Many factors contribute to the quality of our sleep, and one of the most common complaints from sleepers is that they get too hot. "Hot sleepers" may experience this discomfort for many reasons, and the addition of specialised bedding for cooling purposes may help to eliminate or at least minimise the problem.

What Is A Cooling Pillow
The term “cooling pillow” refers to any pillow that prevents heat retention and provides a cool or neutral temperature sleep surface. Cooling pillows are designed and constructed to facilitate increased airflow, prevent heat retention, and encourage heat to be drawn away from the body. They may be made from different materials, such as gel-infused memory foam or latex. In addition, the pillow cover materials are often breathable and moisture-wicking.
Why We Sweat
We all know what sweat is but perhaps haven’t thought about why it happens and how it helps to cool us. Our body core temperature✓ is usually around 37 degrees celsius. When our body temperature starts rising, a small region in our brain (the hypothalamus) sends a message to our eccrine sweat glands, which are distributed all over the body, to start producing sweat to cool us down. Our bodies then use energy in the form of heat to remove the sweat from our skin - evaporation. As our excess body heat is used to convert beads of sweat into vapour, the skin’s surface cools. Sweating thus helps to regulate body temperature.
Why Sleeping Cool Is Important
It is well understood that sleep deprivation can be debilitating and compromise our quality of life. An appropriate sleep environment is critical to achieving adequate quality and quantity of sleep. Many factors affect sleep, and temperature plays an integral role✓.
- A decline in core body temperature has been shown✓ to increase the likelihood of falling asleep and may facilitate a deeper sleep and sleep duration.
- People generally tend to sleep better in a cool environment✓ and the best room temperature is said to be between 15.6 to 19.4 degrees Celsius.
We usually experience a drop in body temperature✓ while sleeping; however, some people “sleep hot” without any underlying pathologies or apparent reasons.
Causes Of Night Sweating
It is well documented that night sweats can be a symptom of menopause, autoimmune diseases, malignancies, and infections; however, many people without these conditions experience overheating at night. Research✓ shows that questions about night sweats to be among the most frequent questions asked by patients, yet any evidence-based explanations are still lacking.
A systematic review✓ focusing on night sweats concluded that the cause and management of night sweats remain largely unexplained. However, certain things that were shown to make people sweat at night include blood pressure medications, antidepressants, alcohol, or eating too close to bed. These things can disrupt temperature control mechanisms.
Regardless of the reason, some bedding may help alleviate these night sweats, and some may exacerbate them. The best way to maintain your bed at the right temperature is to choose appropriate bedding. A cooling mattress, cooling mattress topper, or cooling pillow may potentially be a way to offer hot sleepers a cool, comfortable, restful sleep. It is worth noting that if you have any concerns that your overheating is due to any medical issues, it is advisable to see a doctor.
Cooling Pillows: Considerations
A cooling pillow should draw heat away from the body, and certain materials can do this better than others. In addition to cooling properties, your pillow should also offer the optimal comfort and support for your head and neck. Therefore, it is essential to be clear on your personal needs and preferences and well-informed about your options to make the most well-informed decision.
- Cooling properties: Cooling pillows are constructed with materials that naturally promote airflow, actively draw heat away from the body, and do not retain heat. Natural materials such as cotton are naturally breathable and prevent heat retention. In addition, gel, copper and graphite are materials that can draw heat away from the body and dissipate it.
- Sleeping position: Different sleep positions usually require a pillow with different firmness and loft (height). Side sleepers usually need a softer pillow with a higher loft that fills the space between the neck and shoulders. Stomach sleepers generally prefer a firmer, thinner pillow that doesn’t lift the head too much, and back sleepers need somewhere in the middle.
- Firmness level: Cooling pillows commonly have a medium-soft to medium-firm feel. The softer pillows may be composed of down, or shredded memory foam and the firmer pillows are often made of solid foam or latex.
- Pressure relief: The correct pillow should provide optimal support, comfort and pressure relief in the neck and shoulders. It should contour to the head and ensure correct spinal alignment.
- Loft: Loft refers to the height of the pillow, and the choice of loft will depend on your sleeping position as well as personal preference. Some cooling pillows have an adjustable loft, which may be useful if you want to remove or add filling to change the height of the pillow.
- Price: As with all bedding, the price will be largely determined by the materials and quality. The more expensive pillows are more likely to be made of higher quality materials, use more advanced technologies, and have a longer lifespan.
- Trial period: Some manufacturers offer a trial period with the pillow - this may be useful for those who are not sure of their needs and what will suit them best. Be sure always to read the fine print.
Cooling Pillow Fill Materials
The type of pillow fill often comes down to individual needs and personal preferences. Certain materials have specific qualities that can offer you optimal cooling, as well as other benefits.
Natural latex is harvested from the sap of rubber trees and is known for being soft and supportive. It is biodegradable, flame resistant, quiet, and resistant to mould, mildew and dust mites. In addition, this material is durable and helps with temperature regulation making a latex pillow a good potential choice for hot sleepers.
Memory foam (often called viscoelastic) is made using polyurethane material that is sensitive to body heat and allows it to contour to your body, providing pressure relief, comfort and motion isolation. However, traditional memory foam is known to trap heat due to the density of the material, so be sure to look for an open-cell memory foam pillow or one infused with gel or copper to draw heat away from the body.
Gel particles or beads can be added to other fill materials (generally foam) and can pull heat away from the body, maintaining a cool surface, thereby facilitating temperature regulation. These gel-infused foams are, however, often on the more pricey side.
Down alternative is a synthetic form of traditional down, made with the down feathers of ducks or geese. It is usually constructed with a polyester microfibre, and the material mimics the soft plushness of a goose down pillow. Down alternative is less likely to retain heat than down and is also usually more affordable.
Sweating: Interesting Facts
As we know, sweating is a bodily function that aids in temperature regulation. Below are a few things about sweating you may find interesting:
- Humans have up to 4 million sweat glands✓ distributed all over the body (roughly 3 million eccrine and 1 million apocrine).
- The highest sweat gland densities✓ are on the palms and soles and respond to emotional as well as thermal stimuli.
- The eccrine glands are functional early in life✓ - starting at roughly 2 to 3 years of age.
- The total number of eccrine glands is fixed throughout life✓.
- The amount of sweating between individuals varies not because some people have more sweat glands than others but rather due to differences in sweat secretion rate per gland✓.
