Sleep Irregularity and Heart Disease

Caption

The two graphs on the left show 7-day sleep patterns: Highly regular sleepers (graph with green lines) and highly irregular sleepers (graph with orange lines). The colored lines correspond with the graphs on the right showing cardiovascular disease (CVD) risk in regular sleepers versus CVD risk in persons with irregular sleep patterns. Compared with people who have the most regular sleep patterns, study participants with the most irregular sleep patterns had more than twice the risk of developing CVD events over a follow-up period of about five years.
