Use three questions
What is the claimed benefit? What are the possible harms or costs? What would I stop doing to make room for it? An activity that is enjoyable still does not need to be described as a cure.
Allow a modest conclusion
You might decide that an activity is pleasant but not essential, or that you need professional advice before trying it. There is no obligation to choose between total enthusiasm and total rejection.
