Thermorégulation au cours du sommeil et de la veille chez le nouveau-né

This paper reviews the close relationship between thermoregulation and sleep in neonates considering various aspects: (1) thermoregulatory responses differ between sleep stages. In contrast to human or animal adults whose thermoregulation is impaired or abolished, respectively, during REM sleep, in neonates thermoregulation is at least as efficient in active sleep as in quiet sleep; (2) body temperature and sleep-wake cycle rhythms are closely related; (3) manipulation of thermal parameters can influence sleep quantity and structure. In neonates, active sleep is increased by cold challenge, whereas quiet sleep is generally decreased. Sleep duration is reduced as resulting from earlier final awakening.
