    The index, which is compiled by the Environmental Safety Company (EPA), is calculated on a next-day foundation for dozens of cities throughout the US. The EPA considers 6-7 on the UV index to be “excessive threat.”

You might be most uncomfortable from the warmth at 5 p.m., when it’s 95 levels, however the solar is definitely stronger at 11 a.m. and also you’ll burn extra rapidly then. You may burn practically 1.5 occasions sooner at 11 a.m. versus 5 p.m.”

    UV and temperature

Actually, the UV index will be the very same on a extremely popular day and a chilly day.”

    Dermatologist Rebecca Marcus added, “There isn’t a transparent and particular hyperlink between warmth and UV and an elevated threat of pores and skin most cancers vs. UV radiation alone. However in case you’re contemplating the distinction between a sunny day within the winter vs. the summer time, then sure, we must be extra vigilant about sunscreen in the summertime, as a result of the solar is stronger in summer time and the UV index is greater, that means that there’s larger potential for harm.”

When the UV Index is low, this ‘reference’ particular person would have a low threat of burning when uncovered to peak solar between 10 a.m. and 4 p.m. for one hour. Because the UV index will increase, so does the danger.”

    These index numbers are price watching, dermatologists stated.

    If you wish to examine on the UV index however don’t have a smartphone helpful, do this trick: “In case your shadow is taller than you might be, the UV index is probably going low,” Kim stated. “In case your shadow is shorter, the UV index is probably going excessive, and it’s best to search shade and put on sunscreen SPF 30+ or greater.”
