Question 2

Question 3

A client drinks coffee at 4 PM and reports trouble sleeping. What should a health coach explain about caffeine?

Accepted Answer

Caffeine has a half-life of about 5–6 hours and can delay sleep onset

Short naps of 20–30 minutes before 3 PM provide restorative benefits without causing sleep inertia or interfering with nighttime sleep drive.
