How Much Sun Is Too Much Sun?

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!

How to Dress for Extreme Heat

Dress in loose-fitting, lightweight clothing if you plan to be outdoors during extreme heat this summer. Natural fibers such as cotton, linen and silk breathe to allow perspiration to evaporate, and certain synthetics such as Coolmax are designed to wick away sweat. “Loose, billowy clothes allow air movement next to the skin and help with evaporation,” Penn State professor Larry Kenney told Real Simple. You can find many lightweight and lightly used garments at the #thrift stores supplied by generous #donations to ClothingDonations.org — or #donate the ones you no longer need. Resale proceeds go directly to programs that benefit the nation’s #veterans. #BeatTheHeat #OutdoorLiving

Avoid Exertion During Extreme Heat Events

With #climate change making #weather extremes more unpredictable, even simple activities such as getting the mail or walking the dog can pose health risks when temperatures spike. Ingest fluids continuously during extreme heat events even if you aren’t engaging in a strenuous activity — it’s better to prevent dehydration than react to it or suffer heatstroke. “Extreme heat is one of the terrifying aspects of climate change, and it’s important that people understand how to protect themselves and others,” Columbia University professor Cecilia Sorensen told Scientific American last year. #BeatTheHeat #OutdoorLiving

Seek out Shade to Beat the Heat

Before the invention of air conditioning, people had to keep c#ool using the natural methods at their disposal. Staying out of the direct sunlight is the first rule, and #shade trees are the most cost-effective way to cool your outdoor spaces, Houzz says. Trees take time to grow, of course, but you can buy trees large enough to offer shade and plant them in the fall. For a quicker fix, try adding a pergola, awnings, ceiling fans or a misting system to your outdoor space. “The cool breeze provided by a misting fan can make outdoor living very comfortable on even the hottest days.” #BeatTheHeat #OutdoorLiving

Avoid the Risks of the Summer Sun

A perfect #summer shouldn’t have any mishaps, but the hottest and most active season of the year isn’t without its risks. Check the UV index and slather on the sunscreen before you go out in the sun, says MedStar Health. Light-colored, lightweight clothing can offer additional protection from the damaging rays, as will a wide-brimmed hat and sunglasses. Drink plenty of water and other fluids and keep a first aid kit at the ready. Be alert to signs of heat exhaustion such as muscle cramps, dizziness and nausea; be vigilant about water safety when visiting the pool or beach; and never, ever leave children and pets unattended in a vehicle. #PerfectSummer
