More Sleep Benefits People With Type 1 Diabetes

Researchers published the study covered in this summary on medRxiv as a preprint that has not yet been peer reviewed.

Key Takeaways

  • Longer sleep duration significantly associated with lower next-day general stress and reduced negative affect in people with type 1 diabetes.

  • Optimizing sleep duration in people with type 1 diabetes may help manage their stress and improve their emotional well-being.

Why This Matters

  • No prior study specifically examined the relationship between sleep duration and stress and positive or negative affect in the daily life of people with type 1 diabetes.

  • Adults with type 1 diabetes report more sleep disturbances than do people without type 1 diabetes, possibly related to the risks these people face from hypoglycemia, hyperglycemia, and increased glucose variability.

Study Design

  • Study of 166 adults diagnosed with type 1 diabetes for at least 1 year on stable treatment and enrolled during June 2020-February 2022 in the Function and Emotion in Everyday Life with Type 1 Diabetes study.

  • The researchers measured and analyzed numerous clinical parameters, including sleep duration, general and diabetes-specific stress, and positive and negative affect.

Key Results

  • The enrollees averaged about 41 years old, and 55% were women. At baseline, 14.5% had depression and 7.8% had anxiety.

  • Average sleep duration was 7.3 hours.

  • Longer sleep duration significantly associated with lower general stress but not with diabetes-specific stress.

  • Longer sleep duration significantly associated with lower, next-day negative affect but had no significant association with any positive affect variables.

  • Among covariables, greater levels of pain significantly associated with more negative affect and higher general stress, but these variables showed no significant associations with average blood glucose levels.

  • General stress levels were lower during weekends compared with Mondays.

  • No differences existed in these associations between men and women, or for those with or without depression or anxiety.


  • The study was observational and hence the reported associations cannot address causal relationships.

  • Data collection occurred during theCOVID-19 pandemic, which interfered with sleep, stress, and mental health and may limit generalizability.


  • The study received no commercial funding.

  • None of the authors had disclosures.
