The problem with anger is that it fires up the emotion centers of the brain, making it challenging to be logical, wrote Emma Seppälä, the science director of Stanford University's Center for Compassion and Altruism Research and Education.
So, while it's okay to be angry, you'll need to calm down a little bit before you can address the situation that's frustrating you. Otherwise, you could say something that's emotionally-charged and potentially insulting.
"Cool your flames and you'll see more clearly and communicate far more effectively," Seppälä wrote. "Breathe, take a walk, distract yourself with a funny movie, meditate, exercise, pray — anything to help you regain your composure but also some perspective."
If you don't have time for any of that, try this breathing exercise.
Then, revisit the situation when you're more calm.
