Be Safe in the Sun and Heat.

The sun drenches us with UVA and UVB radiation, which could give you a sunburn causing skin damage. The heat, on the other hand, is really only an issue when it gets above our normal body temperature, of 98.6.  For our purposes, we will discuss how to protect you from both of these threats.

Protection from the sun’s radiation:

If you’re going to be out in the sun, take all necessary cautions.  As goofy as it may look, a wide brim, light weight hat is ideal. It protects your scalp, back of your neck, shoulders, face and your ears. Ball caps are far less effective and leave your neck and ears susceptible to damage.  Since UVA and UVB radiation can damage your eyes, be sure that your sunglasses are rated to protect you.

Even if you wear the goofy hat, you still need a water proof SPF 45, UVA & UVB sunblock on all exposed skin from the bald spot on top your head to the V-neck of your shirt, both arms and the tops of your feet.  UVB is known to affect the outer layers of the skin. UVA radiation is less intense than UVB, but is more likely to reach deeper layers of tissue and cause damage.  Remember UV radiation is not stopped by clouds and is easily reflected off of water. It can get you when you’re not expecting it. Be sure your children are well protected at all times. If you use a spray on sunblock, do not inhale during application.

If you do sustain sun damage, call Déjà Vu Med Spa.  We have many treatments that can revitalize your skin and eliminate those unsightly sun spots.  Our sunscreens are actually good for your skin.

Protection from the heat:

Don’t stand in the sun unless it’s necessary, because it is 10° to 15° hotter in the sun than in the shade.  The low humidity in Arizona for most of the year makes our sweat process for cooling the body very effective.  As a result, we don’t necessarily realize how much water we are losing.  The key to safety and surviving the heat is hydration.  Water makes up 60% of a person’s body weight. For me at 190 pounds that comes to 13.7 gallons of water.  It may sound like a lot but don’t get overly confident.  If hiking at a normal pace on level ground on a 100° day, you will lose 1.0 to 1.5 liters of water an hour.  You only need to lose 2% of your water weight to start feeling symptoms of dehydration.  If you feel thirsty, dehydration has started.  At a loss of 5% the symptoms become severe and with a 10% loss the outcome could be fatal.

Water is the key. Consuming alcoholic or caffeinated beverages will only worsenen the dehydration.  Non- caffeinated sports drinks are a good choice, because they will help replace electrolytes lost through perspiration.
