You might laugh at the term Netflix Bum, but Australia’s growing obsession with streaming, scrolling and sitting is no joke. Whether it’s back-to-back episodes or endless TikTok loops, the hours we spend glued to our screens are quietly taking a toll on our health – and our backsides.
According to leading physical activity researcher Professor Corneel Vandelanotte, this modern-day lounge room phenomenon (known to weaken the gluteal muscles) is a symptom of a much bigger problem: Aussies are sitting too much, moving too little, and unknowingly putting themselves at risk of a range of chronic diseases.
‘Prolonged sitting is associated with a wide range of health risks, including musculoskeletal problems, heart disease, type 2 diabetes, obesity, and even some cancers,’ Professor Vandelanotte said.
‘It can also negatively impact mental health and increase the risk of premature death. Breaking up prolonged periods of sitting with movement is crucial for mitigating these risks.’
Recent trends show Australian adults are spending more time sitting than ever before, with screen time steadily increasing over the past decade and spiking during the COVID-19 pandemic.
The average adult now spends more than 6 hours each day glued to screens – from streaming services and smartphones to computers and social media.
Serious stuff
While Netflix Bum may sound like a pop culture punchline, the physical symptoms – soreness, stiffness, poor posture and even muscle imbalances – are no joke.
Professor Vandelanotte said the Australian government is taking the issue seriously, with new 24-hour movement guidelines for adults set to be released later this year.
‘The new guidelines will recommend a good balance between time spent sitting, being active and sleeping,’ he explained. ‘Regular moderate to vigorous physical activity can offset many of the health problems caused by prolonged sitting.’
The 10,000 Steps program, led by CQUniversity and supported by the Queensland government, continues to encourage Australians to take simple, proactive steps to break up their sedentary time.
Tips include standing or stretching every 30 minutes, taking walking meetings or lunch breaks, using standing desks, or building movement into screen time by standing or pacing while watching TV.
‘While we all enjoy our screen time, it’s critical to be conscious of the physical toll that extended sitting can take,’ Professor Vandelanotte said.
‘Finding simple ways to move more and sit less can significantly improve your long-term health and wellbeing.’
