The history of sunscreen dates back to ancient Egypt when jasmine and rice bran extract were used to protect the skin from the sun. The first commercial sunscreen was invented by chemists in 1936 and since then, it has been improved to shield people’s skins from harmful rays from the sun.
Most people find the importance of applying sunscreen during summer, but what about winter? Winter has shorter days and cold nights and you may at times feel as if the sun is never out.
Well, you may pass by a bottle of sunscreen and decide it’s not important, but it’s equally important during the winter. Even though the sun is not entirely visible, it is still present and here are five reasons you should wear sunscreen.
1. UVA rays are the same strength throughout the year
Sunlight is the main source of ultraviolet radiation and about 5% of the UV rays from the sun reach the earth as UVB rays while 95% is UVA. Surprisingly, UVA rays remain unchanged even during the winter regardless of the fact that the sun is not very strong.
Basically, UVA rays have longer wavelength compared to UVB rays and this means that they penetrate deeper into your skin. According to research, UVA doesn’t cause sunburn but it causes skin damage and premature aging. Therefore, apply your sunscreen during the winter and maintain a glowing skin all year long.
2. Snow reflects UV rays
According to research, snow reflects nearly 80% of the sun’s rays whereas sand reflects only 17%. It could be fun playing in the snow especially on a sunny afternoon but be warned that it can result in a double dose of ultraviolet radiation.
If you are a skier, chances are that UV radiation may increase by four percent for every 1000 foot increase. Therefore, you need to wear sunscreen during winter months to protect yourself from wrinkles and skin cancer.
3. The ozone layer is at its thinnest during winter
The ozone layer is very important to all of us as it acts like earth’s sunscreen that filters out and offers protection from harmful ultraviolet rays by absorbing them before they could reach the ground. Unfortunately, the ozone layer is at its thinnest during the winter which increases your risk of sun damage from the harmful ultraviolet rays.
Therefore, you need sunscreen in winter to protect your skin sunburn. As a rule of thumb, look for products with a sun protection factor (SPF) of at least 15.
4. You can burn from the wind and sun
Sunburn and windburn are not a great combination and they could do more harm than good to your skin. Basically, freezing temperatures, as well as harsh winds, leave your skin agitated, dry and susceptible to ultraviolet rays.
Therefore, if you want to have glowing skin throughout the year, let wearing sunscreen be a necessity.
5. The sun is strong even when it’s cloudy
At times, we tend to assume that because it’s cloudy, we are safe from the harmful UV rays. Unfortunately, you’ll be surprised to learn that rays from the sun have a way of working their way almost through everything and experts estimate that 80% of rays pass through the clouds.
During the winter, most of the days are cold and cloudy and you should have a routine of wearing sunscreen on a daily basis which will help prevent premature aging and wrinkles, reduce the risk of getting cancer, keep your skin tone even and keep your skin healthy and moisturized.
In the world we are living in today, people are judging others by the condition of their skins. Well, harmful sun rays lead to sunburn, dry skin, and wrinkles which can affect someone’s confidence and self-esteem. Summer is not the only time to apply sunscreen as it should be a routine even during winter, and if wondering the reasons for that, this article will get you started.
