Summary

This study looks at what happens when people sleep only a few hours on weekdays but catch up on weekends. Researchers want to see if this pattern harms blood sugar, blood pressure, and body fat compared to getting enough sleep every night. The study involves 72 adults aged 18 to 49 who are healthy and normal weight or slightly overweight.
