Answer:
How long am I contagious when I have the flu or a cold?
As long as you have symptoms. Your ability to spread these viruses remains until the last sniffle, says Bill Schaffner, MD, a physician and infectious disease expert at Vanderbilt Medical Center in Nashville. And you're contagious 24 hours before you first show symptoms.
Are Short Workouts Worth It?
Yes. Longer is better, but you can get by with quick bouts of activity when that’s all you have time for. The CDC suggests 150 minutes of moderate-intensity aerobic activity each week (like walking or biking at a medium-fast pace), plus two sessions of muscle-strengthening exercise. Several 10- minute bursts of exercise each day can get you to this goal and help keep you fit.
Is Tap Water Safe to Drink?
Yes. The U.S. has some of the safest drinking water in the world. Unless your water comes from a small community system or private well, the Environmental Protection Agency (EPA) checks it closely for bacteria and harmful chemicals like lead.
