The Importance of Control and Predictability in Stress Mitigation

Having a sense of control and predictability can make stressors less stressful. Studies with rats show that when rats have control over running on a wheel voluntarily, they get the benefits of exercise, while rats forced to run on a wheel experience the negative effects of severe stress. It is crucial to select stress mitigation techniques that work for each individual, as what works for one person may not work for another. Additionally, stress management techniques should be practiced regularly, rather than saved for occasional use, for optimal effect. Social support, outlets for frustration, and social support are also beneficial in stress management, but it's important to understand that what works for one person may not work for another, and that the context in which these techniques are used is crucial.
