Dangers of Sleeping with a Blanket over the Head. Using Wearable Blankets Instead of Blankets

Everyone is different and our bedtime rituals differ, but we have one thing in common – we cover ourselves with a blanket (or more of them) in bed. Getting under the covers is one thing, but many people love sleeping with a blanket over their head. If you also have a habit to do that, this article lists all the reasons why you should stop.

Besides looking into why you should avoid having the blanket over your head while sleeping, we have reviewed some Wearable Blankets for both adults and for children. Wearable Blankets are highly recommended as they are devoid of risks of covering your head, as is with traditional blankets.

It’s in Human Nature to Cover During Sleep

couch sleep

When was the last time you went to bed without covering yourself using a blanket or any other type of covering? The answer is most likely – NEVER.

Going to bed without getting under a blanket seems odd, like it’s some sort of an unwritten rule.

One paper explored sleeping arrangements worldwide and it included foraging and non-foraging people who live in hot climates near the equator. Results showed that only nomadic foragers regularly sleep without any covering. The rest of the people across the globe use blankets, duvets, or other covering types when they sleep.

Blankets aren’t just protecting us from the cold, they are therapeutic too. Tucking yourself under a warm, fuzzy blanket helps manage stress and anxiety.

That said, you should avoid covering yourself over the head as much as possible. Why? Here are the exact reasons to cut out this habit.

1. Brain Damage

This isn’t a joke; covering your head while sleeping can contribute to brain damage.

Evidence shows that 23% of people who sleep with their head under the covers develop dementia. Dementia refers to a decline in mental ability severe enough to interfere with daily life. With Alzheimer’s disease being the most common form of dementia.

The reason why covering your head raises dementia risk is that it restricts airflow through the mouth and nose. Therefore, the brain receives insufficient fresh air needed for proper functioning. When this happens over a long period of time, it leads to the afro mentioned consequence.

2. Unclean Air

Even when you sleep, the body and brain still need air. However, when you’re covered by a duvet or blankets (or whatever you use), you don’t inhale clean or fresh air because you create a womb-like residence under the covers.

As a result, you inhale dirt, dust, and bacteria that are buried underneath your blanket. Basically, this seemingly innocent habit creates a dust-filled bubble for your breathing.

And in turn, inhaling particle-filled air can trigger your allergies, which further make sleeping uncomfortable. You also breathe dangerous chemicals and dust trapped in the weave of your bedding, Unappealing!

3. Increases Carbon dioxide Levels

A research studying the oxygen and carbon dioxide concentrations when covering your head was conducted. Participants were covered with one sheet and one blanket for 10 minutes, then with an additional one sheet and two blankets for 10 more minutes.

It was discovered that oxygen levels decreased to 18% from 20.9%, whereas carbon dioxide concentration increased from 0.4% to 2% in just a minute. Overtime, oxygen lowered to 16.5%, with  raising to 4.1%.

This doesn’t pose a significant threat to healthy individuals per se, especially when partaken once in a while. Prolonged covering your head, however, will result in less oxygen circulating in the blood and to the brain. Some people feel dizzy.

On the other hand, individuals with congestive heart failures or related conditions are at risk of a host of problems like arrhythmias and hypoxia.

4. Difficult to Fall Asleep

unable to sleep

Covering your head may impair sleep quality and lead to insomnia, yet another common sleep problem in the United States and other parts of the world. How does this habit contribute to insomnia? It could be down to overeating.

Although it’s probably comfortable to be tucked in like a burrito, some people may find it difficult to sleep when they’re feeling extremely warm or even sweating. Plus, sleeping can be difficult when covers over your head don’t allow you to breathe properly.

Besides, sweating throughout the night leads to clogged pores on your face and body, which causes acne breakouts and tangled hair.

5. Suffocation Risk

Even though covering your head while sleeping may seem incredibly comfortable, it carries certain risks too. One of these risks is suffocation, particularly if you already have some underlying condition such as asthma, sleep apnea, or cardiac disease.

People who have these conditions, including some type of lung disease, are at a higher risk of suffocation when they cover their head while sleeping. That is because they keep rebreathing the air they’ve just breathed out. This translates to less oxygen in the body overtime, which is hazardous.

6. Sleep Apnea Risk

Sleep apnea is a sleep disorder that occurs when a person’s breathing is interrupted during sleep. Figures show that 42 million Americans suffer from sleep-disorder breathing and 1 in 5 people have sleep apnea . Covering the head while sleeping increases suffocation risk in sleep apnea patients – and can trigger or heighten common sleep disorder risk. Why? Again, restricted airflow is to blame.

7. Lack of Alertness in Emergency Situations

The last thing you want while sleeping is to hear noises or face any sort of distraction. But, sometimes that’s necessary because it keeps you alive. Covers over your head reduce the influence of outside stimuli. In turn, you don’t hear some noises or notice any weird smells. This can be a bad thing in emergency situations like fire, break-ins, and other scenarios.

A seemingly innocent and comfortable habit of covering your head in bed can bring forth many risks. To avoid these unfortunate scenarios, avoid covering your head while sleeping. Your body and brain will love the fresh air, especially if you have a humidifier in your room.

If adjusting to sleeping without blankets proves difficult for you, start out with covering your head with a light sheet in lieu of the heavy blanket, then slowly work towards no blanket at all. The light sheet will offer breathability whilst still offering warmth and comfort.

  1. I already have sleep apnea, and use a CPAP. It seems to me that the only reason not to cover my head is your #6. I do, however, live with others, at least one of whom is very alert, even when sleeping.

  2. Hello Barc777,
    Sorry for the condition and I’m glad you have read and shared your thoughts. As per this article, #6 is the main reason. All the same, as times change and you probably may not be around the alert person(s) all the time, then you can gradually and over time train yourself to have your head uncovered as you sleep. It’s gonna do you a lot of good.

    What can I do to not to cover my head while sleeping?

    • What helps me when I sleep under the blankets I leave my nose and mouth poking out so I can breathe fine. :>

    • Hello Stacy and we really empathize with your predicament.
      Have you considered using bedding materials that are lighter on your upper quarter as you sleep?
      A light sheet (if the conditions are favorable), would be great as it won’t have much interference even if you covered your head.
      You may also consider some form of pegs that hold your blanket in a certain position while you sleep, such that you aren’t likely to cover your head. The ideal peg should be firm enough to deliver as desired.
      Above all, training yourself to do away with the habit would help, and as you grow, you may gradually outgrow the habit.

  4. Hello,
    I do sleep with my blanket over my head on occasion. Most of the time it is when I am napping in my chair in the living room. What is weird is I do it the most while fully awake. The noise level in my house is pretty bad sometimes so I will cover my head and tune it all out. I have felt the need to remove it because I feel suffocated.
    After reading this I will do what I have to, to stop. I already have memory issues and stuff. Thanks for the info!!

    • Hello Tracey,
      Kindly run a search on ‘CPAP hose cover’ and see if the results are close to what you’re looking for.

  6. So with all this face coverings with this virus situation, what will happen if you cover your face for 8 to 12 hours

    • It’s quite a worry, but as for the face masks, you can try and limit wearing them to when you’re interacting with people, and while in public places. While in-house, you can put them to rest. It is advisable.

  7. I cannot physically fall asleep without a blanket above my head…I just read all this and to be honest I’m a bit worried. I’ve been like this since I was born I’ve been sleeping with a blanket above my head for many years..I tried using sleep pills doesn’t work even sleeping with lights on doesn’t work…What should I do ? Is there a phobia related to this ?

    • Hi Max,
      It is human to always cover one’s head while sleeping. All the same, you might want to try ‘wearable blankets’ and see if they could help, in that your fore-face isn’t really fully covered.
      We have reviewed some of them in the updated version of this article.

  8. I used to do this all the time as a child, i remember being scared since i wached some scary movies and it feelt more secure under the blanket.

  9. I have always worried about people who cover their heads while sleeping because I personally feel I can’t breathe with sheets over my head…I see my husband or kids do this and I panic and make them uncover their heads. I also feel like I am suffocating while wearing a Covid mask. What do you think? I am seeing major cognitive dissonance everywhere in this regard..children can’t wear them because they will suffocate, but adults are apparently unaffected? I feel suffocated by the masks the same as I do with sheets. I am working hard to breathe and feel I may pass out (the feeling begins working seconds of putting it on). Every single “scientific” explanation I have read only confirms to me that mask wearing reduces ability to breathe…Major cognitive dissonance…that airflow spreads the virus so you must reduce air flow (Which means your ability to breathe is reduced)? But somehow oxygen is at 100%? So if there is reduced airflow, I’m dizzy, can’t breathe I am somehow making that up? But it is dangerous to put on kids because they might suffocate, and babies shouldn’t use blankets because of SIDS…don’t wear “breathable” masks because they “don’t work”…? So aaccording the experts, the only masks that “work” are the ones that don’t let you breathe or force you to work hard to breathe (kind of like when you have an asthma attack). So I wonder… what would you say is the difference between wearing masks made of three layers (if cotton, same materials as sheets) and putting your head under a bedsheet? I feel both are bad, and masks are worse bc they are designed to block airflow…

    • Hello, we have updated this article, and it may have a bit more content that tries to address some of the concerns shared of late.
      Meanwhile, we encourage you to continue wearing your masks, just as the health experts have been advising.

      However, there are various types of masks already in the market, and some are easier on the airflow, than others. One needs to go and get a mask that feels quite comfortable when breathing, but at the same time not compromising on the quality, as the mask is needed to serve the purpose of preventing the transmission of the Coronavirus.
      I have personally tried out a variety of masks, and found one that is quite comfortable on me.
      I may not recommend you to get any of them, but for sure you’ll find it if you try out a few samples in the market.

  10. Masks are unnecessary and harmful. Stop wearing them.
    There is no virus or any other disease that wearing a mask can protect you from. Unless you are in full body suit with alternate breating apparatus, a mask is simply a device of compliance and is actually against the laws of your state/s.
    Only criminals wear masks to hide their identity.
    Compliance wants you to hide your face under a face diaper to neutralize your identity…making you a non-entity.

  11. Are the non-baby blankets safe to walk in. What happens if there is an emergency?

    • These wearable blankets for kids are meant for sleeping in. It’s clearly unsafe to want to be walking in them, especially for kids.
