How to stay calm when receiving review notifications? I've been in academia for roughly 8 years now. Wrote quite a few papers. Still, my heart starts seriously racing each time there's an email notifying me of a review for one of my papers. 
Does anyone have any good tips on how to be less stressed out about this?
I've been in Stack Exchange for roughly 5 years now. Wrote quite a few questions and answers. Still, my heart pumps each time there's a notification of a comment for one of my posts. 

No, I don't think you can escape from the fear of being rejected for something you emotionally invest into it. As long as it doesn't affect your health, you may want to feel relax when it's come.

Acknowledge your fear, and tell yourself that that fear is not scary may reduce the stress of not being able to control your fear. The fear from the notification is unavoidable, but the stress from not being able to control your fear is a secondary stress that you can control. Take a breath. Accept the fear. 

If anything, I suggest you to practice mindfulness. It's a technique to not being overwhelmed by our emotions, and has been recognized as an effective way to reduce stress. It has been used in many programs and therapies for stressful people.
