Question

Describe the body's typical state during the first stage of sleep.

Answer 1

Stage 1 is light sleep where you drift in and out of sleep and can be awakened easily. In this stage, the eyes move slowly and muscle activity slows. During this stage, many people experience sudden muscle contractions preceded by a sensation of falling.

Answer 2

Most people believe that sleeping is an activity that we reach once we close our eyes. But, the truth is that sleeping has 5 stages.

The first stage of sleep is the light stage, which last between 5 and 10 minutes. During this stage, the brain and body begin to slow down, to relax, but we aren't completely unconscious yet, so it's easy to wake up during this first stage.

A specific characteristic is that eyes movement slows down during this stage, because the brain is still active but starting to relax, which gives a transitional stage to the next one. Also, during this stage, the muscle tend to pull, and the hippocampus is alert to whatever is happening outside, this is the primitive brain which functioned as guard during primitive eras.
