Horack stresses that ice baths aren’t suitable for those with circulation disorders or diseases, such as Raynaud’s syndrome or peripheral vascular disease. Additionally, those who are pregnant, have a history of frostbite, open wounds, recent surgeries, or heart problems should skip ice baths. 

“Prolonged exposure can also result in heart palpitations and other cardiovascular events due to the constriction of blood vessels, rise in heart rate, and stress hormones,” Horack says. 

If you decide to take an ice bath, it’s vital that you pay close attention to the water temperature, as you could experience hypothermia or frostbite if the water is too cold. Be sure to always consult with a doctor before deciding if ice baths are right for you.
