Sleep ecology: Studying human sleep dynamics in real life and large numbers


Sleep remains an enigma: we don’t know what function(s) sleep actually fulfils and why it is so often altered in disease and aging. A major limit to progress in sleep research is the difficulty of recording sleep outside the sleep laboratory, thus hindering large-scale sleep studies and big-data approaches.
Importantly, sleep is not a simple uniform state but shows intriguing temporal dynamics, with many bodily processes, from brain activity to hormone levels, changing over time during a single sleep episode. Some changes are gradual, whereas others reappear in cyclical fashion commonly known as sleep cycles. It is especially these sleep dynamics that cannot be captured by simple questionnaires but depend heavily on laboratory measurements.
Using simple wrist activity recordings (similar to those in health trackers), we extract such sleep dynamics from sleepers’ movements. Using these dynamics for a first large-scale exploration of human sleep in real life, we found sleep dynamics to change markedly with age and to be altered by shift work and psychiatric disease. We now use this approach to study human sleep dynamics under the most diverse conditions, in health and disease and across all ages to identify factors altering sleep dynamics and the health impacts of such sleep dynamics.

Effect of school starting times on adolescent sleep behaviour

In many cultures, teenagers are chronically sleep deprived because their typically late sleep times conflict with the relatively early start times of theirs schools. This is a pressing problem since teenage sleep deprivation is linked with reduced performance and substantial long-term health risks including diabetes and depression.
Is a delay in school starts an effective countermeasure to teenage sleep deprivation? We study this at the Gymnasium Alsdorf, a high school close to Aachen, Germany, where a flexible school start system was introduced early 2016 for all senior students.

Individual factors influencing jetlag severity

How much the circadian system, our 24-h-body clock, influences basic body functions like sleep, metabolism or concentration and alertness becomes apparent when this system is disturbed - for example through long-distance flights across time zones. The symptoms we experience after such flights are summed under the term ‘jetlag’, a de-synchronisation of the circadian system with the external world but also internally between different organ systems.
There are huge differences in how every person is affected by jetlag. The main goal of our prospective cohort study is to identify individual factors that influence the intensity and duration of jetlag symptoms in travellers including psychosocial factors like expectation
