Abstract
Significance

We observe that a change from very alert to very sleepy can decrease social contact by approximately 70%. We also reveal moderators of this effect, such as time of day. This finding provides a perspective on, and possible mechanism as to, why sleep disturbances and other causes of sleepiness (such as medicine side effects or shift work), are associated with poorer health outcomes. It is especially urgent to understand the causes of decreased social activity, as rates of social isolation and loneliness are reported to be rising, as are rates of sleep disturbance. The results provide directions for future research, for example regarding whether interventions to alleviate sleepiness can be an effective way to improve both short- and long-term well-being.
