Just five minutes in cold water can boost mood, research shows

The health benefits of cold-water immersion have been closely studied in recent years, thanks to the growing popularity of cold-water swimming. Now new research from the University of Chichester has found that as little as five minutes immersed in cold water can have almost the same benefits as much longer stints, helping provide a quick mood-boosting solution for physically fit people with low mood. The resulting paper is published in the journal Lifestyle Medicine.
