We believe in science, and the science is clear. We sleep deeper, with a measurably increased recovery at a cooler body temperature. Our core body temperature should naturally drop every night, but for lots of people and lots of reasons: it doesn't. The thermodynamics of the sleep environment: warm blankets, constant room temperature, unnatural materials in our mattresses sabotage our sleep! OOLER® eliminates all other temperature variances by maintaining the temperature schedule you set all night, every night.
