Abstract
Jet lag is a disruption to daily biological circadian rhythms that affect millions of people worldwide each year. Jet lag negatively impacts health, including behavioral changes in mood. Seasonal changes in day length have also been associated with mood disorders. In this study, we aim to understand how jet lag, under different day lengths, affects anxiety and depression. Using the mouse as a model organism, we find that neither jet lag nor day length negatively impacted anxiety or depression. Compared to studies that demonstrate the negative impacts of chronic jet lag on mood, this study reveals a less severe effect on mood within the first two days after jet lag.
