If you cannot record enough Z at night, your bedroom may not be as dark as it should be. Melatonin plays an important role in your circadian rhythm (sleep-wake cycle), telling your body when to fall asleep. Your body releases hormones in a dark environment, and when the environment is too bright, it interferes with the production of melatonin.

More importantly, light passing through the closed eyelids inhibits melatonin, sometimes causing sleep disturbance or poor sleep quality. Sleeping in a dark bedroom can improve your sleep quality, and this is where blackout curtains come in. These curtains that darken the room are made of a thick opaque material that can block all external lighting.

Whether it is your neighbor’s porch lights, street lights or natural sunlight, in the case of blackout curtains, the brightness will not shine through your windows. In addition, many can reduce noise and contribute to climate control. Blackout curtains come in a variety of sizes, colors, styles, fabrics and price points, so the choice that suits you depends on your taste, preference and budget.

Final verdict

If we can only recommend a set of blackout curtains, we will have to choose Rosdorf Park Brockham Solid Blackout Grommet Panels (check it out on Wayfair). These visually pleasing curtains feature a blackout polyester backing with a transparent overlay. In addition, they are easy to install and machine washable.

However, if you want to choose energy-saving and noise-reducing options for your bedroom, we recommend Eclipse Kendall Solid Blackout Window Curtains (view on Amazon), which has been tested in the laboratory to block light and sound and help you reduce utilities cost.

What to look for in blackout curtains


There are a variety of materials for blackout curtains to choose from. The most common is polyester (or microfiber), which is usually machine washable and wrinkle-resistant. You can also find blended fabrics, as well as linen and cotton. Although the situation is different, linen and cotton cloth tend to wrinkle more easily and are not always machine washable.


Blackout curtains are usually darker in color because darker tones can better block light and help you sleep better. However, you will also find some lighter fabrics, which usually have a thick backing to ensure that the light is not blocked. No matter which color curtains you use, make sure that the product indicates that it is a shading material, not just “darkening of the room”.


When buying blackout curtains, it is very important to carefully measure the height of windows and walls. You will want something that exceeds the length of the window and is wide enough to ensure that all light is blocked. As for the time they fall from the bottom of the window, the length is mainly a matter of preference. However, hanging long curtains an inch or two above the floor can make the room look bigger.

Frequently asked questions

  • What is the best fabric for blackout curtains?

    The best fabric for blackout curtains is microfiber, which is a polyester fiber. Unlike natural textiles such as cotton and linen, tightly woven synthetic materials tend to better block light and isolate rooms.

  • Can blackout curtains keep out the heat?

    Many blackout curtains on the market are energy-efficient, which means they can insulate hot air in summer and cold air in winter. By blocking natural light from the outside and reflecting it back out of the window, they help prevent heat from entering.

  • How to wash blackout curtains?

    Most blackout curtains can be machine-washed, but some options are hand-washed or dry-cleaned. When washing curtains in a washing machine, it is best to gently wash the curtains with warm or cold water, and then dry them at low temperatures.
