@zacksfever: Three liters. That’s roughly what your body needs in a day in this heat, and most people are nowhere near it. You’re losing water all day without feeling it. Every breath carries some out with it. Your skin is losing a bit right now just from sitting in the sun. And that’s before urine and sweat, the losses you can actually notice. The ones you can’t feel we call insensible losses, and the heat here pushes them higher than people think. For someone living with sickle cell this stops being a wellness thing. Their kidneys often can’t concentrate urine the way yours can, so they lose more water on an ordinary day before anything else even happens. Let them get dehydrated on top of that and the red cells get more concentrated, they start to sickle faster, and that’s the road into a crisis. So when I tell a sickle cell patient to keep water on them through the day, that’s me trying to keep them out of the ward. This was from a sickle cell program I spoke at last year. The questions people asked afterward stayed with me. #sicklecell #sicklecellwarrior #sicklecellawareness #sicklecelldisease
