So let’s dive in and find a solution for a more comfortable night’s sleep!

Why Do Mattresses Get Hot?

There are several factors that can cause a mattress to get hot. These include:

  1. Materials: Some mattress materials, such as memory foam, are known to retain heat. This is because they conform closely to your body, reducing airflow and trapping heat.
  2. Breathability: A mattress that doesn’t breathe well won’t let enough air flow through, which keeps heat in.
  3. Your body heat: Naturally, our bodies generate heat during the night, and some people tend to sleep hotter than others.
  4. Bedding: Heavy or non-breathable bedding materials can also contribute to a hot sleeping environment.

How to Keep Your Mattress Cool

Here are some practical solutions to help keep your mattress cool:

  1. Choose a breathable mattress: Opt for a mattress with better breathability, such as innerspring or hybrid mattresses, which tend to sleep cooler than memory foam mattresses. Check out our guide to choosing the right size to help you find the perfect fit.
  1. Invest in a cooling mattress topper: A cooling mattress topper, made from materials like gel-infused memory foam or latex, can help regulate your sleeping temperature. Browse our best mattress toppers for adding comfort to find one that suits your needs.
  2. Use cooling bed sheets: Opt for lightweight, breathable sheets made from materials like bamboo, Tencel, or moisture-wicking fabrics. Check out our recommendations for the best sheets for DreamCloud mattresses.
  3. Add a mattress pad or protector. A breathable mattress pad or protector can create a barrier between your body and the mattress, which helps heat to escape.
  4. Adjust room temperature: Ensure your bedroom temperature is set to a comfortable level, typically between 60-67°F (15-19°C).
  5. Use a fan or air conditioner: A fan or air conditioner can help circulate air and keep your sleeping environment cool.
  6. Try moisture-wicking sleepwear: Sleepwear made from moisture-wicking materials can help keep you dry and cool throughout the night.
