical fitness.
- Workload capacity increased and lactic acid production decreased, also indicative of enhanced physical fitness.
- Pulse rate decreased, indicative of an ability of the heart to deliver more oxygen per beat through the cardiovascular system. This is also a fitness measurement.
- Both systolic and diastolic blood pressures decreased, showing a healthier vascular system.
The researchers made the following conclusion: “Cardiovascular disease is the most important comorbidity [to kidney disease]. Exposure to simulated sunlight that contains both UVB and UVA reduce cardiovascular risk factors and improve quality of life.”
Protect your kidneys or protect your heart either by safe exposure to the “simulated sunlight” of sunlamps or tanning devices, or by regularly exposing yourself (again, safely) to mankind’s best friend the Sun.

Go ahead and soak up some sun! So says Dr. Holick.
It is great to have Dr. Michael Holick appearing in news articles occasionally, because he helps to stop the pervasive lies that frighten the public from partaking of life-saving sun exposure. A recent article appearing in the Washington Post, and written by Dr. Holick, makes some good points that all of us should have at our fingertips when being confronted by the anti-sun militants:
- The American Academy of Dermatology recommends never exposing bare skin to the sun, or even on a cloudy day, without sunscreen. [How about that for insanity!]
- The FDA calls ultraviolet radiation a carcinogen. [ridiculous]
- These messages cause widespread paranoia
- SPF 30 sunscreens reduce vitamin D production by 97%.
- A lack of vitamin D is associated with increased risk for Type 1 and 2 diabetes, multiple sclerosis, rheumatoid arthritis, Crohn’s disease, cardiovascular disease, stroke, depression, Alzheimer’s disease, schizophrenia, colon and breast cancer, influenza and tuberculosis.
Much of the rest of the article concentrates on putting the lie to the nonsense about hiding ourselves from the sun, as he talks about how vital vitamin D is for cancer, diabetes and other diseases. He then discusses the best way to get sunlight exposure. This is a must read!
