The Healing Power of Breath.

I am undergoing my own cancer journey, and I hope sharing some of the things I do help others in their fight against this as well.

I find that I have days when I feel “down” and just want to cut myself off from the world, stay in bed and generally feel sorry for myself. One thing that works for me is practicing my breathing techniques which calm me down.

5 Simple Breathing Exercises for Stress Relief and Cancer Support

When facing cancer, whether it’s active treatment, recovery, or simply living with the uncertainty of it all, one of the most underestimated tools for healing and well-being is something you already have: your breath.

Breathing exercises are simple, free, and scientifically proven to help reduce stress, lower anxiety, improve oxygenation, and even support immune function, key elements in cancer care.

In this blog, we’ll explore the science of how breathing impacts your health during cancer treatment and share five beginner-friendly exercises you can start today.

Understanding the Science

How Breathing Helps in Cancer Treatment

Breathing is not just a mechanical act. Conscious, controlled breathing taps into the parasympathetic nervous system, also known as the “rest and digest” mode. This counters the body’s fight-or-flight response, which is often in overdrive during illness.

A 2014 study published in Psycho-Oncology found that cancer patients who practiced mindful breathing and meditation had significantly reduced anxiety and depressive symptoms compared to control groups. Another study in Integrative Cancer Therapies (2017) concluded that slow, deep breathing improved quality of life and reduced fatigue in breast cancer patients undergoing chemotherapy. Furthermore, a 2021 paper in Frontiers in Psychology demonstrated how breathing exercises helped regulate inflammatory markers, such as cytokines, which are often elevated during cancer treatment.

These findings suggest that breathing isn’t just about calming the mind—it actively supports the body’s internal healing mechanisms.

Benefits of Breathing Exercises for People Living with Cancer

  • Reduces anxiety and fear
    Regulated breathing helps you stay calm and centered in moments of uncertainty.
  • Improves sleep quality
    Deep breathing before bed can reduce insomnia—a common side effect during cancer treatment.
  • Supports immune function
    Deep breathing reduces stress-induced inflammation, which can help the body fight off illness more effectively.
  • Improves oxygen delivery
    Optimal breathing enhances oxygen supply to tissues, vital during healing and recovery.
  • Enhances digestion and detoxification
    Activating the parasympathetic system aids digestion and liver function, both critical in managing chemotherapy side effects.

How to Build a Breathing Practice

Consistency is key. Try starting with one of the above exercises each morning or before bed. Even 5 minutes a day can make a difference. You can also use breathing as a “reset button” throughout the day when anxiety, fatigue, or fear creep in. Set reminders, pair it with music, or integrate it into meditation.

In a time when so much feels uncertain, your breath is your anchor, a reminder that healing happens one inhale, one exhale at a time.
