strongest known risk-factor for depression is said to be a lifelong history of stress. According to researchers, early-life stress—depending on its intensity, timing, and other specific features—triggers a threefold increased risk of adult depression. Stress early in life has also been shown to increase a person’s “behavioral susceptibility” to stress later in life—increasing stress vulnerability. Therefore, it would stand to reason that if you had a stressful childhood—especially early childhood—it could be helpful to get serious about developing stress-management strategies and implementing them consistently. Researchers believe this information may lead to more effective therapies for depression.
