Question

Infant sleep is characterized by _______ sleep cycles than those of adults, with proportionally more _______ sleep.

a. deeper; stage 1
b. shorter; REM
c. longer; stage 2
d. longer; stage 3

Answer 1

The correct answer is letter B

Usually when you are sleeping, you start at stage 1 and go through each step until you reach REM sleep. The cycle restarts every 90-110 minutes. Your brain acts differently at each stage. In some steps your body moves, while in others you remain completely still.
