Headaches
Many studies have found that stress can lead to headaches, which is accompanied by pain in the head, face, or neck region.
A 2015 study discovered that elevated stress intensity was associated with an increase in the number of headache days experienced per month.
Another study evaluated 172 military service members at a headache clinic, finding that 67% reported their headaches were caused by stress, making it the second most common headache trigger.
A smaller 2020 study also showed that stress can lead to tension headaches.
Other common headache triggers are lack of sleep, diet, alcohol consumption, hormonal changes, and more.
