How Breath Influences Metabolism

Empowering Breathwork for Metabolic Balance & Nervous System Resilience when dealing with Hashimoto’s

Hashimoto’s thyroiditis is a chronic autoimmune disease where the body’s immune system mistakenly attacks the thyroid gland. Over time, this leads to hypothyroidism — a state of underactive thyroid function. Symptoms include persistent fatigue, brain fog, difficulty losing weight, sensitivity to cold, dry skin, thinning hair, and mood fluctuations. While thyroid hormone medication can correct hormone levels in the blood, many people still struggle with unresolved symptoms that affect their quality of life and day-to-day vitality. This can have various reasons, such as individual responses to the medication, other coexisting conditions, or the incomplete restoration of normal metabolic function.

While there’s no cure for Hashimoto’s, which is typically treated with thyroid hormone medication (commonly levothyroxine), its effects can be softened and better managed through consistent, personalized care. One of the most underestimated yet powerfully restorative tools in that journey is your breath.

🌬️ Silent Strength: How Breath Can Support a Slowed Metabolism

You might be doing everything right — following your treatment, eating well, and showing up for yourself — yet still feel drained, stuck, or disconnected from your energy. That’s where breath can offer gentle support.

In my work at Arogya, I repeatedly observe people with shallow, tense breathing patterns who struggle to access diaphragmatic breath. These patterns, often unconscious, reflect a nervous system stuck in stress and can subtly undermine vitality and metabolic balance over time.

Your breath, thyroid function, and metabolism are deeply interconnected. Under chronic stress, your nervous system may shift into a prolonged alert state, causing changes in your breathing pattern. Instead of full, relaxed exhalations, some people begin to over-breathe — inhaling too much and not exhaling fully. This reduces carbon dioxide (CO₂) levels in the blood, which paradoxically hampers oxygen delivery to your cells due to the Bohr effect. When CO₂ levels drop too low, hemoglobin holds onto oxygen more tightly, preventing it from releasing efficiently into your tissues — leaving you feeling fatigued and foggy despite breathing more. This subtle dysregulation can quietly undermine your energy and metabolism over time.

Breathing slowly, softly, and with awareness helps reverse that process. It stimulates the parasympathetic nervous system, sends signals of safety to the brain, and allows the body to return to a state where healing processes can be supported. It’s a small act — but one with profound ripple effects.

Just one breathing session may feel good in the moment, but lasting impact comes with consistency. Like any other practice, breathwork needs regularity to re-pattern the nervous system and support metabolic balance over time.


Slow, diaphragmatic breathing improves oxygen and carbon dioxide balance in the blood, supporting cellular respiration — the process by which your cells create energy. Better breathing equals better energy.

This calm, regulated breathing also activates the vagus nerve, enhancing heart rate variability (HRV) — a marker of nervous system resilience. Have you heard of HRV before? Or tracked it with a wearable? It can be a valuable insight into how your body responds to stress — and how well you’re recovering.

Higher HRV is linked to better metabolic flexibility, emotional regulation, and adaptability.

Robin L. Rothenberg’s book Restoring Prana highlights how dysfunctional breath patterns like over-breathing or breath-holding lower CO₂ levels, impair oxygen use, and disrupt physiological balance — particularly challenging for those already dealing with autoimmune-related fatigue like from Hashimoto’s.

Breathwork supports:

  • More stable metabolism
  • Better nutrient-to-energy conversion
  • Calmer mood and sharper focus
  • Hormone balance through vagal stimulation

These practices are gentle, accessible, and safe even when you’re feeling deeply fatigued:

Soft Belly Breathing (3–5 min). You can practise seated with a straight spine or comfortably lying down in constructive rest pose (see previous picture).

  • Inhale gently through the nose
  • Exhale slowly through pursed lips
  • Let the belly rise and fall

Nadi Shodhana (Alternate Nostril)

  • Balances brain hemispheres and calms the nervous system

Consistency matters. Practicing 5–10 minutes a day can create meaningful shifts over time.

📱 Tools for Practice: Guided Frequency Breathing

Resonance frequency breathing helps establish a coherent, slow breathing rhythm — usually between 4.5–6 breaths per minute. This pace enhances HRV, vagal tone, and oxygen–CO₂ balance.

Both longer exhales and balanced inhale-exhale cycles are beneficial. Longer exhales calm the system; balanced rhythms promote equilibrium. Try a few patterns for 15–20 minutes and stick with what leaves you feeling grounded.

  • The Breathing App – visual/audio cues for frequency breathing
  • Yudemon HRV App – guides breathing and tracks HRV

⌚ Biofeedback: Monitor Your Progress

Devices like Oura, Apple Watch, and Fitbit let you track HRV and breath trends. While these devices are not always 100% accurate, they can provide useful insights and trends over time — offering a helpful sense of direction rather than precise diagnostics.

Benefits:

  • Visualize progress
  • Stay consistent and boost motivation through measurable change
  • Adapt practices based on physiological response

⚠️ Contraindications, Safety & Professional Guidance

  • Avoid breath holds or strong pranayama in the early stages of fatigue or chronic illness
  • Focus on gentle, nasal, diaphragmatic breathing
  • Stop or adjust if dizziness or discomfort occurs

It’s important to note that not every type of breathwork is suitable for individuals with Hashimoto’s or chronic fatigue. The practices recommended here are soft, gentle, and diaphragmatic in nature. Many modern breathwork styles use intense, forceful breathing techniques that may overstimulate the system — these are not appropriate in this context.

If you’re unsure where to begin or struggle with breathing patterns, it’s best to seek support from a qualified breath therapist or yoga therapist. Not all breathwork facilitators are trained to work with chronic health conditions, so ensure they have relevant expertise before starting a guided program.

Always consult your healthcare provider if you have specific concerns.
