Can Winter Sun Lead To Skin Cancer?

This article discusses the idea of using sun protection in winter, and if it is a good idea to apply sunscreen on cloudy days. The title alone can be confusing for some people, so we will get into more detail about this topic below. If you are looking for a way to stay safe from skin cancer this winter season, then read on!
In recent years there have been changes in how much sunlight exposure is needed by humans due to climate change. In fact, many regions around the world have been experiencing warmer winters with less snowfall and shorter days. This has led many people to wonder whether they should still wear sunscreen during these months when it’s cold outside or not?

Can Sunscreen Reduce The Risk Of Skin Cancer?

On the warmer days, when it is not snowing or raining outside, you still need to wear sunscreen. There are many reasons why this is true; two of them being that UV rays can penetrate through clouds and windows on colder days too!
So while you may think your risk for skin cancer has decreased due to winter weather conditions, it actually hasn’t. This also applies after sundown as well (when there’s no sunlight out). The sun emits harmful ultraviolet radiation even if we cannot see it in our skies during these months – so do not forget about protecting yourself from those pesky rays regardless of what time of day/night they come at us. You should always reapply sunscreen every two hours, especially if you are going to be outdoors for a long period of time.

How Common Is Skin Cancer?

Skin cancer is the most common form of all cancers in both men and women. When looking at a global scope, it has been found that over one million people are diagnosed with skin cancer each year. It should be noted that this number does not include basal cell or squamous cell carcinoma (those numbers would actually double).
When you think about those odds of getting any type of skin cancer, it makes sense to wear sunscreen! Skin Cancer can have lasting effects on your life if left untreated – so why do something now to prevent an illness later?

How To Treat Sunburns?

There are different levels of SPF and PPD (persistent pigment darkening) in sunscreen. The higher the number, then typically it is protecting you from more harmful rays!
  • SPF 15: 95% – 98% UVB protection; about average for daily use.
  • SPF 30+: 97% - 99%; a good choice if spending a lot of time outdoors or at the beach.
During the winter the UVB rays are not as strong, but UVA rays still penetrate and cause skin cancer. If you do not want to use sunscreen with a high SPF rating then at least apply one that has an adequate amount of UVA protection.

What Type Of Sunscreen Should You Use?

You should try using Physical sunscreens (zinc oxide or titanium dioxide) instead of chemical ones, like the popular Oxybenzone for example. Chemical sunscreens absorb into your skin before it turns UV radiation into heat energy; this is called phototoxicity.


If you want to stay safe this winter, it’s important to take precautions against the sun. This may seem counterintuitive because we’re thinking about staying warm and cozy inside our homes during the cold months of December through March, But spending too much time in the sunlight can actually increase your risk for skin cancer.
