This is a concentrative breathing exercise meant to help you calm your central nervous system. It's great for times in which you are experiencing stress, anxiety, anger, or fear. It's also best to practice it when you are feeling neutral or good and to do so several times so that when you need it you are easily able to remember and access it.

I felt sleepy after box breathing
I felt sleepy after box breathing box breathing was harder than I thought
More challenging than expected!
I found that holding after exhaling is different from breathing exercises I have tried before which focus on holding breath in. I really enjoyed this challenge and the constant counting helped focus my mind. Thank you.
