Eustress
Eustress is a noun that refers to stress that is beneficial. Stress is a well known English word that refers to mental or emotional pressure, but when we add the Greek prefix E-U, which means ‘well’ or ‘good,’ we get something close to ‘good stress,’ or stress that is, in some sense, helpful. Here’s an example: I found looking after eight dobermans to be a surprising source of eustress. After a week of keeping those hounds out of trouble, watching my two daughters was a piece of cake.
