Characterization of the thermophysiological comfort of duvets in consideration of the bed cave

Sleep is a fundamental need for humans. On average 1/3 of the lifetime is spent in bed. Important for a healthy sleep is the duvet. This should have sufficient heat insulation and should ensure a dry bed climate at the same time. The thermophysiological comfort of classic duvets can be rated via ski...
