The correct answer is eustress
Stress is the emotional response to an unpleasant and uncomfortable situation. It has traditionally been understood as the inner imbalance caused by some external cause (job instability, overwork or any other circumstance that can generate tension). However, stress is not always negative, as there is a positive stress also known as eustress (the Greek prefix I indicates that something is good like euphoria or euthanasia which means good or smooth death).
Positive stress occurs in our body when we react with motivation in the face of a difficulty so that the tension felt is stimulating, as it is considered that overcoming the tension comes with some kind of reward.
