1. Alzheimer's Disease: A study tracking 1400 participants over 14 years found a bidirectional relationship between afternoon napping and brain aging. Individuals napping for over 1 hour faced a 40% higher risk of Alzheimer's disease compared to those napping less than 1 hour.
2. Type 2 Diabetes: Research indicates a 31% increased risk of type 2 diabetes for those napping for more than 1 hour daily. Elevated blood sugar levels may also contribute to prolonged napping, suggesting that excessive nap duration could serve as an early warning sign of diabetes.
