The 6 Most Common Sun Myth

As you've notice, its not the same as before, the sun is really hot now a days, especially at noon, and you think bringing umbrella is enough think again. Here are list of common sun myth.

Myth #1: A suntan's fine, as long as you don't burn.

Reality: While even one sunburn may double the chance of eventually developing melanoma(the most serious type of skin cancer), your are still at risk even if they never burn. "The more sun your get, the more likely you are to develop certain skin cancer," says Martin Weinstock M.D., no matter what your skin tone. "Any tan indicates damage to your skin."

Myth #2: A beach umbrella blocks the sun.

Reality: It's not foolproof. Sand reflects 17 percent of UV radiation, so you're still exposed, says Dr. Weinstock. Nevertheless, its smart to stay in the shade when the suns rays are high; just make sure you're also slathered with sunscreen.

Myth #3 Sun can't penetrate through windows.

Reality: Glass filters out only one kind of radiation - UVB rays. But UVA rays penetrate deeper, can still get through. That's why many adults have more freckles on their left side than their right-its from UV exposure on that side through the car window when driving. To protect yourself, apply sunscreen to any areas (like your hand, forearms, and face) before getting into your car. If you're buying a new car, consider one with tinted windows, which keep out almost four times more UVA light than regular ones.

Myth #4 Too much sun screen causes vitamin D deficiency

Reality: You may have read that extra exposure to sunshine is needed to help your body make vitamin D. But according to ACS, the American Academy of Dermatologist(AAD), and the Skin Cancer Foundation(SCF), both kids and adult get plenty of this nutrient through multivitamins, vitamin D0rich foods( like milk and fortified orange juice). Also even if you're wearing sunscreen, small amounts of UV rays still penetrate your skin, and that's enough to help you body produce vitamin D.

Myth #5 If Its cool or cloudy outside, you don't need sunscreen.

Reality: According to SCF, up to 80% of the suns UV rays can pass through clouds. This is the reason people often end up with serious sunburn on over cast days if they've spent time outside with no sun protection. Even in the cold months, you need to beware: snow can reflect up to 80% of UV rays, increasing exposure. This is especially true if you're on a ski vacation-the higher the altitude, the greater your UV exposure.

Myth #6 Eighty percent of sun damage occurs before the age of 18

Reality: Contrary to previous estimates, recent studies show that we get less than 25% of out total lifetime sun exposure before age 18. That means you get the majority of it later on.

I agree with all of what you have laid out. I also wrote something about sunscreen that often done wrongly by most.
