Why 5 Hours of Sleep Can Feel Better Than 8 !!

Why You Feel Groggier After 8 Hours Than 5 Ever woken up after a full 8 hours feeling like a zombie, but felt surprisingly alert after only 5? It’s not magic—it’s math. 🧮 It comes down to Sleep Cycles. Your brain moves through stages of sleep (Light, Deep, and REM) in roughly 90-minute loops. The 90-Minute Rule: If you wake up at the end of a cycle (e.g., after 4.5 or 6 or 7.5 hours), you wake up during light sleep and feel refreshed. The "Sleep Inertia" Trap: If your alarm goes off right in the middle of a cycle (often what happens at the 8-hour mark for some), you are ripped out of Deep Sleep. This causes "sleep inertia"—that heavy, groggy feeling that can last for hours. The Adrenaline Factor: Sometimes, that "wired" feeling on 5 hours is actually a stress response. Your body pumps adrenaline and cortisol to keep you going, masking the fatigue... until you crash later. In this video, we break down: How to time your alarm to your biological clock. Why "8 hours" is a myth for many people. How to use the "90-minute rule" to wake up energized every day.
