In Need of Vitamin D? You Might Require Far Less Sunlight Than You Think


With the summer season going strong, getting your daily dose of vitamin D has become much easier. However, the intense sunny weather raises the question about how you should enjoy sunlight safely towards ensuring a healthy lifestyle.

It is important to know that a balance must be maintained when it comes to getting your daily dose of vitamin D out in the sunlight for the prevention of health risks. You must know that UV rays tend to be the main cause of skin cancer. However, ample sunlight is also required for generating vitamin D.

The amount of sunlight as nutrition that your body requires for generating the required amount of vitamin D would vary depending on your skin quality. This is deduced from the research performed by Professor Lesley Rhodes at the University of Manchester.

What is the Safe Level of Sun Exposure?

In an in-depth study at the UK-funded Cancer Research, Professor Rhodes along with her team studied the impact of exposing 39 individuals having different skin types to low levels of UV light. As the dosage of UV increased, there was an increase in both the levels of Vitamin D as well as in DNA damages as observed in the skin samples.

The findings of the research deduced that the danger is most prominent in the lower layers of the skin. For the darker skin types, major DNA damage was not detected at the lower level. It usually occurred at the surface of the skin. On the other hand, in the lighter skin types, DNA damage was observed throughout the skin layers. This implied that there was more danger in the lower layers of the skin.

Rhodes stated that people with darker skin could be encouraged skin for exposing the skin to the sun –without burning –for getting Vitamin D. However, people with lighter skin should aim at receiving lower dosages of UV radiation.
