Why You Can’t Sleep Without a Blanket, Even on a Hot Night

In our quest for a perfect night’s rest, you might have noticed a peculiar behavior: the inability to sleep without a blanket, even on a hot night. Now, why is this so?

The Comfort Factor

The first thing to consider is comfort. According to research, blankets contribute to feelings of security and calmness, which can lead to better sleep. You can also think about it like a child’s comfort object — it’s not so much about the object itself but more about the feelings it elicits.

While you might argue that it’s easy to feel comfortable without a blanket on a warm night, remember that comfort is a multi-faceted concept. Yes, you might feel physically cool, but there’s a mental aspect to consider.

A blanket provides a sense of enclosure and protection, which can contribute to feelings of psychological safety.

Role of Habit

In addition to comfort, there’s the factor of habit. Once you go down the path of sleeping with a blanket, it won’t be easy to reverse this. Your body has grown accustomed to the sensation, and changes can disrupt your sleep.

However, if it becomes too hot, what you can do is switch to lighter blankets or even consider a sheet instead.

Weight and Deep Pressure Stimulation

More than just providing warmth, blankets — especially weighted ones — have been linked to the concept of Deep Pressure Stimulation (DPS).

DPS is present in various therapeutic practices, and its benefits include reduced anxiety and improved sleep quality. So, even on a hot night, the weight of the blanket can provide this therapeutic effect.

Body Temperature Regulation

While it might seem counterintuitive to use a blanket on a hot night, there are scientific reasons behind this. Our bodies have a specific temperature rhythm throughout the day, known as the circadian rhythm. This rhythm involves a drop in body temperature before it’s time to sleep, which can lead to feelings of drowsiness.

Being under a blanket, regardless of the room temperature, can assist in this process. The blanket traps your body heat, signaling to your brain that it’s time to sleep. In the wee hours of the morning, when the temperature typically dips, the blanket can provide the necessary warmth.

Practical Ways to Stay Cool and Covered

There might be nights when the heat is unbearable, but you still crave the comfort of a blanket. If possible, avoid heavy duvets and instead opt for a lightweight cotton blanket. Using breathable materials can prevent you from overheating while providing the coverage you’re used to.

You can also use a fan to circulate air in the room. Regularly flipping your pillow or moving to cooler areas of the bed can also provide temporary relief. If someone is still struggling, investing in cooling sleepwear or bed linens may be a worthwhile consideration.


So, there you have it. Various factors, from psychological comfort to body temperature regulation, can lead to our dependence on blankets for sleep. If you’re someone who can’t sleep without a blanket, even on a hot night, know that you’re not alone. Making smart choices about the type of blanket and your sleep environment can help you get the rest you need. After all, a good night’s sleep is something we all value, regardless of the weather.
