Torbjörn Åkerstedt

Torbjörn Åkerstedts groups research is focused on the effects of stress on sleep physiology, the behavioral factors that regulate sleep (time awake, time of day, amount of prior sleep), the recuperative value of sleep (in terms of cognition, fatigue, health), factors in society that disturb sleep, sleep loss and accident risk, interventions to improve sleep.

Women and sleep (the relation between polysomnographical measures and perceived sleep quality, subjective health, sleepiness and aging.
