With #summer heat arriving early, you have probably already found find yourself doing more in the sun this year. Whether you are a sun-worshipper or an air-conditioning aficionado, it pays to know how much sun is too much sun.
Everyone needs some sun exposure to produce vitamin D, Johns Hopkins says, which aids calcium absorption and builds bone density. “But unprotected exposure to the sun’s ultraviolet (UV) rays can cause damage to the skin, eyes and immune system” as well as skin cancer.
Much depends on a person’s complexion. Those with pale complexions and light eyes have less melatonin in their systems — the pigment that causes tanning. As a result, the amount of direct sunlight they can endure without damage or sunburn can be as little as 10 minutes.
People with darker complexions tend to have more natural protection against UV rays, and may be able withstand exposures of up to 60 minutes without protection, according to the National Institutes of Health. Regardless, everyone should be careful to limit exposure.
Applying a broad-spectrum, water-resistant sunscreen with a sun protection factor (SPF) of at least 30 to all exposed areas is a good start. Blocking sunlight is the ultimate protection; you can cover up with lightweight, long-sleeved garments and a wide-brimmed hat. Protect your eyes with UV-blocking sunglasses whenever possible.
The sun’s rays are strongest between 10 a.m. and 4 p.m.; a good rule of thumb is to seek shade if your shadow is shorter than you are. Awnings, tents and trees can help. You can also carry your own shade in the form of an umbrella, but remember that surfaces such as pavement, sand and water can reflect UV rays upward.

Warm weather makes for #summertime fun. But be aware of how much direct sunlight you can safely handle, and take the appropriate steps to protect your skin and eyes from excessive UV exposure whenever you go out. It’s important to your health!
