Despite sweltering temperatures, many people feel uncomfortable sleeping without a blanket. Some scientists attribute this to the body's natural circadian rhythm, which is tied to temperature. During the REM sleep cycle, the body loses its ability to regulate its temperature, and a blanket helps to maintain a comfortable microclimate. Additionally, the use of blankets, especially weighted ones, is associated with higher levels of serotonin, which can enhance sleep quality. From a behavioural perspective, sleeping with blankets may be a result of conditioning, as individuals have been using them since birth. However, some people prefer sleeping without a blanket due to personal comfort or excessive sweating.

Blankets help regulate body temperature, preventing you from waking up
Our bodies experience a natural drop in core body temperature right before sleep, which is a cue that it's time to sleep. Blankets help regulate body temperature, preventing you from waking up. During the night, temperatures drop, and our bodies lose their ability to regulate temperature during REM sleep. A blanket can help warm you up during these colder hours.
Even in hot climates, nighttime temperatures can drop, and a blanket can help you regulate your body temperature. For example, in tropical countries with high humidity, many people still sleep with a blanket. This is because blankets create a microclimate around the skin, which is usually warmer than the surrounding environment.
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which can help us sleep better. The heaviness of the bedding may cause deep pressure stimulation, potentially increasing serotonin levels.
If you are someone who gets too hot with a blanket, you can try adjusting your bedding. You can try lighter covers or layer your bedding and adjust your covers each night.

They increase serotonin levels, improving sleep quality
Serotonin is a chemical that carries messages between nerve cells in the brain and throughout the body. It is often referred to as the body's natural "feel-good" chemical. Serotonin plays a key role in several bodily functions, including mood, sleep, appetite, anxiety, digestion, blood clotting, and sexual desire.
Serotonin, along with dopamine, plays a role in the quality of sleep. It also helps the brain produce melatonin, a hormone that regulates the sleep-wake cycle. During REM sleep, serotonin levels decrease. The use of blankets, especially weighted ones, is associated with higher levels of serotonin, which can improve sleep quality. The heaviness of the blanket may cause deep pressure stimulation, which activates the parasympathetic nervous system, potentially increasing serotonin levels.
Weighted blankets can help individuals fall asleep and improve their sleep quality. The weight of the blanket matters, and it should be evenly distributed. A weighted blanket that is too light or too heavy may not provide the desired benefits.
Additionally, the perfect blanket should be warm enough to provide comfort without accumulating moisture and sweat. It should be soft enough to be easily adjustable while remaining substantial enough to be felt by the user.
The use of blankets is also associated with feelings of safety and security, which can further enhance sleep quality. By keeping the body temperature regulated, blankets prevent the core temperature from dropping too low, which can cause sleep interruptions.
In summary, the use of blankets, particularly weighted blankets, is linked to increased serotonin levels, which in turn improves sleep quality. The weight and warmth of the blanket create a sense of comfort and security, while also regulating body temperature, resulting in improved sleep.

Blankets are a source of comfort and security
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which can help us sleep better. The heaviness of the bedding is thought to activate the parasympathetic nervous system, potentially increasing serotonin levels in some individuals. This neurotransmitter is known for encouraging feelings of calm.
The body's core temperature drops right before sleep, and blankets help to regulate this temperature change, keeping the body warm and cosy. This temperature regulation is a key part of what regulates the circadian rhythm, which determines when the body is ready to sleep and wake up. During the night, temperatures drop further, and our bodies cannot adjust to this change, so blankets are essential to staying warm.
The presence of blankets is also linked to bedtime from a young age. We have been conditioned to use blankets since birth, and this association with sleep continues into adulthood. The weight and warmth of a blanket can create a sense of security and comfort, making it easier to fall asleep.
Even in hot climates, people tend to use some form of bedding or blanket. While a lightweight sheet may be preferred in these cases, it still provides a sense of coverage and protection.
The perfect blanket should be warm and comfortable, but also breathable to prevent moisture and sweating. It should be soft yet substantial enough to be felt, providing a sense of relaxation and security to help one drift off to sleep.

They are a form of 'pure conditioning', associated with sleep since birth
The use of blankets is a form of pure conditioning, associated with sleep since birth. Humans have been conditioned to use blankets since birth, as babies are worse at thermoregulation and tend to get cold easily. Thus, well-meaning adults put blankets on them, and getting under a sheet or blanket is associated with the process of falling asleep. This is similar to Pavlov's dogs drooling at the sound of a bell; we get sleepy when covered with a sheet.
The use of blankets, especially weighted ones, is associated with higher levels of serotonin, which is a neurotransmitter that encourages feelings of calm. The heaviness of the bedding may cause deep pressure stimulation that activates the parasympathetic nervous system, potentially increasing dopamine and serotonin levels. Thus, blankets can help us sleep better.
The presence of blankets may also trigger sleepiness as the body connects their presence to bedtimes. This is supported by the fact that even in hot climates, people use some form of bedding or blanket, and only nomadic foragers are known to sleep without bed coverings.
The need for a blanket during bedtime is also a product of conditioning. As humans have been using blankets since birth, they are easily associated with sleep. This is further supported by the fact that even when it is hot, many people still require a blanket to sleep, even if it is just a thin sheet.
Thus, the use of blankets is a form of pure conditioning, associated with sleep since birth, and they can help improve sleep quality by increasing serotonin levels and providing a sense of comfort and security.

Blankets can help trigger sleepiness, even in hot climates
Humans have a tendency to sleep under a blanket, even in hot climates. This is because blankets can help trigger sleepiness, even when it's hot.
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which encourages feelings of calm and sleepiness. The heaviness of the bedding may cause deep pressure stimulation, which could increase dopamine and serotonin levels. This is why, even in hot climates, many people still require a blanket to sleep.
During the night, temperatures drop, and the night is coldest right before dawn. While during the day, people in hot climates may feel they don't need a blanket, by the early morning, when it is coldest, a blanket can be necessary to stay warm. The body's core temperature drops before sleep, and a blanket can help to maintain this lower temperature, which signals to the body that it is bedtime.
The need for a blanket during sleep is also a product of conditioning. Humans have been using blankets since birth, so they are easily associated with sleep. This is a form of transitional object, in a Pavlovian way. Getting under a sheet or blanket is associated with the process of falling asleep.
To adjust to sleeping with a blanket in hot climates, it is recommended to gradually lighten your covers over several nights. This gives your brain time to adjust to the weight difference.
