While having an alcoholic drink may not cause a headache in most people, studies have shown that alcohol can trigger migraines in about one-third of those who experience frequent headaches. Alcohol has also been shown to cause tension and cluster headaches in many people.
It’s a vasodilator, meaning it widens blood vessels and allows blood to flow more freely. Vasodilation may cause headaches in some people. In fact, headaches are a common side effect of vasodilators like blood pressure medications. Additionally, alcohol acts as a diuretic, causing the body to lose fluid and electrolytes through frequent urination. This fluid loss can lead to dehydration, which can cause or worsen headaches.
Sleep deprivation can be detrimental to your health in many ways, and may even cause headaches in some people. For example, one study compared headache frequency and severity in those who got less than six hours of sleep per night and those who slept longer. It found that those who got less sleep had more frequent and severe headaches.
However, getting too much sleep has also been shown to trigger headaches, making getting the right amount of rest important for those looking for natural headache prevention. For maximum benefits, aim for the “sweet spot” of seven to nine hours of sleep per night.
Drink Caffeinated Tea or Coffee
Sipping on beverages that contain caffeine, such as tea or coffee, may provide relief when you are experiencing a headache. Caffeine improves mood, increases alertness and constricts blood vessels, all of which can have a positive effect on headache symptoms.
