Hot tub volunteers wanted for over-55s health study

The study will investigate whether hot tub use might enhance cardiovascular, cognitive and muscle function

Researchers in Portsmouth are looking for volunteers to study the potential health benefits of hot tubs for older adults.

The University of Portsmouth is exploring the effects of hot water immersion as an alternative to traditional exercise.

The study will investigate whether hot tub use might enhance cardiovascular, cognitive and muscle function.

Most research to date has focused on younger people but the new study will focus on people aged 55.

Participants will be asked to sit in a 40°C (104F) hot tub for 60 minutes, three times per week, for six weeks.

Researchers will assess the effects of the sessions on various health markers, conduct non-invasive tests and take blood samples.

All data will be confidential.

Researcher Daniel Piccolo said: "Frequent exercise is known to significantly improve health but many people find it difficult to follow exercise routines.

"Growing evidence suggests that passive heating, such as hot water immersion or saunas, can offer similar benefits, thanks to a rapid rise in body temperature."
