Vitamin D helps regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth and muscles healthy. When your skin is exposed to sunlight, it makes vitamin D from cholesterol. The sun’s ultraviolet B (UVB) rays hit cholesterol in the skin cells, providing the energy for vitamin D synthesis to occur. If time is tight, what’s the one thing that you should be doing to improve your health and wellbeing? Getting some sun!
In this episode of ‘Just one thing’, Michael Mosely reveals the power of the sun’s rays to lower blood pressure and improve your mood, bones, muscles and immune system. He challenges TV presenter Mehreen Baig to sunbathe herself healthy, and speaks to Professor Ann Webb at the University of Manchester to shed new light on how going out in the middle of the day is the best way to boost your Vitamin D, and how to do it safely depending on your skin type.
