australia recently reported that sleep disorders have become widespread among the adult population. As scary as this thought is, the fact remains that this matter is becoming an epidemic.

Studies released on World Sleep Day indicate that 45% of Australian adults feel satisfied with their sleep, while 38% are dissatisfied. So why is Australia so sleepless? Let me explain the statistics.

Many studies, surveys, and data analyses determined how many face difficulty sleeping and categorise them under demographics.

What keeps the nation awake?

After going through the statistics, I’m sure we are all wondering what keeps most Aussies awake? There are multiple factors to it but let’s see what the data has to say-


  • The Sleep Health Foundation (SHF) said that the prime cause of not sleeping enough is work stress and various lifestyle choices among the younger group.
  • 48.8% complained that their hectic schedule is hampering their sleep. The SHF also mentioned how few people feel attainment with minimal rest and wear it as a badge of pride.


  • The Institute for Social Research (ISSR) has discussed environmental and societal factors playing a role in an individual’s potential to get enough sleep.
  • The Public Health Association discussed how poor accommodation conditions, unemployment, noise, inadequacy in locality safety, financial crisis, etc., have become primary reasons for lack of sleep.
  • According to the SleepFit report, amongst 4000 participants, 37% mentioned the bedrooms being either too hold or cold, 20% interrupted by children, and 17.5% due to external noise.

  • 22% of people work before going to bed, out of which 69% suffer from sleep problems.
  • 40% of Australians drink alcohol during bedtime and could affect both health and sleep behavior.

Results of lack of sleep

I believe everyone is baffled by the numbers. With the above information, let’s see the repercussion of not sleeping enough.


  • Deloitte evaluated that between 2016-17, 3,017 Australians passed away due to sleeplessness. Heart conditions caused 77% of these deaths.
  • Once a month, 29% of people drive in an exhausted state

  • The Disability-Adjusted Life Years (DALYs) figure lost because of poor sleep helped estimate the lost social welfare expenditure of $40.1 billion.

Take measures for improvement.

It is a fact that sleep contributes 88% to our physical and 89% to mental health. Let us see how Australia is taking the initiative.

  • Philips Global Sleep Survey, 2018 reported 63% of Australians are taking measurements for better sleep. 33% watch TV while 31% reduce caffeine consumption.
  • 21% listen to calming music, around 18% set a schedule to wake up, and 18% take prescribed sleep drugs.


Various studies have helped learn about Australian sleep statistics. In one of the studies, 42% of participants have suboptimal sleep. Whereas 20%-23% widespread via sleep period. 16% of participants reported getting their sleep assessed, while 10% accepted one component of sleep care, where 43% was pharmacotherapy. There are still many studies conducting data to update the statistics for improvement and results. Remember, if you love your health, you need to love your sleep.
