Adherence
Increased sleep irregularity (defined as higher standard deviation of daily sleep duration) is associated with increased odds of incident obesity, essential hypertension, hyperlipidemia, major depressive disorder, and generalized anxiety disorder.
Focus on keeping your sleep schedule consistent. Going to bed and waking up at roughly the same time every day is critical for preventing obesity, hypertension, and depression, even if you are getting the recommended 7-9 hours of total sleep. Use wearable data to track your sleep regularity (consistency) rather than just total hours.
Increased sleep irregularity (per hour change in s.d. of daily sleep duration) was associated with a variety of incident psychiatric, sleep and metabolic disorders. Chronic conditions associated with increased sleep irregularity included essential hypertension (1.56; 1.35–1.81), hyperlipidemia (1.39; 1.20–1.61) and obesity (1.49; 1.28–1.73). We also observed increased odds of several psychiatric disorders, including major depressive disorder (1.75; 1.52–2.01), anxiety disorder (1.55; 1.35–1.78)...
Why this rating
Large sample size (6,785 participants), long monitoring period (median 4.5 years), objective wearable data, but observational design limits causal inference.
