Question

Quizplus · Accepted Answer

Stress has been identified as one of the major triggers of headaches, but not everyone who experiences stress gets headaches. Therefore, it is likely that a stressful problem will produce headaches, but only in individuals who are susceptible to headaches or already suffer from them. This is supported by research that shows that those who are prone to headaches are more likely to experience them during times of stress.
