Cooling Mattresses 101: What Makes Them Beat the Summer Heat?

Apr 13, 2025 Jonas

The Science Behind Cool Mattresses

First, let's explore the root cause of overheating at night. During sleep, the human body initiates a dormant mechanism through a drop in body temperature, but if the mattress has too much heat storage capacity, this physiological law will be disrupted. If the heat released by the body to cool down cannot be discharged in time, it will form a “heat retention effect” in the sleep microenvironment.

Mattresses and bedding materials act as insulation, transferring heat back to the body surface and forcing the body to repeatedly activate the heat dissipation mechanism. This vicious cycle not only disrupts the body's self-regulation of temperature but also inhibits the low-temperature environment needed for deep sleep.

Memory foam mattresses are particularly obvious in this problem. While traditional spring and composite mattresses form air channels through breathable layers of cotton and wool, pure memory foam mattresses are essentially like an “insulated box” that locks in body heat due to its dense foam structure.

For this reason, the modern cool memory foam mattress introduces two core technological breakthroughs:

  • Gel-infused memory foam: through high thermal conductivity gel particles actively adsorb body heat and release it through lateral diffusion.
  • Three-dimensional heat dissipation architecture: combining open hole structure and airflow guiding layer design to build heat emission channels.

Take the example of the Eshine cooling mattress, which adopts “honeycomb open cell foam” technology:

  • Three-dimensional interconnected holes accelerate air convection and prevent localized heat accumulation.
  • Dynamically responsive support layers synchronize the formation of ventilation gaps while supporting the body.
  • Continuous heat exchange throughout the night to maintain a comfortable microclimate on the body surface.

How Airflow Affects Body Temperature During Sleep

If you're naturally a hot sleeper, a cool mattress alone may not solve all your problems. Airflow is an important factor in your sleeping environment - you need proper air circulation throughout your sleeping environment, not just the mattress itself.

An easy way to increase airflow and heat dissipation is to place your mattress on a slatted base, rather than a solid platform, so that the mattress is ventilated on all sides. While you can place a traditional innerspring mattress on a box spring to achieve the same effect, we don't recommend box springs for memory foam or hybrid mattresses. They are too heavy and require a sturdier base.

Lightweight, breathable bedding, such as cotton, bamboo, or linen sheets, also wicks away moisture and allows heat to escape instead of sticking to your body all night. A cotton blend sheet set is a good choice. It's made from naturally breathable and moisture-wicking cotton and bamboo and is luxuriously soft, cool, and comfortable.

If you sleep hot, or suffer from hot flashes or night sweats, then a bed cooling system will change your life. These systems use forced air or water cooling to enhance airflow and temperature regulation - some even come with app controls for precise temperature settings.

How Eshine Keeps You Cool

The Eshine mattress takes coolness to another level by utilizing natural breathable icy cool fabrics and an advanced mattress design that provides the perfect balance of coolness and comfort. Pocketed springs enhance airflow and a cool memory foam layer actively dissipates heat as you sleep.

At Eshine, we prefer to keep a healthy sleep environment as natural as possible. That's why we use our signature perforated foam to provide targeted cooling without using too many chemicals.

As you change positions during the night, this foam expels hot air and draws in cool air for better air circulation and heat dissipation. The cotton and merino wool mattress cover adds another layer of natural temperature regulation to keep you sleeping cool all night long.

Benefits Of A Cooling Mattress

For hot sleepers and those who suffer from frequent hot flashes or night sweats, a cooling mattress offers more than just sweat-free sleep. A cooling mattress keeps your body temperature stable on hot nights, which in turn improves your overall sleep quality. You'll spend more time in the deeper stages of sleep such as slow wave sleep (SWS) and rapid eye movement (REM) sleep, where most of your body's recovery takes place.

If you're a hot sleeper, you'll toss and turn less and wake up less often due to sweating. You'll also get better positioning and targeted support with Eshine's Cool Mattress, a perfect blend of comfort, support, and pressure relief for your back, hips, and shoulders. You'll sleep faster and wake up refreshed instead of groggy and overheated.

Tips to Enhance the Cool Mattress Experience

While a cool mattress can make a big difference, there are a few other tips to keep your sleeping environment cool:

(1) Purchase breathable sheets: Natural fibers such as cotton or linen are perfect for keeping air circulating in and out of your mattress. Choose lightweight, moisture-wicking sheets to enhance the cooling effect.

(2) Monitor room temperature: The room temperature should be between 60 and 65 degrees Fahrenheit for optimal sleep. Use a fan or air conditioner to keep the environment comfortable so you don't have to let a cool mattress do all the work.

(3) Use Cooling Pillows and Mattress Protectors: If you need extra relief, try cooling pillows and mattress protectors like Eshine's Ultra-Cool Memory Foam Pillow and Ultra-Cool Mattress Protector, which complement the cooling properties of your mattress.

(4) Consider a Cooling Mattress: Cooling mattresses utilize heat-dissipating materials that improve the temperature control and breathability of the mattress, making them ideal for heat sleepers.
