Sleep after cancer treatment
Falling asleep, staying asleep, waking early.
What is going on
Sleep problems are among the most common concerns after treatment, and they make almost everything else harder.
Behavioral approaches for insomnia have the strongest general evidence, usually before sleep medicines.
What tends to help
- Consistent wake time
- Light exposure in the morning
- Limiting alcohol close to bedtime
- Getting out of bed when awake more than 20 minutes
Questions worth asking
- Is cognitive behavioral therapy for insomnia available to me?
- Could hot flashes, pain, or medicines be waking me?
- Should I be screened for sleep apnea?
Who usually owns this
- Primary care
- Sleep medicine
- Behavioral health
Contact a clinician promptly
- Loud snoring with pauses in breathing, or falling asleep while driving
