Recent research analyzed UK Biobank participants and found that a definite evening chronotype is linked to a 16% higher risk of cardiovascular disease (CVD), primarily mediated by a lower achievement of the American Heart Association's Life's Essential 8 (LE8) health metrics. The study highlighted nicotine exposure, sleep deprivation, and poor dietary habits as significant contributors affecting LE8 scores. With a cohort of 322,777 adults followed for nearly 14 years, the findings raise concerns about the cardiovascular health of those with evening preferences based on their lifestyle choices.
