Why when you cry do you get extremly tired afterwards?

Crying can lead to fatigue due to the physical and emotional toll it takes on the body. The act of crying triggers the release of stress hormones and depletes energy resources, which can result in feelings of exhaustion. Additionally, emotional crying can be a cathartic release, leaving you drained after processing intense feelings. This combination of physical exertion and emotional release contributes to the tiredness you feel afterward.
