Webcomics - When you stand up too fast (2021)

You know what, I've never really looked into what that "condition" is called. Quick Google search and it turns out it's called "orthostatic hypotension (postural hypotension)." It's a form of low blood pressure caused when standing up too fast after sitting or laying down for a long period of time, and it's often the result of being mildly dehydrated, low blood sugar, or being too hot. It's really only a worry if it happens extremely often and/or causes more concerning issues like blacking out and fainting.

Yah this used to happen to me too. One time it was go bad I was blind for like a full minute. Needless to say I didn't go to school that day.
