Cotton Travel Eye Mask
Cotton Travel Eye Mask. The primary reason that those scientists say you need darkness for good sleep is actually evolutionary. Humans—and our pre-human ancestors—are naturally diurnal, meaning we’re awake during the day and sleep at night. For thousands of years before electric lights allowed us to keep working or socializing late into the evening, humans naturally slept while it was dark and were awake during the day. Our brains are hard-wired into associating darkness with sleep, and they produce more melatonin (the hormone that controls our sleep and wake cycles) when they sense an absence of light.
In addition to increased melatonin production, scientists have also linked dark sleeping conditions to increased time in REM sleep and decreased wakefulness—meaning you’re more likely to sleep deeply and to sleep through the night. And they’ve found these benefits with sleep masks, not just in dark rooms.
