Life on Earth as we know it couldn’t exist without the ultraviolet (UV) rays provided by the sun. In addition to the vital role the sun plays in the food chain by providing energy for plant life, UV light is important for human beings in helping produce vitamin D in the body. However, as anyone who has ever experienced sunburn knows, there is such a thing as too much of a good thing. In the case of UV light, overexposure can cause serious damage to skin and even lead to cancer. There’s nothing wrong with getting some sun. However, you need to use some protection if you’re going to be out in the sun for a prolonged period of time to ensure you’re not getting too much of a good thing.
Sunscreen is important to remember when you’re out and about on a sunny day. It’s recommended to use sunscreen with an SPF of at least 30 to provide the best protection. Sunscreens labeled “broad spectrum” provides protection from more types of UV light than products without that label. Water-resistant formulas are better because they won’t be rinsed away as easily during activities in the water or run off when you sweat. Another key factor when choosing a sunscreen is getting a physical sunblock as opposed to a chemical sunscreen with nanoparticles that absorb into the skin and get into the blood stream. For more information on this, check out this blog post.
Nourishing World sells two sunscreen brands that are physical sunblock and get a # 1 rating from the Environmental Working Group. These are Thinksport Regular and Kids Sunscreens, both have a 50+ SPF. The other brand we sell is Mercola Sunscreen, one has an SPF of 15, and the other has an SPF of 30. One last thing to remember about proper sunscreen use is to re-apply often, sometimes every hour in the worst of the summer months, to ensure you receive maximum protection.
Wearing clothing that covers as much skin as possible is another good way to stay protected in the sun. Be sure to wear long-sleeved shirts and wide-brimmed hats to receive the most protection. Dark-colored clothing provides more protection than light-colored clothing; and tightly woven fabrics are better protection than loosely woven clothing.
And finally, the easiest way to help shield yourself from UV rays is to keep to shady spots on very sunny days — especially during the late-morning-to-late-afternoon period when the UV light from the sun is at its peak. This includes when you’re on the sand or snow, because it can reflect UV light and increase the amount in which you’re exposed. Staying inside when UV light is strongest also helps, especially if the windows in your home or car are tinted to block more UV rays. If you’re thinking about having your car windows tinted to protect yourself from the sun, the amount of tint you are allowed to have may vary based on where you live. The following chart illustrates the amount of window tint permitted in each state. Now go enjoy the outdoors safely!
