Real dangers or summertime myths?

CNN News - Summertime often means catching rays at the pool, lounging around on the weekends and forgetting about the rigors of life. But even summer carries a few rules that many people abide by.

However, how many of these rules are based on real science rather than myths? Below are some scientific breakdowns of popular summertime myths.

Myth: You can catch poison ivy from someone else.
False. Poison ivy is contracted from the oil of the plant. However be careful of oil getting onto tools, gloves, clothes or even pets as it is possible to pick it up from there.

Myth: Eating watermelon seeds can make you sick.
Nope. It is completely untrue that seeds can sprout within the body.

Myth: Tanning one time in a tanning bed can protect from the sun’s damaging rays.
No way! Tanning does not protect against developing skin cancer and tan skin isn’t protected particularly well from the sun’s rays.

Myth: You should wait 30 minutes after you eat to go back into the pool.
Depends… The digestive process requires blood flow to the stomach. If you distract your stomach by exercising and leading the blood flow to the muscles instead of the stomach it is possible that you might get some stomach cramp.

Myth: Going in and out of air condition can cause you to catch a cold.
Nada. Viruses, not cold air indoors in the summer, cause colds.

The best advice for a safe summer? Doctors say use common sense.
