Have a cavity filled in the afternoon
The painkilling effect of dental anesthesia lasts longer in the afternoon than it does in the morning. In one study, lidocaine kept nerves numb up to five times longer when it was injected in the early afternoon compared with early morning. Don’t miss these 11 home cures for toothaches.
Check your blood pressure in the morning and at night
As a general rule, blood pressure fluctuates throughout the day—it hits its lowest point around bedtime and it’s highest when you wake in the morning, says J. David Glass, PhD, a circadian biologist at Kent State University. If you’re keeping an eye on your blood pressure to help your doctor decide whether you need medication, you could get an inaccurate picture by taking your reading just once a day. “If you’re measuring it yourself, it’s best to do it in the morning and evening,” Glass says. “Be sure to do it at the same times each day—don’t bounce around.” Taking the two readings could make the difference between your doctor prescribing blood pressure drugs and advising you to stick with diet and exercise, he says. Here’s what else doctors don’t tell you about healthy blood pressure.
Weigh yourself on Friday and Monday
For those trying to lose weight, experts have long suggested stepping on the scale at least once a week—that’s the habit of most members of the National Weight Control Registry, every one of whom has taken off at least 30 pounds and kept it off for a year or more. Now research from the Washington University School of Medicine ratchets things up. Dieters tend to splurge on weekends, the research found—but a Friday weigh-in (especially done first thing in the morning, when your weight is lowest) provides positive feedback that can blunt the temptation to overeat, says lead study author Susan Racette, PhD. And getting back on the scale on Monday can help you correct your course quickly if you’ve strayed, she says. These are reasons your scale might be wrong.
