The Relationship Between Blanket and Sleep Quality

Why are blankets essential for sleep, especially during hot summers? How can we use them correctly to improve sleep quality?

Firstly, blankets help ensure our bodies get the necessary sleep by providing comfort, which enhances overall sleep quality. For example, our circadian rhythm, serotonin and melatonin levels, and the temperature we maintain during sleep are largely influenced by blankets or some form of body covering. While sleeping without a blanket in hot weather might seem like a good way to avoid overheating, it can actually negatively impact sleep quality.

Let’s take a look at why blankets are essential for sleep and explore ways to maintain or improve sleep quality, especially during hot summers.

Body temperature affects sleeping quality

Before we fall asleep, our core body temperature, related to the circadian rhythm, begins to drop. This natural process helps the body conserve energy and redirects some of it to systems that still need to work, like the digestive system. During the 8 to 9 hours of sleep, the body continues to lower its temperature slightly for about 5 to 6 hours before stabilizing. During this time, we need some form of covering to prevent waking up feeling too cold. However, if we fully cover ourselves with a blanket, body heat can get trapped, causing us to wake up from being too hot. Therefore, you can choose a blanket with a higher QMAX value to help maintain your body temperature at a comfortable level, avoiding overheating or getting too cold, and thus improving sleep quality.

Sleep habits affect sleep quality.

From birth, we’re used to curling up under a blanket while sleeping. Just like babies are wrapped in blankets and children are tucked in, we continue the habit of using a blanket as adults. When we try to sleep without a blanket, our brain keeps signaling that something is missing, reducing the production of serotonin and melatonin, which makes it harder to fall asleep.

The quality of your blanket impacts your sleep

The right bedding is crucial for a good night’s sleep. For example, the breathability and comfort of the blanket you use can affect your sleep. In summer, a blanket that isn’t breathable can make you wake up sweaty in the middle of the night, which isn’t a pleasant feeling. Blankets made from natural materials are also healthier and more eco-friendly, benefiting your overall well-being.

Other factors, such as room brightness, surrounding noise, a bad mood, or even a fan running in the bedroom, can also affect your sleep quality.
