CBT-I CBT-I Sleep Hygiene & Lifestyle Factors 3

Question 1

Light therapy in the context of CBT-I is primarily used to:

Accepted Answer

Adjust circadian timing in patients with circadian phase issues alongside insomnia

Answer

Light therapy is selectively used when a circadian component (e.g., delayed or advanced sleep phase) contributes to the insomnia picture.

Question 2

The term 'wind-down routine' in CBT-I refers to:

Accepted Answer

A consistent pre-sleep period of relaxing activities to signal the brain that sleep is approaching

Answer

A wind-down routine creates a consistent transition from wakefulness to sleep, reducing cognitive and physiological arousal before bed.

Question 3

Which of the following is NOT typically included in standard sleep hygiene recommendations?

Accepted Answer

Limiting time in bed to actual sleep time only

Answer

Sleep restriction is a core CBT-I behavioral component distinct from sleep hygiene; sleep hygiene does not include prescribing time-in-bed limits.

Question 4

How does social media use before bed impact sleep beyond blue light exposure?

Accepted Answer

It increases cognitive and emotional arousal through engaging content

Answer

Social media stimulates cognitive engagement, emotional responses, and social comparison, all of which increase arousal independent of light.

Question 5

The sleep-promoting effects of melatonin supplementation are most reliable for:

Accepted Answer

Shifting circadian timing and managing jet lag

Answer

Melatonin is most evidence-supported for circadian timing applications (jet lag, shift work, delayed sleep phase) rather than treating chronic insomnia's core mechanisms.
