Sleep is critical for physical health and mental well-being and sleep disturbances have been associated with a range of adverse health effects. At the same time, sleep disturbances are very common in modern societies. In Germany, about 30% of the population reported clinically relevant sleep problems in the past four weeks in a representative survey conducted between 2008 and 2011. The overall increase in numbers over the past 20-30 years suggests that several factors related to modern lifestyle may negatively affect sleep. In this symposium, we would like to revisit different aspects of such a modern lifestyle and discuss their relationship to sleep, physical health, and mental wellbeing. Specifically, Johanna Schwarz’s presentation will focus on the effect of sleep deprivation on the response to psychosocial stress. Next, Sandrine Baselgia will show how arousing effects of cliff-hangers and binge-watching of Netflix series modulate sleep. Christine Blume will present findings on how artificial light exposure before sleep affects neuroendocrinology, sleep quality, and basic human brain functions. The symposium will be concluded by Christian Benedict, who will present research on how acute sleep loss affects weight control as an important health factor. Altogether, this symposium highlights the effects of several characteristics of a modern lifestyle on sleep and investigates their relevance for mental and physical health. The symposium will be concluded with a broader discussion on how the research findings might translate into societal efforts to promote better sleep.
