ANN ARBOR According to researchers at the University of Michigan, COVID-19 stay-at-home orders have impacted much more than our social lives - they have impacted our sleep patterns as well. The research team developed the free Social Rhythms iOS app to help users understand their own sleep rhythms and give tips on how to maximize sleep during extended periods of quarantine. Scientists are hoping that data generated by the app could shed light on lockdowns and circadian rhythms -- our internal clocks that regulate everything from sleep and wake time to eating and digestion. In short, many of us may be experiencing circadian disruption which could lead to fatigue, mood changes, changes in sleep patterns and decreased immune function, Forger added. What also is very unhealthy is some people are going to bed at 2 a.m. one day and then 8 p.m. the next day and midnight the next day, Forger said in a statement.
