Two people can get eight hours of sleep and wake up feeling completely different. So why is that?💤

While sleep duration is important, it doesn’t necessarily tell us how restorative your sleep has been.

If you’re consistently waking up exhausted despite getting the recommended amount of sleep, there may be more going on beneath the surface.

Underlying sleep conditions such as obstructive sleep apnoea, periodic limb movement disorder or other sleep-related disturbances can interrupt your sleep quality, sometimes without you even realising it.

These disruptions can prevent you from getting the restorative sleep your body needs, leaving you feeling tired, struggling to concentrate or relying on caffeine to get through the day.

If you’re doing all the right things but still waking up tired, it may be time to investigate why.

A diagnostic sleep study can help identify certain underlying sleep disorders and provide valuable information to guide appropriate treatment.

Heading somewhere a little higher up? 🏔️

If you have asthma or another respiratory condition, it’s worth thinking about your breathing before you travel.

At higher altitudes, atmospheric pressure is lower. While the percentage of oxygen in the air remains roughly the same, the lower pressure means less oxygen is available with each breath. Your body responds by breathing faster and working harder to get the oxygen it needs.

For most people with well-controlled asthma, travelling to higher altitudes is generally possible. However, the combination of altitude, cold and dry air, and increased activity such as hiking or skiing may trigger symptoms in some people.

Before you travel:
🏔️ Make sure your asthma is well controlled
💨 Keep your reliever medication easily accessible
📋 Have an up-to-date Asthma Action Plan
💊 Pack enough medication for your entire trip, plus some extra
🥾 Give your body time to adjust before jumping into strenuous activity
🩺 Speak with your doctor before significant high-altitude travel if you have an existing respiratory condition or your symptoms aren’t well controlled

If you’re experiencing ongoing respiratory symptoms, respiratory testing can help provide your healthcare team with objective information about how your lungs are functioning.

Speak with your GP about whether respiratory testing may be appropriate for you.

An ongoing cough, wheezing, shortness of breath or tightness in your chest can have a number of possible causes. 🫁

One thing your doctor may want to investigate is inflammation within your airways.

That’s where a FeNO test can help. 💨

FeNO testing measures the amount of nitric oxide in your exhaled breath. Higher levels can be associated with the type of airway inflammation commonly seen in asthma, providing your healthcare team with useful information when investigating symptoms.

FeNO testing may also be used in people already diagnosed with asthma to monitor airway inflammation and help assess how well certain treatments are working.

The test is quick, painless and non-invasive. You simply take a deep breath in and breathe out slowly and steadily into a small device.

At CRS, FeNO testing is available for adults and children aged 5 years and over.

Speak with your GP or healthcare provider about whether FeNO testing may be appropriate for you.

Sleep apnoea treatment isn’t one-size-fits-all. 🌙

Even when CPAP is the recommended therapy, there are different machines, masks and setups available, and finding an option that feels comfortable and works for you can make a big difference.

At CRS, we offer a range of sleep therapy options, including CPAP machines and masks, positional therapy and custom Mandibular Advancement Splints (MAS).

Our team can help you understand your options, find the right setup for your individual needs and provide ongoing support with your therapy.

We even offer CPAP and positional therapy trials so you can try out different setups before you commit to purchasing a machine of your own.

When we assess lung function, we’re looking at much more than how deeply you can breathe. 🫁

During respiratory testing, you may be asked to perform a number of different breathing manoeuvres. Each one is designed to gather particular information about your lung function, from how much air your lungs can hold and how quickly you can move air, to how effectively your lungs perform different aspects of breathing.

And you don’t need to know what to do beforehand.

Your respiratory scientist will explain and demonstrate each manoeuvre, guide you through it as you go and give you time to repeat measurements where needed. The equipment records your responses, helping to build an objective picture of your respiratory function.

So if it’s your first time having respiratory testing, there’s no need to practise. We’ll guide you through every breath.

Short of breath: is it your heart or your lungs?

It’s not always easy to tell.

Breathlessness can be associated with conditions affecting the lungs, such as asthma, COPD or other respiratory conditions. But it can also occur when the heart isn’t pumping as effectively as it should, or with certain heart rhythm or valve problems.

And sometimes, the cause isn’t limited to the heart or lungs at all.

That’s why the symptom itself is only part of the picture. Depending on your symptoms and medical history, your doctor may recommend investigations such as lung function testing, an ECG, echocardiogram or other cardiac and respiratory testing to help understand what may be contributing.

Lung function testing can assess how well your lungs are working, including how effectively they move oxygen into the bloodstream. A Cardiopulmonary Exercise Test (CPET) may also be useful in differentiating between cardiac, respiratory and other potential causes of breathlessness by assessing how the heart, lungs and muscles respond during exercise.

At CRS, our team provides diagnostic testing to help referring practitioners investigate symptoms such as unexplained breathlessness. We also offer cardiac testing through our other business, Cardio Vascular Services (CVS).

If you’re experiencing new, severe or rapidly worsening shortness of breath, particularly with chest pain, fainting or other concerning symptoms, seek urgent medical attention.

Does your sleep apnoea change depending on how you sleep? 💤

For some people, the answer is yes. Obstructive sleep apnoea can be significantly worse when sleeping on the back compared with sleeping on the side, a pattern often referred to as positional obstructive sleep apnoea.

When lying on your back, gravity can affect the soft tissues surrounding the upper airway and increase its tendency to narrow or collapse during sleep. A sleep study can record both your breathing events and your body position, helping your sleep specialist determine whether there is a relationship.

If your OSA is strongly position-dependent, Positional Therapy may be considered as part of your treatment.

This is designed to encourage side sleeping and reduce the amount of time spent sleeping on your back. It isn’t appropriate as a standalone treatment for everyone, so treatment should be based on your individual sleep study findings and clinical assessment.

“I only smoke on weekends.” It’s something respiratory clinicians hear often.🚬

Because occasional smoking doesn’t usually leave you feeling breathless or unwell, it’s easy to assume it isn’t having much of an impact. But inside your lungs, a different story is unfolding.🫁

Every cigarette contains thousands of chemicals that irritate the airways and trigger inflammation. 💨

One of the first structures affected are the cilia, microscopic hair-like projections that constantly move mucus, dust and germs out of your lungs. When these become damaged, your lungs become less efficient at clearing harmful particles.
The challenge is that your lungs have a remarkable reserve capacity. They can continue functioning well even while damage is occurring, which means many people don’t notice symptoms until years later.

🚭While smoking fewer ci******es is less harmful than smoking heavily, there is no known safe level of cigarette smoking. Each exposure contributes to inflammation and repeated injury to lung tissue, even if it’s “just on the weekend.”

That’s why protecting your lung health isn’t about waiting until you feel symptoms, it’s about understanding what happens long before they appear.

If you’re concerned about your lung health, the first step is visiting your trusted GP, and requesting a referral to us for a respiratory test.
