A perfect summer day is one without sunburn. But as this NASA photograph taken from the moon revealed, Earth glows with ultraviolet light — so blue it cannot be seen by the human eye. Overexposure to this invisible UV light causes sunburn.

“Do not worry about whether or not the sun will rise,” said entertainer Pearl Bailey. “Be prepared to enjoy it.”

Everyone can enjoy the sun... in moderation. According to the American Medical Association, we need sunlight for vitamin D, which helps our bodies absorb calcium. What we don't need is too much unprotected exposure.

It’s not hard to protect yourself. It just takes common sense, good sunscreen, proper sunglasses, and care. Be sure to protect your children too — a bad sunburn in childhood increases their risk for future skin cancer.

“Be like the flower, turn your faces to the sun,” wrote Kahlil Gibran... and don’t forget to reapply SPF-30!
