Introduction

Up to 75% of cancer patients experience sleep problems, a difficulty often amplified by chemotherapy and the debilitating side effect known as Cancer-Related Fatigue (Yarosh eta al.,2024). This isn't just normal tiredness; it's a persistent, overwhelming exhaustion that doesn't improve with rest. Fortunately, by implementing a targeted set of sleep hygiene strategies, your personalised Chemotherapy Sleep Toolkit, you can reclaim your night's rest and dramatically improve your energy during the day.

Here are 7 proven bedtime habits recommended by sleep specialists and oncologists to help you get the restorative sleep your body needs to heal.

1. Master Your Sleep Schedule

During treatment, it’s easy to let your schedule slip, going to bed late and sleeping in. This is one of the biggest disruptors of your circadian rhythm, your body's internal clock.

• The Habit: Go to bed and wake up at the exact same time every day, including weekends. Aim for a consistent 20 minute window.

• Why It Works for Chemo Patients: Chemotherapy can already alter your body's natural hormone cycles (like melatonin and cortisol). A strict schedule helps retrain your internal clock, which is crucial for maximizing your body's natural sleep and repair hormones.

2. Set the "Stimulus Control" Rule (Bedroom for Sleep Only)

If you spend too much time awake in bed, worrying, watching TV, or scrolling, your brain starts associating your bed with frustration and alertness, not rest. This is called stimulus control.

• The Habit: Reserve your bedroom only for sleep and sex. Remove all work, reading material (unless very dull), and screens.

• The Emergency Exit Strategy: If you are awake for more than 20 minutes, get out of bed! Go to another room, keep the lights dim, and do a quiet, non-stimulating activity (like listening to an audiobook or gentle stretching). Only return to bed when you feel genuinely sleepy again.

3. The 4-Hour Stimulant Ban (Watch What You Consume)

Many common substances interfere with your ability to initiate and maintain sleep, especially when your body is already under stress from chemotherapy.

• The Habit: Avoid caffeine (coffee, tea, chocolate, soda, and some pain relievers) and nicotine for at least 4 to 6 hours before bedtime. Limit alcohol entirely, as it fragments sleep even if it initially makes you drowsy.

• The Snack Rule: Do not go to bed hungry or overly full. A light, healthy, protein-rich snack (like a few almonds or half a banana) is ideal.

4. Curate Your Sanctuary (The Ideal Environment)

A perfect sleep environment is not a luxury; it's a necessary component of sleep therapy, especially when dealing with hot flashes or night sweats.

• The Habit: Maintain a room that is Cool, Dark, and Quiet. Aim for a slightly lower temperature Use blackout curtains and consider a white noise machine or earplugs.

• Pro Tip for Hot Flashes: Choose breathable, moisture-wicking bedding and pajamas. Keep an ice pack or a glass of cold water nearby.

5. Rethink the Nap (Short & Strategic)

Daytime fatigue is a core component of CRF, making naps feel essential. However, long or late naps can "steal" sleep from the night.

• The Habit: If you must nap, keep it short ($\le 30$ minutes) and early (before 3:00 p.m.). This allows you to recharge without interfering with your ability to fall asleep at night.

• CRF Strategy: Instead of sleeping, try short rest breaks throughout the day—sitting quietly with your eyes closed, rather than entering deep sleep.

6. Power Down Your Brain (The Wind-Down Hour)

You cannot go from a stressful activity to deep sleep instantly. You need a buffer zone to quiet the mental stress that often accompanies cancer treatment.

• The Habit: Create a 60-minute "Power Down" ritual. Absolutely avoid bright screens (phones, tablets, TV) because the blue light suppresses melatonin production.

• Relaxation Techniques: Focus on activities that activate your parasympathetic nervous system (rest and digest):

  • Gentle stretching or restorative yoga.

  • A warm bath or shower.

  • Deep belly breathing exercises.

  • Listening to a calming guided meditation or audio track.

7. Move Your Body (Activity Fuels Rest)

While you may feel exhausted, light physical activity during the day is one of the most effective non-drug interventions for both CRF and insomnia.

• The Habit: Get some form of movement or exercise daily, even if it’s just a 15-minute gentle walk or light stretching.

• The Timing Rule: Finish any moderate or vigorous exercise at least 3 hours before bedtime. Exercising too close to sleep can raise your core body temperature and alertness, making it harder to drift off.

When to Talk to Your Oncology Team

Sleep hygiene is the foundation, but it is not a cure-all. If you have consistently poor sleep for more than a few weeks, and it is impacting your quality of life, it's time to speak to your oncology team.

Your doctor needs to know about your insomnia, as it can be a side effect of medications (like steroids), uncontrolled pain, or a symptom of depression/anxiety. They may recommend:

• Medication Adjustments: Timing certain drugs earlier in the day.

• CBT-I (Cognitive Behavioral Therapy for Insomnia): Considered the gold standard long-term treatment for chronic insomnia, often more effective than sleeping pills alone.

• Pain Management: Ensuring your pain is controlled throughout the night.

You deserve restorative rest. By integrating these 7 proven habits into your daily life, you are giving your body the best possible chance to recover, repair, and fight.
