Sure, a small amount of exposure to sunlight can be healthy because it’s a good source of vitamin D, but keep in mind that more significant exposure to the sun’s ultraviolet (UV) rays can be deadly – sun exposure is responsible for thousands of deaths every year.
Every day, more than 9,500 people are diagnosed with skin cancer in the U.S., and at least two people die from it every hour. Sun exposure can also lead to the development of cataracts and premature aging of the skin.
Remember: Those of us who regularly work outdoors are especially at risk, as we can be exposed to 10 times more sunlight than people who primarily work indoors.
There are two key ways you can protect yourself from the sun: either by getting out of the sun or by putting some kind of barrier between yourself and the sun.
The simplest approach, obviously, is to avoid the sun as much as possible. That means working in the shade provided by trees, other plants, or man-made shelters whenever you can.
It also means being aware of the clock. Peak hours for sunlight are between 10 a.m. and 3 p.m. If possible, limit your outdoor activities during these hours, rotate activities with a buddy, or take frequent breaks.
If you can’t stay out of the sun, your next best option is to put something between you and the sunlight. That can be either protective clothing or sunscreen.
(What kind of clothing should you wear to protect yourself from the sun?)
But beware, not all clothing is equally protective. Select clothing that features dark-colored fabrics such as reds, blues and greens, which help prevent the penetration of damaging UV rays. Also choose clothing made out of tightly woven fabrics and/or fabrics with a high value of UV-ray protection.
You might think short sleeves and shorts are best when working in the sun, but that’s not actually the case. You’ll be better protected if you wear a long-sleeved shirt with a collar and long pants.
In addition, you’ll gain protection for your head by putting on a hat with a broad brim to shade both your face and the back of your neck. Also consider sunglasses with an eye protection factor of 9-10.
If your skin could be exposed to sunlight, select sunscreen with a sun protection factor (SPF) of at least 30. A lower SPF level won’t provide you with adequate protection.
Also remember: You should apply sunscreen at least 15 minutes before going outdoors, because it takes at least that long for your skin to absorb it.
Thanks for your attention. And remember, let’s stay safe out there!
