Colon Cancer and Sleep Therapies

Colon cancer and sleep therapies are important topics, but are often underutilized. Meaning, while your oncologist is knowledgeable about conventional cancer therapy, such as chemo, radiation, and surgery, they may not be familiar with sleep therapy.

I am a long-term survivor of an incurable blood cancer. My oncologist never talked to me about non-conventional issues such as fatigue, sleep, pain, etc.  Sleep, or lack thereof, is one of the most talked-about issues in the online cancer groups that I frequent.

The challenge is that conventional cancer therapies can disrupt the patient’s circadian rhythm. Yet nothing is more important than sleep for managing the side effects brought on by chemo, radiaton and surgery.

So what’s a colon cancer patient to do?

The video and evidence-based sleep therapies listed below offer possible solutions to colon cancer patients and survivors struggling with sleep difficulties. The therapies below can help you normalize your circadian rhythm.

🧠 1. Cognitive Behavioral Therapy for Insomnia (CBT-I)

What it is: A structured therapeutic approach that helps change thoughts and behaviors that interfere with sleep.
Benefits: Improves sleep quality, reduces time awake after falling asleep, and may help mood and fatigue. Significant research shows it’s effective specifically for breast cancer survivors with insomnia. PubMed+1

Components often include:

• Stimulus control (associating bed with sleep)
• Sleep restriction (limiting time in bed to consolidate sleep)
• Sleep hygiene education
• Cognitive restructuring (challenging unhelpful thoughts about sleep)

Formats: Can be delivered in person, online, or via apps and guided programs.

🛏️ 2. Brief Behavioral Treatments (e.g., BBTI)

This is a shorter, nurse-delivered version of CBT-I that emphasizes behavior changes (like sleep restriction and stimulus control) and education. Studies show it improves insomnia severity and sleep quality in cancer survivors. Springer Link

🧘 3. Mind-Body and Relaxation Approaches

These can help reduce stress and promote relaxation before bedtime:

• Mindfulness-based stress reduction (MBSR) — meditation and awareness practices shown to improve sleep in cancer survivors. Wikipedia
• Yoga — gentle motion plus breath work can improve sleep quality and reduce reliance on sleep meds. CancerConnect
• Relaxation techniques — deep breathing, progressive muscle relaxation, guided imagery. Dana-Farber Cancer Institute

🏃 4. Physical Activity

Regular, moderate daytime exercise (e.g., walking, swimming) supports sleep regulation and reduces fatigue. Aim for consistent activity but avoid vigorous exercise close to bedtime. CDC+1

🛌 5. Sleep Hygiene and Routine Optimization

These are foundational practices that support all therapeutic approaches:

• Keep consistent bedtimes and wake times every day. CDC
• Make the bedroom cool, quiet, and dark. CDC
• Avoid large meals, caffeine, nicotine, and alcohol before bed. Dana-Farber Cancer Institute
• Limit daytime naps and keep them short. CDC
• Avoid screens at least an hour before bed (blue light can disrupt circadian rhythms). CDC

🗣️ 6. Psychotherapy and Counseling

Addressing anxiety, depression, or stress related to the cancer experience (fear of recurrence, PTSD-like stress) with a therapist can indirectly improve sleep. Michigan Medicine

🙌 7. Complementary & Supportive Practices

Some survivors find benefit from:

• Tai Chi or gentle Qigong — mind-body movement shown to improve insomnia. Breast360
• Meditation apps and sleep programs — guided sessions can ease the transition to sleep. Breast Cancer Now
• Consistent morning sunlight exposure — helps regulate circadian rhythms and melatonin production. CDC

⚠️ 8. Medications (When Appropriate)

Prescription sleep aids or short-term medication may sometimes be used, but these should be discussed carefully with your oncologist or sleep specialist (because of side effects, interactions with cancer treatments, or tolerance issues). Breast Cancer Now

🧩 Putting It Together

A multimodal approach often works best — combining behavioral therapy like CBT-I with improved sleep habits, physical activity, and stress-reduction strategies tailored to the individual. Start with non-pharmacological approaches first, and coordinate with your health care providers for personalized care.

Personal experience has taught me that taking a multimodal approach to fixing your sleep may be necessary. For example, I exercised only moderately during the days following my autologous stem cell transplant.  I took a nap daily but tried not to sleep too much during the day. I ate three meals a day even if I wasn’t hungry. I followed a sleep regimen when preparing for bed each night. I take low-dose melatonin and CBD oil, but only occasionally.

My point is that while getting a full night’s sleep was easy before I was diagnosed with cancer, I now have to work at it.

Have you been diagnosed with colon cancer? Are you healing from surgery or in active therapy?  Do you have a difficult time sleeping?

Sleep and Diet: Mounting Evidence of a Cyclical Relationship

Two factors intrinsic to health are diet and sleep. These two behaviors may well influence one another. Indeed, that insufficient sleep adversely impacts dietary intakes is well documented.

On the other hand, diet may influence sleep via melatonin and its biosynthesis from tryptophan. Experimental data exist indicating that provision of specific foods rich in tryptophan or melatonin can improve sleep quality. Whole diets rich in fruits, vegetables, legumes, and other sources of dietary tryptophan and melatonin have been shown to predict favorable sleep outcomes.

Although clinical trials are needed to confirm a causal impact of dietary patterns on sleep and elucidate underlying mechanisms, available data illustrate a cyclical relation between these lifestyle factors. We recommend adopting a healthful diet to improve sleep, which may further promote sustained favorable dietary practices.
