One Sleepless Night Ruins Weeks of Metabolism? How Sleep Deprivation Dismantles Muscle via Cortisol
Many assume the exhaustion after an all-nighter can be erased by simply sleeping in later. Yet physiological research proves that just a single night of sleep deprivation causes acute insulin resistance comparable to weeks of a high-sugar diet. This article examines the nighttime tug-of-war between growth hormone and cortisol, demonstrating how sleep deprivation impairs insulin receptors and triggers catabolic pathways that break down muscle tissue, leaving you with elevated blood sugar and eroded muscle mass.
