How much time in the sun do you need to stay healthy?
Sunlight is beneficial. It gives us Vitamin D, prevents insomnia, and wards off depression. It also causes skin cancer, cataracts, age spots, and wrinkles. So find out how much of a good thing you really need!
Ultraviolet B light is strongest 11:00am to 4:00pm. It gives you sunburn, but doesn’t pass through glass or reflect off surfaces.
Ultraviolet A light is very tricky! It does not cause sunburn, but still causes aging, tanning, and skin cancer. It does not have peak hours, but is strong all day. It can reflect off of sand and water, and injure you while you are in the shade. It can pass through office windows and some car and airplane windows. Therefore, sunburn is not an adequate way to judge if you have been exposed to too much sun.
So how much sun exposure/radiation is safe?
There is no way of exactly predicting this, but the consensus is 10-15 minutes of midday sun, three times a week without a sunscreen is more than enough to maintain Vitamin D levels and still keep safe.
Again, it depends on your situation. If you suffer from skin cancer, is very fair, or battling hyperpigmentation you would err on the side of caution.
So, the answers to these questions are…
Do you need sunscreen?
- Sitting in the shade…………for the most part yes! Remember the power of UVA Rays.
- Taking a long car trip (cloudy or sunny day) ……the answer is yes, especially if your windows are not specially tinted for UVA/UVB protection.
- Sitting directly in front of an office window all day….the answer is yes. Unless you are several feet away.
- Remember mountain vacations expose you to up to 10% more sun damage and radiation because the air is thinner, even on cloudy days.
- Early morning or late evening exercises…yes, still apply sunscreen. Unless it is dark and pesky. UVA light is strong at 12:00 noon as it is at 6:00 pm.
So have fun in the sun- but just be smart about it.
