A study by scientists at the University of Tokyo concluded that long naps are linked to a greater likelihood of type 2 diabetes.
Researchers found the link after analyzing observational studies involving more than 300,000 people.
They state that individuals with chronic illnesses and undiagnosed diabetes often experience daytime fatigue.
However, they clarified that there is no evidence to suggest that naps cause or increase the risk of diabetes.

Study finds link between long naps and diabetes
The problem is with long naps
Research results revealed an association between prolonged daytime naps lasting more than 60 minutes and a 45% increase in the risk of developing type 2 diabetes.
However, there was no correlation between naps of less than 40 minutes and the risk of diabetes.
Scientists have pointed out that prolonged naps may be a reflection of nighttime sleep disturbances, potentially related to sleep apnea.
These sleep disorders, in turn, can increase the risk of cardiovascular problems, including heart attacks, strokes and, consequently, type 2 diabetes.
Additionally, sleep deprivation can also result in increased appetite, contributing to the risk of type 2 diabetes.
However, researchers considered that less healthy people or those in the early stages of diabetes may be more likely to take longer naps during the day.
According to the study authors, it’s likely that the risk factors that lead to diabetes also cause napping.
This can include slightly elevated sugar levels, which means napping could be an early warning sign of diabetes.
What are the symptoms of diabetes?
- Increased thirst and frequent urination (polydipsia and polyuria)
- Constant hunger (polyphagia)
- Unexplained weight loss
- Fatigue and weakness
- Blurred or cloudy vision
- Frequent infections, such as urinary and skin infections
- Slow wound healing
