The University of Oulu (Finland) found that irregular sleep rhythms are associated with worsening cardiovascular health in middle-aged people. The results of the study were presented as follows: magazine Journal of Activity Sedentary and Sleep Behavior (JASSB).
A total of nearly 3,700 volunteers aged 46 years old participated in the research. They completed health and lifestyle questionnaires and participated in a clinical examination where body weight, blood pressure, blood lipid levels and an oral glucose tolerance test were measured. Physical activity and sleep rhythm were measured using a wrist-worn activity tracker.
On average, participants went to bed at 11 p.m., woke up at 7 a.m., and spent an average of about eight hours in bed. For half of the participants, bedtime, wake-up time, and time in bed varied by at least an hour per week, on average.
