We need the sun. The sun aids our body in producing vitamin D, which is essential for calcium absorption of the bones to keep them strong. But there are downsides to unprotected exposure to the sun. The sun gives off UV (ultraviolet) rays, which can damage skin cells. In the long run, it can cause premature aging and even skin cancer.
When Do You Need Sunscreen?
Sunscreen is essential all year round, even if it is the middle of Winter and cloudy. The sun’s rays are most harmful during mid-morning to mid-afternoon, so be sure to apply sunscreen then. You can even consult your phone’s weather app to see how high the UV Index is.
How Often Do You Need to Reapply Sunscreen?
Most sunscreen’s you purchase will tell you that you need to reapply your sunscreen once every two hours. It may be more often if you have been sweating or swimming.
Mineral or Chemical Sunscreen?
Mineral sunscreen contains zinc oxide or titanium dioxide. Chemical sunscreen contains avobenzone, octisalate, octocrylene, homosalate and others. Both sunscreens essentially act the same, taking the energy produced by UV rays and turning the heat negligible. If you have sensitive skin though, chemical sunscreen can sting, so mineral sunscreen can be an option. But the downside to mineral sunscreen is that it can often leave a visible layer of white. Depending on your skin and your personal preferences, pick the sunscreen that works best for you.
Sunscreen is Key
Whichever sunscreen serves you best, remember to apply and reapply, even when it is cloudy outside. The negative effects of too much UV radiation can cause harm to your skin over time, so it is best to prevent it. Use that sunscreen, seek shade when you can, and stay safe!
