Room temperature, humidity, bedding and mattress technology – how the sleep environment influences sleep.
Study from the National Institute of Advanced Industrial Science and Technology (Japan). The authors examined how humid heat during the night influences sleep, thermoregulation, melatonin secretion and the microclimate under the duvet. High humidity combined with heat significantly impaired sleep quality more than dry heat – an important factor for the duvet climate.
Study from Toyohashi University of Technology on the effects of low room temperatures (3 °C, 10 °C, 17 °C) on the sleep of young men using bedding. The results show that more extreme cold (3 °C) significantly burdens thermoregulation and reduces sleep quality, while at 10 °C and 17 °C the duvet can sufficiently protect core temperature.
Study on the effect of a temperature-controlled mattress pad (8sleep Pod) after one week of use. The results show improvements in sleep quality and cardiovascular recovery. The study demonstrates that active temperature regulation in bed has measurable, clinically relevant effects on sleep and cardiovascular parameters.
Study on the effect of bed socks on sleep quality and thermoregulation in a cool environment. Wearing bed socks led to faster sleep onset and longer sleep duration. The researchers show that warming the feet increases distal skin temperature and thereby promotes peripheral vasodilation – a key mechanism for sleep onset.
Study from the Japanese Red Cross Akita College of Nursing on the distal–proximal skin temperature gradient (DPG) before sleep onset in infants. The researchers showed that the DPG is a reliable predictor of sleep-onset latency – already from infancy. This demonstrates that the thermoregulatory mechanism of sleep onset functions from the earliest stages of life.
