Many people find it difficult to sleep without a blanket, even in hot weather. There are several reasons for this. Firstly, blankets help to regulate our body temperature, which is crucial for sleep. Our body temperature naturally drops at night, and blankets help to maintain this lower temperature, signalling to our body that it is time to sleep. Secondly, blankets provide a sense of comfort and security, which can reduce stress and anxiety, making it easier to fall asleep. Additionally, the weight of a blanket can stimulate the release of serotonin and dopamine, neurotransmitters that promote feelings of calm and well-being. Finally, sleeping with a blanket is often a long-standing habit, ingrained in us since childhood, and breaking this habit can be challenging.

Blankets help maintain body temperature, which is crucial for sleep
Our bodies are programmed to regulate our internal temperature, which helps us stay warm. However, during deep sleep, we lose this ability to thermoregulate, especially during the REM sleep cycle. This is when we seek help from external sources to keep us warm.
Our core body temperature starts to drop an hour or two before we go to bed and continues to fall throughout the night, reaching its lowest point at around 4 a.m. Blankets help us maintain our body temperature, preventing it from dropping too low and disrupting our sleep. They create a microclimate, a barrier that prevents the surrounding factors that cool our bodies from affecting us too much.
The use of blankets, especially weighted blankets, is associated with higher levels of serotonin, which is a neurotransmitter that encourages feelings of calm and happiness. The heaviness of the bedding may activate the parasympathetic nervous system, potentially increasing serotonin and dopamine levels. This helps explain why many people find it challenging to sleep without a blanket, even in hot weather.
To manage the heat while still enjoying the comfort of a blanket, you can opt for lighter, breathable fabrics such as flax, cotton, or bamboo. Cooling pads or blankets are also a great option to stay cool without sacrificing the sensory benefits of a thicker blanket.

They trigger feelings of safety and comfort, reducing stress and anxiety
The use of blankets, especially weighted ones, is associated with higher levels of serotonin, the neurotransmitter best known for encouraging feelings of calm. Sanam Hafeez, a neuropsychologist and adjunct professor at Columbia University, explains that during REM (rapid eye movement) sleep, our bodies drastically lower their levels of serotonin. This is when we lose our ability to thermoregulate and shiver, so we seek an external source of warmth.
The heaviness of a weighted blanket may cause deep pressure stimulation that activates the parasympathetic nervous system, potentially increasing serotonin and dopamine levels. Dopamine is another mood-boosting neurotransmitter. The warmth and comfort of a blanket can make us feel safe at night, triggering feelings of safety and comfort. This is especially true if we had a fear of the dark as children, which is a common fear that can persist into adulthood.
The use of blankets can be a key part of our bedtime rituals and circadian rhythm, or body clock. Our body temperature drops as we fall asleep, and blankets help us maintain the right temperature throughout the night. This is why many sleep experts recommend keeping the temperature of your room lower at night.
If you get hot at night but still want to use a blanket, consider keeping the room cooler and using lighter, breathable fabrics such as flax, cotton, or bamboo. You can also try using a cooling pad or blanket, or sleeping in your underwear.

Blankets are associated with higher serotonin levels, improving sleep quality
Many people experience difficulty sleeping without a blanket, even in hot weather. This phenomenon can be explained by the link between blankets and serotonin levels. Serotonin, often referred to as the "happy hormone," is a neurotransmitter that positively affects our mood, digestion, and sleep. During REM sleep, our bodies experience a decrease in serotonin levels, which is where blankets come into play.
Blankets, especially weighted ones, are associated with higher levels of serotonin. The deep pressure stimulation provided by weighted blankets activates the parasympathetic nervous system, leading to potential increases in serotonin and other mood-enhancing neurotransmitters like dopamine. This increase in serotonin contributes to improved sleep quality and a boost in overall happiness.
The use of blankets also helps regulate body temperature during sleep. Our circadian rhythm, which governs our sleep patterns, begins to lower our core body temperature in the afternoon and continues to do so throughout the night. Blankets prevent our body temperature from dropping too low, which can disrupt our sleep. This is especially important during REM sleep when our bodies lose the ability to thermoregulate.
To improve sleep quality, individuals who prefer sleeping with blankets can make adjustments to their bedding and sleep environment. Layering bedding allows for adjustments to be made as needed, and choosing lighter, breathable fabrics, such as flax, cotton, or bamboo, can help regulate temperature. Additionally, light-colored blankets absorb less heat, and cooling pads or blankets can be utilized to stay cool while still enjoying the sensory benefits of a blanket.
In summary, blankets, particularly weighted blankets, are associated with higher serotonin levels, which improve sleep quality and overall well-being. This increase in serotonin, along with temperature regulation, contributes to the widespread preference for sleeping with blankets, even in hot weather. By making thoughtful choices about bedding materials and layers, individuals can improve their sleep experience while still enjoying the comfort and security provided by blankets.

Circadian rhythm: body temperature drops before sleep, and blankets aid this process
Our bodies are governed by an internal 24-hour clock known as the circadian rhythm. This rhythm is responsible for regulating various bodily functions, including our sleep-wake cycle, hormone production, digestion, and body temperature. The circadian rhythm is influenced by both internal factors, such as our brain, and external factors, such as light exposure.
In the case of sleep, the circadian rhythm plays a crucial role in preparing our bodies for rest. As the day progresses towards evening, our core body temperature begins to drop gradually, starting as early as 2 p.m., according to sleep consultant Anna McGinn. This drop in temperature is a natural signal to our bodies that it's time to wind down and eventually fall asleep.
During the first few hours of sleep, our body temperature continues to decrease. However, during the REM (rapid eye movement) stage of sleep, our bodies lose their ability to thermoregulate, or control our temperature. This is where blankets come into play.
Blankets aid in maintaining our body temperature at an optimal level throughout the night. They provide a source of external warmth, especially during the REM stage when our bodies struggle to regulate temperature. This is particularly important in preventing our body temperature from dropping too low, which could interrupt our sleep. Additionally, blankets—especially weighted ones—are associated with increased levels of serotonin, a neurotransmitter that promotes feelings of calm and improves our sleep quality.
For those who tend to get hot at night but still crave the comfort of a blanket, there are a few strategies to consider. Firstly, maintaining a cooler room temperature between 19 and 23 degrees Celsius (66 to 73 degrees Fahrenheit) can help. Secondly, opting for lightweight, breathable fabrics for both bedding and sleepwear is recommended. Materials such as flax, cotton, or bamboo are ideal for keeping cool while still enjoying the sensation of being covered. Finally, utilizing a cooling pad or blanket, which are designed to provide a cozy experience without trapping heat, can be a great solution.

Habit: sleeping with blankets is ingrained, and their absence disrupts sleep routines
The habit of sleeping with blankets is deeply ingrained, and their absence can significantly disrupt sleep routines. This habit often stems from childhood, where we associate blankets with comfort, relaxation, and bedtime. The act of being “tucked in” becomes a cue for our brain that it's time to sleep. This association is so strong that even as adults, we continue to rely on blankets as a signal for sleep.
The use of blankets, especially during infancy, is a result of our bodies' limited ability to regulate temperature when we are young. Blankets help maintain our body temperature, ensuring we don't get too cold or too hot. This reliance on blankets for temperature regulation continues into adulthood, and our bodies are conditioned to expect this external help during sleep. Without blankets, our brains sense that something is missing, disrupting our sleep routines.
Additionally, the weight and pressure of blankets have been linked to increased serotonin levels, contributing to feelings of calm and happiness. Serotonin also aids in the production of melatonin, a natural sleep hormone. Therefore, blankets not only provide physical comfort but also positively impact our brain chemistry, further reinforcing the habit of sleeping with them.
Breaking the habit of sleeping with blankets can be challenging. However, it is possible to make adjustments to improve sleep quality during hot weather. Experts recommend using lightweight, breathable bedding made from materials like cotton or wool, which can help regulate temperature. Gradually transitioning from thicker to lighter blankets as the seasons change can also help your body adjust to the weight and temperature differences.
While it is a challenging habit to break, sleeping without blankets in hot weather is possible by making gradual adjustments to bedding materials and thickness, ultimately improving sleep quality.
