Whether to sleep with or without a blanket is a highly debated topic. Some people prefer to sleep without a blanket, while others find that using a blanket helps them sleep better. The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which can improve sleep quality. Blankets also provide a sense of comfort, security, and protection from allergens. However, in hot weather, blankets can trap heat and increase the temperature, disrupting sleep. Ultimately, the decision to sleep with or without a blanket depends on personal preference, cultural norms, and the surrounding temperature.

What You'll Learn
Temperature regulation
The human body's core temperature drops before and during sleep. This nightly cool-down is a key part of what regulates the circadian rhythm that determines when the body is ready to sleep and when it is ready to wake up. As the body temperature drops, people tend to feel the need to sleep under a blanket.
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which can help people sleep better. The heaviness of the bedding may cause deep pressure stimulation that activates the parasympathetic nervous system, potentially increasing dopamine and serotonin levels. Warming the skin before sleep also helps people fall asleep.
However, the body temperature continues to decrease during sleep, and if it gets too cold, the body may wake up. Therefore, it is essential to use a blanket that is warm enough to keep the user comfortable without accumulating moisture and sweat. Thermoregulating blankets are the best option to maintain the right sleep temperature.
On the other hand, if the body gets too warm under the blanket, it may wake up as the body works to cool itself. This is more likely to occur in hot weather, where even a sheet can trap heat against the body. In such cases, it is better to sleep without a blanket to regulate body temperature.
Some people also prefer to sleep without a blanket due to personal preference or comfort. As long as a person is getting restful sleep and wakes up feeling refreshed, there is no right or wrong way to sleep.

Psychological comfort
The use of blankets can be attributed to both psychological and biological factors.
Blankets are often associated with positive childhood memories, which can have psychological benefits and promote better sleep. The feeling of being sheltered and secure adds to one's sense of security and soothes the instincts that protect us and prevent deep sleep. This sense of security may be linked to early childhood, when babies are wrapped in blankets and children are tucked into bed. The use of blankets may thus be a habit that continues into adulthood.
Additionally, in many cultures, sleeping with a blanket is considered a cultural norm, and people may feel more comfortable and secure adhering to this tradition.
The weight of the blanket also plays a role in psychological comfort. Weighted blankets, for example, are associated with higher levels of serotonin and can help us sleep better. The heaviness of the blanket can cause deep pressure stimulation that activates the parasympathetic nervous system, potentially increasing dopamine and serotonin levels.
The perfect blanket is one that is warm, breathable, soft, and substantial. It should be relaxing and help people drift off to sleep.

Physical barrier
One of the reasons why people prefer to sleep with a blanket is that it acts as a physical barrier. This barrier helps to protect the sleeper from the elements, such as a draft from an open window or a breeze from vents in the house. It also helps to create a microclimate that buffers against ambient temperature changes, allowing the sleeper to remain comfortable.
The physical barrier of a blanket can also provide a sense of security and comfort. Some people associate sleeping with a blanket with positive childhood memories, which can have psychological benefits and promote better sleep. The feeling of being sheltered and hidden can add to this sense of security, soothing the protective instincts that may prevent deep sleep.
Additionally, a blanket can act as a barrier between the body and the mattress, protecting against allergens and other irritants. This protective function is especially important for those who sleep on mattresses that are placed directly on the floor.
While some people prefer to sleep without a blanket, particularly in hot climates or during the summer months, the physical barrier that a blanket provides can help to improve sleep quality by maintaining a stable body temperature and creating a sense of comfort and security.
Therefore, the physical barrier of a blanket can provide both physical and psychological benefits, contributing to a more restful and uninterrupted sleep.

Culture and tradition
The use of blankets and bedding is influenced by a combination of cultural, historical, religious, and lifestyle factors. In some cultures, the concept of sleeping with blankets is relatively new, as blankets were historically a luxury item. For example, during the Middle Ages in Europe, only the wealthy could afford blankets, and bedding was often passed down in wills. However, as fabric became more affordable, blankets became commonplace, and even in tropical regions, many people now use some form of covering while sleeping.
In certain communities, such as the Maasai in Africa, cow hides are used as beds, and in traditional Japanese culture, sleeping on tatami mats and futons is preferred, with beds being folded and stored during the day to make room for other activities. In Arctic regions, the indigenous populations have used hammocks for centuries, and this tradition has become an integral part of their culture. Similarly, in Australia's Aboriginal communities, sleeping in groups is a long-standing custom, with community members arranging their beds in long rows for safety.
The arrangement of sleeping spaces also varies across cultures. In traditional Inuit culture, individuals are positioned to sleep facing east, towards the sunrise. In contrast, the Dutch historically used "bedstedes," built-in beds with doors that provided privacy and warmth during the winter. In modern times, some Swedish couples prefer separate duvets, allowing for individual temperature preferences and undisturbed sleep, which is said to promote a healthier relationship.
The timing of sleep also differs across cultures. In some African countries, such as Botswana and Zaire, traditional hunter-gatherer groups do not follow a fixed sleep schedule but rather sleep whenever they feel the need, be it during the day, evening, or night. This flexible approach to sleep may even contribute to better rest and reduced sleep anxiety, according to some experts.
Lastly, the use of blankets can have psychological and neurological implications. Weighted blankets, for instance, have been found to reduce anxiety and stress by increasing serotonin production, which is essential for sleep regulation. Additionally, the feeling of being covered or swaddled can provide a sense of security and comfort, reminiscent of being in the womb or childhood experiences of being tucked in by parents.
