Question

which of the following is a clinical symptom of insomnia?
multiple choice
taking longer than 10 minutes to fall asleep
awakening two or more times per night
sleeping less than 6.5 hours total per night due to periods of awakening
experiencing more than 30 minutes of slow - wave sleep

Explanation:

Insomnia is characterized by difficulty falling asleep, staying asleep, or having non - restorative sleep. Taking longer than 10 minutes to fall asleep is not the strict clinical definition, and experiencing more than 30 minutes of slow - wave sleep is a normal part of sleep and not a symptom of insomnia. Sleeping less than 6.5 hours due to awakenings and awakening two or more times per night can be symptoms. However, awakening two or more times per night is a common clinical symptom of insomnia as it disrupts sleep continuity.

Answer:

awakening two or more times per night
