The space between diagnosis and performance is mostly lived in the details of daily life. What you eat, how you hydrate, the air you breathe, how you sleep, and how you clear your airways — these are the levers that make everything else possible.
Do these today
Five things with meaningful impact that cost nothing and take under 10 minutes each.
Clears overnight mucus accumulation before anything else stresses your airways.
Hydration thins mucus and makes morning clearance significantly easier.
Indoor air is often more polluted than outdoor. Fresh air exchange matters daily.
On high pollution or high pollen days, adjust outdoor training intensity accordingly.
Reduces overnight mucus pooling and can meaningfully reduce morning cough load.
Pillar 01
Food doesn't cure bronchiectasis. But chronic inflammation is the engine of disease progression — and diet is one of the few levers you can pull daily. Anti-inflammatory eating isn't a trend here; it's a management tool.
Chronic inflammation drives BX progression. An omega-3 rich diet — oily fish, walnuts, flaxseed — alongside plenty of colourful vegetables, provides the building blocks for a less reactive inflammatory environment. This isn't a cure, but it's a meaningful modifier.
Breathing is muscular work. The diaphragm and intercostal muscles need adequate protein to maintain function — especially under training load. Aim for 1.6–2g per kg of bodyweight if you're training seriously. Spreading intake across meals improves absorption.
A full stomach pushes up against the diaphragm and reduces lung volume. Leave 2–3 hours between a full meal and high-intensity training. A small carbohydrate snack 60–90 minutes prior is fine.
Vitamin D deficiency is common and is associated with increased respiratory infection susceptibility. Many people with BX, especially in Northern Europe, are deficient. Ask your GP to test levels and supplement if indicated.
Both increase systemic inflammation and can impair immune response. During an exacerbation, treat nutrition as part of your recovery protocol — not an afterthought.
I have found that what I eat makes a massive difference. The days when I eat unhealthy, generally my lungs are struggling much more. I also find that certain types of food / drink exacerbate the creation of mucus. In particular, milk is one that has an impact. Another thing I pay attention to is not to eat too late. Anytime I eat after 8pm, the effects are noticable. This is likely related to heartburn as well, but for impacts mucus accumualtion.
Pillar 02
Hydration is arguably the most underrated airway management tool available to people with BX. It is free, immediate in effect, and consistently overlooked. Mucus viscosity is directly affected by systemic fluid status.
Mucus viscosity drops significantly with adequate hydration. Well-hydrated mucus is easier to mobilise with ACT, easier to cough up, and less hospitable to bacterial colonisation. Before reaching for a nebuliser, make sure you're drinking enough.
More if you're training hard, in a warm environment, or in an exacerbation. Sputum colour and volume are useful hydration feedback — thick, darker sputum is often a sign of dehydration before it's a sign of infection.
Moderate coffee and tea intake is fine and won't cause meaningful dehydration in habitual consumers. However, heavy caffeine intake can increase mucus viscosity and disrupt sleep, both relevant for BX. Aim to match each caffeinated drink with an equivalent volume of water.
Inhaled hypertonic saline (3% or 7%) works by drawing water into the airway surface liquid, hydrating mucus from the inside. It's the pharmaceutical version of what good systemic hydration supports naturally. Discuss with your respiratory team if you're not already using it.

I have found that proper hydration is a big challenge to me that should take higher priority. I often find that I am not hydrating enough, but struggle to be consistent. Knowing that this can make a massive difference though should be a real driver. Also, I for sure take too much coffee, another area that needs focus and more management.
Pillar 03
Your airways are in direct contact with the air around you — more so than most people because you're breathing harder and more often as an athlete. What's in that air matters significantly, and the good news is that most of the highest-impact factors are controllable.
Check AQI daily. Move intense training indoors on red/very unhealthy days.
Track pollen calendar. Many BX patients have co-existing airway sensitivity.
Mould spores are a significant trigger. Fix any damp, use dehumidifier if needed.
Bleach, spray cleaners, and aerosols can trigger bronchospasm. Use unscented, non-aerosol alternatives.
Cold air triggers airway narrowing. Warm up properly; consider a buff/scarf over mouth in winter training.
Air exchange matters more than most people realise. Open windows daily, especially in morning.
For a long time, I have not considered Air Quality as something to control. That being said, there are a number of things you can influence. Being aware of this and understanding if differences in air quality impact your comfort and/or exacerbations is important to monitor over time.
Pillar 04
Sleep is where your body repairs, consolidates training adaptations, and mounts immune responses. Disrupted sleep (which many people with BX experience due to nocturnal cough) undermines all of it. Treating sleep as a performance variable, not a luxury, changes outcomes.
A 10–15cm elevation (via a wedge pillow or adjustable bed head) reduces overnight mucus pooling in the lower airways. Many people with BX report significantly reduced morning cough load from this single change.
A short airway clearance session 30–60 minutes before sleep reduces the mucus load your airways are managing overnight. Not a full session, 10–15 minutes of ACBT or PEP is sufficient. Avoid vigorous clearance immediately before sleep as it can be stimulating.
If nocturnal cough is frequent, it's worth discussing with your respiratory team, causes include reflux, postnasal drip, and inadequate daily clearance. Each has a different solution. Don't accept poor sleep as inevitable with BX.
Sleep deprivation impairs immune function and increases susceptibility to respiratory infection. Prioritising sleep during high-training-load periods is not optional, it's part of the protocol.
8 hours of frequently interrupted sleep is not the same as 7 hours of consolidated sleep. If you're tracking training, track sleep quality too. Resting heart rate and HRV (via a wearable) are useful proxies.
For me, sleep is one of the key influences in managing my BX. As soon as I sleep less than 7 hours, I can feel the impact immediatly. This pretty much always leads to more coughing, more mucus, and a harder time to clear mucus. Getting closer to 8 hours of uninterupted sleep makes things even better. I struggle to get the proper amount of sleep but am very aware that this is one of the major factors in managing my BX.
Pillar 05
BX management isn't a collection of isolated actions it's a rhythm. The same interventions work far better when they're consistent and sequenced correctly. This is the framework I've built around training. Adapt it to your own schedule; the principles are what matter.
Pillar 06
Airway clearance therapy is the single most important daily intervention for most people with bronchiectasis. The techniques below range from the foundational to the advanced. Every person with BX should have at least one technique assessed and taught by a respiratory physiotherapist.
The foundation of most BX airway clearance. Three phases: breathing control (relaxed diaphragmatic breathing), thoracic expansion exercises (deep breaths with holds), and forced expiration technique (huffing). Typically 4–6 cycles per session.
Ask your respiratory physio to assess your technique in person — small adjustments make a large difference.
Devices that create oscillating positive expiratory pressure, loosening mucus from airway walls while you breathe out against resistance. Many people find these more effective than ACBT alone, especially for lower lobe disease.
Prescription and technique guidance from your physio. Not all devices suit all patients.
A self-drainage technique using controlled breathing at different lung volumes to move mucus from peripheral to central airways without coughing. Has a steeper learning curve but excellent evidence. Often preferred for people who need hands-free clearance.
Takes several sessions with a physio to learn correctly. Worth the investment.
Breathing in through the nose, out slowly through pursed lips. Slows breathing rate, reduces dynamic airway collapse, and can reduce breathlessness during activity. A useful tool mid-exercise or during breathless episodes.
Can be self-taught; practice when calm before using during exertion.
Conscious use of the diaphragm rather than accessory muscles to drive breathing. Reduces the energy cost of breathing, supports ACT effectiveness, and forms the base of most breathing rehabilitation programmes.
Practice supine initially — one hand on chest, one on abdomen. The abdomen should rise, not the chest.
