Many people find it difficult to sleep without a blanket, even in hot weather. This phenomenon can be explained by several factors, including the role of blankets in regulating body temperature, their association with sleep onset associations or rituals, and their ability to trigger feelings of safety and comfort. During sleep, our body temperature drops, and blankets help maintain warmth. Additionally, the physical sensation of being under a blanket can signal to our brain that it's time to sleep, enhancing sleep onset. Blankets also create a microclimate, providing a barrier that stabilizes the temperature around our skin, making it easier to fall asleep and maintain a restful state.

Blankets help regulate body temperature
The human body's core temperature drops as we fall asleep and continues to dip throughout the night, reaching its lowest point at around 4 a.m. This process starts an hour before we go to bed, and our body loses the ability to regulate its temperature once we reach the rapid eye movement (REM) sleep cycle. Blankets help us stay warm all night and prevent us from shivering.
Blankets create a microclimate—a barrier where the temperature doesn't change much. This warms up our skin, and the surrounding factors that cool down our body don't affect us as much. So, we fall asleep faster and have a better and less disturbed sleep.
During REM sleep, serotonin levels decrease. Serotonin is a neurotransmitter that encourages feelings of calm. The use of blankets, especially weighted ones, is associated with higher levels of serotonin, meaning they can help us sleep better. It may be that the heaviness of the bedding causes deep pressure stimulation that activates the parasympathetic nervous system, potentially increasing serotonin levels.
Weighted blankets may be especially beneficial for people with insomnia and anxiety. A 2015 study of otherwise healthy people with chronic insomnia found that those who slept under a weighted blanket reported having a calmer night's sleep. Additionally, a 2020 review of research suggests that people with anxiety may also benefit from using a weighted blanket.
The physical sensation of a blanket gets paired with sleep, so simply being under a blanket can cause the brain and body to be primed for sleep and trigger a sleep response.

They trigger a sleep response
The use of blankets, especially weighted ones, is associated with higher levels of serotonin, which is often referred to as the "happy hormone". Serotonin helps modulate sleep regulation, and lower levels of serotonin are often associated with insomnia. Blankets can also increase melatonin levels, which is another hormone that promotes quality sleep. The weight of a blanket can also mimic a therapeutic technique known as deep pressure stimulation, which is known to reduce cortisol levels and increase relaxation.
The physical sensation of a blanket can cause the brain and body to be primed for sleep. This is because blankets create a 'microclimate' around the skin that is usually warmer than the surrounding environment. They trap the heat that escapes from the body at night, keeping the body warm. As our body temperature continues to fall throughout the night while we sleep, blankets help prevent our slumber from being interrupted by cold shivers.
The use of blankets is also a matter of routine and conditioning. From being swaddled as babies to being tucked into our beds as children, we are accustomed to sleeping under blankets from the time we are born. Without them, our brain feels that something is missing and may find it difficult to relax.
Additionally, blankets provide a sense of security. As children, blankets served as a "magical getaway" that we believed would protect us from the darkness or ghosts. While we may have outgrown those fears, we continue to subconsciously relate a sense of security with blankets.

Blankets are relaxing and comfortable
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which is a "feel-good" chemical that plays a crucial role in keeping us happy and calm. When we are stressed and anxious, it is challenging to fall asleep. However, once we cover ourselves with a blanket, the amount of serotonin increases, promoting relaxation and comfort.
Weighted blankets have been found to be particularly beneficial for people suffering from insomnia and anxiety. A 2015 study published in the Journal of Sleep Medicine & Disorders revealed that participants with chronic insomnia who slept under weighted blankets experienced a calmer night's sleep. Additionally, a 2020 review in the American Journal of Occupational Therapy suggested that weighted blankets could also help individuals with anxiety.
Blankets provide a sense of safety and security. As children, we often had a fear of the darkness, and covering ourselves completely with a blanket created a magical getaway that fought our fears and made us feel protected. This habit of using blankets for comfort and security has been engraved in our routine since childhood.
Blankets also help regulate our body temperature. Our body's core temperature naturally drops as we fall asleep and continues to decrease throughout the night, reaching its lowest point around 4 a.m. Blankets trap the heat that escapes from our bodies, keeping us warm and comfortable. This temperature regulation is a key part of our circadian rhythm, which determines when our body is ready to fall asleep and when it's time to wake up.
The physical sensation of being under a blanket primes our brain and body for sleep, triggering a sleep response. It has become an integral part of our bedtime routine, and without it, our brain feels that something is missing, making it challenging to relax and fall asleep.

They are a key part of the circadian rhythm
Our bodies are programmed to sleep when it's dark and be awake when it's light, and this is all part of our circadian rhythm. This internal process regulates our sleep-wake cycle, and it's influenced by light and dark cues in our environment. When it's dark, our bodies produce melatonin, a hormone that makes us feel sleepy. Then, when it's light, our bodies stop producing melatonin, and we wake up. This is why many people find it easier to sleep in a dark room.
Using covers when we sleep is a key part of this circadian rhythm. When we get under the covers, we're creating a dark, enclosed space that tells our brains it's time to sleep. This is especially important if you're trying to sleep in a lit room or during the daytime. The covers act as a sort of 'cave', blocking out light and triggering our brains to produce melatonin, which helps us fall asleep and stay asleep.
Additionally, the weight of a duvet or blanket can also play a role in helping us sleep. The pressure of a heavy blanket can be soothing and calming, which aids relaxation. This sensation is similar to the feeling of being swaddled as a baby, which is a common technique used to help newborns sleep. The weight and warmth of a blanket can provide a sense of comfort and security, making it easier to fall and stay asleep.
For those who are particularly sensitive to light or have a hard time falling asleep, creating the right sleep environment is crucial. This includes making the room as dark as possible, maintaining a comfortable temperature, and using breathable bedding. By creating a soothing and light-controlled sleep environment, we can enhance the quality of our sleep and ensure we get the rest we need.

Blankets create a sense of safety
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, a "feel-good" chemical that plays a crucial role in keeping us happy and calm. When we are stressed and anxious, it becomes challenging to fall asleep. However, when we cover ourselves with a blanket, the amount of serotonin increases, promoting feelings of relaxation and safety.
Blankets create a microclimate, a barrier where the temperature remains relatively stable. This microclimate helps maintain our skin temperature, making us feel cozier and more comfortable. The stable temperature created by blankets also prevents external factors that could otherwise cool down our body and disrupt our sleep.
The physical sensation of being under a blanket is strongly associated with sleep. This association is so powerful that simply being under a blanket can trigger a sleep response, priming our brain and body for sleep. This association may have been conditioned since birth, as we have been using blankets our entire lives, making it an essential part of our bedtime routine.
The weight of a blanket can also provide a sense of safety and comfort, similar to how a child feels protected and comforted when wrapped in a blanket. This sense of safety and comfort can help reduce anxiety and improve sleep quality. Additionally, the heaviness of the blanket may activate the parasympathetic nervous system, potentially increasing the levels of mood-boosting neurotransmitters like dopamine and serotonin.
