Taking responsibility for stressful situations can bring relief as you regain a bit of control over your life.
For example, studies in nursing homes have shown that giving the elderly responsibility for everyday decision making, like choosing meals or activities, had numerous positive effects on their lives. Specifically, it increased activity, happiness and health while cutting mortality over the course of the study in half.
Interestingly, when staff encouraged them to solve certain tasks, health indices increased. But when the staff helped solve tasks, they decreased. Without actually taking responsibility for their tasks, nursing home residents wouldn’t get the benefit of stress reduction.
