Sleep Problems

Any change in your usual sleeping habits can cause a sleep problem. People who are getting treatment for cancer may get more tired and may need to sleep more than usual. Sometimes, the opposite occurs and people have trouble sleeping. Reasons for changes in usual sleeping habits include pain, anxiety, worry, depression (see the related sections), night sweats, or the side effects of treatment or medicines.

What the patient can do

  • Sleep as much as your body tells you to, but when you’re awake, try to exercise at least once a day. Do this at least 2 to 3 hours before bedtime. (See the section called “ Exercise.”)
  • Avoid caffeine for at least 6 to 8 hours before bedtime – longer if it affects your sleep.
  • Do not drink alcohol in the evening. It can keep you awake as it “wears off.”
  • Drink warm, caffeine-free drinks, such as warm milk or decaf tea, before sleep.
  • Use a quiet setting for rest at the same time each day. Take short daytime naps if needed (less than an hour) to avoid interfering with nighttime sleep.
  • Take prescribed sleeping medicine or pain relievers at the same time each night. If pain keeps you awake, see the section called “ Pain.”
  • Have someone rub your back or massage your feet before bedtime.
  • Keep sheets clean, neatly tucked in, and as free from wrinkles as possible.
  • Talk with your cancer team about relaxation therapy or getting a referral to a hypnotherapist.

What caregivers can do

  • Help keep the room quiet and comfortable during sleep.
  • Offer gentle backrubs or foot massages near bedtime.
  • Offer a light bedtime snack.
  • Let the cancer team know if the patient seems to be confused during the night.

Call the cancer team if the patient:

  • Is confused at night
  • Can’t sleep at all at night
