Topic: circadian misalignment

Night shift work is associated with adverse health effects and leads to misalignment between timing cues from the environment and the endogenous circadian clock. In this presentation, I will discuss the effect of circadian misalignment induced by night shift work on peripheral 24-h rhythms on the transcriptome and metabolome in humans, presenting findings from both controlled laboratory studies and field studies. Furthermore, I will highlight the importance of taking into account interindividual differences in the response to circadian misalignment.

What happens to human sleep and circadian rhythms in space? There are many challenges that affect sleep in space, including unusual patterns of light exposure and the influence of microgravity. This talk will review the causes and consequences of sleep loss and circadian misalignment during spaceflight and will discuss how missions to the Moon and Mars will be different than missions to the International Space Station.
