Sleep Problems

Sleep problems include any change in your usual sleeping habits. It could mean you need to sleep more than usual or you might have trouble sleeping, such as having trouble falling or staying asleep.

Sleeping well is important for your physical and mental health. A good night’s sleep not only helps you to think clearly, it also lowers your blood pressure, helps your appetite, and strengthens your immune system.

As many as half of all cancer patients have sleep-related problems.

Unfortunately, sleep problems are common among people being treated for cancer. These problems may be caused by painanxiety, worry, depressionnight sweats, or the side effects of treatment. See the following tips for healthy sleep and talk with your health care team if you have difficulty sleeping so you can get the help you need.

Signs of Sleep Problems

Common signs of sleep problems include:

  • Having trouble falling asleep.
  • Waking up often during the night.
  • Waking up early in the morning and not falling back to sleep.
  • Not feeling rested or still feeling tired after sleeping.

Tips for Healthy Sleep

Work with your health care team to develop a plan to help you sleep well again, and follow these steps to improve your sleep health. Check out this fact sheet and try some of the following tips.

Plan Time to Rest

Take short naps (less than 1 hour) during the day if you are tired. But don’t overdo it. Too much sleep during the day can make it difficult to sleep at night.

Keep a Regular Routine

  • Set a routine for going to bed and getting up.
  • Avoid caffeine for 6 to 8 hours before you go to bed.
  • Exercise at least once a day, no closer than 2 to 3 hours before bedtime.
  • Drink warm, caffeine-free drinks, such as warm milk or decaf tea, before bedtime.
  • Get other tips to help you manage sleep problems.


Talk to Your Health Care Team

  • Tell your doctor if you’re having sleep trouble. Feeling tired too much could be a side effect of your medication. If you’re having trouble falling asleep, a mental health professional could help you find out why and what to do.
  • Consider using cognitive behavioral therapy (CBT) and relaxation therapies to help you sleep better. For example, a CBT therapist can help you learn to change negative thoughts and beliefs about sleep into positive ones.

Ask Your Caregiver for Help

  • Ask your caregiver to help you by keeping the room quiet and comfortable while you sleep, or by assisting in your bedtime routine.
  • Learn what else caregivers can do for sleep problems.
