A new research found out that sunscreens are offering more protection from the ultraviolet (UV) rays than umbrellas do. However, scientists say that neither of these mechanisms to avoid sunburns can fully protect people from the harmful rays.
The recent research was made on individuals who preferred using umbrellas and the ones who rather use sunscreen as a ultraviolet (UV) rays protector. According to lead author, Dr. Hao Ou-Yang, 78 percent of the people who use umbrellas get more sunburns than those who uses the sunscreens. However, a lot of people don’t know how to use and correctly apply the sunscreen lotions or sun protection creams.
Use sunscreens as a protection instead of umbrellas at the beach
According to lead author Dr. Hao Ou-Yang, he said that the sunscreen is more efficient than the umbrella. It doesn’t mean people shouldn’t use umbrellas when going to the beach or when exposed their skin to the sun rays but, he stated that umbrellas are not a substitute for sunscreens.
Around 78 percent of the people who use umbrella get sunburns more often than the ones who apply sunscreens on their skin, and from the last group, only 25 percent participants get sunburns. However, none of them offer 100 percent protection.
The research was made on 81 participants. All of them had fair skin and were asked to lay under the sun for almost 3.5 hours on August 2014 at Lake Lewisville, Texas. They laid down at middle of a sunny day. Some of the people received a standard-size umbrella as a shade while the rest received a sunscreen lotion of SPF 100.
A day later, the scientists studies the participants’ skin for sunburns on different parts of the body, including face, arms, back, and legs. The group of participant’s who were using umbrellas got 142 sunburns while the other group using sunscreen had only 17 sunburns. In total figures 32 participants with umbrellas had sunburns while only ten people affected in the group with sunscreen.
How to apply the sunscreens correctly?
SPF on Sunscreen means “Sun Protection Factor”, and it tells the duration of the protection offered by the sunscreen.SPF 30 sunscreen means that every 30 minutes the Sunscreen has to be reapplied to avoid the burning. It is important to understand that a high SPF does not have ingredients that protects more than those with a lower SPF. For example, SPF 60 is not twice as good as SPF 30. SPF 15 blocks about 94% of UV rays, SPF 30 blocks about 97%, and SPF 45 blocks about 98%. No sunscreen blocks 100% of UV rays
Most of the people use sunscreen lotions to protect their skin, however according to dermatologists and skin specialist, most people don’t know how to apply it correctly, or what the “SPF” in sunscreens’ labels stands for.
