Winter is coming, or so i wish. Today it's 30+ degrees celcius and i'm totally floored! I feel inflamed from top to bottom, can't stand up and feel completely exhausted. It started last night with a terrible hayfever reaction, i woke up with bloodshot eyes, clogged sinuses and non stop sneezing. Quercetin and feverfew brought me some relief but on top of that i took 5mg cetirizine this morning.... bad choice as it increases vasodilation. Anyone else here who wishes summer ends rather sooner than later? And what do you do to control heat triggered OI / POTS? I'm staying with my parents for a few weeks in the Netherlands but they don't have air conditioning (which is rarely needed in this depressing country anyway), at home i usually crank up the AC and lay down until i feel better. I'm thinking about taking cold showers. Caffeine works great too as vasoconstrictor but it always leaves me overstimulated and in the end it worsens the OI / POTS because of its diuretic effect. Perhaps some extra sodium?
