How a Cooler Beds Promote Deeper Sleep

A good night’s rest is one of the most important things we can do for our bodies. It allows us to re-energize, stay in good health, and feel ready to take on the day.

However, almost 41% of people report having trouble sleeping due to feeling too hot throughout the night. We all know the feeling of waking up in the middle of the night sweaty, sticky, and agitated by the unwanted heat trapped in our beds.

But did you know, according to science, our bodies are designed to sleep in cooler environments? If you are among those battling heat for a restful night’s rest, it might be time to buy a mattress that’ll support you on your journey to a cool night’s sleep.

What are cooling beds?

For those unsure of what cooling beds are and how they work, understanding their composition is a great place to start. Most commonly, cooling mattresses use temperature-regulating materials, such as gels and memory foams, that can draw heat away from the body – keeping your temperature regulated throughout the night to improve both your comfort and quality of sleep.

Benefits of Sleeping Cool

Besides the obvious comfort sleeping cooler gives you, cooling beds help you sleep more soundly. This is a result of our body’s temperatures naturally dropping throughout the night as our metabolism slows. In fact, we tend to experience the most significant drop in body temperatures around 90-minutes after we fall asleep, when we enter Rapid Eye Movement (REM) sleep, which is where dreams most commonly occur. REM sleep is very beneficial to our body’s recovery and rejuvenation from the day and sleeping at cooler temperatures helps ensure a seamless transition to REM.

Another critical factor to our body’s ability to sleep is our melatonin levels, which is a hormone that attributes to our natural sleep-wake cycle. When our body senses a drop in external temperature, our melatonin levels increase and, as a result of this, our internal temperature drops even more to support a deeper, more sound sleep.

Our mood is also affected by poor sleep. When our body gets too hot and too tired, our levels of cortisol begin to rise, which is the stress hormone that contributes to feelings of depression.

There are several different benefits of sleeping cool that each contributes to a night of longer, deeper sleep. That’s why we recommend a mattress or mattress topper that allows for these conditions to vastly improve your quantity and quality of sleep. At MLILY, we’ve created top-of-the-line sleep solutions specifically designed for hot sleepers.
