SEASONAL PATTERNS OF SLEEP STAGES AND SECRETION OF CORTISOL AND GROWTH HORMONE DURING 24 HOUR PERIODS IN NORTHERN NORWAY
ABSTRACT A group of 7 healthy male subjects was studied in regard to sleep stages and 24 h plasma cortisol and growth hormone patterns during the 4 seasons of the year in an Arctic environment (Tromsø, Norway). No difference in total sleep or sleep stage per cents was found for any of the yearly sea...
