Unprotected sun exposure is dangerous
Sunlight consists of ultraviolet (UV) rays.
- UVA rays are present throughout the day, can travel through glass and are the most important cause of premature aging of the skin and contribute to skin cancer.
- UVB rays are most responsible for sunburn and skin cancer development and are most intense from 10:00 am to 4:00 pm
When to apply sunscreen
- Apply sunscreen approximately 30 minutes before being in the sun.
- Remember to reapply sunscreen every 2 hours or after getting wet.
How to apply sunscreen
- Be sure to apply enough sunscreen. As a rule of thumb, use an ounce (a handful) to cover your entire body.
- Use on all parts of your skin exposed to the sun, including the ears, back, shoulders, and the back of the knees and legs.
What to look for when you buy sunscreen
- Pick a broad-spectrum sunscreen that protects against UVA and UVB rays and has a sun protection factor (SPF) of at least 30, but SPF 50 is ideal for longer sun exposure.
- Look for sunscreen that contains zinc oxide or titanium dioxide as these metals reflect the sun’s rays instead of absorbing them like chemical based sunscreen.
