spending time in Sunlight

Spending 20 minutes in the sun could help to lower your risk of heart disease, scientists have claimed.

Researchers at the University of Edinburgh found that exposure to ultraviolet light lowered the blood pressure of volunteers.

Scientists say the findings may lead them to reconsider current advice for sun exposure.

High blood pressure is one of the main risk factors in heart disease and stroke. Around a third of the population suffer from high blood pressure.

The scientists believe that UV rays in sunlight cause nitrogen stored in the body to be released into the blood stream, relaxing blood vessels and lowering blood pressure.

However, excessive exposure to UV light is also known to be a major cause of skin cancer, so experts have warned the public against spendnig too much time in the sun unprotected.
