Question

Quizplus · Accepted Answer

Most adults need seven to nine hours of sleep every night to function properly and maintain good physical and mental health. Lack of sleep can lead to a number of negative health consequences.

Option B is incorrect because during REM sleep, the brain is actually very active and many muscles throughout the body experience paralysis, but others, such as those involved in eye movement, become very active.

Option C is incorrect because while alcohol can make a person feel drowsy and fall asleep more quickly, it actually disrupts the quality and restorative properties of sleep, leading to less restful and refreshing sleep.

Option D is incorrect because an increase in total sleep time typically leads to a decrease in stress hormone levels, as sleep is an important time for the body to recover and regenerate.
