New Delhi: Sleeping with your face covered on cold nights provides a unique sense of comfort. As soon as you pull the blanket up to your face, a warm nest is created inside, protecting you from the cold wind, light, and sounds outside. Many people find this habit so relaxing that they prefer to sleep this way.

But what effect does this comfortable habit have on your body (Effects of Sleeping with Your Face Covered)? Let's understand why some people enjoy sleeping with their face covered in a blanket and what effect does it have on your body?

Why does covering your face with a blanket feel so good?

When we sleep with our face covered, a warm and secure environment is created inside. This warmth not only provides comfort but also relaxes the mind, which helps us fall asleep faster. The darkness and quiet under a blanket reduces mental activity and helps us relax more quickly. This is why sleeping with your face covered in a blanket is so appealing.

What effect does it have on breathing?

Sleeping with your face covered increases the amount of carbon dioxide in the blanket and reduces the amount of fresh oxygen. Repeatedly breathing the same hot, stale air can:

• May cause frequent sleep interruptions
• May cause morning fatigue
• May cause headaches, dizziness, or difficulty concentrating
• May increase symptoms in people with allergies, sinus problems, or asthma

What effect does it have on the skin?

Covering your face with a blanket increases moisture and heat around the skin. This can irritate the skin. The combination of hot, moist air and sweat can:

• Clog pores
• Aggravate pimples and irritation
• Could cause inflammation or redness in sensitive skin
• Also, exposure to dust, oil, and bacteria accumulated in the blanket for hours on end is harmful.

How does body temperature deteriorate?

Body temperature naturally drops slightly at night for deep sleep. However, if the face is covered, the body is unable to release heat, leading to problems like restlessness, sweating, dehydration, and irregular heartbeat. Furthermore, this temperature imbalance also reduces sleep quality.

Why is this dangerous for children and infants?

If young children and babies fall asleep with their faces covered, it can be very dangerous. They may not adjust their sheets or blankets, which can block their airways. This poses a risk of suffocation. Therefore, it is extremely important to always keep children's faces uncovered.

How to stay warm without covering their faces?

• If you prefer warmth, try these safe methods:
• Use layered blankets or a thick quilt, but keep your face uncovered.
• Wear warm clothing, socks, or thermals.
• Place a hot water bag near your feet.
• Choose breathable cotton bedding.
• Get the room slightly warm before bed.
• If you prefer darkness, wear an eye mask.
