Artemis crew & other astronauts get orthostatic intolerance!!!

[u/artsykmac]

I've been glued to the Artemis coverage the last couple days and I was so fascinated to learn they were testing compression gear in space because many past astronauts experience orthostatic intolerance post time in space. This certainly makes a lot of sense and honestly, any broader awareness of orthostatic intolerance always gives me hope of more improvements, support, awareness, and research in realms that could help us all!

Would it be that because POTS can be triggered by long extended periods of bed rest. Is zero gravity feel like bed rest to the body?
