For more than 40 years, dermatologists have been telling us that direct exposure to the sun causes skin damage and skin cancer.
What they overlook, however, is the many important biological processes that take place in your skin during 'sensible sun exposure'.
There are numerous chemicals that are produced in your skin, including beta-endorphins that improve your mood and nitric oxide that lowers your blood pressure.
A Vitamin D supplement does not provide these chemical benefits.
Vitamin D production occurs approximately between 10am to 3pm during spring, summer and autumn. In the early morning or late afternoon the UVB to UVA ratio is very low and your skin is blasted by UVA radiation. The UVA can alter your immune system and increase your risk of melanoma.
