The newborn sleeps about how many total hours during a 24-hour period?

A. 6 to 8 hours

B. 8 to 12 hours

C. 13 to 15 hours

D. 16 to 17 hours

Summary Introduction

Introduction:

The sleep pattern or sleep cycle involves a transition through various sleep stages. The sleep pattern changes throughout a person’s life and becomes more erratic as we progress to later stages of life. Infants have a regular sleep pattern and despite their small size, large physical and metabolic activities occur within them.

Explanation

Justification/ Explanation for the correct answer:

Option (d) is given as 16 to 17 hours. A newborn baby sleeps about 16 to 17 hours during a 24 hours period. They have a regular sleep pattern that involves an equal amount of REM and non-REM sleep. They exhibit many physical activities in a non-REM stage, such as coughing, twitching, and gurgling. They are awake only for a period of around 7-8 hours. Hence, option (d) is correct.

Explanation for the incorrect answer:

Option (a) is given as 6 to 8 hours. The sleep pattern vastly changes as we grow older and in adults, it is irregular. REM sleep is reduced from 50 percent to 20 percent. Stage N3 is also reduced greatly and is completely absent during later stages of life. Adults sleep 6 to 8 hours a day while an infant sleep about 16 to 17 hours...
