This type of mattress topper is a good potential option for those who find they get hot and sweaty at night but cannot invest in a new mattress.

What Is A Cooling Mattress Topper

Mattress toppers are an additional layer of bedding placed on top of your mattress that have the potential to in some way alter your sleep surface. Like a cooling mattress, a topper designed specifically for cooling purposes should offer something in terms of construction and materials to help ensure a cool and comfortable sleep. A cooling mattress topper is a good potential option for those who find they get hot and sweaty at night but cannot invest in a new mattress.

Temperature And Sleep

Sleep deprivation can be debilitating and compromise our quality of life, and an appropriate sleep environment is critical to achieving adequate quality and quantity of sleep. Many factors affect sleep, and temperature plays an integral role.

Temperature and sleep

Research✓ shows that in addition to falling asleep and sleep duration, temperature has a significant effect on sleep calmness and even appetite. Both our sleep environment and body temperature can influence our sleep experience. A review✓ of the environmental parameters required for an ideal sleep environment shows optimal ambient temperature between 17 and 28 °C (depending on humidity). Furthermore, a decline in core body temperature has been shown✓ to increase the likelihood of falling asleep and may facilitate a deeper sleep.

Fun fact!
The release of "sleep hormone" melatonin induces changes✓ that result in a drop of our body temperature about 2 hours before sleep, essentially preparing our body for optimal sleep.

Causes Of Overheating When We Sleep

There are many different reasons why people may wake up hot and sweaty during the night. Causes of "night sweats"✓ may include menopause symptoms (“hot flushes”), anxiety, medicines, low blood sugar, alcohol or drug use, or hyperhidrosis (a harmless condition where you sweat a lot). Many people tend to be “hot sleepers” without any underlying pathologies or apparent reasons. Causes of “night sweats” in some individuals are unexplained.

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 bedding designed for hot sleepers. A cooling mattress topper may potentially be a way to offer hot sleepers a cool, comfortable, restful sleep. If you have any concerns that your overheating is due to any medical issues, it is advisable to see a doctor.

Interesting to note...
There is a growing body of literature✓ demonstrating how climate change may disrupt human sleep.

Cooling Mattress Toppers: Considerations

There are some factors to consider when buying a cooling mattress topper. Therefore, it is essential to be clear on your personal needs and preferences and well-informed about your options to make the best decision.

Cooling mattress topper considerations
  • Cooling properties: Using materials that naturally promote airflow and don’t retain heat may seem like the only way to accomplish a cool sleep surface. However, manufacturers can also use clever aerated design, technologies, or specific infusions or layers to draw heat away from the body.
  • Price: As with all bedding, the price will be largely determined by the materials and quality. The pricier toppers are more likely to be made of higher quality materials, use more advanced technologies, and have a longer lifespan. Alternatively, cheaper mattress toppers may sometimes tend to have a shorter lifespan.
  • Sleeping position: Different sleep positions usually require pressure relief at different points. In general, side sleepers require a slightly thicker, softer mattress topper that reduces pressure in the hips and shoulders, back sleepers need a more mid-range firmness, sometimes needing relief in the hips, and stomach sleepers often a firmer thinner, topper.
  • Firmness level: The firmness of a sleep surface is a critical factor in temperature regulation, as a softer surface will allow a sleeper to sink in further, resulting in more heat build-up around the sleeper. Heavy people may sink in further than lighter people, leading to an increase in heat retention, so therefore a firmer mattress topper may be a better option.
  • Thickness: Mattress toppers are usually a 3cm -10cm thick addition to your mattress, and sleepers who exert more pressure on a sleep surface, like side sleepers or heavier individuals, may be better suited to a thicker mattress topper.

Types Of Mattress Toppers For Cooling

“Cooling” products have been trendy in the bedding industry. Between the constant advancement of technologies and materials and the clever marketing terms, it’s understandable that one can become overwhelmed. Each material has its advantages and disadvantages. Hopefully, this section will give you a clearer understanding of what cooling topper types are on the market today and which is best suited for you as a hot sleeper.

Types of mattress toppers for cooling

Memory Foam

Memory foam toppers (often called viscoelastic) are 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. Traditional memory foam, however, is known to trap heat due to the density of the material. Another possible choice could be a cooling infused memory foam mattress topper which can help to cool you down. Some of these toppers use gel and other materials like graphite, copper, or charcoal to draw heat away from the sleeper.

Polyfoam

Polyfoam is similar to memory foam as they both contain polyurethane (an umbrella term used to describe a synthetic blend of organic compounds), a product of the petroleum industry. However, polyfoam differs from memory foam as it is generally less dense and does not retain as much heat. Open-cell polyfoam is designed to improve the breathability of the topper, thereby facilitating thermoregulation. Polyfoam is often the cheapest topper material but is not known for being durable or eco-friendly. It may also develop permanent body indentations over time.

Latex

Latex mattress toppers can be made from natural and synthetic materials. Natural latex is harvested from the sap of rubber trees, and synthetic latex is a petroleum chemical-based “man-made” version of natural latexBlended latex is a combination of both. Due to its inherently elastic properties, latex can contour to your body shape, allow for pressure relief as well as provide support. Latex is an excellent choice for cooling as it’s known to be a temperature regulating material and can increase airflow; body heat is dispersed, keeping the sleeper cool. Latex is known for its durability and sustainability, although it can also be on the pricier side. They are also sometimes constructed with ventilation holes that further facilitate air circulation and temperature regulation.

Hot Sleepers: Tips To Keep Cool

In addition to trying out a cooling mattress topper, listed below are a few useful tips that can contribute to a cool, comfortable sleep.

Hot sleepers tips to keep cool
