We all experience stress in our lives, whether it is brought on by our jobs, our personal lives or even just standing in traffic jam. Stress is inevitable and can impact our lives in many ways. In general, stress is good for us. But sometimes it can take a serious toll on our everyday functions — especially disturbing our sleep and our brains’ ability to adapt to the environment.


The main focus of the Bergen Stress and Sleep Group is the role of stress in physiological and psychological recovery, causes of disturbed sleep (especially shift work and light exposure), measurement of sleep quality and circadian rhythms, effects of acute and chronic stressors in different stages in life- on wakefulness, sleep and circadian rhythms, and the relationship between stress, sleep and mental health (affective disorders and post-traumatic stress disorder), at both the basic science and clinical levels.

Our approach is essentially transitional, with clinical and human data informing our animal model research, and vice versa. Our fields of interest include, but are not restricted to, animal models that allow basic studies of regulatory mechanisms of stress, sleep and wakefulness, animal models that allow simulation of shiftwork in humans and its biological and psychological consequences, post-traumatic stress disorder and affective disorders in the human population and potential animal models thereof which allow identification of potential markers for risk. In these endeavors, we collaborate with partners at the local, national and international levels.

Summer school

Circadian Rhythms and Sleep

Humans spend roughly one-third of their lives asleep. The aim of the course is to provide knowledge of the function that is served by circadian rhythms, sleep and the mechanisms by which circadian disruption and sleep insufficiency degrades mental and physical health, safety and productivity – and...
