Yoga in Sunny London

It’s the paradox of sunscreen. When you dutifully slather on the SPF 30 before heading outside on a sunny day, you’re protecting your skin 
from harmful ultraviolet rays. But you’re also preventing those rays from prompting your skin, liver, and kidneys to make an essential vitamin—vitamin D.
For more than 90 years, vitamin D has been known to play a role in bone health. But new research suggests that vitamin D may have many other health benefits. Vitamin D may play a role in reducing the risk of cancer, heart attack, and stroke. Emerging studies are examining the effects of higher doses of vitamin D on depression and autoimmune diseases like rheumatoid arthritis and multiple sclerosis.

Vitamin D occurs naturally in a few foods, such as salmon, egg yolks, and liver, and many other foods are fortified with 
it. The Food and Nutrition Board at the Institute of Medicine deems a vitamin D intake of 2,000 international units per day to be adequate for adults aged 50 and younger; older people need more. In light of new research, those recommendations are currently under review. But many of us aren’t getting enough even by the current recommendations. By some estimates, as many as three out of every four people in the UK aren’t getting enough vitamin D. While some nutritionists recommend seeking vitamin D by going outside for 10 or 15 minutes without sunscreen on a sunny day, dermatologists argue that’s neither a safe nor reliable way to ensure adequate vitamin D levels.

What’s the yogic message today? Read the label of your multivitamin to see if it contains the daily value of vitamin D, and ask your doctor to check your vitamin D levels 
at your next physical, if you’re concerned. And don’t forget your sunscreen and hat when you head for the beach.
