Social apnea: The new sleep disorder trend that has experts concerned
Australian researchers have identified a new sleep disorder trend, dubbed 'social apnea', potentially sparked by weekend lifestyle choices including late nights, alcohol and smoking. An international study from Flinders University found a 'consistent and significant' increase in the severity of obstructive sleep apnea on weekends, which they have attributed to lifestyle choices and irregular sleep patterns. The findings have prompted fears the true impact of sleep apnea, or sleep disordered breathing, may be underestimated, placing sufferers at greater risk of health conditions including heart disease, depression, dementia and extreme fatigue. The research, published in the prestigious American Journal of Respiratory and Critical Care Medicine, analysed data from more than 70,000 people. It found participants were 18 per cent more likely to have moderate to severe obstructive sleep apnea on Saturdays, compared to Wednesdays. Lead author Lucia Pinilla, from Flinders Health and Medical Research Institute Sleep Health, said changes in sleep schedules, such as late nights or sleep ins, worsened sleep apnea. 'Most clinical diagnostic testing is done on a single night, typically a weeknight, missing the weekend effect we're now calling social apnea,' Dr Pinilla said. The study found sleeping an extra 45 minutes or more on weekends increased the risk of worse sleep apnea by 47 per cent. Men were 21 per cent more likely to be affected, compared to a 9 per cent increase in women. Those aged under 60 had a 24 per cent higher risk of obstructive sleep apnea on weekends. The study offers the first evidence that sleep apnea severity increases on weekends, which senior author and FHMIR Sleep Health director Danny Eckert said was significant. 'We don't yet know exactly why, but alcohol use, lighter sleep, and less consistent use of OSA therapies likely play a role,' Professor Eckert said. He said the findings highlighted the need for sleep assessments to be carried out over numerous nights. 'Relying on a single-night sleep study may miss important variations, leading to underdiagnosis or misclassification of OSA severity,' he said. To combat 'social apnea', Professor Eckert recommended a regular sleep routine and aiming for seven to nine hours of sleep each night. 'Keeping a fixed wake-up time and using your prescribed OSA therapy, even on weekends, and going to bed when you feel sleepy will help ensure you frequently get enough restorative sleep which can help combat the weekend spike in OSA.'

Warmer climate could make sleep apnoea more severe, common, study finds
Sleep apnoea, a condition characterised by having trouble breathing properly while sleeping, could become more common and severe in a warmer future, a new study has found. Obstructive Sleep Apnoea (OSA) is a common sleep disorder, estimated to affect about a billion worldwide. The condition occurs when muscles in the throat narrow the airways, impacting breathing and blood oxygen levels during sleep. The findings, published in the journal Nature Communications, show that one's chances of experiencing sleep apnoea could spike by 45 per cent on days with higher temperatures. The effect is projected to be stronger in European countries. However, chances of these effects in populations of countries with a lower gross domestic product per capita, including India, Israel and Brazil, are higher, the study found. Lead author Bastien Lechat from Flinders Health and Medical Research Institute Sleep Health, Australia, said the study helps "understand how environmental factors like climate might affect health by investigating whether ambient temperatures influence the severity of OSA." The study also projected that the burden, impacts, and costs of obstructive sleep apnoea could double by 2100, under a warming of 1.8 degrees Celsius in global ambient temperature above pre-industrial levels. In 2023, the increased prevalence of sleep apnoea due to global warming was "associated with a loss of over 780,000 healthy life years and 105 million workplace productivity days across 29 countries," the authors wrote. The authors quantified well-being and productivity burden due to sleep apnoea. The overall loss was found to be USD 98 billion, with a workplace productivity loss of USD 30 billion, and a well-being loss of USD 68 billion. Study highlights The study is the first of its kind outlining how global warming could be expected to affect breathing during sleep and impact the world's health, wellbeing and economy, Lechat added. Studies have related sleep apnoea with an increased risk of developing cardiovascular disease and mental conditions, including anxiety, depression, dementia and Parkinson's disease. More than 500 nights of sleep data of 116,620 people from across 41 countries -- a total of about 62 million nights -- were analysed. Data was gathered using a sensor placed under the participants' mattresses. The researchers then compared this sleep data with detailed 24-hour temperature information sourced from climate models. "Globally, higher temperatures were associated with a 45 per cent higher probability of having OSA (obstructive sleep apnoea) on a given night," the authors wrote. Further, "scenarios with projected temperatures (of over) 1.8 degrees Celsius above pre-industrial levels would incur a further 1.2 to 3-fold increase in OSA burden by 2100," the study said. A 2023 study by the All India Institute of Medical Sciences (AIIMS), New Delhi, published in the journal Sleep Medicine Reviews, estimated that 104 million Indians of working age suffer from obstructive sleep apnoea, of whom nearly 50 per cent have it in a moderate or severe form.
