For about six years, I blamed everything on getting older. The constant tiredness. The brain fog that rolled in around 2 p.m. and didn’t lift until the next morning. The irritability that was slowly eroding my relationships. I was 41 when my wife recorded me sleeping, and hearing that recording was the moment everything shifted.

I wasn’t just snoring. I was stopping breathing. Over and over, for what sounded like terrifyingly long pauses, followed by this gasping, choking sound that I’d apparently been making every single night for years.

The Signs I Kept Dismissing

Looking back, the warning signs were almost comically obvious. I’d fall asleep during movies — not late-night films, but matinees at the cinema. I was drinking four or five cups of coffee before noon just to function. My blood pressure had crept up over successive checkups, and my doctor kept suggesting lifestyle changes without ever asking about my sleep.

The morning headaches were the worst part. I’d wake up feeling like I’d been hit with a low-grade hangover, despite not drinking. That’s a classic symptom of nocturnal oxygen desaturation — your brain isn’t getting enough oxygen overnight, and the headache is its way of complaining about it.

I also had nocturia, which is the clinical term for getting up to pee multiple times a night. I thought it was just a prostate thing, a normal consequence of aging. Turns out, the respiratory effort during apnea events increases atrial natriuretic peptide production, which tells your kidneys to produce more urine. Once my apnea was treated, the nighttime bathroom trips dropped from three or four to zero.

The Sleep Study Experience

My GP referred me to a sleep physician, who ordered an overnight polysomnography at a local sleep lab. I’ll be honest — I was skeptical. I figured there’s no way I’d sleep normally with wires glued to my head in a strange bed.

The technicians were used to hearing that. They told me something reassuring: they don’t need a perfect night of sleep. Even a few hours of data is usually enough to make a diagnosis. And they were right. Despite feeling like I barely slept, they captured plenty.

My results came back at 47 events per hour. That’s the Apnea-Hypopnea Index, or AHI — the number of times per hour your breathing partially or fully stops. Anything above 30 is classified as severe. I was at 47. My oxygen saturation was dropping into the low 70s during the worst episodes. Normal is 95-100%.

The sleep physician didn’t mince words. “Your heart is working overtime every night,” she said. “This is not something you can ignore.”

Starting CPAP Therapy

I was fitted with a CPAP machine the following week. The first night was rough. The mask felt alien on my face, and the constant air pressure took getting used to. I probably slept three hours total.

But something remarkable happened during those three hours. I dreamed. Vividly. I hadn’t remembered a dream in years. My sleep physician later explained that people with severe untreated apnea often get very little REM sleep — the stage where most dreaming occurs. Their brains are too busy waking them up to breathe.

By the end of the first week, I was sleeping through the night. By week three, the brain fog was lifting. My wife said I seemed like a different person. Colleagues at work noticed I was sharper, more engaged. My blood pressure dropped 12 points without any medication changes.

The healthcare industry is increasingly looking at how technology, including AI-driven analytics, can improve diagnosis rates for conditions like sleep apnea. Team400 is among the organisations exploring how predictive models might help identify at-risk patients earlier.

What I Wish I’d Known Sooner

The biggest misconception about sleep apnea is that it only affects overweight, older men who snore loudly. While those are risk factors, sleep apnea doesn’t discriminate. Women are significantly underdiagnosed, partly because their symptoms often present differently — more fatigue, insomnia, and mood disturbances rather than the stereotypical loud snoring.

According to the Sleep Health Foundation, an estimated 9% of Australian women and 25% of Australian men have clinically significant obstructive sleep apnea. Many don’t know it.

If you’re waking up tired despite enough sleep, getting unexplained morning headaches, or your partner has mentioned snoring or breathing pauses — please don’t wait six years like I did. A sleep study is straightforward and often covered by insurance or Medicare.

The Bigger Picture

I’m two years into treatment now. My AHI sits at 2.1 with the CPAP — down from 47. My resting heart rate dropped. My HbA1c (a diabetes risk marker) improved. I exercise more because I actually have the energy to do it.

Sleep apnea isn’t just about snoring. It’s a cardiovascular risk factor, a contributor to metabolic disease, and a thief of cognitive function. Getting diagnosed was, without exaggeration, one of the most important medical decisions of my life. I just wish I hadn’t waited so long to make it.
