The Importance of Sleeping Well
Key Points
- Restful sleep is critically important to healing, well-being and quality of life.
- BCCT is interested in restful sleep because research shows impacts on risk of cancer, cancer progression and survival, response to treatment, mood and pain.
- Insomnia is common, and even more so among cancer patients.
- Several lifestyle choices can impact sleep.
- BCCT advisors suggest behavioral, dietary, movement, mind-body and natural products approaches to promoting restful sleep.

Getting adequate sleep and rest is considered an essential lifestyle strategy to include in an integrative cancer care plan. Integrative cancer care specialists such as Keith Block, MD; Gary Deng, MD; Lise Alschuler, ND, FABNO; and Nasha Winters, ND, FABNO, all emphasize the importance of balancing one’s biorhythms (also called circadian rhythms) to create an internal environment that is hostile to cancer cells while also promoting healing and health. The sleep/rest/activity cycle is one of those rhythms. Dr. Deng considers sleep as one of the 6 Pillars of Good Health (the others being exercise, diet, stress management, relationships and meaning).
One study found that patients with advanced lung cancer suffering greater circadian activity/sleep cycle disruption suffer greater interference with function, greater anxiety and depression, poorer nighttime sleep, greater daytime fatigue, and poorer quality of life than comparable patients who maintain good circadian integration.
Sleep (especially sleep at night) is the time when our bodies maintain optimal functioning of our immune, cellular, metabolic and endocrine (hormonal) systems. Sleep is also important for optimal cognitive functioning. For more information about the importance of sleep, see the National Heart, Lung and Blood Institute's page: Why Is Sleep Important?

Good sleep is necessary not only for physical health, but for mental and emotional health as well. Poor sleep, or even too much sleep, is linked to many physical, mental and emotional problems:
Good sleep is necessary not only for physical health, but for mental and emotional health as well.
- Weakened immunity
- Insulin resistance

- Impaired digestion and detoxification
- Changes in gut bacterial balance
- Obesity
- Depression
- Fatigue
- Irritability
- Anxiety
- Chronic diseases including cancer
- Cognitive impairment
Melatonin, Light and Sleep
Melatonin is produced naturally by the pineal gland during the early hours of night, signaling and initiating the transition from wakefulness to sleep. Individuals who experience sleep difficulties may have disrupted melatonin production.

One factor that influences melatonin production is bright light. Such light exposure late in the evening—and especially blue-spectrum light such as from most television, computer, mobile phone and other screens—can disrupt melatonin production and delay the initiation of sleep. Reducing or even eliminating exposure to bright and blue-spectrum light in the evening may be part of a treatment plan for sleep disruptions such as delayed sleep-wake phase disorder.
During the day, melatonin production diminishes as our production of serotonin and cortisol increase. Bright light in the morning boosts serotonin and cortisol while also diminishing melatonin production, leading to greater wakefulness and setting the stage for the next evening's production of melatonin.
To optimize our natural melatonin cycles and benefits, research indicates that we should curb bright light in the evening and increase bright light exposure in the morning. Preliminary research also shows that bright light therapy in the morning can improve sleep in people with cancer.

Electromagnetic Fields and Sleep
Electromagnetic fields (EMFs) may interfere with sleep-activity cycles—your circadian rhythms. The idea is considered controversial, but some evidence shows that EMFs may affect melatonin metabolism and circadian rhythms.
Read more
- A 2017 review highlights an effect of 900-MHz and 60-Hz EMFs on melatonin metabolism and circadian rhythms..
- A 2014 review concluded that extremely low frequency magnetic fields (ELF-MF) and radio frequency electromagnetic fields possibly influence the circadian system function. A substantial number of studies demonstrated changes in melatonin and cortisol secretion and also in sleep after exposure to these fields.
- A 2013 study found that weak EMFs disrupt melatonin and change the circadian rhythm.
If EMFs from wireless devices in your home may be interfering with your sleep and circadian rhythms, turn off wireless devices and wi-fi sources an hour or so before bedtime.

Health Effects of Poor Sleep Quality
General Health
Inadequate sleep at night leads to these physical responses:
- Low levels of melatonin, a hormone naturally produced in the pineal gland that helps regulate sleep and wake cycles.
- Elevated blood cortisol levels, usually low at night but often elevated in those with chronic sleep disruption.
Chronically elevated blood cortisol and adrenaline can cause physical changes that impact health and functioning. These changes are sometimes referred to as “weathering” of the body, akin to the weathering of a flag in a consistent high wind.
Cancer
When circadian rhythms are disrupted by conditions such as night-shift work, short sleep duration, and exposure to light at night, we see increased risk of several cancers:
Cancer patients also report insomnia at twice the rate as the general population.
Cortisol, Sleep and Cancer
Read more
Cancer incidence, progression and mortality are linked to stress and disruption of the circadian (daily) rest and activity cycle. Cortisol, our primary stress hormone, helps regulate the sleep-wake cycle. Activation of the processes that produce cortisol (the hypothalamic-pituitary-adrenal (HPA) axis) can lead to arousal and sleeplessness.
Although the mechanisms are not fully understood, high cortisol levels and disrupted sleep-wake cycles are connected to these outcomes:
Cortisol in excess pushes several cancer processes forward, especially metastasis. A rise in blood cortisol in response to stress or poor sleep quality can speed up tumor growth. Cortisol suppresses immunity, which is critical in mopping up malignant cells that remain after cancer treatment.
The combination of cortisol and adrenaline increases blood glucose levels. Chronic high blood glucose episodes can be a direct or indirect mediator of the increase in tumor cell growth. Cortisol also increases insulin resistance and seems to stimulate the ability of some cancer cells to grow and metastasize.
Studies have investigated cancer outcomes related to cortisol and sleep disruption:
- Breast cancer patients who don’t have normal cortisol rhythms have less-active natural killer cells and have reduced survival compared to others.
- In adults with cardiovascular and cerebrovascular diseases, sleeping less than six hours a night was associated with almost triple the risk of cancer mortality compared with sleeping six or more hours a night.
Fortunately, improving sleep can block this cascade of effects. Sleep, and especially deep sleep, inhibits the HPA axis that produces cortisol. Further, the “sleep hormone” melatonin promotes sleep but is also a powerful antioxidant, promotes the activation of inflammation-related genes, and has other effects on the immune response. Melatonin is also instrumental in eliminating cancer cells and reducing the side effects of chemotherapy. Promoting optimal melatonin and cortisol cycles can bring many benefits.
See Melatonin, Light and Sleep on this page.
Treating the Cancer
Working against cancer growth or spread, improving survival, or working with other treatments or therapies to improve their anticancer action
Patients with metastatic colon cancer who have restful sleep between 11pm and 7am have responded better to treatment. They also function better, don’t have as many disease symptoms, and have dramatically longer survival—a 50 percent higher five-year survival rate. In one study, those with the most abnormal sleep/activity rhythms were five times more likely to die within two years after their diagnosis.
Managing Side Effects and Promoting Wellness
Managing or relieving side effects or symptoms, reducing treatment toxicity, supporting quality of life or promoting general well-being
- Disrupted sleep, which is a sign of disrupted stress hormone rhythms, seems to make side effects of chemotherapy more intense, whereas good-quality sleep and normal rhythms can minimize these side effects.
- Better quality life and less fatigue were seen in metastatic colorectal cancer patients with normal 24-hour rest/activity rhythms than those with altered rhythms
- Sleep disruption leads to increased symptoms of depression in men with prostate cancer, possibly through dysregulating the stress response.
Reducing Risk
Reducing the risk of developing cancer or the risk of recurrence
A 2014 review concluded that maintaining a regular and adequate daily amount of sleep contributes to prevention of colorectal cancer. A 2013 review reported that women and men chronically exposed to night-shift work have a 50 percent increased risk of developing colorectal cancer compared to day-shift workers. However, long sleep duration—sleeping nine or more hours per night—is also associated with an increased risk of colorectal cancer.
The Clinical Practice Guidelines Committee of the American Society of Colon and Rectal Surgeons recommends regular sleep after curative treatment of colon and rectal cancer.
Interrupted sleep caused by obstructive sleep apnea is associated with a higher risk of melanoma, pancreatic cancer and kidney cancers, but lower risk of breast, prostate or colorectal cancers.
Optimizing Your Terrain
Creating an environment within your body that does not support cancer development, growth or spread
Cytokines are proteins with a complex relationship to your immune system and sleep cycles. If your circadian rhythm is disrupted by an external change in the light-dark cycle—such as by night-shift work or staying awake late at night—your immune cells produce a heightened proinflammatory response driven in part by cytokine release..
Chronic inflammation is linked to sleep disturbance. Cancer treatment itself causes a marked increase in inflammation which can result not only in impaired sleep, but also depression, fatigue and cognitive dysfunction. Impaired sleep can then increase inflammation. Chronic inflammation is linked to higher cancer mortality.
In patients with metastatic colorectal cancer, higher levels of inflammatory cytokines were linked to disrupted rest/activity circadian rhythms. Higher cytokine levels were associated with poorer response to chronochemotherapy (chemotherapy timed by circadian rhythms), poorer survival, increased fatigue and loss of appetite.
Therapies that reduce inflammation and promote more typical sleep-activity rhythms may impact cytokine release and improve outcomes.
Sleep deprivation was associated with a significant unbalance in histone activity—important for regulation of genes—as well as oxidative stress and ongoing inflammation in animal studies.
Clinical Practice Guidelines
2009 evidence-based clinical practice guidelines for integrative oncology state: “Any of the techniques, such as relaxation, meditation, and imagery, as well as autogenic training hypnosis, self-expression, and exercise, provide specific psychological and physiologic benefits, that is, decreases in stress; improvements in sleep, mood, and pain; a decrease in stress hormones; and improvement in immunity.” Evidence also supports use of Mindfulness-Based Stress Reduction (MBSR), yoga, and psychological interventions including behavioral therapies.
Managing Insomnia
Many people in modern society now suffer from insomnia, which is marked by these symptoms:
- Difficulty falling asleep
- Early awakening
- Frequent nighttime waking and inability to get back to sleep for an hour or two
- Not feeling refreshed in the morning

Lise Alschuler, ND, FABNO, says that many factors can interfere with the quality of our 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.
Often insomnia is related to lifestyle choices and situations that take us away from our natural rhythms and that promote inactivity.
Often insomnia is related to lifestyle choices and situations that take us away from our natural rhythms and that promote inactivity:
- Overeating, or eating foods that interfere with sleep promotion, or eating late in the evening
- Staying up late and “screening”—looking at TV, computer and cell phone screens for long hours, especially late in the evening
- Overwork or nighttime work
- Chronic unmanaged stress
Neuropsychologist Michael Howard, PhD, lectures to healthcare professionals on understanding and managing sleep disorders. He advocates first determining if presenting insomnia is primary or secondary, for the causes and remedies are different:
- Primary insomnia is an independent sleep disorder and typically linked to thinking and worrying, two brain processes that prevent the activation system of the brain from responding to normal signals for sleep.
- Secondary insomnia is caused by physical or psychosocial events or issues including these:
- Shift work
- Job loss
- Divorce
- Emotional problems such as depression
- Environmental conditions such as a warm room
- Symptoms such as hot flashes, fever or pain
Secondary insomnia is far more common; the best way to manage it is to address the condition/symptom preventing quality sleep.
Immediately resorting to sleep medications for either type of insomnia is typically not optimal, as these medications are effective less than 10 percent of the time, they compromise one or more of the sleep cycles, and they come with side effects, some serious.
Of most benefit for primary insomnia are the psychological/behavioral/cognitive therapies that change thinking patterns and reduce worrying. Dr. Howard suggests the following steps for patients to manage primary insomnia:
- Practice good sleep hygiene (see the section on Balancing Sleep/Rest/Activity Biorhythms below).
- If more intervention is needed, seek professional help if the following three statements apply:
- The insomnia has lasted more than three weeks.
- It is not improving.
- It is interfering with your ability to function during the day.
- Consider working with a sleep specialist—a healthcare professional, typically in the medical or psychology fields, with specialty training in sleep medicine and sleep disorders.
- If the sleep specialist determines that primary insomnia is the problem, consider therapies/practices that deal with the thinking/worrying:
- Cognitive-behavioral therapy (CBT) and counseling
- Specific relaxation and exercise practices
- Behavioral conditioning
Integrative Therapies to Improve Sleep Quality
Balancing Sleep/Rest/Activity Biorhythms
Noted integrative cancer specialists Keith Block, M, and Lise Alschuler, ND, FABNO, suggest actions for balancing sleep, rest and activity and promoting restful sleep, including these:
- Practice good sleep hygiene:
Read more
- Keep your bedroom dark, cool and quiet.
- Exercise daily.
- Maintain a regular schedule of sleep, work, physical activity, bedtime and waking.
- Limit daytime naps to 30 minutes.
- Avoid caffeine and excessive alcohol consumption.
- Avoid strenuous exercise or heavy meals for several hours before bedtime.
- Establish a regular relaxing bedtime routine.
- Practice a calming and meditative exercise, such as yoga, in the evening.
- Ensure adequate exposure to natural light (sunlight in the day and darkness at night)
- Consider using herbs or dietary supplements if needed (see Natural Products above)
- Work in partnership with your doctor to assess and monitor hormone imbalances; this may involve lab tests.

While both conventional and complementary options are available, a 2009 review found that behavioral therapies maintain longer-term improvement in sleep quality compared to pharmaceuticals.
One behavioral adjustment—timing of bedtime—may improve sleep duration. For example, going to bed before midnight is associated with longer sleep in ovarian cancer survivors in the first six months following treatment. Further recommendations for creating a sleep environment to promote quality sleep are listed at right.
Conventional Approaches
In conventional medicine, insomnia and sleep disruption are often treated with sleep medications which may help temporarily but don’t address the underlying cause, can be habit-forming and may even increase risks of death from a variety of causes including overdose, infections, cancer, depression and suicide, hypnotic-withdrawal insomnia, and automobile crashes, falls, and other accidents.
Eating Well
A fatigue-reduction diet rich in fruit, vegetables, whole grains and omega-3 fatty acid-rich foods improved sleep and fatigue in women with breast cancer.
Reducing Hot Flashes as a Barrier to Sleep
A 2009 review concluded that “acupuncture does not appear to be more effective than sham acupuncture for treatment of vasomotor symptoms (hot flashes) in postmenopausal women in general.” However, the following evidence has come forth since that review regarding acupuncture and hot flashes:
Read more
- A study in 2015 found that electroacupuncture (EA) with breast cancer patients may be more effective in reducing hot flashes than the prescription drug gabapentin, and with fewer side effects. EA was also shown comparable to gabapentin for improving sleep quality in women experiencing hot flashes.
- Early phase studies suggest that acupuncture may relieve hot flashes in prostate cancer patients.

Access
Many of the strategies for improving sleep are available through books, websites, group classes or private lessons. If you decide to use diet and supplements to help with your sleep, consulting with a healthcare professional who is experienced in prescribing diets and supplements for cancer patients—such as an integrative oncology physician, a naturopathic oncologist, an oncology dietitian or clinical nutritionist—could be helpful.
Cautions
Mind-body approaches to helping with insomnia are generally considered safe.
If you decide to take natural products to assist with sleep, consult with your pharmacist or healthcare provider to see if any contraindications, side effects or drug-herb or herb-herb interactions arise. Let your cancer care team know if you are taking any natural products such as herbs or supplements.
