This study focuses on understanding how sleep habits affect blood sugar control and brain health, particularly in middle-aged adults who are overweight or obese. These groups are at higher risk for developing type 2 diabetes, making it essential to understand how factors like sleep duration, quality, and timing might impact their health. The study aims to fill a gap in research by exploring how overall sleep health relates to both blood sugar levels and brain function, which could lead to better health strategies for preventing diabetes and maintaining brain health. Participants will be recruited from two locations in Sweden and will have their sleep patterns monitored using a special sleep device for 14 days. Their glucose levels will be checked continuously with a small monitor, and their physical activity will be tracked with a wristband. Participants will also log their food intake and mood through a smartphone app. During this period, blood and stool samples will be collected to analyze various health markers. Additionally, participants will undergo brain scans and perform tests to assess their cognitive abilities. This comprehensive study will be repeated after a year to observe any changes over time, providing valuable insights into the long-term impacts of sleep on health.
