Sleep quality and breast cancer recovery

Sleep problems are among the most common and long-lasting difficulties after breast cancer. Many people have trouble falling asleep, wake frequently during the night, wake too early, or feel unrefreshed even after a full night in bed. There are many reasons. Worry about the cancer, scans or the future can keep the mind racing. Hot flushes and night sweats from menopause or hormone therapy wake people repeatedly. Pain, stiffness after surgery, lymphedema discomfort and joint aches can make it hard to get comfortable. Steroids and some other medicines disturb sleep. Changes in daily routine, daytime napping and reduced activity during treatment can upset the body clock. Depression and anxiety are also closely linked with poor sleep. Over time, poor sleep worsens tiredness, mood, concentration, pain tolerance and quality of life. The good news is that sleep problems after cancer are treatable. Cognitive behavioural therapy for insomnia is the most effective long-term treatment and works well for cancer survivors. Other helpful approaches include regular sleep and wake times, daytime activity and light, managing hot flushes and pain, limiting caffeine and alcohol, creating a calm bedroom, and relaxation practices. Sleeping tablets can help for short periods but are not a long-term solution. Talk to your team if poor sleep persists.

Sleep problems are common

Many survivors struggle with sleep during and after treatment.

Many causes overlap

Worry, hot flushes, pain and medicines often combine.

Effective help exists

CBT for insomnia and practical changes improve sleep for most people.

Night-time worry is very common after cancer.

Schedule worry time

Set aside time earlier in the evening to write down worries and possible next steps.

Keep a notebook by the bed

Jot down thoughts that come up so you can let them go until morning.

Relaxation techniques

Slow breathing, body scans or prayer can calm the mind.

Get up if awake long

If you cannot sleep, get up and do something calm in dim light, returning to bed when sleepy.

Cognitive behavioural therapy for insomnia, often called CBT-I, is recommended as the first treatment for long-term sleep problems, including in people after breast cancer. Studies in cancer survivors show it improves sleep quality, reduces time spent awake at night and can also ease tiredness and low mood. Benefits often last long after the programme ends.

Sleep diary

You record bedtime, time to fall asleep, night waking, wake time and how rested you feel. Patterns in the diary guide the treatment plan.

Sleep window

Time in bed is limited at first to roughly the hours you actually sleep, then gradually extended as sleep becomes deeper and more continuous. This strengthens the body's natural sleep drive.

Stimulus control

You learn to use the bed only for sleep and intimacy, go to bed only when sleepy, and leave the bedroom if awake for a long time, retraining the brain to link bed with sleep.

Changing unhelpful thoughts

Thoughts like I must get eight hours or tomorrow will be ruined increase anxiety. CBT-I helps replace them with calmer, more balanced thinking.

Relaxation skills

Breathing exercises and muscle relaxation reduce tension at bedtime.

Formats and access

CBT-I is offered by trained psychologists, some hospital supportive care services and online programmes, usually over six to eight weeks.
