So, I love water. Who doesn't? It's one of the top few drinks known to man.
And so in office I used to drink a lot of water. I thought that's healthy.
Over time, I started developing a throbbing headache. I was very confused, and assumed the worst. Did not want to go to the doctor, cuz I thought it'll pass. But I saw it coming back a few days a week, for almost 2-3 months.
Somehow, I recently read a book on health which asked me not to drink excess water, cuz it washes away minerals. Then I read more, realized if you have too much water, it can lead to swelling up of parts of the brain, which leads to a throbbing headache.
It was an big insight. It's been a couple of days, actively measuring and making sure I don't drink too much. So far, no headache yet (fingers crossed)
