Being awoken by the sun is actually good for you, but there are times when darkening a room aids in sleep especially for napping children, shift workers or others with non traditional sleep schedules and for blocking artificial night time light such as from a streetlamp. Blackout curtains also are energy saving (keeping heat from escaping in the winter and the hot sun from heating up your room in the summer) and help block or muffle outdoor noise.

Benefits of blackout curtains:

Energy efficient:They can decrease the amount of money spent on heating and air conditioning because of the curtain's ability to reduce the amount of heat lost in cooler months and reflect heat in the summer.
