Dealing with Postural Hypotension and POTS

hey ! so i was diagnosed with postural hypotension and possibly pots a couple years ago but i wasn’t told a lot on what i can do to help. currently when i shower i’m having to sit down or get out before i can fully wash out my conditioner because i feel faint. i was wondering if there was anything i should be doing to prevent this or is this just how i am. i domake sure my showers aren’t too hot as i know that’s a major trigger but yeah thanks x
