Can running cause cancer?
The sun’s ultraviolet rays can cause skin cancer, and runners may be especially vulnerable . A study in Archives of Dermatology found that marathoners showed increased numbers of abnormal moles and age spots, putting them at higher risk for malignant melanoma.

Does sun help you race faster?
And here’s the kicker: time in the sun may also lead to faster race times , according to research presented at the American College of Sports Medicine conference in May 2014. After cyclists spent 20 minutes under a UVA lamp, they completed a 16-kilometre time trial faster than when they did it without the rays, says Chris Easton, an exercise physiologist at the University of the West of Scotland. ‘The large stores of nitric oxide released from the skin help more blood and oxygen flow to your muscles,’ says Easton. ‘Plus, by reducing the amount of oxygen the muscles use to produce force, the nitric oxide helps you go harder, longer.’ (The cyclists’ times were even faster than when they ate rhubarb and Swiss chard, which also increase circulating levels of nitric oxide, but to a lesser degree than the sun.)
Does sunlight help with blood pressure?
Recent research from Edinburgh University reports that the skin contains large amounts of nitric oxide, a compound that dilates blood vessels to reduce blood pressure and lower the risk of heart attack and stroke. Sunlight activates those nitric oxide supplies and releases them into circulation , says Richard Weller, a senior lecturer in dermatology who conducted the research.
The Cons of Running in the Sun
First off, some sun exposure is a good thing – it’s even recommended.

Why is the sun so low?

Scientifically speaking there is no consensus regarding which component (s) of sunlight (UVA/UVB/UVC) are carcinogenic. Since UVA/UVB/UVC proportions can change drastically based on the time of day, that means we really have no way of knowing what time of day presents the highest risk to our body as far as skin damage and cancer are concerned. Because of this, you should not consider UV exposure when deciding what time to run.
