Scientists Seek Volunteers to Participate in Groundbreaking Hot Tub Study
Researchers at the University of Portsmouth are seeking volunteers to take part in a study examining the potential health benefits of hot tubs for older adults. This study aims to investigate the effects of hot water immersion as a relaxing alternative to traditional exercise and explore whether it may improve cardiovascular, cognitive, and muscle function.
Unlike previous research that has primarily focused on younger individuals, this study specifically targets participants aged 55 and above. Volunteers selected for the study will be required to spend 60 minutes per day, three times a week, relaxing in a 40°C hot tub over a span of six weeks. Throughout the study period, researchers will carefully monitor the impacts of these hot tub sessions through non-invasive tests and blood samples.
To qualify for participation, volunteers must be aged 55 or above and free from serious cardiovascular, metabolic, respiratory, or neurological conditions. Additionally, they should be non-smokers with a body mass index (BMI) falling within the range of 18-35 kg/m². The study is inclusive of all genders.
Daniel Piccolo, a researcher and PhD student at the university’s School of Psychology, Sport and Health Sciences, highlighted the significance of this study. He pointed out that while regular exercise is known to have substantial health benefits, many individuals struggle to maintain exercise routines. Piccolo noted that passive heating methods such as hot water immersion or saunas show promise in offering similar health advantages by raising body temperature rapidly.
He emphasised, “This study aims to determine if similar health benefits can be achieved in individuals aged 55 and older. Participants should be generally healthy, without major cardiovascular or metabolic conditions such as type 2 diabetes. By expanding our understanding of passive heating, this study could offer a feasible and enjoyable alternative to exercise for older adults.”
