EXPERT ANSWERS
Is there any link between cellphones and cancer?
The possible connection between cellphones and cancer is controversial. Many years' worth of studies on cellphones and cancer have yielded conflicting results. Learn more from Dr. Edward Creagan, an emeritus Mayo Clinic oncologist.

What's the best frequency for aerobic workouts?
Any type of aerobic activity contributes to cardiovascular fitness. Even dividing up your activity time, such as a few five-minute walks spread throughout the day, offers aerobic benefits. And longer, less frequent sessions of aerobic exercise have no clear advantage over shorter, more frequent sessions of activity. Learn more from Dr. Edward Laskowski, a Mayo Clinic physical medicine and rehabilitation specialist and co-director of the Mayo Clinic Sports Medicine Center.

HEALTH TIP OF THE WEEK
Too sick to exercise?
The common cold doesn't have to keep you on the sidelines. Mild to moderate exercise is usually OK if your symptoms are all above the neck, such as a runny nose, nasal congestion, sneezing or a minor sore throat. However, if your symptoms are below the neck, such as chest congestion, a hacking cough or an upset stomach, delay your workout. And don't exercise if you have a fever, fatigue or widespread muscle aches.
