Eli5 Why is it that when I’m slightly dehydrated one of my eyelids twitch?



It’s usually one of the lower lids, too. Most often my right.

In: Biology

Pretty sure this doesn’t happen to a lot of people. So, you may have a specific reason for this effect, but it would be very hard for anyone to give a good guess.

That’s weird, it’s been happening to me lately to my left eyelid, but I didn’t know it was because of dehydration

Eye muscles are very small and sensitive to electrolyte changes. Rehydrate and it should
go away
