Extensive research was conducted to investigate the relationship between objectively measured sleep parameters and the risk of cardiovascular disease (CVD). The study, "Accelerometer-derived sleep onset timing and cardiovascular disease incidence: a UK Biobank cohort study," published in November in European Heart Journal – Digital Health, a journal of the European Society of Cardiology (ESC), found that 3,172 participants (3.6 percent) developed cardiovascular disease over an average follow-up of 5.7 years. The study discovered a strong link between sleep timing and CVD risk, especially in women.

Sleeping between 10 p.m. and 11 p.m. is associated with a lower risk of developing heart disease when compared to other bedtimes, according to new research. The study discovered that sleep onset at midnight or later was associated with a 25% increased risk of cardiovascular disease when compared to sleep onset between 10pm and 10.59pm. There was a 12% increase in risk from 11 p.m. to 11.59 p.m., and a 24% increase in risk for falling asleep before 10 p.m.

The body has a 24-hour internal clock, known as the circadian rhythm, which aids in the regulation of physical and mental functioning. The findings suggest that early or late bedtimes are more likely to disrupt the body clock, which can have a negative impact on cardiovascular health. If the findings are replicated in other studies, sleep timing and basic sleep hygiene may be a low-cost public health target for lowering the risk of heart disease.
