Three little-known sleep tips for better rest

Don’t rely on catching up on sleep to erase sleep debt; maintain a consistent schedule and consider a short 20-minute nap if you’re short on sleep. Aim for about 6.4–7.8 hours of sleep per night—the “sweet spot” for better brain, heart and immune function. If sleep remains difficult, talk with a doctor about supplements like melatonin or magnesium, noting magnesium has less evidence but may help with muscle relaxation.
