Brief Description (Abstract):

Melatonin rhythm and sleep pattern of 6 wintering members of the XXIV Indian Scientific Expedition to the Antarctica were investigated during the entire period of journey and stay at Antarctica. The study was carried out at three different geographic locations. Baseline data collection was carried out in November 2004 at Delhi, India, before departing for Antarctica. On board ship, in December 2004 soon after entering the Antarctic Circle and at Maitri from January 2005 to January 2006. Melatonin was estimated from saliva by ELISA method and sleep was assessed polysomnographically. A consistent delay in the melatonin acrophase was observed during the dark winter months. The mesor of this hormone showed a maximal increase in the midwinter month of June.

Status: Completed

Purpose: The present study was undertaken to find out whether there is any change in the circadian rhythm of melatonin secretion and sleep pattern of tropical Indian expeditioners, who are mostly unknown to the alien Antarctic environment of altered photo period and prolonged isolation and extreme cold.
