Why Do We Sleep Under Blankets?

After a long hard day, most of us just can’t wait to catch a few peaceful hours of sleep snuggled up under a nice cosy blanket. But have you ever thought about why we choose to sleep under blankets?

While blankets probably won’t protect you from whatever you think is hiding under your bed at night, there are actually several reasons why humans sleep better snuggling up under the covers.

3 Reasons We Love Sleeping Under Blankets 

It Keeps Us Warm

This might seem like the obvious answer, but at night when the temperature drops, blankets are there to keep us warm. Even in warmer climates people still use blankets when they go to sleep – even if it’s just a light sheet.

Our core body temperature tends to drop when we fall asleep, and when we reach the stage of REM sleep, our bodies are unable to regulate their own temperature. This makes it harder for us to keep warm especially since we experience REM in the early hours of the morning when the temperature is coolest.

Blankets are our best friends in this scenario, keeping us warm in the cold night air when our bodies can’t do it themselves.

Could it be because of something else? :s

It Can Reduce Stress

Sleeping with blankets have also been known to calm us down. Studies show that weighted blankets have an especially relaxing effect on users, commonly used to treat anxiety and insomnia.

These special blankets are used in deep pressure touch stimulation (DPTS), a non-drug therapy for relaxes patients naturally. The pressure on our bodies releases serotonin and relaxes the nervous system, making it easier to have a more restful sleep. Think of it as a nice warm hug!

We’re Used to It

Humans have never really needed to sleep under blankets. Before modern times when fabric was not mass-produced, blankets were actually considered to be a luxury that could only be afforded by the rich and powerful. Common folk would instead sleep next to each other to keep warm at night.

Fortunately, we live in a time when blankets are much more accessible to everyone. Most of us as children were tucked into bed by our parents, leading us to associate sleep with being bundled under the covers.

At the end of the day, using a blanket could just be behavioural conditioning – something we picked up from our parents from when we were babies.

Whichever position you like to sleep in – fetal position, the log, starfish pose, etc. – we know you’ll have your trusty blanket no matter what. At the end of the day, we might all just be kids at heart, wanting to be swaddled up under nice warm covers. Sleep tight!
