UV Index

BillLeave a comment

Astronomical Spring begins on March 19. In addition to blooming trees and plants, the UV index is rising above the threshold where sunburn becomes an issue. My weather station has a UV sensor and I have already observed an increase in the UV index above the value of 2.UV Index 2020 When the UV index exceeds 2, skin and eye damage is possible. Suncreen with an SPF value of at least 30 should be applied. Stay in the shade if possible and wear a hat and wear sunglasses.

UV - Copy
The increased UV radiation does have some benefit. Your skin makes vitamin D naturally when it is exposed to UV rays from the sun. Vitamin D has many health benefits. It might even help lower the risk of some cancers. At this time, doctors aren’t sure what the optimal level of vitamin D is, but a lot of research is being done in this area. However, it’s better to get vitamin D from your diet or vitamin supplements rather than from exposure to UV rays. Dietary sources and vitamin supplements do not increase skin cancer risk, and are typically more reliable ways to get the amount you need.
