Is it Safe to Sleep with a Blanket over your Head / Face !

Sleeping with Blanket over your head is often a habit of some kids. Some do it to get rid of fear of darkness in the night, while some do it to get more warmth. Adults have their own reason to do that, such as using smartphone under the blanket to don't let anybody else know that. Most common thought that comes in the mind of an educated man is if we consume all oxygen inside the blanket then we might die. Here we are going to find if it is really possible to run out of oxygen by covering your head with a blanket.

Is it Safe to Sleep with a Blanket over your Head / Face ?
Yes it is safe only if you are a healthy adult and the blanket is not too thick.

Can i run out of Oxygen by covering my head ?
Usually blankets are not air-tight, so can't run out of oxygen. But if it is a thick fiber blanket then it may reduce the air flow. CO2 concentration near your face might also increase.

What if i can't sleep with my face open ?
If you can't sleep due to some light falling on your eyes (as some people have tendency to sleep in complete darkness), then you may use an eye mask to cover your eyes only. It may also help you if you feel some fear.

When you sleep with your head inside the blanket then oxygen level might decrease. A healthy adult can easily figure it out due to rise in pulse rate and uncomfortable breathing. He/she will automatically remove the blanket from his/her face without getting awake.
