One of the most important factors affecting sleep is light, which regulates our internal clock, or circadian rhythms. When light hits the retina, our body uses that information to determine the time of day. Because modern life is filled with artificial light—from streetlamps to smartphones—at all hours, our circadian rhythms are compromised, as is our production of melatonin, the sleep-promoting hormone. The consequences extend beyond adequate sleep to our health and well-being, contributing to stress, seasonal affective disorder, weight gain, and cardiovascular issues.

Research has shown the best way to ensure a good night’s sleep is to make your bedroom as dark as possible. That’s the idea behind blackout shades, which block external light so you can fall—and stay—asleep. In addition, the material muffles noise and keeps sun and UV rays out for an optimal sleeping temperature.

Hartmann&Forbes offers a large selection of performance fabric rollershades designed for light blockage. Featuring refined patterns and rich textures, most are PVC-free and Greenguard Gold certified.
