Sleep disruption at a glance

Sleep disruption, also called insomnia, can greatly impact your quality of life, but therapies are available to help you achieve quality sleep. 

Difficulty falling asleep, staying asleep, or achieving restful sleep are markers of sleep disruption. They can impact your ability to function, may worsen symptoms and side effects during cancer treatment, and may even affect your response to treatment. 

Here we discuss ways to manage and improve your sleep quality if you have trouble falling asleep or staying asleep once you’re in bed. If you have difficulty managing your daily schedule to give yourself at least seven hours in bed before you need to get up, see Sleeping Well ›.

Sleep disruption may be a symptom of stress. If stress is contributing to your sleep disruption, see our guide to Managing Stress ›.

Sleep disruption: an overview

What is sleep disruption?

Sleep disruption, also known as insomnia, is characterized by difficulty in falling asleep within a reasonable time, trouble returning to sleep after waking during the night, or an inability to get restful sleep.

Sleep disruption and cancer

Getting seven to eight hours of sleep regularly is one step you can take to improve your resilience and well-being. Adequate and quality sleep may improve your ability to manage side effects and symptoms, reduce your risk of recurrence, and possibly improve your response to treatment.

Unmanaged symptoms such as pain, depression, or anxiety can contribute to insomnia, which in turn can worsen insomnia and other cancer-related symptoms. Nearly two-thirds of people with cancer experience sleep disturbances.1Al Maqbali M, Al Sinani M et al. Prevalence of sleep disturbance in patients with cancer: a systematic review and meta-analysis. Clinical Nursing Research. 2022 Jul;31(6):1107-1123.

We review the evidence of links between sleep and cancer, and between sleep and side effects and symptoms, in Sleeping Well ›.

What can cause or trigger sleep disruption?

Many factors can interfere with the quality of sleep: “These include unresolved stress, a noisy bedroom environment, too much light in the bedroom, a bedroom that is too warm, hormonal issues such as hot flashes, too much alcohol, insufficient protein in the evening meal, and side effects of medications.”2Alschuler LN, Gazella KA. The Definitive Guide to Cancer, 3rd Edition: An Integrative Approach to Prevention, Treatment, and Healing. Berkeley, California: Celestial Arts. 2010.

Medical conditions

Many medical conditions can contribute to sleep disruption. According to the National Comprehensive Cancer Network, these include pain, emotional distress, fatigue, or alcohol and substance use; cardiac, endocrine, or respiratory disorders; anemia; and neurological problems, including neuropathy from chemotherapy.3Sanft T, Day A et al. NCCN Guidelines® Insights: Survivorship, Version 1.2023. Journal of the National Comprehensive Cancer Network. 2023 Aug;21(8):792-803. Changes in the gut microbiome have also been associated with sleep disturbance among people with cancer, but it is not clear in which direction the link operates.4Yao ZW, Zhao BC et al. Relationships of sleep disturbance, intestinal microbiota, and postoperative pain in breast cancer patients: a prospective observational study. Sleep and Breathing. 2021 Sep;25(3):1655-1664. The increased incidence of depression, inflammation, and illness among people with cancer may also be a factor in why people with cancer report insomnia at twice the rate as the general population.5Azizoddin DR, Soens MA et al. Perioperative sleep disturbance following mastectomy: a longitudinal investigation of the relationship to pain, opioid use, treatment, and psychosocial symptoms. Journal of Clinical Oncology. 2023 Feb 1;39(2):76-84; Irwin MR. Depression and insomnia in cancer: prevalence, risk factors, and effects on cancer outcomes. Current Psychiatry Reports. 2013 Nov;15(11):404. Also see our handbooks on Pain ›, Depression ›, and Anxiety ›.

Medications and therapies

Opioid pain medications (such as codeine, morphine, oxycodone, and tramadol)6Robertson JA, Purple RJ et al. Sleep disturbance in patients taking opioid medication for chronic back pain. Anaesthesia. 2016 Nov;71(11):1296-1307; Rosen IM, Aurora RN et al. & American Academy of Sleep Medicine Board of Directors. Chronic Opioid Therapy and Sleep: An American Academy of Sleep Medicine Position Statement. Journal of Clinical Sleep Medicine. 2019 Nov 15;15(11):1671-1673., antiemetics (such as dexamethasone), antihistamines, antidepressants, and antipsychotics can all contribute to sleep disruption.7Sanft T, Day A et al. NCCN Guidelines® Insights: Survivorship, Version 1.2023. Journal of the National Comprehensive Cancer Network. 2023 Aug;21(8):792-803. Check the inserts of any prescription medications you use or ask your pharmacist if you have concerns. 

Therapies that we have reviewed that may trigger sleep disruption:

Lifestyle and behavior

Insomnia is often related to lifestyle choices and situations that take us away from our natural rhythms and that promote inactivity:

  • Overeating, eating foods that interfere with sleep promotion, or eating late in the evening or at night
  • Consuming food or beverages with caffeine, including energy drinks
  • Overwork or nighttime work
  • Staying up late and looking at television, computer and/or cell phone screens for long hours, especially late in the evening
  • Chronic unmanaged stress
  • Opioid use
  • Alcohol use

Environmental factors

Certain factors in your environment can affect sleep:

Our Creating a Healing Environment › handbook includes details of the evidence regarding environmental exposures and sleep disruption, plus strategies for reducing exposures.

Top evidence-based practices and therapies for managing sleep disruption

Conventional therapies

There are many well-known medications for insomnia, including benzodiazepines such as diazepam (Valium), sedatives like eszopiclone (Lunesta), and anticonvulsants like gabapentin. These can be effective in treating short-term insomnia (2-4 weeks),12Zheng X, He Y et al. Pharmacological interventions for the treatment of insomnia: quantitative comparison of drug efficacy. Sleep Medicine. 2020 Aug;72:41-49. but if used for a longer time, they can have serious side effects, including addiction.13Momin R, Ketvertis K. Short-term insomnia. StatPearls. 17 Jul 2023. There is good evidence that melatonin and melatonin receptor agonists like ramelteon (Rozerem) can improve sleep.14Kuriyama A, Honda M, Hayashino Y. Ramelteon for the treatment of insomnia in adults: a systematic review and meta-analysis. Sleep Medicine. 2014 Apr;15(4):385-92; Zhang Q, Gao F, Zhang S, Sun W, Li Z. Prophylactic use of exogenous melatonin and melatonin receptor agonists to improve sleep and delirium in the intensive care units: a systematic review and meta-analysis of randomized controlled trials. Sleep & Breathing. 2019 Dec;23(4):1059-1070; Liu J, Wang LN. Ramelteon in the treatment of chronic insomnia: systematic review and meta-analysis. International Journal of Clinical Practice. 2012 Sep;66(9):867-73. Melatonin › has many other benefits and is one of CancerChoices’ top-rated therapies.

As many as 20% of Americans have sleep apnea, a condition where breathing stops and starts during sleep.15Franklin KA, Lindberg E. Obstructive sleep apnea is a common disorder in the population-a review on the epidemiology of sleep apnea. Journal of Thoracic Disease. 2015 Aug;7(8):1311-22. If sleep apnea is contributing to sleep disruption, a continuous positive airway pressure (CPAP) machine can help.16Shang W, Zhang Y, Wang G, Han D. Benefits of continuous positive airway pressure on glycaemic control and insulin resistance in patients with type 2 diabetes and obstructive sleep apnoea: a meta-analysis. Diabetes, Obesity and Metabolism. 2021 Feb;23(2):540-548. 

Lifestyle practices

Minimizing alcohol use

Drinking alcohol habitually is associated with worse sleep across many studies.17Zhong L, Han X et al. Modifiable dietary factors in adolescent sleep: A systematic review and meta-analysis. Sleep Medicine. 2024 Mar;115:100-108; Meneo D, Bacaro V et al. A systematic review and meta-analysis of the association between young adults’ sleep habits and substance use, with a focus on self-medication behaviours. Sleep Medicine Review. 2023 Aug;70:101792. Contrary to the belief that alcohol helps with sleep, people who drink alcohol shortly before bed have also shown worse sleep quality.18Pabon E, Greenlund IM et al. Effects of alcohol on sleep and nocturnal heart rate: Relationships to intoxication and morning-after effects. Alcohol, Clinical and Experimental Research. 2022 Oct;46(10):1875-1887; Greenlund IM, Cunningham HA et al. Morning sympathetic activity after evening binge alcohol consumption. American Journal of Physiology: Heart and Circulatory Physiology. 2021 Jan 1;320(1):H305-H315; National Comprehensive Cancer Network. Survivorship care for cancer-related late and long-term effects. 2024. For help reducing the amount of alcohol you drink, talk to your doctor or find local treatment options through the Substance Abuse and Mental Health Services Administration ›

Moving More

Exercising during the day promotes better sleep in many ways, including reducing stress and inflammation and increasing the body’s production of melatonin (a hormone that regulates sleep).19Alnawwar MA, Alraddadi MI et al. The effect of physical activity on sleep quality and sleep disorder: a systematic review. Cureus. 2023 Aug 16;15(8):e43595. People with cancer and cancer survivors who get moderate exercise have shown better sleep across many studies.20Singh B, Spence R et al. Exercise for individuals with lung cancer: a systematic review and meta-analysis of adverse events, feasibility, and effectiveness. Seminars in Oncology Nursing. 2020 Oct;36(5):151076; Wu C, Zheng Y et al. Nonpharmacological Interventions for cancer-related fatigue: a systematic review and Bayesian network meta-analysis. Worldviews on Evidence-Based Nursing. 2019 Apr;16(2):102-110; Gururaj R, Samuel SR et al. Effect of exercise based interventions on sleep and circadian rhythm in cancer survivors—a systematic review and meta-analysis. PeerJ. 2024 Mar 8;12:e17053. The kinds of gentle exercise many experts recommend for people with cancer include Tai Chi and Qigong ›, walking, and yoga ›. See 7 Lifestyle Practices: Moving More ›

Sleep hygiene

Good sleep hygiene includes these practices:21Sanft T, Day A et al. NCCN Guidelines® Insights: Survivorship, Version 1.2023. Journal of the National Comprehensive Cancer Network. 2023 Aug;21(8):792-803; National Sleep Foundation. Sleep Hygiene. Viewed November 6, 2021; Alschuler LN, Gazella KA. The Definitive Guide to Cancer, 3rd Edition: An Integrative Approach to Prevention, Treatment, and Healing. Berkeley, California: Celestial Arts. 2010; Block KI. Life Over Cancer: The Block Center Program for Integrative Cancer Care. New York: Bantam Dell. 2009. 

  • Set your sleep schedule: try to get to bed and wake up at relatively similar times each day.
  • Follow a nightly routine.
  • Avoid bright lights in the evening and night.
  • Limit screen time, heavy meals, fluid intake, alcohol, nicotine, and caffeine near bedtime. 
  • Unplug from electronics and the blue light from television, computer, and phone screens late in the evening.
  • Engage in relaxation or winding-down activities before bedtime.
  • Get exposure to daylight, especially in the morning.
  • Get physical activity.
  • Don’t dine late in the day—try to finish eating at least 3 hours before bedtime.
  • Reserve your bed for sleeping and intimacy, but not other activities such as watching television, phone conversations, or eating.
  • Make your bedroom comfortable and conducive to sleep, including keeping it dark, quiet, and not too warm, and get a comfortable bed and pillow if possible.
