Health habits that are a 'waste of time'
Brush and floss twice a day
Brush and floss twice a day: In terms of dental health, once a day is fine. "Plaque takes 24 hours to harden," Dr. Mendelovitz says. "One really good brushing every 24 hours is better than two half-baked attempts." But commit to the job—spend at least 2 minutes. And do it before bed. Saliva combats plaque, and its production decreases when you sleep, Dr. Bader says. But remember: This is just about plaque. Your breath is still going to reek in the morning, so be a good coworker/friend/close talker and either brush or use mouthwash when you wake up. Another reason to floss every day: New York University researchers found that people who floss infrequently are three times more likely to develop stomach cancer. Jot down a plan of when, where, and how you'll floss each day and you'll be more likely to actually do it, a German study found.
