Several sources suggest that cold baths (60–75 degrees Fahrenheit) were preferable to ice baths. Physiotherapist Tony Wilson of the University of Southampton said that extremely cold temperatures were unnecessary and a "cold bath" would be just as effective as an ice bath.[24] Another agreed that a mere cold bath is preferable to ice baths which are "unnecessary."[19] A third report suggested that cool water (60–75 degrees Fahrenheit) was just as good as cold water (54–60 degrees Fahrenheit) and that eight to ten minutes should be sufficient time, and warned against exceeding ten minutes.[21]
