Analyses show that staying up late is often linked to unhealthy daily habits – poor diet, insufficient sleep, and high rates of smoking – all of which increase the risk of cardiovascular disease.Researchers believe these findings offer real opportunities to improve heart health by changing daily behaviors.
The study analyzed health data from over 300,000 adults with an average age of 57 who participated in the UK Biobank study. Researchers aimed to understand the relationship between chronotype – a natural preference for sleep and wakefulness – and indicators of heart health.
Participants were categorized based on their self-reported chronotype: around 8% went to bed around 2 a.m. and were more active later in the day, while 24% tended to go to bed and wake up early.
The majority – 67% – fell into an intermediate category that didn’t clearly fit either pattern.
Heart health was measured using 8 essential criteria.
