With each passing year there is new research showing the sleep disorders are more prevalent and harmful than previously thought. However, we as individuals often overlook the signs and symptoms of an underlying condition that is both serious and treatable. Being aware of the common sleep conditions can help you know when to seek out medical advice and treatment to improve your sleep health.
Sufferers of obstructive sleep apnea experience a partial or complete interruption of breathing during sleep. This is caused by repeated collapse of the upper airway while sleeping. People with this condition are often tired during the day. They may also snore, wake up gasping or choking, or awake with a headache. 17% of the general population is thought to have OSA, but the prevalence is higher in men, in older people, and in those who are overweight or obese. A combination of these factors could see your chance of developing OSA reach as high as 49%.
Those with untreated OSA risk developing cardiovascular disease like heart attack, metabolic disease like diabetes, stroke, and depression. There are also the complications of being overly tired, such as decreased ability to learn and concentrate, poor performance at work, and increased chance of a motor vehicle accident.
OSA is typically diagnosed with a sleep study, which you can do at home or in a sleep lab. The best first step is to speak to your GP who can help organize the sleep study or send you to a specialist sleep physician.
If your study shows that you do have OSA, there are a number of treatment options. More mild forms of the condition can be managed by lifestyle modifications like weight loss and smoking cessation, or by a dental device called a Mandibular Advancement Splint, which pushes the jaw forward to help open the airway at night. The most effective treatment is a Continuous Positive Airway Pressure, or CPAP machine. This works by gently blowing pressurized air into your upper airway to prevent collapse.

Like obstructive sleep apnea, CSA causes a disruption of breathing during sleep. However, in this condition the route cause is the interruption of the brain signals that control the muscles of breathing. In additional to the fatigue that can accompany any form of sleep apnea, CSA sufferers can also wake up feeling breathless, feel short of breath while lying down (orthopnea), or have chest pain. Other medical conditions like heart failure, cardiac arrhythmia and stroke can all contribute to the development of CSA. Central sleep apnea can then cause further cardiovascular problems.
Central sleep apnea can be diagnosed with an in lab sleep study. Specialist physician involvement is important, and CSA patients should see both a cardiologist and a sleep physician to make sure their heart and sleep problems are well managed. Treatment often involves the use of a positive pressure machine like CPAP, a ventilator like bi-level positive airway pressure (BPAP), or a more complex device like Adaptive Seroventilation (ASV).
Narcolepsy is a condition characterized by the uncontrollable urge to sleep during the day. While the exact cause is unknown, it is thought that the underproduction of certain brain chemicals (like hypocretin) are responsible for the disorder. Apart from attacks of sleepiness, sufferers can also experience a loss of voluntary muscle tone (cataplexy) and hallucinations that would only occur in health people as they were transitioning from wakefulness to sleep (hypnagogic hallucinations).
You are at higher risk of developing narcolepsy if you have a family history of the condition of if you have had brain injuries in the past. The chances of developing the disorder also increase with age. Sufferers often deal with personal and professional issues, including poor work performance, relationship problems, or stigma due to poor understanding of the disease. You are also at higher risk of injury when you have an episode.
Narcolepsy is diagnosed by a special type of sleep study called a Multiple Sleep Latency Test, or MSLT. This is carried out during the day and looks at how quickly you fall asleep. All patients with narcolepsy should be managed by a specialist sleep physician.
People with restless leg syndrome feel a discomfort in their lower limbs that is only relieved by moving their legs. They will move their legs around more during the transition from wakefulness to sleep and throughout the night. This causes a disruption of sleep, which leads to excessive daytime fatigue.
You are more likely to develop restless leg syndrome if you have a family history of the condition, or if you have another medical problem that effects the nervous system (e.g. peripheral neuropathy that can accompany diabetes).
You will most likely receive your diagnoses based on your description of your symptoms and a physical examination, although you may be asked to do an in-lab sleep study.
There are some medications that can be used to alleviate the symptoms. This condition is best managed by a specialist sleep physician.
Sleep better. Eat smarter. Drive safer. Your next drive is only as safe as your last night’s sleep and your last meal. Prioritising good rest and balanced nutrition is one of the simplest ways to protect yourself and others on the road.
Night shifts + long drives = high fatigue risk. Microsleep kills. Sleep debt, low alertness and early-morning circadian dips all combine to impair your reaction time. Prioritise rest, take breaks, nap when needed, and never ignore the warning signs. Your safety depends on it.
Struggling to stay awake behind the wheel? Untreated obstructive sleep apnoea can make you dangerously drowsy behind the wheel, raising your risk of a crash up to seven times higher. If you often feel tired, unfocused, or nod off easily, don’t ignore the signs. Chat to your doctor today and drive safely for yourself and everyone around you.
Every time you start your car, you’re making a decision. You’re deciding whether you’re alert enough to operate a machine that weighs nearly two tonnes and travels at high speeds. In Australia, thousands of drivers make this decision every single day without realising they’re putting themselves and others at serious risk. The culprit behind this risk? Fatigue, one of the most underestimated threats on our roads.
After a big week — work pressures, long days, life admin, and everything in between — sleep becomes more than rest. It becomes repair. Even though we spend about one-third of our lives asleep, sleep itself is still surprisingly complex and deeply essential. While your mind drifts off, your body begins some of its most important work: rebuilding, rebalancing, and restoring your strength.
A steady heartbeat is something most of us take for granted — until it isn’t. Atrial fibrillation (AF) is the most common type of sustained irregular heartbeat, or arrhythmia, in adults. It occurs when the heart’s upper chambers (the atria) beat rapidly and out of sync with the lower chambers. This irregular rhythm can cause the heart to pump blood less efficiently, increasing the risk of stroke, heart failure, and other complications.
When it comes to looking after your heart, most people think of diet and exercise straight away. But there’s another pillar that quietly plays just as big of a role: sleep. The truth is, your eating habits and your sleep habits feed into each other every single day, creating a cycle that can either support your heart — or strain it. Understanding this relationship is the first step to making small changes that add up to a healthier life.
This World Diabetes Day is a good moment to pause and look at a relationship many people don’t realise is so deeply intertwined: sleep, diet, and diabetes risk. Poor sleep isn’t just about feeling tired or groggy the next day — it has real, measurable effects on our metabolic health, appetite, and long-term risk of developing type 2 diabetes.
There’s something about spring that makes everything feel lighter. The air gets warmer, the days stretch a little longer, and suddenly we feel inspired to refresh our homes, wardrobes, and routines. But one area we often forget — even though it affects almost every part of our wellbeing — is sleep.
