POLYPHASIC SLEEP IN OCEAN SAILING

Learning to sleep in extreme conditions

Sleep management in a round the world regatta is essential for optimum performance and recovery.

This is a study into the design of a polyphasic sleeping plan adapted for transoceanic sailing with two crew during the Barcelona World Race 2014/15. Natural morning and evening tendencies were respected during the watch shifts and physical and cognitive performance was optimised.

The recommendations on polyphasic sleep lead to an improvement in the quality of rhythms (improved stability and relative amplitude) and sleep (depth) with respect to the sleep achieved in the previous period, where recommendations were not being followed. This meant that sailors’ overall sense of wellbeing improved. 

The project was carried out by Beatriz Rodriguez-Morilla, at the Chronobiology Laboratory at the University of Murcia; Carla Estivill-Domenech, Estivill Sleep Clinic and the Hospital Quirón-Dexeus in Barcelona; Juan Antonio Madrid from the Chronobiology Laboratory at the University of Murcia; Eduard Estivill, at the Estivill Sleep Clinic and the Hospital Quirón-Dexeus in Barcelona.
