Staying up late may not be wise. A new study shows that night owls are more likely to develop common heart conditions than early risers.
Atherosclerosis (hardening and narrowing of the arteries that can lead to angina, blood clots, heart attacks, and strokes) is almost twice as likely to occur in night owls, research shows. University of Gothenburg, Sweden it is Published in Sleep Medicine Journal.
Previous studies have shown that people who stay up late face a higher risk of cardiovascular disease, but circadian rhythms, a person’s 24-hour body clock, affect the heart’s arteries specifically. This study is said to be the first to investigate what kind of influence it has.
Of the 771 study participants between the ages of 50 and 64, 144 described themselves as extreme morning people and 128 as extreme night owls.
Arterial calcification was significant in 22.2% of the early morning group, making it the group with the best outcomes. The extreme evening group had the highest incidence of severe atherosclerosis, 40.6%.
The other three groups (somewhat morning, neither morning nor night, and some evening) were somewhere in between.
Study author Mio Frisk Kobayashi said: “Our findings show that extreme evening chronotypes are associated not only with poorer cardiovascular health in general, but also with more specific risk of coronary artery calcification and arterial calcification. This suggests that it may also be related to the process leading to this.”
Other factors that affect your risk of atherosclerosis include blood pressure, blood lipids, weight, activity level, stress, sleep, and smoking.
Ding Zou, co-author of the study, emphasized that circadian rhythms – fragile cycles that are easily disrupted – are a key factor in disease development.
“We interpret this result as indicating that circadian rhythms are more important early in the disease process,” Zou said. “Therefore, it should be considered, especially in the preventive treatment of cardiovascular disease.”
Another study shows that losing just an hour or two of sleep can easily trigger anxiety. Another study found that getting more sleep on the weekends may help prevent heart attacks.
