Is it essential to apply sunscreen during winter?

Question

Hello doctor,

I am very conscious about protecting my skin from sun damage, so I diligently apply sunscreen every day during the warm spring and summer months. However, I have always wondered if it is really necessary to continue this practice throughout the winter season as well. The sun does not feel as strong, and I do not spend nearly as much time outdoors when it is cold outside. Could you please explain to me the reasons why sunscreen is still important during the winter months? I would like to understand the specific risks and how factors like cloud cover, snow glare, and the sun's angle in the sky might impact my exposure to harmful UV (ultraviolet) rays, even on shorter, chillier days.

Thank you.

Hello,

Welcome to icliniq.com.

I understand your concern.

The ability of sunscreen to shield skin from UV (ultraviolet) ray damage and premature aging is one of its key advantages in the winter. UV rays can reach your skin year-round and can pass through glass, snow, and clouds. Dermatologists claim that using a broad-spectrum sunscreen with an SPF (sun protection factor) of 15 or higher on a daily basis can cut your risk of melanoma by 50 percent, squamous cell carcinoma by 40 percent, and premature skin aging by 25 percent. Adding moisture to your skin, which gets drier and more sensitive in the winter, is another advantage of wearing sunscreen. Sunscreen can also shield you from sunburns, which can happen even in the winter, particularly if you are near snow or ice that reflects sunlight. Sunburns can impair your immune system and raise your risk of developing skin cancer.

Wintertime sunscreen disadvantages include its potential costs, inconvenience, and environmental damage. Sunscreen can be very expensive, particularly if you apply a generous amount and use it every day. Additionally, sunscreen may leave your skin or eyes feeling greasy, messy, or irritated. Certain components of sunscreen, such as oxybenzone and octinoxate, have been demonstrated to harm marine life and coral reefs. They may also pose risks to human health.

Ultimately, the best course of action for striking a balance between your needs for vitamin D and sun protection is to heed the advice of your physician, who can assess your vitamin D levels and prescribe the right dosage and duration of sun exposure. In addition, you can use other sun protection techniques such as wearing hats, sunglasses, and protective clothing, as well as selecting sunscreen products that are safe, efficient, and environmentally friendly. Sun exposure, whether excessive or insufficient, can be harmful to your health.

I hope this information helps you, and please reach out if you have any doubts.

Thank you.
