As near as I can tell from the fact that I am sometimes forced into situations where I have to deal with sweat, gradual habituation does... drumroll... nothing.
I am no psychologist. I thought one of the benefits of gradual habituation was that it was in a controlled setting that subject could end at any time with essentially no consequences. This contrasts "sometimes forced in to situations", I also have the impression that these forced situations there is no sequential order of events from the least discomfort to the most, in other words no gradualness(Also perhaps these events start at too high of a stimulus level.)
Finding someone capable of setting up a gradual habituation regiem and having the time to follow through with it are the biggest obstacles to experimenting with habituation regiems in my experience.
An exercise:
Name something that you do not do but should/wish you did/are told you ought, or that you do less than is normally recommended. (For instance, "exercise" or "eat vegetables".)
Make an exhaustive list of your sufficient conditions for avoiding this thing. (If you suspect that your list may be non-exhaustive, mention that in your comment.)
Precommit that: If someone comes up with a way to do the thing which doesn't have any of your listed problems, you will at least try it. It counts if you come up with this response yourself upon making your list.
(Based on: Is That Your True Rejection?)
Edit to add: Kindly stick to the spirit of the exercise; if you have no advice in line with the exercise, this is not the place to offer it. Do not drift into confrontational or abusive demands that people adjust their restrictions to suit your cached suggestion, and do not offer unsolicited other-optimizing.
