Sleep problems are far more common than many people realize, with short sleep affecting 26% of adults worldwide in population based studies and 8% of US adults reporting that sleep issues disrupt daily life at least a few days a week. The twist is how these sleep patterns ripple outward, from healthcare costs and car accident risk to depression, cardiovascular disease, and even how well insomnia responds to treatments like CBT I. Below, you will find the key sleep statistics that connect what happens at night to outcomes that follow you the next day.
