Although memory foam beds are amazing at pressure relief, they are unfortunately poor thermo-conductive materials. This makes them more susceptible to heat build up and trapping when we sleep on them. When summer rolls around and it becomes hot outside, it’s only going to get worse.
Heat affects our sleep, and despite our body’s best efforts to naturally cool off through sweating and to drift into sleep mode, it be disruptive. We love memory foam, but it can make sleep very difficult because of poor temperature regulation.
Keep on reading. We will take a look at five simple ways to cool your memory foam bed.
5 Ways On How To Cool Your Memory Foam Mattress
Freeze your sheets
If you haven’t tried already, consider cooling sheets for your memory foam mattress. As silly as it may seem, placing your bedsheets into the freezer for use later can be a very reliable way for cooler sleep. This solution is not limited to memory foam, either.
You can place them inside a clean plastic bag and into your freezer for a few minutes before bed. It might be a hassle to spend a few minutes doing so every night, but if it means several hours of quality sleep, freezing your sheets can be worth it.
Make more space around your mattress
We often blame our mattress for being too hot for sleep. Sometimes, it’s the environment. Other times, it could be our set up. In other words, the lack of open space underneath our mattress can cause heat build up.
Memory foam in of itself is highly dense and solid. It needs as much open space around it as possible to push and pull hot air built up within it, as we naturally move around in our deep sleep.
Many sleepers use the traditional solid wooden plywood beneath their mattress. This is great for providing a more firm and supportive sleep, but can completely prevent airflow for your mattress to breathe. An improvement can be to get rid of the frame around your mattress, and switching from a thick foundation to using a metal bed frame. This will let your bed keep its shape while providing adequate support for evenly distributing your body weight to relief pressure.
Switch out your pillow
Your pillow can make a huge difference to the general temperature of your bed. If you’re like most sleepers, you might find yourself scrounging around with your hands underneath your pillow for a cooler spot.
Side note: It might be a telling sign that your environment is simply too hot and needs to be cooled down with air condition or better airflow (if possible) when your mattress feels hot, but there are cool spots on your bed.
There are a few types of pillow fillings that can make sleep generally cooler.
- Memory foam gel pillows is a hit or miss for some people, providing comfortable head support for side and back sleepers, but may still be too hot for some
- Down filling or down alternative filling can be a suitable choice with better airflow, but might not have enough density or firmness
- Water pillows can be a suitable choice, being better at regulating temperature in general
You really do need a cooler environment
Regardless of mattress, some environments simply demand cooled temperatures. For example, it could be simple summer months heat wave, the fact that you are located on the second floor, or sleeping in a room with little to no air circulation. If you have your windows open and sun is shining through, you might want to consider keeping your curtains closed throughout the day and night.
Whatever the circumstances is, no matter how well-built your mattress might be for cooler sleep, it might not be able to succeed with a bedroom environment that is simply too hot for any solutions.
Here are a few things you can consider for setting yourself and your mattress up for success:
- Window curtains are shut, preventing the beaming heat of sunlight from warming up your bedroom
- Your room has air circulation, with a proper ventilation system to push and pull air flow (a fan can help)
- Using your home or portable air conditioning to cool your room
Ideally, for most adults, you are looking for a room temperature between 60-65°F (16-18°C). Take note of what works best for you as you sleep on your memory foam mattress.
Own a mattress designed with cooler sleep in mind
You might not be at the right time to purchase a new mattress, and that’s fine. However, it’s important to know the next time you can purchase a new bed to consider a mattress construct and design that takes airflow and cooler sleep into consideration.
Some things you would be on the look out for include:
- Open-cell structure, aerated designs, and/or convoluted layers for improved airflow
- Cooling gel, copper, bamboo, and any other cooling ingredients that reduce foam density and absorb heat
Alternatively, it might be worth considering latex mattresses or latex hybrid mattresses for your next purchase. Latex, a fundamentally different type of foam, provide a bouncier alternative to memory foam. They also have less density and can provide an organic sleeping bed that have minimal motion transfer and initial off-gassing odors.
Innerspring mattresses also have a ridiculous amount of space for significantly better airflow. They are the bouncier version of latex, but might not have the same pressure relief you can get from latex or memory foam.
