Hot Mattress Solutions: How to Cool Your Mattress

Memory Foam Mattress Sweating

Increase Airflow Below the Mattress

Most memory foam mattresses are made from viscoelastic, a soft and absorbent material. It’s designed to mold to your body and evenly distribute body weight in response to heat and pressure, which relieves pain and creates pressure points. To work accurately, memory foam mattresses use the heat coming off of you. The denser the foam material, the higher the heat you’ll feel.

Increasing the airflow under your mattress and bed can make a foam mattress cooler. Air trapped under your mattress increases your body heat and keeps it up, increasing your discomfort. Replace the solid wood or plywood under your bed with equally spaced slats, or exchange your bed frame for one that allows airflow. 

Use Cotton or Bamboo Sheets 

Sheets made from synthetic materials like polyester easily trap heat and are not as breathable. Bamboo or cotton sheets eliminate the moisture that makes you sweat. Bamboo is also a natural, moisture-wicking material that regulates body temperature and cools you down while you sleep. 

Wool bedding like duvets, sheets, and pillowcases absorb moisture from your body and control the mattress’s temperature, making you feel less hot and clammy. Thick covers reduce the skin’s surface area, making it harder to cool down. Also, they don’t let out as much moisture and air.

Get a Firmer Bed

It’s no secret soft beds are comfortable to sleep on. But because they reduce the surface area your skin uses to cool off, you heat up faster and sweat more. As comfortable as it is to sink into a soft bed, you also retain more heat. 

A firmer bed keeps you cooler for longer because it exposes more body surface area to the air. A firmer mattress provides your bed and body with more opportunity for ventilation.

Stop Exercising before bed

Exercising before bed can mess up your body temperature’s homeostasis, making it harder to cool down. After working out, it can take hours for your body temperature to stabilize. Only exercise in the evenings if you cannot help it. Otherwise, work out right after work or in the mornings.

Avoid Eating Too Late or Consuming Spicy Foods

The digestion process uses a lot of energy. When you consume spicy food or have a late meal, it makes your body work overtime. Much of the heat your body generates is from the organs. Eating earlier or consuming less spicy food helps your body wind down earlier, reducing heat. 

Memory Foam Mattress Sweating, What To Do?

Hot Mattress Solutions: How to Cool Your Mattress

Memory foam mattresses offer an incredible amount of comfort. They provide great relief to people who suffer from back or neck pain and those who sleep poorly. Their unique, airy internal structure perfectly adapts to body contours. 

But they tend to be hot and sweaty because their porous nature has tiny bubbly spaces that trap heat inside the foam. Your body weight compresses these bubbles, eliminating space for air to circulate. To counter the heat generated by a foam mattress: 

  • Get a breathable mattress protector. Wool and cotton are natural, breathable, and extremely effective materials for keeping your body cool. Moreover, mattress protectors are easy to clean, keep odors and stains away.
  • Use cooling pads and toppers. They are lightweight, affordable, and an easy way to cool your bed. They slide over your mattress like bedding. Mattress toppers made from natural cotton, gel foam, or down alternative add a layer of space that encourages better airflow, cooling you down.

My Mattress Protector Makes Me Sweat, What Should I Do?

While not all mattress protectors can make you sweat, depending on the fabric quality, some will. A waterproof vinyl mattress pad increases sweating because it prevents air circulation. It traps hot air, making it difficult to regulate body temperature. To prevent the sweating caused by a mattress protector:

  • Use natural, breathable mattress protectors. Cotton, wool, or bamboo materials draw moisture away and increase air circulation. Natural latex also has excellent airflow and heat exchange.
  • Switch to a bed pad. Bed pads offer an extra layer of protection against sweat, dirt, stains, and dust mites. They cover any hollows in your mattress and evenly distribute body weight, providing a better sleeping experience. 
  • Try draw sheets. They are special sheets specifically made to transfer or position ill or injured people, plus those with mobility issues. They are commonly made from cotton and feature a protective waterproof layer enhancing their moisture absorbency. 

Do Mattress Toppers Make You Hot?

Yes, depending on the material, mattress toppers can make you feel hot. Some toppers eliminate heat, making you sleep more relaxed, but others retain heat, which makes you sleep hotter. Gel foam mattress toppers are cool and relieve your body from heat because they enhance air circulation. 

Down and feather toppers are extra soft, comfortable, heat absorbent, and regulate body temperature. Wool is a natural insulator that absorbs body heat and controls body temperature, providing relief for hot sleepers. Avoid synthetic latex toppers, microfiber leather, and polyester blended mattress toppers, they retain heat. 

A good night’s sleep is something everyone craves. But feeling too hot or sweaty at night can affect your quality of sleep. While memory foam mattresses are one of the most comfortable sleeping surfaces, they often get hot and uncomfortable. Since heat retention is a big concern for hot sleepers, why not try out these tips to stay cool on a memory foam mattress? Given the many kinds of foam mattresses available, you can also select a new cooler one.
