That is how it started. People that were really into this would get an ice machine like at a hotel to throw ice in the tub. It is just another fitness gimmick with limited use that most people will get and never use. Most people I know with hottubs barely use them once the novelty wears off let alone cold. Most people's diet and sleep is not dialed in enough to worry about an ice bath.
