Help

Scientists say we need sunlight to produce vitamin D but too much tanning can put us at risk of skin cancer.

Professor Lesley Rhodes of the University of Manchester says the study will look at the risks as well as the benefits of being in the sun and will not just focus on those with pale and sensitive skin.
