Energy expenditure during sleep in men and women: evaporative and sensible heat losses

A direct calorimeter study involving 59 apparently healthy adults (21 women, 38 men) evaluated the mean value, the within- and between-subject variability, the trend in heat loss, and heat production during sleep. Increased heat loss during sleep was attributed to an increase in evaporative heat los...

Summary:A direct calorimeter study involving 59 apparently healthy adults (21 women, 38 men) evaluated the mean value, the within- and between-subject variability, the trend in heat loss, and heat production during sleep. Increased heat loss during sleep was attributed to an increase in evaporative heat loss. Heat losses during sleep fell more in men than in women (ca. 30% vs. ca 14%) and approached basal levels during the last hour of sleep. Heat production was estimated in men to be ca. 9% less than heat loss.(wz)
