Humans need covers to sleep because they help maintain core body temperature during sleep. During REM sleep, the body can't regulate its own temperature, so covers are needed to prevent the body from getting too cold. Covers also provide comfort, which ensures the necessary sleep duration. Weighted blankets have been found to decrease anxiety and stress, as gentle pressure can stimulate serotonin production.

What You'll Learn
Humans need covers to maintain core body temperature during sleep
REM sleep, which occurs around dawn when temperatures are coldest, is when the body cannot regulate its own temperature. Therefore, we need blankets to prevent us from waking up shivering.
Blankets create a 'microclimate' around the skin, trapping heat that escapes from the body at night and keeping the body warm. This means that the physical sensation of being under a blanket is associated with sleep.
Weighted blankets have also been found to decrease anxiety and stress, as gentle pressure can stimulate serotonin production.

Covers promote overall sleep quality by providing comfort
Weighted blankets have been found to decrease anxiety and stress, as gentle pressure can stimulate serotonin production. 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.
Human characteristics such as our circadian rhythm, the production of serotonin and melatonin, and maintaining core body temperature during sleep all depend on blankets or some form of body covering.

Covers are needed to prevent waking up from being too cold
Humans need covers to sleep to prevent waking up from being too cold. During an 8 to 9-hour sleep period, the body's temperature will decrease in tiny increments for around 5 to 6 hours. During REM sleep, the body cannot regulate its own temperature, so it is important to have some form of covering to maintain core body temperature.
Weighted blankets can also decrease anxiety and stress, as gentle pressure can stimulate serotonin production.
The physical sensation of a blanket can also prime the brain and body for sleep. Michael Grandner, PhD, director of the Sleep and Health Research Program at the University of Arizona in Tucson, says that a blanket creates a 'microclimate' around the skin that is usually warmer than the surrounding environment.

Covers can help to stimulate serotonin production
Humans need covers to sleep because they help maintain core body temperature during sleep. Covers can also help stimulate serotonin production, which is important for regulating mood, sleep, and other bodily functions.
During REM sleep, the body cannot regulate its own temperature, and people tend to be in the REM stage of sleep around dawn, when temperatures are coldest. Covers help to trap heat that escapes from the body, keeping the body warm. This trapped heat also creates a 'microclimate' around the skin, which is usually warmer than the surrounding environment.
Weighted blankets have been found to decrease anxiety and stress, as gentle pressure can stimulate serotonin production. This increase in serotonin can help improve sleep quality and duration.
Additionally, the physical sensation of being under a blanket can cause the brain and body to be primed for sleep. The body associates the feeling of being under a blanket with sleep, as most people sleep with a blanket. Therefore, simply being under a blanket can trigger the brain and body to prepare for sleep, improving sleep quality.

Humans have been conditioned to use covers since birth
As we grow older, we continue to associate covers with sleep. The physical sensation of being under a blanket becomes linked with sleep in our brains. This means that simply pulling up a duvet or wrapping ourselves in a blanket can trigger our brains and bodies to prepare for sleep.
Additionally, covers play a crucial role in maintaining our core body temperature while we sleep. During the night, our body temperature naturally decreases, and we enter the REM stage of sleep, during which our bodies struggle to regulate their temperature. Covers help trap our body heat, preventing us from getting too cold and waking up shivering.
While some argue that the need for covers is cultural, with humans adapting if they slept outside, the fact remains that for most people, sleeping with covers is a deeply ingrained habit. It is a behaviour that has been reinforced since infancy, and for many, the idea of sleeping without covers is uncomfortable and disruptive to their sleep quality.

If you don't use covers, you may wake up because you're too cold. This is especially true during the REM stage of sleep, which usually occurs around dawn when temperatures are coldest.
Yes, weighted blankets have been found to decrease anxiety and stress by stimulating serotonin production.
Yes, we've been conditioned to use blankets since birth, so the physical sensation of being under a blanket is often associated with sleep.
