One Night of Partial Sleep Loss Triggers Insulin Resistance
Can One Bad Night of Sleep Affect Your Blood Sugar the Next Day?
Yes, and the effects are immediate and measurable. This controlled study found that just one night of partial sleep deprivation (4 hours instead of 8) induced insulin resistance across multiple metabolic pathways in healthy subjects. The research demonstrates that acute sleep loss doesn’t just make you tired—it rapidly disrupts your body’s ability to process glucose effectively, creating metabolic dysfunction that can be detected within hours of sleep restriction.
