Five Summer Health Myths—Debunked

Local Physician Sheds Light on Popular Misconceptions

NEWS RELEASE — July 5, 2007

BUFFALO, NY— Summer is a season of abundant health concerns. Many of these concerns are based on fact, and others are simply “old wives tales.” Dr. Matthew Bartels, pediatrician at Amherst University Health Center, part of Lifetime Health Medical Group, separates myth from fact on the top five concerns he hears during summer appointments.

Myth #1: You must wait one hour or more after eating before going swimming.

Fact: This myth comes from the theory that severe muscle cramps can lead to drowning on a full stomach. While it is true that digestion diverts blood flow to the intestines away from the muscles used for swimming, there has never been a documented case of drowning due to a full stomach, says Dr. Bartels. Neither the American Academy of Pediatrics (AAP) or the American Red Cross makes recommendations about waiting any amount of time after eating before swimming. It is still a good idea to avoid swimming with an extremely full stomach because it could potentially cause fatigue and nausea.  Casual swimming after light meals or snacks is safe.
 

Myth #2: Infants under six months old cannot use sunscreen. 

Fact:  In general, it is best to avoid exposing infants to sun at all, because they burn easily. If infants do go out in the sun, the AAP recommends they should be dressed in lightweight long pants, light-colored long-sleeve shirts and brimmed hats. Parents can also apply a small amount of sunscreen with an SPF of 15 or greater to the infant’s face, legs, neck and arms. For the best protection, put on sunscreen about 30 minutes before going outside with your baby, and reapply frequently if sun exposure is prolonged.

Myth #3: Poison ivy rashes are contagious.

Fact: Poison ivy, oak and sumac rashes are not contagious. These rashes are actually delayed allergic reactions to oil called urushiol that is found on the plants. About 50 percent of people are allergic to urushiol. The rash itself is not contagious, no matter how much oozing and crusting occur. Once the oil is washed off the skin and clothes there is no risk of “spreading” the rash.
If the oil remains on clothes, shoes or other items, there can be re-exposure or new rashes, warns Dr. Bartels. Every item of clothing (and bedding) that might have retained plant oils should be washed separately from other clothing or linens, he says.

Myth #4: As long as I’m wearing a helmet during outdoor activities, like riding a bike or rollerblading, I am safe.

Fact: Simply wearing a helmet is not enough; it must be properly fitted and worn the right way. AAP guidelines say helmets should be worn level on the head, not tipped in any direction. Straps should be fastened, and you should not be able to move the helmet in any direction. When buying a helmet, look for a label that says it meets CPSC safety standards. Helmets should also be worn when skateboarding, rollerblading, riding a scoter and even when using the popular shoes with built-in wheels called “Heelys.”

Myth #5: Sparklers are a safe alternative to fireworks for children.

Fact: There are no fireworks that are safe for children. Even sparklers, which look fairly harmless when compared to other fireworks, can reach temperatures above 1000 degrees Fahrenheit, and can burn users and bystanders. Sparklers can also easily ignite children’s clothing, causing severe burns, scars or disfigurement.

If you are ever unsure about the safety of a summer activity, ask your doctor. More information about summer safety can be found at the American Academy of Pediatrics, www.aap.org. Pediatric care is available at four Lifetime Health Medical Group locations, including the Amherst University, Hamburg, William E. Mosher and West Seneca health centers.
