The Heat-Sleep Crisis: Why Temperature Matters
1.1 Sleep Thermodynamics 101
The human body sheds 0.5-1L of moisture nightly, creating a microclimate of 85-90% humidity around bedding. Traditional waterproof encasements trap heat at 34°C+ – prime conditions for microbial growth and discomfort.
Key Findings (Sleep Thermal Comfort Lab 2024):
Hot sleepers experience 63% more mid-night wakeups
42°C mattress surface temp disrupts REM cycles within 20 minutes
Deep Dive:
The interplay between core body temperature regulation and sleep architecture is critical. During REM sleep, the hypothalamus reduces thermoregulation, making external cooling interventions vital. Pairing cooling encasements with thermo-regulating pillows (as covered in our Pillow Technology Hub) creates systemic temperature control.
