The relationship between cancer and sleep
Cancer and sleep are intricately connected in ways that significantly impact both the quality of life and overall health outcomes for those affected by the disease. Sleep is a crucial physiological process that allows the body to repair, restore, and regenerate. However, cancer and its treatments can severely disrupt sleep patterns, leading to a vicious cycle where poor sleep may exacerbate the symptoms of cancer, weaken the immune system, and negatively affect treatment outcomes.
Understanding this relationship is vital for patients, caregivers, and healthcare providers in order to manage the symptoms of cancer more effectively and improve the quality of life for those battling the disease.

The importance of sleep
Sleep plays a vital role in maintaining overall health, particularly for individuals fighting cancer. During sleep, the body undergoes various restorative processes, including the repair of tissues, the strengthening of the immune system, and the regulation of hormones that control stress and inflammation. Adequate sleep is essential for mental and emotional well-being, helping to manage the psychological toll that cancer can take on patients.
Physical Restoration
Sleep is when the body repairs tissues and cells, which is particularly important for cancer patients who are undergoing treatments like chemotherapy or radiation. These treatments can cause significant damage to healthy cells, and sleep is crucial for the recovery and regeneration of these cells.
Immune System Support
A strong immune system is essential for fighting cancer, and sleep is integral to maintaining immune function. Chronic sleep deprivation can lead to a weakened immune response, making it harder for the body to combat cancer cells and increasing the risk of infections.
Mental Health and Emotional Well-being
The psychological impact of a cancer diagnosis can be profound, leading to stress, anxiety, and depression. Sleep is closely linked to mental health, with adequate sleep helping to regulate mood and reduce stress. Conversely, sleep disturbances can exacerbate mental health issues, creating a cycle of anxiety and insomnia that further depletes the body's resources.
Hormonal Balance
Sleep helps regulate hormones that control stress (cortisol) and appetite (ghrelin and leptin). Disrupted sleep can lead to hormonal imbalances that may increase stress and contribute to weight gain, which can be particularly detrimental for cancer patients trying to maintain a healthy weight during treatment.

Improving sleep quality for cancer patients
Sleep is a critical component of overall health, especially for cancer patients who often face numerous challenges that can disrupt their sleep patterns. Improving sleep quality can significantly enhance the physical and emotional well-being of those undergoing cancer treatment, helping them to better cope with the disease and its side effects. There are a variety of strategies and interventions available that can help manage sleep issues, which are commonly reported by cancer patients. This guide explores several approaches, offering a detailed overview of how to improve sleep quality in the context of cancer care.
Best practices for better sleep
Sleep challenges can vary widely among cancer patients, depending on the type of cancer, the stage of the disease, and the specific treatments being administered. These challenges can manifest as difficulty falling asleep, staying asleep, or waking up too early. The first step in improving sleep is to discuss any symptoms or issues with your healthcare team. They can help identify the root causes of your sleep disturbances and may refer you to a sleep specialist for further evaluation and treatment. Personalized care is essential, as each patient’s situation is unique.
Consulting Your Healthcare Team
Your healthcare team plays a pivotal role in managing your sleep issues. They can assess whether your sleep disturbances are related to pain, side effects of treatment, or other medical conditions. In some cases, they may recommend a sleep study to diagnose specific sleep disorders such as sleep apnea or restless leg syndrome. Depending on the findings, a tailored treatment plan can be developed to address your sleep problems effectively.
The Role of a Sleep Specialist
If your sleep issues are complex or persist despite initial interventions, a referral to a sleep specialist may be necessary. A sleep specialist can conduct a comprehensive evaluation, which might include monitoring your sleep patterns, assessing your sleep environment, and identifying any underlying sleep disorders. They can then provide targeted therapies and interventions designed to improve sleep quality, tailored specifically to your needs as a cancer.

Strategies to manage cancer-related sleep problems
Cancer patients often need to combine multiple strategies to manage sleep issues effectively. Below are some common approaches that have been found to be beneficial.
Therapy
Therapy can be an effective way to address the psychological factors that contribute to sleep disturbances. Cognitive Behavioral Therapy for Insomnia (CBT-I) is a particularly effective method, focusing on identifying and changing negative thought patterns and behaviors that affect sleep. Therapy helps reduce the anxiety and stress associated with sleep problems, making it easier to establish healthy sleep habits.
Cognitive Behavioral Therapy (CBT-I)
This is a structured program that helps patients develop better sleep habits and eliminate the anxieties that prevent sleep. Techniques include stimulus control, sleep restriction, and cognitive restructuring, which involve changing the negative thoughts related to sleep.
Counseling and Support Groups
Participating in counseling sessions or support groups can provide emotional support, which is crucial for managing the stress and anxiety that often accompany a cancer diagnosis. Sharing experiences with others who understand your struggles can be both comforting and empowering, leading to improved mental health and better sleep.
"Cognitive behavioral therapy is the gold standard for treating insomnia (CBT-i). A component of CBT-i is actually the unhelpful thoughts that a lot of times keep you up at night or even unhelpful thoughts about sleep, so we want to address those thoughts. And we do that by using the CBT model. That has a lot to do with first identifying your unhelpful thoughts and then challenging them and coming up with alternate, more helpful thinking patterns."

Relaxation techniques to help sleep
Relaxation techniques are powerful tools for calming both the mind and body, making it easier to drift into sleep and stay asleep throughout the night. These methods can also help you return to sleep if you wake up during the night.
Focused Breathing
low, deep breathing can help lower heart rate and blood pressure, promoting a state of relaxation that is conducive to sleep. Techniques like the 4-7-8 breathing method can be particularly effective.
Meditation
Mindfulness meditation involves focusing on the present moment and letting go of worries and stress. Regular practice can reduce insomnia and improve sleep quality by calming the mind.
Progressive Muscle Relaxation (PMR)
PMR involves tensing and then slowly releasing each muscle group in the body. This technique helps to release physical tension and encourages relaxation.
Music Therapy
Listening to calming music before bed can create a relaxing atmosphere, making it easier to fall asleep. Studies have shown that certain types of music can slow down the heartbeat and breathing, preparing the body for sleep.
Hypnosis and Guided Imagery
Hypnosis and guided imagery are techniques that involve focusing the mind on peaceful and relaxing images or scenarios, which can help ease anxiety and promote sleep.
"Create a great sleep routine for yourself that allows you to come back to the present and calm down. I recommend avoiding screens at least 30 mins before sleep as well so that your body can start to understand it’s time to wind down from the day."

The role of medication in sleep
Medications can be both a cause and a solution for sleep problems in cancer patients. It’s crucial to work closely with your healthcare team to ensure that your medication regimen supports good sleep rather than disrupting it.
Sleep Aids
In some cases, your doctor may prescribe sleep aids or recommend over-the-counter options. These should be used under strict medical supervision to avoid dependency or interactions with cancer treatments.
Reviewing Current Medications
Some medications commonly used in cancer treatment, such as steroids or certain pain relievers, can cause sleep disturbances. It’s important to discuss all medications with your healthcare provider, including those taken for other conditions, to ensure they are not contributing to sleep problems.
Adjusting Dosages and Timing
Sometimes, simply adjusting the dosage or timing of your medication can improve sleep. For example, taking certain medications earlier in the day rather than at night can help minimize their impact on your sleep.
Treating side effects of cancer and its treatment
The side effects of cancer and its treatments are often significant contributors to sleep problems. Addressing these side effects can, therefore, lead to better sleep.
Pain Management
Pain is a common cause of insomnia in cancer patients. Effective pain management, through medications or other therapies, is crucial for improving sleep.
Managing Nausea and Vomiting
These are common side effects of chemotherapy and can disrupt sleep. Anti-nausea medications or dietary adjustments may help reduce these symptoms.
Dealing with Fatigue
Cancer-related fatigue is different from regular tiredness and often does not improve with rest. Managing fatigue through energy-conserving techniques and addressing its underlying causes can improve sleep quality.
Dietary considerations
What you eat and drink, especially in the hours leading up to bedtime, can have a significant impact on your sleep quality. Making mindful dietary choices can help promote better sleep.
Avoid Large Evening Meals
Eating a large meal close to bedtime can cause discomfort and indigestion, making it harder to fall asleep. Aim to have your last substantial meal at least three to four hours before going to bed.
Opt for Light Snacks
If you need to eat before bed, choose a light snack that contains a mix of protein and carbohydrates. A small piece of cheese, a handful of nuts, or a slice of whole-grain toast with peanut butter are good options.
Choose Warm, Caffeine-Free Beverages
A warm, non-caffeinated drink like herbal tea or warm milk can be soothing and help signal to your body that it’s time to sleep. Avoid caffeinated drinks in the evening, as caffeine can stay in your system for several hours and disrupt sleep.

Creating a sleep-conductive environment
The environment in which you sleep plays a crucial role in the quality of your rest. Making your bedroom a place that promotes sleep can significantly improve your ability to fall and stay asleep.
Comfortable Bedding
Ensure that your mattress and pillows are comfortable and supportive. This is especially important for cancer patients who may experience pain or discomfort.
Control Light and Noise
Make your bedroom as dark and quiet as possible. Consider using blackout curtains, earplugs, or a white noise machine to create a peaceful sleeping environment.
Temperature Control
Keep your bedroom at a comfortable temperature. A cool room is generally better for sleep, as it helps the body cool down, which is necessary for sleep initiation.
Limit Screen Time
The blue light emitted by phones, tablets, and computers can interfere with the production of melatonin, a hormone that regulates sleep. Try to avoid screens for at least an hour before bedtime.
Remember, every patient’s journey is unique, and it’s important to tailor strategies to meet your individual needs. With the right approach, better sleep is within reach, helping you to feel more refreshed, energized, and ready to tackle each day.
Improving sleep quality is essential for cancer patients to maintain both physical and emotional well-being. Addressing the underlying causes of sleep disturbances, whether they are related to pain, treatment side effects, or emotional stress, is key to finding effective solutions. By consulting with your healthcare team, exploring relaxation techniques, adjusting medications, and creating a supportive sleep environment, you can significantly enhance your ability to rest and recover.

How cancer affects sleep
Cancer and its treatments can have a profound impact on sleep quality, leading to a range of sleep disorders and disruptions. These disturbances can be caused by the cancer itself, the side effects of treatment, or the psychological stress associated with the disease.
Pain and Discomfort
Pain is one of the most common reasons cancer patients experience sleep disturbances. Whether it’s due to the cancer itself, surgery, or the side effects of treatment, pain can make it difficult to fall asleep or stay asleep. Chronic pain can lead to insomnia, which in turn can worsen fatigue and reduce the body’s ability to heal.
Side Effects of Treatment
Chemotherapy, radiation therapy, and other cancer treatments can cause a variety of side effects that interfere with sleep. Nausea, vomiting, hot flashes, night sweats, and an increased need to urinate are just a few of the symptoms that can disrupt sleep. Additionally, certain medications used to treat cancer or its symptoms, such as steroids, can cause insomnia or restless sleep.
Psychological Factors
The emotional toll of a cancer diagnosis can lead to significant stress, anxiety, and depression, all of which can contribute to sleep problems. Worry about the future, fear of death, and the stress of undergoing treatment can keep patients awake at night, leading to chronic sleep deprivation.
Sleep Disorders
Cancer patients are at an increased risk of developing sleep disorders such as insomnia, restless leg syndrome, and sleep apnea. Insomnia may be triggered by the anxiety and stress associated with cancer, while sleep apnea can be exacerbated by certain treatments or by the cancer itself, particularly in cases where tumors affect the respiratory system.
Fatigue
While fatigue and sleep are closely related, cancer-related fatigue is a unique condition that does not always improve with rest. Many cancer patients report feeling exhausted even after a full night's sleep. This type of fatigue can be debilitating and is often exacerbated by sleep disturbances, creating a cycle that is difficult to break.
“Sleep is usually disrupted during treatments and can continue to be affected even after cancer. When you are sleep deprived inflammation and cortisol levels rise, which can lead to insulin resistance and weight gain which can be huge factors for cancer. According to a 2004 study, up to 80% of people affected by cancer are affected by fatigue and/or insomnia, which can impact the cells of the immune system.”

Common types of sleep problems you might experience
Insomnia
Insomnia refers to difficulty falling asleep or staying asleep. It can be short-term (lasting a single night, a few days, or weeks) or chronic (lasting three months or longer).
Hypersomnia
Hypersomnia is characterized by excessive daytime sleepiness or the need for prolonged sleep at night. Symptoms include:
-
Sleeping for 10 or more hours at a stretch (or more than 12 hours for children)
-
Longer periods of deep sleep than usual
-
Difficulty staying awake during the day
-
Persistent sleepiness that doesn’t improve after sleeping or napping
Restless Legs Syndrome
Restless legs syndrome (RLS) creates an urge to move your legs when trying to rest or sleep. Your legs may feel itchy or irritated, often causing jerking movements that disrupt sleep. RLS tends to occur more in the evening and can affect those without cancer, though it sometimes develops during chemotherapy.
Sleep Apnea
Sleep apnea involves brief pauses in breathing during sleep, with each pause lasting up to ten seconds and occurring multiple times throughout the night. Many with sleep apnea snore and frequently wake up during the night. This condition can prevent restful sleep, leading to daytime tiredness or sleepiness.
Cancer and its treatments can significantly impact sleep, leading to a range of sleep disorders and disturbances that affect both physical and mental well-being. Pain, treatment side effects, and psychological stress can all contribute to disrupted sleep, which in turn can worsen fatigue and hinder recovery. Addressing sleep issues is essential for improving quality of life and supporting the healing process during and after treatment.
If you're struggling with sleep, it's important to reach out to your healthcare team. They can help identify the underlying causes and suggest strategies to manage sleep disturbances. Whether it's through managing pain, adjusting treatment side effects, or addressing emotional health, taking steps toward better sleep can have a positive impact on both your physical health and mental clarity.
Addressing sleeping issues with complementary approaches such as relaxation techniques and therapy are also proven to be effective in managing trouble sleeping during and after cancer. Here at The After Cancer, we help cancer patients and cancer survivors learn and develop personalized strategies to build their own sleep routine and reach a good night sleep.

Long-term sleep management after cancer
After surviving cancer, many patients continue to experience sleep disturbances that can persist long after treatment has ended. The body and mind undergo significant stress during cancer treatment, and this can lead to long-term changes in sleep patterns. Managing sleep in the post-cancer phase is crucial for recovery, maintaining a good quality of life, and reducing the risk of recurrence. Long-term sleep management strategies should be personalized and adaptable to address the unique challenges faced by cancer survivors.
Post-chemotherapy sleep strategies
1. Establish a Consistent Sleep Schedule
After chemotherapy, it is important to reestablish a regular sleep-wake cycle. Going to bed and waking up at the same time every day helps regulate your body’s internal clock, making it easier to fall asleep and wake up naturally. This consistency can be challenging after the erratic schedules often experienced during treatment but is key to restoring normal sleep patterns.
2. Address Lingering Side Effects
Some side effects of chemotherapy, such as peripheral neuropathy (nerve damage), hot flashes, or hormonal imbalances, can persist and affect sleep. Managing these ongoing symptoms through medication, physical therapy, or lifestyle changes can help improve sleep quality. For example, using cooling techniques for hot flashes or wearing supportive footwear for neuropathy can reduce discomfort at night.
3. Mind-Body Therapies
Techniques such as yoga, tai chi, or mindfulness meditation can be particularly beneficial in managing post-chemotherapy sleep disturbances. These practices not only help reduce stress and anxiety, which are common after cancer treatment, but they also promote relaxation and improve sleep quality. Regular practice of these mind-body therapies can help reestablish a sense of normalcy and calm, which is conducive to better sleep.
4. Nutritional Adjustments
Chemotherapy can alter appetite and digestion, which can indirectly affect sleep. Focusing on a balanced diet that supports recovery is crucial. Incorporate foods rich in antioxidants, vitamins, and minerals to help repair the body. Avoiding caffeine and sugar, especially in the late afternoon and evening, can help prevent sleep disruptions.
5. Physical Activity
Gradual reintroduction of physical activity can aid in improving sleep post-chemotherapy. Exercise helps reduce fatigue, improves mood, and enhances sleep quality. Even low-impact activities like walking, swimming, or light stretching can make a significant difference in how well you sleep. However, it's important to listen to your body and avoid overexertion, which could lead to increased fatigue.
"What could your nighttime routine look like? Maybe it's 20 minutes of getting ready (brushing teeth, washing face, etc.), 30 minutes of reading and a 10 minute meditation before you fall asleep. Whatever that is for you, prioritize it as much as you can, even on the nights you don’t want to."
Maddy Pollack

Recovery and rebuilding strength
1. Gradual reintegration of routine
Rebuilding strength after cancer treatment involves slowly reintegrating daily activities and routines. Start with simple tasks and gradually increase activity levels as your strength returns. Prioritize rest and avoid overloading your schedule, as too much activity too soon can lead to burnout and further disrupt sleep.
2. Focused nutritional support
Proper nutrition plays a critical role in recovery and strength-building. Focus on a diet rich in proteins, healthy fats, and whole grains to support muscle repair and energy levels. Hydration is also important, but be mindful of fluid intake close to bedtime to avoid disruptions in sleep.
3. Physical Rehabilitation Programs
Engaging in a physical rehabilitation program can be beneficial for regaining strength and improving sleep. These programs, often supervised by physiotherapists, can provide structured exercises tailored to your specific needs. They can help improve cardiovascular health, build muscle, and enhance flexibility, all of which contribute to better sleep.
4. Mental Health support
Emotional recovery is just as important as physical recovery. The psychological impact of surviving cancer can linger, leading to anxiety, depression, or PTSD, all of which can disrupt sleep. Regular mental health check-ins with a therapist or counselor can help address these issues, providing coping strategies that support both mental health and sleep.
5. Sleep hygiene practices
Continuing to practice good sleep hygiene is crucial for long-term recovery. This includes creating a sleep-friendly environment, limiting screen time before bed, and avoiding stimulants. Over time, these practices can help reinforce healthy sleep patterns, which are essential for maintaining strength and overall health post-cancer.
Managing sleep issues over the long term requires patience, consistency, and the right strategies tailored to your individual needs. Whether it's adjusting your daily routine, seeking professional guidance, or trying relaxation techniques, small changes can lead to significant improvements in your sleep quality.
Remember, good sleep is vital not just for your physical health, but for your emotional and mental well-being. As you continue to implement these strategies, be kind to yourself and take one step at a time. While the journey to better sleep may take time, each effort you make is an important step toward improving your quality of life and feeling more refreshed each day.
