Do Blackout Curtains Help With Sleep?
Do you feel like there is too much light in your bedroom at night or in the morning? Too much light in your bedroom could be severely interfering with your sleep. Here’s how blackout curtains can help.
Why does light affect your sleep?
Light is one of the key signals for your circadian rhythm. Your circadian rhythm is essentially your master ‘body clock’ that takes its cues from your general sleeping patterns, light exposure and temperature. This body clock starts facilitating the release of the sleep hormone melatonin about 2 hours before ‘bedtime’.
So, reducing your exposure to light at night time may help signal to your body that it’s time for bed and help you achieve a deeper sleep. This means you should be avoiding exposure to sunlight, reducing your screen time, and dimming the lights or lamps in your bedroom. Unless you live deeply rural, you will also need to find ways to reduce light from cars, streetlights and other homes entering your bedroom. That’s where blackout curtains come in.
What are blackout curtains?
Blackout curtain or lining fabric is made from dense, tightly woven materials that do not allow light through. Because the material is dense, blackout fabrics also have great insulation and noise-cancelling properties.
How blackout curtains help you get a better night’s sleep
When installed correctly, blackout curtains (or blackout curtain lining) almost completely stop external light entering your bedroom, and so contribute to an environment that allows a deeper sleep. They need to full cover the window frame for the blackout effect to work properly, so light doesn’t come through the sides. Blackout fabrics will also help reduce your energy bill and make it easier for you to control the temperature in your bedroom – another crucial factor for your circadian rhythm.

If your job or lifestyle mean you need to get your rest during daylight hours, blackout curtains are a fantastic way to reduce light exposure and ‘trick’ your circadian rhythm into producing melatonin.
