It’s no secret that swimming pools have been a hot topic for the past decade, with reports of people becoming ill in swimming pools in countries including the UK, Ireland, Germany and Australia.
But what exactly does swimming pool illness have to do with swimming?
A study published in the BMJ has shed some light on the topic.
“The underlying mechanisms of pool-associated illness are unknown, but the main cause is exposure to high levels of CO 2 ,” study co-author Dr Daniel Bissett, from the University of Liverpool’s Department of Health, said in a press release.
Dr Bissetts team, including scientists from the Royal College of Obstetricians and Gynaecologists, the University College London and the University Health Network, have conducted a study of 5,000 adults in the UK.
They were recruited between 2006 and 2009, and compared the risk of hospital admission to CO 2 levels between 6pm and 6am in the morning.
They also compared the results to data from other studies that measured CO 2 exposure in the same location.
What they found was that people who were exposed to the highest levels of indoor CO 2 were more likely to be diagnosed with swimming pool-related illness.
The team, which is funded by the Wellcome Trust, analysed data on people who had previously been diagnosed with a CO 2-related condition.
In the UK alone, more than 5,600 people died from CO 2 related illnesses in 2017, with 1,800 people suffering from CO 3-related complications.
This study, which was published in BMJ Open, shows that indoor CO exposure may be a contributing factor to the rise in CO 2 associated hospitalisation.
Dr Bressett added that the research suggests there is an association between swimming pool pollution and increased risk of CO-related hospitalisation and death.
The research has been funded by Wellcome trust and the Department of Education.
