So, I just had to share this with you. This week in CMB lecture, I learned something that validated my sanity (somewhat). I’ve always complained that whenever I am cold, I have to pee constantly. I’ve always thought this was just one of my weird quirks, and no one I mentioned it to could ever give me an explanation either. But we learned in CMB that this is a NORMAL occurrence, and we learned why. Here’s a very brief and “watered-down” version of why alcohol and cold make you pee more:
Certain cells throughout your body are more permeable to water (they can take in water)… for example, cells in the kidney and red blood cells. These cells have lots of Aquaporins on their surfaces. Aquaporins are proteins that form channels across the cell membrane so that water can travel into the cell. To keep it simple, alcohol and cold temperature both INHIBIT aquaporins in various places throughout the body, including the brain and kidneys so that less water is taken up by the cells… meaning that more water is in your bloodstream and more has to be urinated out.
I love these little random, but real-life medical and scientific tidbits. Anyway, I had to share!
Back to studying….
