Sleep debt occurs when you consistently get less sleep than your body needs. While sleeping longer on weekends may temporarily reduce fatigue, it cannot fully reverse the long-term effects of chronic sleep deprivation. Poor sleep can disrupt hormones, metabolism, and cognitive function, making consistent sleep patterns essential for overall health.

Sleep plays a crucial role in regulating hormones, metabolism, and body weight. When sleep is disrupted, hormones that control hunger and stress become imbalanced, which can increase cravings, slow metabolism, and contribute to weight gain. Quality sleep also supports insulin sensitivity and energy regulation.
