Continuous thermistor skin mapping at 4 anatomical sites (chest, forearm, thigh, calf) combined with EEG polysomnography.
Researchers tested 24 subjects across varying mattress thermal insulation levels in an environmental sleep chamber, measuring skin temperatures and EEG sleep stage transitions.
Facilitates natural nocturnal conductive and convective thermal transfer away from dorsal skin surfaces.
Insulates body heat, driving local contact skin temperature above 35.5 degrees Celsius and inducing sweat.
Poorly ventilated mattress surfaces caused a 31% increase in micro-arousals and fragmented REM sleep, while heat-dissipating sleep systems preserved normal sleep cycle progression.
Core body temperature must drop by 1 to 2 degrees Fahrenheit for your brain to initiate sleep. A bed that allows heat to escape through open coils helps you fall asleep faster and stay asleep longer.
Recommended Firmness Target: Medium-Firm Hybrid
Pair a breathable coil hybrid with natural cotton or Tencel sheets for optimal convective cooling.
