Does hitting the critical level of an IPhone 6+ affect its battery life?

Hello, I've been stressing a little bit lately over my iPhone 6+. I have stupidly let it hit critical battery 2 times over the past week and a half-ish. So my question is, does hitting the critical level of the battery affect its lifespan? Does it deteriorate the battery every time it reaches its critical level?
