There are several reasons why people sleep under blankets. One reason is that blankets provide warmth, even on summer nights when temperatures drop after dawn. Additionally, blankets create a microclimate around the skin, which is usually warmer than the surrounding environment. From a behavioural perspective, people may sleep under blankets due to conditioning since childhood. Sleeping under blankets may also trigger the release of oxytocin, the cuddle hormone, which makes us feel warm, safe, and bonded. Furthermore, weighted blankets are known to help people with insomnia and anxiety, as they provide a sense of security and comfort.

Weighted blankets can help with insomnia and anxiety
The use of weighted blankets to aid sleep and alleviate insomnia and anxiety has become increasingly popular. While there is limited scientific evidence to support their effectiveness, many people swear by them, and sales have surged in recent years.
Weighted blankets are typically filled with plastic beads or pellets to make them heavier, with weights ranging from 3 to 20 pounds or more. The weight of the blanket provides deep pressure stimulation, a therapeutic technique that relaxes the nervous system. This pressure can trigger nervous system responses that lower heart rate and slow breathing, helping to calm anxiety and improve sleep. The weight may also trigger the release of serotonin, which aids sleep and stabilizes mood, and oxytocin, which can reduce pain and stress.
The use of weighted blankets has been studied in various contexts, with some positive results. One study found that college students who slept under weighted blankets for one semester experienced lower anxiety and better sleep quality. Another study of adults receiving chemotherapy found that weighted blankets reduced their anxiety during the procedure. Additionally, a 2021 study of 94 participants found that weighted blankets were associated with reduced perceptions of chronic pain, particularly in those with anxiety.
However, it is important to note that weighted blankets may not work for everyone. While generally low-risk, they may not be suitable for everyone, especially children under two years old, due to the potential risk of suffocation. Other evidence-based solutions for insomnia, such as cognitive-behavioral therapy (CBT) and relaxation techniques, should also be considered.
Ultimately, the decision to use a weighted blanket is a personal one. While they may not be a miracle cure, many people find them helpful for improving sleep and reducing anxiety.

Blankets can make us feel safe and secure
The use of blankets while sleeping is a common practice, and science provides insights into why this habit contributes to a sense of safety and security. Firstly, blankets create a microclimate around the skin, providing warmth and comfort. This warmth is associated with the feeling of being tucked in, which activates the body's parasympathetic nervous system, leading to a lowered heart rate, reduced tension, and enhanced relaxation. The weight and warmth of blankets can also reduce anxiety and promote a sense of calmness, as supported by research from Flinders University and the University of Adelaide in Australia.
Additionally, the use of blankets can be linked to "pure conditioning." From infancy, we are accustomed to sleeping with blankets, and this association between blankets and sleep persists into adulthood. Dr. Alice Hoagland, the director of the insomnia clinic at the Unity Sleep Disorder Center in Rochester, New York, explains that this is a form of transitional object, akin to Pavlovian conditioning. The blanket becomes a source of familiarity and security, reminding us of the comfort we experienced as children.
The physiological aspect of blanket usage is also noteworthy. Our body temperature begins to drop about an hour before our usual bedtime, and this decrease in core temperature makes us feel sleepier. Blankets help maintain a comfortable microclimate, ensuring that we don't get too cold during sleep. This temperature regulation is especially crucial during the REM sleep cycle when our bodies lose the ability to regulate temperature effectively.
The weight of blankets also plays a role in providing a sense of safety and security. Weighted blankets, in particular, have been found to promote calmer sleep and are recommended for individuals with anxiety or insomnia. The gentle, consistent pressure they provide can ease chronic pain and improve overall sleep quality. However, it's important to remember that the benefits of weighted blankets may vary from person to person, and they should be used with consideration for individual preferences and comfort levels.
In conclusion, blankets offer a sense of safety and security by creating a comfortable microclimate, evoking conditioned feelings of relaxation, and providing physiological benefits through temperature regulation and anxiety reduction. The weight of blankets, especially weighted blankets, can further enhance these effects, promoting calmer and more restful sleep.

They trigger a relaxation response in our bodies
The use of blankets while sleeping is a nearly universal habit. Even in hot climates, people tend to sleep under a blanket. This behaviour can be attributed to both physiological and psychological factors.
Physiologically, our bodies begin to lose core temperature about an hour before our usual bedtime. The body's internal temperature is physiologically linked to our alertness. When the body is heated, we feel more alert, and when it cools down, we tend to feel sleepier. Cooler internal body temperatures are correlated with a rise in melatonin, a hormone that induces sleepiness.
Psychologically, blankets can trigger a relaxation response in our bodies. Our brains interpret the physical "holding" of a blanket as a sign of safety, activating the parasympathetic nervous system, which regulates heart rate and promotes calmness and relaxation. This effect is enhanced by weighted blankets, which provide even pressure across the body, helping to release serotonin, a mood and sleep regulator. The weight of the blanket can also reduce anxiety and promote relaxation.
The use of blankets can also be attributed to conditioning. We are often conditioned from birth to associate blankets with sleep. This association is reinforced by the warm, enclosed feeling that blankets provide, which may simulate the comfort and security of the womb.
Additionally, blankets can create physical boundaries around our personal space, providing a sense of protection and escape from the outside world. This may tap into our primal instincts for safety and shelter.
Overall, the use of blankets while sleeping is influenced by a combination of physiological and psychological factors, including the relaxation response triggered by the pressure and warmth of the blanket.

Blankets help regulate body temperature
Using a blanket while sleeping is not just a habit, but it also offers key health benefits. Our bodies tend to lose core temperature about 60 to 90 minutes before our usual bedtime. This cooling down of the body makes us feel sleepier. Our body temperature continues to drop while we sleep, eventually reaching one or two degrees below our average body temperature.
During the REM sleep cycle, our bodies lose the ability to regulate temperature. This is where blankets come to our rescue, helping us maintain a comfortable body temperature. Blankets create a 'microclimate' around our skin, which is usually warmer than the surrounding environment.
Weighted blankets have been found to be especially beneficial for people with insomnia and anxiety. A study published in the Journal of Sleep Medicine & Disorders in 2015 found that sleeping under a weighted blanket helped people with insomnia have a calmer night's sleep. Similarly, a review of research published in the American Journal of Occupational Therapy in 2020 suggested that weighted blankets may benefit people with anxiety.
The urge to sleep under a blanket, even during hot summer nights, may be rooted in psychology and biology. The snug feeling of being tucked in activates the body's parasympathetic nervous system, which lowers the heart rate, eases tension, and helps us relax. Research has also linked blanket use to potential mental health benefits in adults, including reduced anxiety and symptoms of depression.
Thus, blankets play a crucial role in regulating our body temperature during sleep, and they also provide additional psychological and physiological benefits.

They are a form of 'pure conditioning'
The use of blankets while sleeping is a common practice, and there are several reasons why people might find comfort in sleeping under a blanket. One theory suggests that this behaviour is a form of pure conditioning.
Dr. Alice Hoagland, the director of the insomnia clinic at the Unity Sleep Disorder Center in Rochester, New York, explains that the tendency to sleep under a blanket has two components: a behavioural and a physiological aspect. The behavioural element, or "pure conditioning" as Hoagland refers to it, plays a significant role in our attachment to blankets. From birth, we are conditioned to associate blankets with sleep. This is similar to Pavlov's classical conditioning experiment, where a stimulus (the sound of a bell) consistently paired with food caused dogs to salivate at the sound alone. Similarly, we have been conditioned to associate blankets with falling asleep.
The use of blankets from a young age is deeply rooted in our upbringing. Well-meaning adults often provide babies with blankets as they are less effective at regulating their body temperature and are more susceptible to the cold. As a result, we develop a strong association between blankets and sleep, to the extent that even the thought of sleeping without a blanket can be uncomfortable for some. This conditioning is so powerful that simply pulling up a blanket can trigger a sense of sleepiness, even if the room is warm.
Additionally, blankets can serve as transitional objects, providing a sense of security and comfort. They create a "microclimate" around our skin, typically warmer than the surrounding environment, which enhances our feeling of comfort. This warmth and enclosure may remind us of the womb, further contributing to our sense of security. The weight and warmth of a blanket can also reduce anxiety and promote relaxation, making it easier to fall asleep.
The act of curling up under a blanket triggers the release of oxytocin, often referred to as the "cuddle hormone." Oxytocin makes us feel warm, safe, and bonded. Blankets also activate our parasympathetic nervous system, helping to regulate our heart rate and induce a sense of calmness and relaxation.
In summary, the use of blankets while sleeping is indeed influenced by pure conditioning. This conditioning starts from birth and shapes our association between blankets and sleep throughout our lives. The comfort, security, and physiological changes induced by blankets all contribute to their effectiveness as a sleep aid.
