Thermal comfort is one of the most critical factors influencing sleep onset and sleep continuity. Understanding the science behind body temperature regulation during sleep helps you design a sleeping environment that promotes uninterrupted, restful nights.
How Body Temperature Affects Sleep Quality
To initiate sleep, your body’s internal core temperature must drop by approximately one to two degrees Fahrenheit. Excess heat retention in your mattress traps thermal energy around your skin, preventing this natural cooling mechanism and triggering night waking, sweating, and restlessness.
Sleep surfaces equipped with phase-change materials and conductive cooling fibers actively absorb, store, and dissipate heat away from the body, maintaining an optimal temperature throughout the night.
Advanced Thermoregulation with Serta iGlacier
Engineered with cutting-edge cooling technology, the Serta iGlacier collection provides instantaneous surface cooling and continuous airflow. Incorporating high-density gel-infused memory foam and cool-to-the-touch fabric covers, iGlacier actively prevents heat accumulation.
By maintaining a cool sleeping surface, the Serta iGlacier allows your body to remain in deep REM and slow-wave sleep stages longer, ensuring you wake up refreshed and fully energized.
