Why Wear Sunscreen?
We’ve all been told repeatedly the importance of wearing sunscreen; reapply it every 2 hours, wear it if the UV index is over 3, and never forget to pack it in your beach bag.
Some people think sunscreen is only needed if they’re in the sun for a long time or on a vacation or beach trip rather than an everyday routine as recommended. The primary causes of both sun damage and skin cancer are ultraviolet rays, which are always present. It is important to apply SPF on either a sunny or cloudy day, even if you are only outdoors for 20 minutes.
The Effects of not Wearing Sunscreen
It may be obvious that being in the sun for too long without sunscreen can cause a sunburn. Serious long-term effects can arise, such as skin problems and cancer, if multiple sunburns happen. If the sunburn is severe, short-term effects can emerge, such as flu-like symptoms, dehydration, and confusion, or it could even cause you to faint or go into shock.
Too much UV radiation, especially sunburn, can damage the DNA in our skin cells. When there is too much damage to the DNA, cells can start to grow out of control, leading to melanoma and other skin cancers. Sunscreen can help reduce your risk of skin cancer by reducing overall UV exposure.
Too much sun exposure, specifically unprotected sun exposure, can cause increased and faster skin aging, which is called photoaging. Chronological skin aging is normal and cannot exactly be prevented; however, photoaging is preventable by using sunscreen daily.
Photoaging can cause the following:
- Leathery skin
- Skin discolouration and dark spots
- Dry and coarse skin
Weakened Immune System
Laboratory and Epidemiological evidence show that overexposure to UV radiation could impact how the immune system functions and the skin’s natural defences. When the immune system becomes weak from overexposure, it may reduce the skin’s ability to protect itself against infections and cancers.
Here are some little yet very effective ways to prevent the above long-term results of sun damage. Practicing these tips and remaining mindful of them while outdoors could tremendously protect your skin and guard your health.
