From mediation to melatonin to putting on a pair of socks, we all have routines to help us reach that blissful state of slumber. These are the ones that work: - Forget sheep. Instead, use mental imagery — picturing a walk in the woods or a stroll on a beach — to help relax. - Relaxation and meditation apps can help you unwind. - Melatonin supplements might ease your way into sleep, but too much melatonin could disrupt it. - Over-the-counter sleep medications may knock you out, but they won't result in effective sleep. - If young kids wake you in the wee hours, don't react in a way that increases their stress — but do find strategies that make it no fun to be up. - Sleep rituals are personal. If you believe in yours, that might be all you need.
