How to handle stress?

My colleagues organizing a conference are under heavy stress. So much that it seems to impact their performance. I remember the deadlines we had to meet when we worked for a pitch. Often for days deep into the night. And the way we kept stress at productive levels. For that you have to know what you are dealing with. When stress becomes too much you feel first a certain alarm, then resistence and in the end you feel completely exhausted. A certain degree of stress helps your performance. If it gets too much it impacts your judgment: you don’t know anymore whether you are doing the rights things or are trying to do the things right. It turns positive energy into negative energy: you become unfriendly, angry or aggressive. Stress finally stops your mind totally from functioning. It leaves you behind helpless: time for sick-leave.
