Study Finds Night Owls at Higher Risk for Heart Issues
A new study has revealed that adults who identify as “night owls” may be at a greater risk for heart-related problems. Published in the Journal of the American Heart Association, the research highlights how a person’s natural sleep pattern can impact their cardiovascular health.
The study analyzed 14 years of data from the UK Biobank, focusing on around 300,000 adults who averaged 57 years of age. Of those surveyed, about 8% described themselves as “definitely evening people,” while 24% identified as “definitely morning people.” The remaining 67% felt they were somewhere in between.
The heart health of participants was assessed using the American Heart Association’s “Life’s Essential 8” score, which takes various factors into account, including exercise, diet, blood pressure, and smoking habits. The results showed that night owls had a 79% increased risk of poor heart health compared to those who fell into the intermediate category. They were also found to have a 16% higher risk of experiencing a heart attack or stroke.
Interestingly, those who woke up earlier tended to have slightly better heart health ratings, a trend particularly noticeable among women. Lead researcher Dr. Sina Kianersi explained that night owls often experience “circadian misalignment,” where their internal body clocks don’t align with the natural day-night cycle. This misalignment can lead to unhealthy behaviors, such as poor diets and irregular sleep patterns.
Cardiologist Dr. Bradley Serwer noted that lifestyle choices play a crucial role in heart health. He emphasized that quality sleep is essential, but it is one of many factors that contribute to cardiovascular diseases.
The findings offer valuable insights that can help healthcare providers tailor consultations and recommendations for patients, aiming to prevent heart-related issues. However, the study does have limitations, such as not proving that staying up late causes heart problems, and it mostly involved a demographic that may not represent the broader population.
Further studies are needed to clarify the specific relationship between sleep patterns and heart health.
