Cold Water Acclimatization - Mental or physical adaptation?
"Acclimatization or acclimatisation (also called acclimation or acclimatation) is the process in which an individual organism adjusts to a change in its environment (such as a change in altitude, temperature, humidity, photoperiod, or pH), allowing it to maintain performance across a range of environmental conditions."
I have my views on the subject but very curious to hear what other people's are.
When people talk about marathon swim training for cold water acclimitisation are they generally talking about adapting mentally for the cold challenge or do people believe their body is going through physical changes that over time make them better able to endure lower temperatures?
Just to clarify I am not talking about things like deliberately gaining weight, I am talking about the simple concept of gradually exposing yourself to longer colder conditions as part of training. Swimming, Ice Baths, Long cold walks, cold showers, shopping in Waitrose etc.
What do people believe?
