Great question! When it comes to stress there are two parts to deal with the stressor (what is causing the stress) and the stress in our body. In regards to dealing with the stress in our body, the book Burnout by Emily Nogoski talks about the importance of completing the stress cycle. What this means is that when you feel stressed, you need to find a way for your body to essentially get rid of it or complete the cycle. This might be through physical exercise, emotionally connecting with a loved one, doing something creative, having a good cry, or deep breathing/meditation.
The best way to deal with stress with vary from person to person, it is important to figure out what works for you! Exercise and connecting with a friend are what work for me!
