Exposure to light during sleep interferes with your sleep cycle, preventing you from the long and deep night’s rest you need to function at your best. The Nidra® Sleep Mask completely blocks out all light and visual stimuli so you can nap or sleep soundly anywhere.
Melatonin production, needed for deep, restful sleep, only happens in complete darkness. When you are sleeping in a place that gets any small amount of natural or artificial light or a partner in bed who still has lights on, you risk interrupting deep REM sleep. REM sleep is part of the sleep cycle that makes you feel restored and rested. If your REM sleep is disrupted even one night, your body won’t follow its normal circadian sleep cycle (“inner clock”) progression and can even take days or weeks to catch up.
