1/ Your Mind
SHELVE WORK WORRIES
Turn off your smartphone on schedule. People who stop reading e-mails and checking their phone at a set time each evening sleep better than those who don’t put limits in place, according to a Northern Illinois University study. A deadline helps you detach from work psychologically, researchers say.

2/ Your Eyes
DON’T BE ON THE LOSING SIDE
Try a new position in bed. An Australian review concluded that sleeping on your stomach can increase eye fluid pressure, which can raise glaucoma risk and worsen nearsightedness. Snooze on your back – unless you have sleep apnoea. In that case, sleep on your right side, Turkish researchers suggest.

3/ Your Teeth
SKIP THE RINSE CYCLE
Saliva washes away germs and bathes your teeth in restorative minerals. But as you sleep, you produce less spit, says Marilynn Rothen, a dentistry researcher at the University of Washington. Before bed, brush with fluoride toothpaste. Then spit but don’t rinse. You’ll leave a protective layer of fluoride.

4/ Your Skin
IRON OUT WRINKLES
Save face by applying a serum that’s rich in vitamin C and Retin-A, such as Multivitamin Power Serum on alternating nights, recommends skin therapist Sonette Donker. Why at night? Because sunlight might break down the active ingredients in these products.

5/ Your Heart
POP BEFORE YOU DROP
Scientists in the Netherlands say that taking 100 milligrams 
of aspirin at night can reduce the odds of a morning clot 
formation. Men tend to have 
a higher risk of heart attacks in the morning, so this strategy may help mitigate the danger, says Men’s Health cardiology advisor Dr John Elefteriades.
