The Science Behind Cooling Mattress Technologies
Introduction
A restful night’s sleep isn’t just about soft pillows or plush surfaces it also hinges on maintaining the right body temperature. Many sleepers underestimate how pivotal temperature regulation is for achieving deep, restorative sleep. When your body overheats, it struggles to move smoothly through essential sleep stages like deep and REM cycles. Overheating often leads to frequent awakenings, night sweats, and that groggy feeling upon waking despite having clocked 7–8 hours in bed.
So, why does temperature regulation matter so much for sleep quality? Your body's core temperature naturally decreases as part of its circadian rhythm, signaling it's time to rest. When a mattress traps heat, it disrupts this cooling-down process, making it harder to fall asleep and stay asleep. Research suggests that hotter sleepers experience shorter REM phases,
