US EditionNew study warns night owls have higher heart risk
Night owls have a 79% higher rate of poor cardiovascular health and a 16% increased risk of heart attack or stroke, linked to modifiable behaviors and circadian misalignment.
- On January 28, 2026, researchers at Brigham and Women's Hospital and Harvard Medical School reported that evening chronotypes had a 79% higher likelihood of poor cardiovascular health, tracking over 300,000 adults in the UK Biobank.
- Because of circadian misalignment, evening chronotypes face added heart risk linked to lifestyle factors like nicotine use, insufficient sleep, and barriers to healthy eating, Sina Kianersi said.
- Using the AHA Life's Essential 8, researchers found about 8% classified as definitely evening people and night owls had a 16% greater risk of first heart attack or stroke over a median follow-up of about 14 years.
- Women showed a stronger link between evening preference and heart health, and targeted programs for night owls could help, with Sina Kianersi noting `The challenge is the mismatch between your internal clock and typical daily schedules that makes it harder to follow heart-healthy behaviours`.
- Given study limitations, chronotype was self-reported once and the UK Biobank sample was mostly white and healthier, but improving sleep, diet and smoking offers public-health opportunities.

According to a study, people with a late chronotype, the night owls, often live unscathed. And that's not necessarily because they go to sleep so late. However, the unfavorable behaviors that increase their risk of cardiovascular disease can be changed.
