What change occurs as you pass through NREM stages of sleep?

As you progress through the NREM stages of sleep, your body undergoes several physiological changes. These include a gradual decrease in brain wave frequency, transitioning from lighter sleep (stage 1) to deeper sleep (stages 2 and 3). Heart rate and breathing slow down, while muscle activity decreases, promoting physical restoration. Additionally, the body experiences a drop in temperature and a shift in hormone production, which are crucial for overall health and recovery.
