Intriguing study – more evidence that being smart with feelings is key to success in life. In this case – recovery from illness.
Those with low anger control produced higher levels of the stress hormone cortisol, which was in turn, associated with delayed healing.
While I’m not crazy about the phrase “anger control” (because “control” is the most superficial form of self-management – kind of like someone saying you should “control your wife”), the concept makes so much sense. Feelings tied to danger (ie, stress response) focus our body on short-term problems (fight the lion).
Likely one reason feelings like hope, courage, and compassion speed healing is that they reverse stress.
