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: Seek a mattress designed for maximum airflow. Options like innerspring or hybrid mattresses generally offer cooler sleep experiences compared to traditional memory foam. For insights into selecting the ideal mattress, consider our guide on the best mattresses for chronic pain, emphasizing comfort and support.
  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.
