Understanding Sleep Stages

Sleep isn’t a uniform state. Instead, it consists of several stages that cycle throughout the night.

Stage 1: Light Sleep

This is the stage between wakefulness and sleep. During this time, you’re easily awakenable, but your heart rate and eye movements start to slow down.

Stage 2: Deep Sleep

At this stage, your heart rate slows further and your body temperature drops, preparing you for deep sleep.
