Many people have difficulty sleeping at night. They are not relaxed when they go to bed, and their mind is racing through the morning.

This can often have a negative effect on their work performance during the day. Sleep experts will tell you that for a healthy and well balanced life, relaxation is vital. But how do you relax when your mind won’t stop chattering? One way is to use blackout curtains in your bedroom.

But are blackout curtains bad for you?

What Are Blackout Curtains?

With all this technology and advancement in the modern world, with night becoming day in big cities, and where streets are illuminated to an extent that it disturbs nature’s balance, blackout curtains help curb the excesses of artificial lighting and helps you sleep calm and undisturbed.

Blackout curtains have a few key benefits compared to regular curtains.  If you want to sleep well during the day, it is a good idea to invest in blackout curtains.

They will help ensure that the light from your windows won’t be magnified when you are trying to sleep during the day.

They block sunlight, making it easier to sleep during the day in your home. Some types of blackout curtains are also thermal, blocking heat and cold drafts as well.

Are Blackout Curtains Bad for You?

Are blackout curtains good or bad for you? In this article, we’ll investigate the good and bad sides of using blackout curtains to help you decide whether or not they are right for you.

6 Benefits of Blackout Curtains

#1 – They provide a better environment for sleep and rest

Blackout curtains help you sleep better by blocking out light from outside. Light can affect your sleep cycle, and if you have a room that has too much light coming in it can be distracting.

If you are someone who gets up early and needs to sleep in, blackout curtains will ensure that you get enough rest.

You may also want to consider using blackout curtains if you live in an area where natural light is more prevalent during the day.

This is especially true if you live near large windows or have large windows in your home. Blackout curtains will help keep sunlight out of your room so that it’s easier for you to sleep at night.

#2 – They prevent excess heat from entering your home

Blackout curtains are a great way to keep the temperature inside your home regulated. They prevent excess heat from entering your home, which is especially important in the summer months when it’s hot outside.

#3 – They give you a better sense of privacy

Blackout curtains provide you a better sense of privacy by blocking out light and preventing others from seeing inside your home.

In most cases, people living in apartment buildings will have to deal with bright lights shining into their windows during the night. This is particularly true if you live on the top floor, which will be more exposed to light than other floors.

If you have recently moved into a new apartment or house, you may have noticed that it can be very hard to get a good night’s sleep without being disturbed by outside noise or light pollution. Because of this, many people are turning towards blackout curtains as the solution to their problems.

#4 – They can provide anti-aging benefits

Blackout curtains are a great way to get more restful sleep, but they also help combat aging. Exposure to blue light has been shown to decrease melatonin production, making it harder for you to fall asleep and stay asleep.

By blocking out blue light with the use of blackout curtains, you can have better quality sleep and enjoy the anti-aging benefits that come from getting enough rest every night.

#5 – They can prevent type 2 diabetes

A recent study showed that people who slept with blackout curtains were less likely to develop type 2 diabetes. The reason: they get more sleep.

The researchers found that people who had blackout curtains in their bedrooms slept an average of 40 minutes longer per night than those without them.

That extra 40 minutes of sleep every night translates into a significant improvement in overall health, including weight management and decreased risk of heart disease and other health issues related to poor diet and lack of exercise.

#6 – They can have a calming effect

Blackout curtains can have a calming effect on the body, allowing you to fall asleep faster, stay asleep longer, and wake up feeling more refreshed than ever before. They help regulate your circadian rhythm, which can lead to better sleep patterns overall.

When it comes to regulating your circadian rhythm, there are two things that matter: exposure to light and exposure to darkness.

Blackout curtains block out light from outside sources like the sun, so that your body doesn’t think it’s still daytime when it really should be sleeping at night.

4 Cons of Blackout Curtains

#1 – They can make you feel tired

If you have a blackout curtain in your bedroom, then you may notice that it makes it harder for you to stay awake during the day.

This is because the curtains make your room darker than normal, which means that your body will tend to sleep more easily at night.

#2 – They can lead to over-sleeping (day and night)

The reason for this is that when an individual is in a dark room, the brain is tricked into thinking that it is nighttime and it sends out signals to the body to go into sleep mode. This means that the person will fall asleep much faster than they would if they were in a bright room.

#3 – They will prevent the natural light

The main negative effect of blackout curtains is that they prevent any natural light from coming into the room. This can be bad for your circadian rhythm, which tells your body when it’s time to wake up or go to sleep.

You may also find yourself feeling too groggy in the morning if you’re not getting enough sunlight during the day.

#4 – Toxicity concerns

Blackout curtains can bring about any toxicity concerns, especially if you have allergies. Even though they are made of cotton, there are lots of chemicals that are used in the manufacturing process.

This material is also treated with flame retardants and other chemicals that may cause allergic reactions.

Is It Healthy to Sleep With Blackout Curtains?

YES, it’s healthy to sleep with blackout curtains.

It’s also recommended that you get good sleep every night, and it’s easy to see how blackout curtains can help you get there. They block out light from outside, so you’re not woken up by the sun or street lights when it comes time to sleep.

And if you live in a neighborhood with lots of traffic noise, or if you have a neighbor who likes to play their music loud at all hours of the day and night, blackout curtains can help you get some restful sleep as well.

If you have any concerns about your health or safety related to using blackout curtains (for example, if they’re made with toxic materials), talk with your doctor before using them.

Do Blackout Curtains Make You More Tired?

When you sleep with blackout curtains on, it means that there is no light coming in from outside sources like street lights which could be very bright during the day time. This has a negative effect on your body because since the curtains block out the sunlight, your body would still think it has to continue resting.

What Are the Benefits of Blackout Curtains?

Blackout curtains are a solution to the problem of light pollution. Light pollution is the result of excessive artificial light that comes from street lamps, outdoor lights, and even your neighbor’s porch light.

This light can disrupt your sleep pattern because it prevents your body from producing melatonin, which is a hormone that regulates your biological clock.

Blackout curtains prevent this disruption by blocking out all outside light. They also keep the temperature in your bedroom lower than it would be otherwise because they block out heat from the sun. This allows you to enjoy more restful sleep at night.

Do Blackout Curtains Have Chemicals?

Some people believe that these synthetic drapes may contain chemicals that could be harmful to your health. However, most manufacturers claim that the fabrics used in their products meet all federal regulations for safety and cleanliness.

If you have concerns about the safety of your blackout curtains, you should contact the manufacturer directly for more information about their materials and processes for making them safe for use in homes and offices.

Are Blackout Cellular Shades Toxic?

Newer blackout cellular shades are not toxic, nor do they have any negative health effects. In fact, they’re designed to be used in homes and offices to help you sleep better–the goal is to block out light while still allowing fresh air into your home.

It’s important to note that older styles of blackout curtains may have been treated with harmful chemicals like formaldehyde, which can cause eye irritation and respiratory issues. If you have old blackout curtains at home or work, you should probably replace them.


A good approach to getting a good night’s sleep should be holistic. The best way to achieve this is through good sleeping habits, as well as making sure your bedroom is cool, dark, and perfectly quiet. This can be valuable on its own, but blackout curtains go one step further.

You can also add a great mood enhancer supplement such as Serenity, which encourages your system to have better rest and sleep, so you’ll feel more energized the next day.

As I always qualify, sleep is a vital part of any healthy lifestyle, and my goal with this post was to give you all the information needed to help you get the sleep your body needs.

I hope that you’re able to choose curtains that will improve your current sleep habits, and will allow you to enjoy that feeling of peacefulness whenever you enter your bedroom instead of dreading it. If you have any other questions or concerns, don’t hesitate to contact me.
