Blackout Curtains: Do They Improve Sleep?

Light Pollution and Sleep Science

Studies consistently show that even small amounts of ambient light disrupt sleep architecture. Streetlights, car headlights, and early sunrises can fragment your REM cycles without you fully waking up.

What Blackout Curtains Actually Do

Quality blackout curtains block 95-100% of external light and reduce noise by 15-20 dB. They also insulate windows, cutting heating and cooling costs by up to 25%.

Choosing the Right Blackout Curtains

• Triple-weave fabric: Superior light blocking vs coated alternatives
• Floor-to-ceiling length: Prevents light leaks at the bottom
• Wraparound rods: Eliminates side gaps where light sneaks in
• Thermal backing: Adds insulation benefits

Beyond Sleep

Besides improving sleep quality, blackout curtains protect furniture from UV damage, create ideal conditions for shift workers, and help nurseries stay dark for daytime naps.
