Some of us tend to believe that sun only causes skin damage in summer. That’s not true. Just because you cannot feel the heat does not mean that it’s not there or that the sun’s rays are somehow less harmful in winter. You need to protect yourself from the sun just as much in winters as you do in the summer. The sun’s harmful radiations can cause a lot of skin related issues. If ignored for long, it can also lead to skin cancer in longterm. You should always use sunscreems.
Why you should use Sunscreens
Firstly, we realize that since winters are having zero sunlight in days, therefore, you definitely need sunrays to feed you the required quantities of vitamin D in summers. However, since the sun rays are very strong. Eventually, they cause sunburns on your delicate skin. The sunscreens protect your skin from these burns and damage of UV rays.
What SPF (Sun Protection Factor)?
So you must have read this SPF number on the sunscreens. This is the measure of protection from UVB. It ranges from 1-45 and more than that. This SPF is supposed to filter out almost 90% of the harmful UVB rays.
Higher SPF’S Better Or Not?
The SPF 30 is found out to block almost ninety percent of the harmful sun rays. If you are using SPF greater than 30 than it will block more percentage of the harmful sun rays. However, no sunscreen can completely block the sun rays. If you are using higher SPF than you need to reapply the sunscreen after every two to three hours.
These should have been able to convince you to get a sunscreen and use it at all times especially if your skin is directly exposed to sun rays. But even if its indirectly exposed, you need to use a sunscreen.
