Tri Challenge: Kendrick takes on open water

Since January, six iReporters have been training in the Fit Nation Triathlon Challenge. We’re following along as they prepare to compete alongside Dr. Sanjay Gupta in the August 7 Nautica NYC Triathlon.

There comes a time in every triathlete's life when he  dips his  toe into open water. For the triathletes that train in the Chicagoland area, we are blessed with “Ohio Street Beach,” a sandy stretch of shoreline and marked swim along a breakwall on Lake Michigan. In the summer months, when the water temperature finally begins to rise to about 60, Ohio Street Beach becomes a mecca for triathletes.

Every Saturday and Sunday morning, you will find people squirming in and out of wetsuits and training at this site. It is a great place to practice swimming in the open water. There is a solid breakwall on one side, buoys to mark the ¼, ½, and ¾ mile swim and on a good day you can see the bottom of the lake below you.

For Kendrick, this was his first place to try open water swimming. It was yet another big step along his already epic journey. Not only was it the site of his first long swim, it was also the start location for his first three-hour training session.

Docs group urges mammograms every year starting at 40

In an effort to reduce breast cancer deaths, especially in young women, the American College of Obstetricians and Gynecologists  on Thursday updated its breast screening guidelines.

The primary change is that now the doctors say mammography screening should be offered annually to women beginning at age 40. The previous ACOG guidelines recommended women have mammograms every one to two years, beginning at age 40 and then receive them every year, beginning at age 50.

Get Some Sleep: Tips to combat the heat

Lisa Shives, M.D., is the founder of Northshore Sleep Medicine in Evanston, Illinois. She blogs on Tuesdays (or this week, on Wednesday) on The Chart. Read more from her at Dr. Lisa Shives’ Sleep Better Blog.

The recent heat wave across many parts of the country has been disturbing the sleep of many people who are not fortunate enough to have air conditioning.

This makes perfect sense because sleep is associated with a steady decline in our core body temperature. It should reach its lowest point approximately three hours before we wake.

Therefore, when we are overheated and this natural temperature drop is impeded, then sleep is disrupted.

Water frogs linked to illness in young kids

Frogs might be cute to look at but they might be hazardous to your children's health, which is why The Centers for Disease Control and Prevention  is warning parents to keep young kids away from water frogs and their habitats.

At least 241 people in the United States were sickened after being infected with Salmonella from African dwarf frogs.  More than two-thirds of the ill were under age 10,  and 30 percent of those infected were hospitalized, according to the CDC.  Health officials say these frogs are not safe pets for children under 5 years old.

"People need to be aware that these water frogs as well as other amphibians and reptiles can carry salmonella that can make people sick," says Dr. Casey Barton Behravesh, an epidemiologist at the CDC. "In this particular outbreak there is a unique strain that has been linked with African frogs associated with a single facility," she adds.
