CBT-I CBT-I Sleep Hygiene & Lifestyle Factors

Question 1

In CBT-I, sleep hygiene education is considered:

Accepted Answer

A necessary but insufficient standalone treatment for chronic insomnia

Answer

Sleep hygiene alone has limited efficacy for chronic insomnia but is included as a component of comprehensive CBT-I.

Question 2

Caffeine has a half-life of approximately:

Accepted Answer

5-6 hours

Answer

Caffeine's half-life is approximately 5-6 hours, meaning a cup of coffee at noon still has half its stimulant effect at 6 PM.

Question 3

The recommended cut-off time for caffeine consumption in patients with insomnia is generally:

Accepted Answer

At least 6 hours before bed

Answer

Given caffeine's half-life, consuming caffeine at least 6 hours before bedtime minimizes its sleep-disrupting effects.

Question 4

Alcohol's effect on sleep architecture is best characterized as:

Accepted Answer

Reducing sleep onset latency but fragmenting sleep in the second half of the night

Answer

Alcohol shortens sleep onset but causes rebound arousal in the second half of the night as it is metabolized.

Question 5

The optimal bedroom temperature for sleep is approximately:

Accepted Answer

60-67°F (15-19°C)

Answer

Core body temperature must drop to initiate sleep, and a cooler bedroom (60-67°F) facilitates this process.
