Hot workouts might carry some risks

This surprisingly hot summer weather can make it tough on your workout. But some people swear by it. Take, for instance, the hot yoga craze.

Experts say heat can help your workout by boosting circulation and increasing flexibility. But it's also a relationship that can turn nasty.

A 2011 study by the CDC found heat-related illnesses that strike during a sport or recreational activity send nearly 6,000 people in the U.S. to ERs every year.

Sometimes the problem is not the heat but the humidity. If it's too humid , your sweat can't evaporate, and this can prove dangerous, causing a heat-related injury such as dehydration, heat cramps or heat stroke.

Experts say the key to beating the heat is adequate hydration before, during and after exercise.
