Do you have any references for this donny? I've been looking up information and don't see a lot regarding 'loss of cranium fluid' related to sauna use. Also though, are you referring to sinus mucous and such when referencing the clearing of the head feeling? I have found some medical notes in regards to intercranial CFS reduction, but not so much as to make it alarming unless one might be practicing weight loss long term.

Here`s an interesting link below related, although not referencing intercranial CFS loss per se, to many facets in regards to sports and hydration and dehydration.

There is alot of info. in there. It is particularly good I found in exploring how it pertains to distance running hydration.
