Frequently Asked Questions About Cold Baths
Are cold baths and ice baths the same thing?
In practice, yes. "Cold bath" is the broader term; "ice bath" is often used to refer to colder temperatures, below about 8 °C.
How often should you take a cold bath?
Three to four times a week, for a total of about eleven minutes in the cold. Consistency is what makes the difference—not single, long baths.
Can you take cold baths outdoors all year round?
Yes, with a cooling system. Without cooling, the water heats up to the ambient temperature in the summer and becomes too hot.
Who should be careful?
If you have a heart or vascular condition, high blood pressure, or are pregnant—talk to your doctor first. Never swim alone at first.
