When Your Mind Feels Like It's Somewhere Else

If you've noticed that your thoughts seem harder to hold onto during cancer treatment — that words slip away mid-sentence, that reading a page takes three attempts, or that you walk into a room and immediately forget why — you're not imagining it, and you're far from alone.

This experience is so common it has a name: cancer-related cognitive changes, often called "chemo brain" or "cancer fog." It can show up as difficulty concentrating, problems with short-term memory, mental fatigue, slower processing, or a general sense of being mentally scattered. And while it's frequently associated with chemotherapy, it can also arise from radiotherapy, hormone therapies, surgery, disrupted sleep, emotional stress, and the sheer weight of what the body is navigating.

Understanding that this is a recognised, real phenomenon — not weakness, not anxiety, not "just getting older" — is often the first thing people need to hear. The second is that there are gentle, evidence-informed holistic practices that many people find supportive during this time.

This article explores some of those possibilities. Nothing here is a prescription. Think of it as a quiet conversation about what might help — and an invitation to explore what resonates with you.

Why Does Cancer Treatment Affect Concentration?

The mechanisms behind cancer-related cognitive changes are still being studied, but researchers have identified several contributing factors:

• Inflammation: Many cancer treatments trigger inflammatory responses in the body, which can affect the brain's normal functioning.
• Hormonal shifts: Treatments that affect oestrogen or testosterone levels — common in breast and prostate cancers — can impact memory and focus.
• Fatigue: When the body is exhausted, the brain is too. Cognitive effort becomes genuinely harder to sustain.
• Emotional load: Anxiety, grief, and uncertainty all occupy mental bandwidth. When your mind is processing something enormous, there's less capacity left for everyday tasks.
• Disrupted sleep: Poor sleep is both a cause and consequence of cognitive changes, creating a difficult cycle during treatment.
• Direct effects of certain treatments: Some chemotherapy agents are known to cross the blood-brain barrier, temporarily affecting cognitive function.

Knowing what's contributing can help you feel less at odds with yourself — and more curious about which areas might benefit most from gentle support.

Holistic Approaches That May Support Mental Clarity

Holistic well-being isn't about doing everything. It's about finding what feels right for your body and your circumstances right now. The practices below span several different modalities — some physical, some reflective, some energetic — and many people find they work best in combination.

1. Mindfulness and Meditation

There is a growing body of research exploring mindfulness-based practices and their potential to support cognitive function in people going through cancer treatment. Mindfulness — the practice of bringing gentle, non-judgmental attention to the present moment — asks very little of you and can be practised in just a few minutes at a time.

For those experiencing cognitive fog, trying to meditate for thirty minutes can feel overwhelming. Starting with a five-minute breath-awareness practice is often far more accessible and, over time, can help train the attention gently back to stillness.

Focused meditation, where attention is directed toward a single point — a candle, the sensation of breathing, a simple sound — can be particularly helpful when the mind feels scattered. Visualisation meditation, where you hold a calm mental image, may also support the brain's capacity for attention without demanding effortful thinking.

Explore meditation practices on Sissoo to find approaches suited to where you are right now — including options that can be done lying down, in short sessions, or guided by voice.

2. Breathwork

Breathing practices sit beautifully between the physical and the mental. When we regulate the breath, we influence the nervous system directly — and a calmer nervous system creates better conditions for clear thinking.

Simple techniques like box breathing (inhale for four counts, hold for four, exhale for four, hold for four) or extended exhale breathing (making the out-breath longer than the in-breath) can help shift the body out of a stress response and into a state more conducive to focus.

Breathwork is gentle enough to be practised in bed, before appointments, or between treatment sessions. It requires nothing but your breath — which, even on the hardest days, is always there.

You can explore yoga and movement therapy on Sissoo, where breathwork is often woven into practice alongside gentle movement.

3. Gentle Movement and Yoga

Physical movement — even in its softest forms — supports blood flow to the brain and can help lift the mental fog that fatigue creates. You don't need vigorous exercise. Gentle walking, restorative yoga, yin yoga, or qi gong can all be deeply supportive during treatment.

Restorative yoga is particularly worth exploring during cancer treatment. It uses props — blankets, bolsters, cushions — to fully support the body in restful poses, allowing the nervous system to settle without effort or strain. Many people find that even thirty minutes of restorative practice leaves their mind quieter and clearer.

Qi gong combines slow, flowing movement with breath and awareness, and has been studied in cancer care settings as a supportive tool for fatigue and well-being. Tai chi, similarly gentle, draws on the same principles.

4. Body Therapies and Touch

When the mind is struggling, the body often holds the key. Touch-based therapies — carried out by a trained and sensitive practitioner who understands the context of cancer treatment — can help regulate the nervous system, reduce anxiety, and create a felt sense of safety that the mind alone may struggle to reach.

Aromatherapy massage, for example, combines the calming effects of therapeutic touch with the cognitive and emotional influence of scent. Certain essential oils — including rosemary, lemon, and peppermint — are explored in aromatherapy for their traditionally stimulating properties, while lavender and frankincense are associated with calm and grounding.

Reflexology — working with reflex points on the feet, hands, or ears — is another gentle option many people find soothing during treatment. Craniosacral therapy offers extremely light-touch work that some find profoundly settling for an overstimulated nervous system.

It's important to work with a practitioner who has experience working alongside people in cancer treatment. Explore body therapies on Sissoo to find practitioners who understand this landscape.

5. Energy Medicine

Energy-based practices approach well-being through the lens of the body's subtle systems — the biofield, energy centres, and vibrational patterns that many traditions hold to be fundamental to health.

Reiki is perhaps the most widely known of these practices and has been increasingly explored in integrative oncology settings. Practitioners work with a light or off-the-body touch to support relaxation and a sense of inner balance. Many people going through cancer treatment report that reiki sessions leave them feeling deeply rested — and rest, as we've seen, is foundational to clearer thinking.

Sound therapy — using instruments like singing bowls, tuning forks, or voice — can also shift the nervous system into states more aligned with focused, quiet attention. Some people find it easier to "arrive" in their own mind after a sound session than through any other means.

6. Nutrition and Nourishment

What we eat affects how we think — and during cancer treatment, nutritional needs can shift significantly. Working with a nutritional therapist or practitioner of traditional herbal medicine who understands oncology contexts can help you explore whether there are dietary adjustments or supportive nutrients that might help reduce inflammation, support energy, and nourish brain function.

This is an area where individual context matters enormously — what's appropriate for one person may not be right for another, depending on treatment type, medications, and other health factors. Always discuss any supplements or significant dietary changes with your medical team first.

7. Speaking and Listening Therapies

Sometimes the cognitive fog of treatment is inseparable from its emotional weight. Grief, fear, identity shifts, and the exhaustion of being a patient — all of these occupy the mind in ways that make clear thinking harder.

Talking with a therapist, counsellor, or integrative coach who understands cancer and its emotional landscape can create space to process what's happening — and, in doing so, free up cognitive and emotional energy that has been quietly consumed by unexpressed feelings.

Approaches like person-centred counselling, integrative therapy, and even hypnotherapy have all been used supportively in cancer care contexts. EFT (Emotional Freedom Technique) — a form of tapping that combines acupressure points with verbal processing — is another approach some people find calming and centering during treatment.

Practical Day-to-Day Supports Worth Knowing About

Alongside holistic practices, some simple everyday adjustments can make a real difference to how you manage concentration during treatment:

• Work with your energy rhythms. If you have a clearer window in the morning, protect it for anything that requires focus. Let the afternoon be gentler.
• Write things down. External memory — notebooks, phone reminders, voice memos — removes the burden from an overloaded brain. It's not a sign of failure; it's intelligent adaptation.
• Reduce cognitive noise. Limit background TV, news, or social media during times when you need to think. Give your brain space to breathe.
• Single-task where possible. Multitasking is a myth even for healthy brains; during treatment, one thing at a time is a kindness to yourself.
• Rest without guilt. Rest is not wasted time. The brain consolidates and restores during rest. It's doing important work.
• Be honest with people around you. Letting others know what you're experiencing can reduce the pressure you put on yourself to perform cognitively in every situation.

A Note on Being Gentle With Yourself

There's something important to name here. When concentration becomes difficult, it's easy to interpret it as a personal failing — to feel frustrated, embarrassed, or frightened by what's happening to your mind. But the brain, like the body, is responding to enormous demands right now. It is not broken. It is not betraying you. It is doing its best under genuinely hard circumstances.

Holistic practices won't necessarily make the fog disappear entirely — and any resource that promises that would be misleading you. What they can do is create better conditions: a calmer nervous system, more restful sleep, reduced anxiety, greater body-awareness, and a sense of being gently held during a difficult passage.

That's not a small thing. That's everything.
