Q: How often should I switch out my toothbrush? - Lorraine, Newark, NJ
Every month or two. When your toothbrush gets wet, bacteria jump on board- “and the longer you have the brush, the more bacteria accumulate,” says Sherri Worth, D.D.S., a dentist in Newport Beach, California. (And bacteria can came from anywhere- including your mouth and even the air!) But time isn’t the only gauge: Worth says to toss a brush that has worn, frayed, or bristles going in different directions; ditto after you’ve had the flu or a cold. To lengthen the life of your brush, rinse it thoroughly after each use and allow it to dry completely before popping a clean cover over the bristles.
Q. Should you exercise if you’re still sore from a previous workout? - Kaitlin, Lakeland, FL
Unless you’re aching form a hugely intense effort- like a big race- you should power through, says Will Torres, a trainer and owner of Willspace, a personal training studio in New York City. “Light exercise will increase blood flow and help recovery.” Ease your muscle pain by changing your routine: If a cycling class left you hurting, do toga or Pilates; if you’re feeling limp from squats, work a different muscle group with pushups. Take it slow, lighten the weights when necessary, and say hydrated - H2O helps ward off soreness, says Torres
