Are curtains good for sleep?

Curtains can be very beneficial for getting better sleep. They block out light and noise that can interfere with sleeping. The right curtains improve bedroom conditions and sleep quality.

Are curtains good for sleep?

How Light and Noise Affect Sleep

Light and noise disrupt sleep cycles and prevent deep, restorative sleep. Curtains mitigate these issues in 2 ways:

Light Reduction

Natural and artificial light signal the brain to stay awake. Light reduction curtains keep bedrooms sufficiently dark for quality sleep.

Blackout curtains block out almost all external light for maximum darkness. They have dense, layered fabric or coated backing. These are ideal for sensitive sleepers or those working night shifts.

Room darkening and other thick curtains reduce incoming light significantly compared to regular curtains. These still allow some faint light through.

Light filtering curtains are lightweight and made of materials like linen or cotton. They block the harshest direct sunlight while still allowing some daylight into bedrooms.

Noise Reduction

Noises like traffic, animals, machinery and loud neighbors disrupt sleep. The right window coverings muffle irritating sounds.

Blackout curtains made of tightly-woven, noise-buffering fabrics lower noise pollution most significantly. Some have noise reduction ratings (NRR) indicating their decibel reduction.

Layered thermal curtains with pelmets trap air and create insulation. This substantially decreases outside noise. These are also excellent for better climate and temperature control.

Even lighter patterned curtains can marginally decrease noise by absorbing rather than reflecting sound waves. Lined curtains with pleats and heavier fabrics perform slightly better acoustically.

Optimal Bedroom Conditions for Sleep

In addition to darker and quieter spaces, ideal sleeping environments include:

  • Cool, not too warm temperature
  • Minimal disruptive noises like alarms
  • Comfortable, supportive bedding

Certain types of well-designed curtains promote these factors too.

Blackout curtains for daytime sleeping help maintain cooler conditions by preventing warming sunlight.

Thermal blackout curtains specifically regulate temperature. Some have metalized coating to reflect heat. They remain properly insulated year-round.

Noise reduction with most thick curtains eliminates interruptions from appliances or other household noises to support uninterrupted rest.

Pattern prints on lighter curtains can have soothing, sleep-inducing effects for certain individuals in bedrooms. relaxing environments promote healthy sleep cycles.

Curtain Design Considerations for Better Sleep

Address these elements when selecting curtains to transform bedrooms into sleep sanctuaries:


  • Opaque – Block maximum light. Vinyl and particularly densely woven polyester work best
  • Thermal insulating – Help retain desired room temperatures
  • Noise reducing – Softer textiles like velvet absorb more sound


  • Single lined curtains offer basic light filtering.
  • Double or triple lining equals greater light blocking and insulation


  • Darker colors prevent light transmission
  • Warmer tones like red and orange help create cozy atmospheres


  • More folded panels increase sound absorption
  • Pencil pleats with deeper folds are most effective


  • Metallic or acrylic backings boost light blocking and thermal insulation

Key Takeaways

  • Blackout curtains effectively minimize light and noise for better sleep
  • Thermal curtains additionally help regulate comfortable bedroom temperatures
  • Multiple curtain layers and insulating pelmets improve acoustic dampening
  • Features like opaque, noise-reducing fabric aid sleep quality
  • Consider specific design elements like color, pleating and linings based on bedrooms’ needs and individuals’ preferences
  • Prioritize blocking excess light and eliminating noise pollution for optimal sleep


Hanging well-designed curtains creates bedrooms conducive to healthy, rejuvenating sleep by controlling two key environmental factors – light and noise. Investing in suitable window treatments pays off with improved daily functioning, productivity and well-being over time from quality rest. Consider blackout or layered, sound-minimizing curtains to transform bedrooms into relaxing sanctuaries ideal for sleeping.

Q: Do blackout curtains make a room cooler?
A: Yes, thick blackout curtains provide extra insulation and block warming sunlight, helping make bedrooms cooler for comfortable sleeping temperatures.

Q: What color curtains are best for sleep?
A: Darker color curtains like navy blue block more light but also consider warmer tones like red or orange that feel cozy and relaxing for sleep spaces.

Q: Are blackout curtains bad for you?
A: No, blackout curtains aren’t inherently bad as long as you still get sufficient daily light exposure and vitamin D from time outdoors, while allowing better sleep regulation indoors.

Q: Do blackout curtains cause depression?

Q: How dark should a bedroom be for sleeping?
A: A bedroom should be as close to complete darkness as possible for best quality sleep, with blackout curtains helping achieve maximum darkness for restorative rest.

Q: Do blackout curtains look nice?
A: Yes, most modern blackout curtains feature stylish colors and patterns in attractive designs while still effectively blocking light, appealing for any aesthetic.

Q: Do thermal curtains keep you warm?
A: Yes, thermal curtains provide insulation that helps trap heat in during colder months for added warmth and comfort in bedrooms.

Q: Do double curtains reduce noise?
A: Yes, layered double curtain panels substantially muffle outside noises like traffic or loud neighbors for peaceful sleep compared to single panels.

Q: Are velvet curtains noise reducing?
A: Yes, velvet is an effective noise reducing curtain fabric that absorbs sound waves better than many materials due to its plush, dense texture.

Q: Do curtain linings provide insulation?
A: Yes, lined curtains have additional layers to provide more effective insulation and temperature regulation for better sleep comfort.

Q: Which curtain color is best for insulation?
A: Dark or warm colored curtains, especially in rich tones like red, perform slightly better thermally to retain more heat in bedrooms.

Q: Do noise reduction curtains work?
A: Quality noise reduction curtains effectively decrease external sounds by a meaningful amount so they disturb sleep less. Multi-layer blackout curtains with sound dampening fabrics work best to block noise pollution.

Q: Can you soundproof windows?
A: Yes, installing thick soundproof curtains over windows significantly reduces outside noise entering through glass for peaceful rooms conducive to quality sleep.

Q: What fabrics make the best blackout curtains?
A: The most effective blackout curtain fabrics are tightly woven, opaque materials like felt, faux silk, velvet, dense cotton, or vinyl laminates that completely block external light.

Q: Do blackout curtains need to be fitted to the wall?
A: For maximum light blocking, install blackout curtains extending wall-to-wall, using a tension rod or fitting them tightly to cover any gaps so no light peeks through the edges.

Q: Can you make regular curtains blackout
A: To make regular curtains more light-blocking, add blackout curtain liners underneath, use double rods for layered panels, or sew strips of hook & eye tape onto edges for tighter closing without gaps.

Q: Are blackout curtains OK for babies?
A: Yes, providing properly dark environments with blackout curtains promotes healthy sleep cycles in babies and young children when used correctly alongside sufficient daily light exposure.

Q: What thread count cotton is best for blackout curtains?
