During a research trial, the results of which are published in the journal Biology, healthy volunteers were given a functional MRI (fMRI) scan immediately after bathing in cold water. These scans revealed changes in the connectivity between the parts of the brain that process emotions.


For the first time, a team of researchers has observed changes in how different parts of the brain interact with each other after a personโ€™s body is immersed in cold water. The findings explain why people often feel more upbeat and alert after swimming outside or taking cold baths.

The research team from the University of Portsmouth, Bournemouth University and University Hospitals Dorset (UHD) recruited 33 volunteers for the trial.
