Questions: Submit Recent Literature Which of the following statements correctly describes NREM sleep? □ Human growth hormone is released during NREM sleep. □ About 75 percent of adult sleep time is spent in NREM sleep. □ Muscles remain paralyzed during NREM sleep. □ NREM sleep typically occurs in the second half of the night. Select all that apply. Part C: L.O. 3: Explain the Processes of Sleep, Including the Two Stages of Sleep and Their Characteristics; Rhythm, and Sleep Wake Cycle, as Well as How They Work and Their Importance for Health

The correct answers are:

□ Human growth hormone is released during NREM sleep. □ About 75 percent of adult sleep time is spent in NREM sleep.

Explanation for each option:

1. Human growth hormone is released during NREM sleep.

   • This statement is correct. Human growth hormone (HGH) is primarily released during deep sleep, which is part of NREM (Non-Rapid Eye Movement) sleep, particularly during stages 3 and 4.

2. About 75 percent of adult sleep time is spent in NREM sleep.

   • This statement is correct. On average, about 75-80% of an adult's sleep cycle is spent in NREM sleep, which includes stages 1 through 4.

3. Muscles remain paralyzed during NREM sleep.

   • This statement is incorrect. Muscle paralysis is a characteristic of REM (Rapid Eye Movement) sleep, not NREM sleep. During NREM sleep, muscles are generally relaxed but not paralyzed.

4. NREM sleep typically occurs in the second half of the night.

   • This statement is incorrect. NREM sleep is more prevalent in the first half of the night, while REM sleep becomes more frequent in the second half of the night.

Summary: The correct statements describing NREM sleep are that human growth hormone is released during NREM sleep and that about 75 percent of adult sleep time is spent in NREM sleep.
