Some people are more productive in the morning, others in the evening. But recently, studies have begun to emerge that suggest that the owl rhythm may be associated with heart problems.. A new study published in the Journal of the American Heart Association supports this idea, Live Science reports..

Scientists used data from UK Biobank. They followed more than 322,000 adults aged 39 to 74 for almost 14 years. Researchers sought to determine how "

Study participants talked about what sleep and wakefulness they prefer. Accordingly, they were divided into “morning”, “intermediate” or “evening” types. Heart health was assessed using the American Heart Association's Life's Essential 8 score, which rates heart health on a scale of 0 to 100 based on eight factors: smoking, diet, exercise, blood sugar, weight, blood pressure, cholesterol and sleep quality. Higher scores indicate better cardiovascular health.

The study found that those with a distinctly evening lifestyle were 79% more likely to have low rates overall and 16% more likely to have a heart attack or stroke over about 14 years of follow-up than those with an intermediate rhythm.. People with a clear morning sleep pattern were 5% less likely to have low levels than people with an intermediate sleep pattern..

But why does this happen Night owls in the study performed worse on various lifestyle factors compared to people with average sleep levels. For example, they had 54% more nicotine intake, 42% worse sleep quality, 19% less physical activity, and 8% worse diet.. In contrast, those who were more active in the morning tended to consume less nicotine and eat better than those with an average rhythm..

When these differences are taken into account, it turns out that 75% of the increased risk of cardiovascular disease in owls is associated with lifestyle rather than chronotype. Among these factors, smoking made the largest contribution (34%), followed by poor sleep (14%), high blood sugar (12%), and diet and body weight (11% each)..

“Factors influencing overall cardiovascular health are modifiable, including nicotine exposure. So for people who consider themselves night owls, this is a compelling reason to be even more proactive about these core aspects,” said study lead author Sina Kianersi, a postdoctoral fellow at Brigham and Women's Hospital and Harvard Medical School.. He also added that other influencing lifestyle factors include physical activity level, blood pressure and cholesterol levels.

Lack of sleep and its poor quality negatively affect the human body. It is better to fall asleep between ten in the evening and four in the morning. This is the most valuable time for sleep, points out Candidate of Biological Sciences, teacher at the Kiev-Mohyla Business School and the Maybutni School, co-author and head of the Zminotvortsi methodology, neuroscience specialist Pyotr Chernomorets in an interview with the editor of the ZN education and science department.
