Not Sleeping? 9 Ways It Could Be Your Bedroom's Fault

Wong explains that your melatonin production is extremely sensitive to light. "While our eyes contain a large portion of receptors for light, it turns out these receptors can be found in our skin too!" she says. "Even if you sleep an adequate amount, the quality of your sleep will be negatively impacted by a light or dimly lit room." For this reason, it's best to sleep in a pitch-black environment with all lights completely off. "The total darkness helps melatonin do its thing without interruption," she says. If outside variables are keeping your bedroom from being dark, consider purchasing blackout curtains or shades or using an eye mask at night.
