Going to bed late and waking up late (Evening Chronotype) is associated with increased health risks.

(Lotti et al., 20201)

Chronotype refers to individual differences in sleep timing and wake up time preferences for a given time of day (Circadian Rhythm). Morning types prefer to get up and go to bed early, while evening types get up and go to bed later.

This meta-analysis of 39 observational studies assessed energy intake, BMI, blood lipids, fasting blood glucose, blood pressure, and risk of chronic diseases.

Compared to the morning chronotype, the evening chronotype was associated with increased blood glucose, LDL-C, triglyceride, type 2 diabetes & depression.

Those who do jobs require staying awake overnight should pay more attention to nutrition and exercise. You probably be able to minimize the risks with proper nutrition and exercise. Consider supplementing Melatonin & Vitamin D.
