Five Stages Of Sleep

Electrical activity in the brain recorded during sleep

1. Light sleep: Muscles relax, body temperature drops, you drift in and out of wakefulness. Fragmented images may appear.

2. Transition: Heart rate, breathing and waves of electrical activity in the brain slow down

3. Deep Sleep: Large, slow waves in the brain.

4. The body becomes harder to awaken as it closes itself off to stimuli. In the fourth stage the waves are similar, but slower.
