Lesson Overview

10.1 – Sleep Cycle Science: Sleep happens in repeating cycles that help your body and mind recover so you can feel alert and strong the next day. Each cycle includes light sleep, deep sleep, and REM sleep where dreaming happens. Deep sleep repairs muscles and strengthens your immune system, while REM sleep helps memory, learning, and emotional balance. Cycling through these stages multiple times each night keeps your brain and body functioning at their best. When sleep is cut short, fewer full cycles happen, leading to low energy, slower recovery, and difficulty focusing. Understanding sleep cycles encourages you to protect enough hours for the complete process. A steady sleep schedule helps your internal clock guide when you feel tired and when you wake easily. The more consistent your routine, the better your body becomes at entering deep, restorative sleep. Quality rest supports every part of your wellness journey, from workouts to mood and motivation.
