Paradoxical Undressing.
It's a facet of Hypothermia. With both Severe Anxiety & Hypothermia... Our blood gets yanked to our cores. It's a highly useful thing... In hypothermia it keeps vital organs warm enough to survive, in fight/flight situations it prevents major blood loss in the areas we tend to bleed the most in (superficial skin wounds, and wounds to our arms and legs).
The problem is twofold: our limbs do need blood... And the vascular response gets tired after doing it for awhile. So our bodies periodically send Whoomph! Hot Hot Hot blood to all of our limbs.
Which makes us feel like we're suddenly burning up. (This is part of the hot & cold flashes during anxiety, btw.).
If it goes on for too long? Well most people can only feel like you're standing in the deserts of Saudi Arabia wearing a snowsuit for so long before strip strip strip...take the damn snow suit OFF!
In either hypothermia or extreme anxiety...we're not really in our most rational minds. Even SAR workers who
know about paradoxical undressing struggle to not strip off clothes in the sudden heat wave the blizzard has just put on, and when anxiety is up? Survival mode just doesn't lend towards a whole helluva lot of rationality. First anxiety needs to be lowered,
then reason returns.
But, yes. Super common. About 1/2 of all hypothermia vics are found having stripped themselves nekkid as a jay bird, and while I don't have stats on anxiety? I would suspect the numbers are about the same. Survival Mode. It's quirky. Here's some more on that.
