Our circadian clock evolved in the presence of a natural light/dark cycle. In this time of social distancing and self-isolation, people spend an increasing amount of time indoors, with low levels of daytime lighting, the use of electric light at night, and limited exercise possibilities. These drastic changes in our daily schedules can send confusing signals to our circadian clock and disrupt our sleep, which may have consequences for our health and wellbeing. We would like to remind people of the benefits of daylight exposure, exercise, and regular meal timing on sleep and health, including the immune system. We will be hosting an Ask Me Anything (AMA) session on Reddit this Wednesday, March 18 from 3 pm – 6 pm ET (7 pm – 10 pm GMT), during which we will address your questions on the importance of biological rhythms and sleep.
