Understanding UV Index And Its Relation To Your Skin

By now we understand the harmful effects of UV rays from the sun. We know that the damage from sun exposure can lead to fine lines, wrinkles, and even skin tone in the long run. But have you heard of UV Index (UVI)?

How Is UVI Related To Your Skin?
It’s a simple equation, higher the UVI, higher will be the risk of getting sunburn, photo ageing, and in some cases, skin cancer in the long run. “A marked increase in the incidence of skin cancer is strongly linked with excessive UV radiation exposure from the sun and possibly artificial sources such as sun-beds. She also believes that UVI is an important vehicle to alert people about sun protection. Though we should always be wearing sun protection, those with sun sensitive skin can decide on their outside activity depending on the UVI like avoiding the beach on such days.

What to do if the UV Index is High?
UVI is usually reported at noon when the UV exposure is at its maximum. UV index of 1 means it’s at the lowest and 11 is the highest. “UV radiation is higher between 11AM and 4PM and highest during summers. If you live in a place where the UVI is usually higher, make sure to wear enough sun protection. Here’s what you can do:

  • Avoid venturing out between 11AM to 4PM
  • Wear SPF 30 or above and reapply every two hours. “Don’t forget the lips, rub them with a sun-protection lip balm,” says Dr Kapoor.
  • If out in the sun, seek shade. Wear a hat and a pair of sunglasses.
  • Wear protective clothing in dark shades.
