Humans have a strong affinity for sleeping under blankets, even in hot climates. This phenomenon can be attributed to various biological, neurological, and psychological factors. From a biological standpoint, our body temperatures naturally drop during sleep, and blankets help us maintain warmth, especially during the REM stage when our bodies struggle to regulate temperature. Blankets also increase serotonin and melatonin levels, promoting relaxation and aiding in falling asleep. Neurologically, weighted blankets stimulate serotonin production, reducing anxiety and improving sleep regulation. Psychologically, we associate blankets with comfort and security, a connection established since childhood when swaddled as infants. Additionally, blankets act as a physical barrier, shielding us from disturbances like a gentle breeze, and creating a microclimate that buffers against ambient temperature changes.

Weighted blankets can reduce anxiety and improve sleep
The use of weighted blankets has been linked to reduced anxiety and improved sleep quality in several studies. The gentle full-body pressure of a weighted blanket creates a hug-like sensation, harnessing the therapeutic power of deep touch pressure (DTP). This stimulation lowers cortisol levels, increases serotonin and melatonin production, and helps the body relax.
A 2020 study found that weighted blankets may improve sleep and reduce daytime fatigue, depression, and anxiety in people with major depressive disorder and bipolar disorder. Another study of 26 children with ADHD and sleep difficulties found that using weighted blankets helped calm their heart rate and breathing, making it easier to relax before sleep.
Weighted blankets have also been found to be beneficial for children and adults with autism or ADHD, helping them cope with symptoms of sensory overload and hyperactivity. A randomized controlled study in Stockholm, Sweden, found that weighted chain blankets were a safe and effective intervention for insomnia in adult patients with ADHD, improving their daytime symptoms and activity levels.
The use of weighted blankets has also been shown to reduce anxiety in cancer patients undergoing chemotherapy and medical procedures. A controlled clinical trial found that cancer patients using weighted blankets for 30 minutes experienced significantly lower anxiety levels than those receiving standard care. Similarly, a follow-up study on adolescents undergoing a tooth-pulling procedure found that the use of a weighted blanket helped reduce anxiety during the procedure.
Overall, weighted blankets provide a natural, drug-free method to improve sleep and reduce anxiety, offering a cozy addition to one's sleeping routine or a medical necessity for those with chronic conditions.

Blankets aid in thermoregulation and increase melatonin
The human body's core temperature varies over a 24-hour period, with the body losing heat during sleep. Lowering the body's shell temperature by 0.4°C can lead to significant decreases in early waking and more time spent in deep sleep. Blankets aid in this thermoregulation by creating a microclimate that varies less significantly with ambient temperature changes.
The body's core temperature begins to drop around 2 p.m., continuing to drop throughout the evening, and reaching one or two degrees below average during REM sleep, when the body loses its ability to regulate temperature. This nightly cool-down is a key part of the circadian rhythm that determines when the body is ready to sleep and wake. Blankets help us deal with these lower nightly core body temperatures, making us more comfortable and relaxed.
Weighted blankets have been found to decrease anxiety and stress by stimulating serotonin production, which helps modulate sleep regulation. They have also been found to increase melatonin levels in the brain, which helps us relax and fall asleep. The gentle pressure of weighted blankets can also relax the nervous system, making it easier to have a more restful sleep.

They create a microclimate, reducing the impact of ambient temperature changes
The human body's core temperature varies over a 24-hour period, with the body losing heat during normal sleeping hours. Our body temperatures begin to cool down before we go to bed, reaching one or two degrees below our average body temperature. Once we reach the REM sleep cycle, our body loses its ability to regulate its temperature.
A blanket creates a microclimate around the skin, which is usually warmer than the surrounding environment, reducing the impact of ambient temperature changes. This microclimate varies less significantly with ambient temperature changes, protecting us from the breeze from a window or vents in the house, which can cool exposed skin and disrupt sleep.
Sleep consultant Alanna McGinn notes that using a blanket helps us deal with our lower nightly core body temperatures. She adds that blankets increase serotonin and melatonin levels in our brains, which help relax us and fall asleep.
Even in warmer climates, people still use blankets when they sleep, even if it's just a light sheet. Our core body temperature tends to drop when we fall asleep, and this drop in temperature continues through the night, making us feel too cold. That's when a blanket can help warm us up.
Therefore, blankets help us sleep better by creating a microclimate that reduces the impact of ambient temperature changes, ensuring that we remain warm and comfortable throughout the night.

Blankets are a physical barrier, protecting from drafts and insects
The use of blankets while sleeping is a common practice, even in warmer climates. Blankets provide a physical barrier that protects us from drafts and insects, ensuring a comfortable and peaceful sleep.
Blankets act as a protective shield, creating a microclimate around our bodies that shields us from drafts and sudden temperature changes. This microclimate helps maintain a consistent temperature, promoting a deeper and more restful sleep. The barrier formed by blankets prevents cool drafts from reaching our skin, keeping us warm and cozy throughout the night.
Additionally, blankets offer protection from insects and other small creatures that may disturb our sleep. They act as a physical barrier, preventing insects from reaching our skin and providing a sense of security and comfort. This barrier effect is especially beneficial for those who enjoy sleeping with open windows or in areas with insect infestations.
The presence of a blanket also provides a sense of security and comfort, reminiscent of being swaddled as a baby. This psychological association can help reduce anxiety and promote a calmer state of mind, further enhancing the quality of sleep.
Furthermore, blankets have been found to improve sleep quality by increasing serotonin and melatonin levels in the brain. The gentle pressure provided by weighted blankets stimulates serotonin production, which helps regulate sleep and improves overall relaxation.
In summary, blankets offer a physical barrier that protects us from drafts and insects, maintains a comfortable microclimate, and provides a sense of security and relaxation, all of which contribute to a better night's sleep.
