A cooling mattress pad aims to help prevent overheating and ensure a cool, restful night’s sleep.

A drop in the body’s temperature is important for getting to sleep, and being too hot may disrupt sleep patterns and reduce sleep quality.

A person can take various steps to keep the bedroom cool, including investing in cooling bedding.

This article describes the possible benefits of a cooling mattress pad, how these pads work, and some of the best options available.

A quick look at 7 of the best cooling mattress pads

A person’s body temperature typically lowers during sleep. High temperatures can negatively affect the quality and natural patterns of sleep.

A 2019 study into the effects of hot weather on sleep found that sleep quality was best at around 89.6°F and worst at around 98.6°F. High temperatures negatively impacted participants’ ability to fall asleep, their sleep satisfaction, and the adequacy of their sleep.

A 2017 study found that rising nighttime temperatures in the United States may prevent adequate sleep, particularly for older adults and lower-income people.

A mattress can be a significant investment and finding one that suits each sleeper’s needs can take time. Meanwhile, sleep habits and needs can change over time, and a mattress’s support and cooling capability can gradually reduce.

A mattress pad can be an affordable way to add cooling or comfort to a bed without replacing the mattress.

Having a mattress pad can also prolong the lifespan of the mattress.

Additionally, a person may wish to invest in a cooling mattress. Learn more about the top cooling mattresses.

A cooling mattress pad helps the body maintain a regular temperature throughout the night. It does so actively or passively.

A passive pad works because of the materials it contains. These may include:

  • gel-infused memory foam
  • cooling gel beads
  • natural latex from rubber trees
  • phase change material, which absorbs or releases heat depending on the environment
  • moisture-wicking fabrics, such as those common in sports and fitness clothing

An active cooling mattress pad uses additional devices, such as water pumps or an attachable fan. They tend to be more expensive and complex.

Those looking for mattress cooling pads may want to consider the below criteria before making a decision:

  • Materials: Some people may prefer certain materials, such as cotton, because they are breathable, soft, and can be washed easily. However, foam mattress pads may offer more cushioning and support than fiber fillings. A person should consider the comfort levels they would like from their mattress pad and any allergies they have to natural or synthetic materials.
  • Warranty and trial period: Many brands offer trial periods and return windows so that a person can try their chosen mattress pad and send it back to the company if it is not right. A person should check the returns and warranty policies before making a purchase.
  • Certifications: Some products have environmental or manufacturing certifications that state the company adheres to textiles standards or uses sustainable or environmentally friendly manufacturing processes.
  • Cost: A person should consider the features they need in a mattress pad and how that will fit their budget. Prices can vary greatly with mattress pads, with some costing under $50 and others costing over $1,000.

Below are some of the most commonly asked questions about cooling mattress pads.

Do you put a sheet over a cooling mattress pad?

People can put a sheet over the cooling mattress pad to protect it from wear and stains. However, it is not mandatory unless the manufacturer states it is. Some pads come with a plush cover or layer that mimics a blanket feel, eliminating the need to cover it with sheets.

Are cooling mattress toppers worth it?

How effective a person finds a cooling mattress topper depends on various factors. For example, those living in hot climates may not find cooling mattress toppers powerful enough. However, cooling mattress toppers or pads can be a cheaper solution than using air conditioning for those who would like to reduce their sleep temperature.

How do you clean a cooling mattress pad?

Many cooling mattress pads come with instructions stating they should be machine washed cold without harsh detergents and tumble dried on a low, no heat setting. However, a person should always follow the instructions that come with the product to avoid damaging it. If a person opts for a cooling mattress pad that connects to an electrical cooling machine, they should follow instructions closely, ensuring the product is washed and dried safely.

People who wake up feeling hot at night or feel the heat is affecting their sleep quality may benefit from a cooling mattress pad.

This type of product may contain thermoregulating materials or come with fans or other cooling technology.

A cooling pad or topper may also increase a mattress’s comfort, support, and longevity.
