“If sleep does not serve as a vital function, then it is the biggest mistake the evolutionary process ever made”

Dr Allan Rechtschaffen (Sleep researcher)

Do you or your partner snore?

Do you find yourself getting really sleepy during the day?

Do you wake up tired no matter how long you have slept?

Do you wake up with a dry mouth?

If you answer yes to any of the above questions, YOU ARE NOT ALONE.

Sleep Is A Top Priority For Health

Researchers have found that relatively moderate levels of fatigue impair performance to an extent equivalent to or greater than is currently acceptable for alcohol intoxication.

What is worse is that sleep-deprived individuals do not even realise they are fatigued and that their performance is impaired.


Sleep is a keystone habit, and making sure you are getting good and regular sleep should be a top priority.

When you are feeling well rested every day, it becomes easier to tackle life’s other obstacles.

Why do we need sleep?

  • During sleep we allow the body to actively recover itself.
  • Our bodies process the waste that accumulates in our cells during the day.
  • Sleep promotes the growth of new nerve cells and brain function.
  • When we sleep well, we crave less sugary food and feel more energetic.

About City Sleep Clinic

Joel Simpson
runs the City Sleep Clinic.

He has lectured across the world in Inspiratory Muscle Training and across APAC in Sleep Disordered Breathing.

He works with children and adults who have sleep and breathing issues, from asthma to sleep apnea to insomnia.

Joel excels at building plans to improve patients’ sleepiness and snoring using his deep understanding of Sleep Disordered Breathing.

He works alongside top medical specialists and health care providers from GP's, dentists, ear, nose & throat specialists, maxillofacial surgeons, neurologists to psychologists, to ensure his patients receive the best possible holistic care and outcomes.

Joel has also worked with world class athletes across a number of sports on both breathing performance as well as helping to mitigate the effect travel may have on circadian rhythms, sleep and ultimately sports performance.

Our Vision

At City Sleep Clinic we want everyone to share our vision that sleep is a vital component of health and well-being and that
everyone living with sleep issues should have access to effective, consistent, evidence-based support.

At the City Sleep Clinic we believe that sleep is one of 3 core needs for good overall health, alongside exercise and diet.

Our mission is to help people get treatment and take preventative measures to look after their sleep health as well as stopping sleep issues developing into bigger health problems.

What to Expect

Step 1

Is an initial 45 minute consultation with our Sleep Therapist. This includes:-

- A full screening, including insomnia screening, sleep disordered specific screening, general sleep disorder screening (measuring tiredness & fatigue), and also a general health screening to ensure no other external issues are impacting sleep.

- You will be asked to complete a sleep diary as part of the process.
We will help you to understand what can cause and contribute to sleep problems, look at what normal sleep is, and introduce the techniques involved in the sleep therapy.

Step 2

The next step would likely be a recommendation to do a one night Level 2 Sleep Study.
This is done using an at-home polysomnography and will provide us with the full diagnostics to help us determine what the exact sleep issue is and what is causing it.

Step 3

From this we will then put together a holistic treatment plan, bringing in other health professionals if required, and begin working towards your goal of improved sleep.

For some issues we will treat in-house; for others we will refer out. Throughout, we will operate as a central pivot in the process, ensuring that you are getting the right treatment and desired outcomes.

What is sleep?

 Sleep is a complex process of restoration and renewal for the body. Scientists still do not have a definitive explanation for why humans have a need for sleep.

It is influenced by circadian rhythms, which are controlled by brain neurons that respond to light, temperature, hormones and other signals and comprise the body’s biological clock.


How many hours of sleep do I need per night?

Individuals vary greatly in their need for sleep; there are no established criteria to determine exactly how much sleep a person needs. Eight hours or more may be necessary for some people, while others may consider this to be too much sleep.

For the adult population in general, seven to eight hours of sleep is recommended.

The National Institutes of Health (NIH) (US) say that "sleep needs vary from person to person, and they change throughout the lifecycle.

Newborns sleep between 16 and 18 hours a day, and children in preschool sleep between 10 and 12 hours a day. School-aged children and teens need at least 9 hours of sleep a day.

Research suggests that adults, including seniors, need at least 7 to 8 hours of sleep each day to be well rested and to perform at their best."

What is sleep apnea and what causes it?

Sleep apnea is when a person has multiple pauses in their breathing pattern during sleep.

The three types of 
sleep apnea are central apnea, obstructive apnea, and a mixture of central and obstructive apnea.

Obstructive sleep apnea (OSA) is by far the most common, and is caused by the collapse of the 
airway during sleep.
Snoring is one of the main symptoms.

Central sleep apnea is caused by a failure of the brain to activate the muscles of breathing during sleep.

Obstructive sleep apnea is diagnosed and evaluated by looking at a individual’s medical history, doing a physical examination and polysomnography (a sleep study).

What are the complications of sleep apnea?

The complications of sleep apnea include high blood pressure, strokes, heart disease, anxiety, depression, and daytime sleepiness which can lead to an increased risk of automobile accidents, as well as difficulty concentrating, thinking and remembering.

What are the treatment options for sleep apnea?

There are both nonsurgical and surgical treatment options for obstructive sleep apnea. Non-surgical options include behavior therapy, such as weight loss, medications, dental appliances, continuous positive airway pressure, bi-level positive airway pressure, and auto-titrating continuous positive airway pressure.

If I snore do I have sleep apnea?

Snoring and sleep apnea are often confused or thought of as interchangeable. This is not correct. While all untreated obstructive sleep apnea sufferers snore, only some people who snore have sleep apnea.⁠

Snoring is simply a sound caused by vibration during breathing. The vibration is the result of a partially blocked airway in the mouth, nose, or throat.⁠

Does asthma cause sleep apnea?

While many people suffer from sleep apnea who aren't asthmatic, studies suggest that people with asthma are at increased risk for sleep apnea and that sleep apnea actually can worsen asthma and asthma symptoms in a number of ways.

A Chance for Better Breathing

At City Sleep Clinic we help patients with a multitude of breathing issues, the most common being asthma, but also cystic fibrosis and some neurological diseases.

For all of these, there are a number of evidence-based additive treatments that can be used alongside traditional therapies. The main one we use is a technique called Inspiratory Muscle Training (IMT).

IMT was first researched in the 1980’s, and by the 2000’s the evidence of the positive effects of breathing training were being seen across a number of areas, from asthmatics, to helping post-operative cardiac patients, to patients with cystic fibrosis, all the way up to improving athletic performance.

IMT works by creating a resistance when you breathe in. This strengthens your breathing muscles by making them work harder. It is like dumbbells for your diaphragm. It restores inspiratory muscle strength, which in turn reduces breathlessness and increases exercise tolerance. Well-trained inspiratory muscles need less blood(?) than weaker inspiratory muscles, meaning there is more for the other muscles you are using.

In the case of asthma, Inspiratory Muscle Training (IMT) is used to improve shortness of breath. Although this is certainly not a replacement for vital medications, it provides an added benefit through improving exercise tolerance, breathing pattern dysfunction and shortness of breath.

In the case of athletes, we can use IMT to help improve their overall sports performance, e.g. a study on cyclists saw an improvement in time trial times of 4.7% - equivalent to slashing 3 minutes off of a 40k time trial. Numerous studies have shown similar results across a whole range of sports, from sprinting to rowing.

The tool we use is called airofit (
https://www.airofit.com/), and just like physio, set patients a training program (usually 4-8 weeks), whereby we progressively overload, using a breathing training program / protocol.
