67 Causes of Tension Headaches
Caffeinated Drinks
Although caffeine is a common substance used in many OTC medications to relieve headache, it would actually result in tension headaches if taken excessively. This element blocks the release of adenosine receptors, which help prevent a headache attack in the body. Therefore, it is better to limit the intake of caffeine in some drinks, such as coffee, energy beverages, or green tea. For those people with frequent headaches, avoid caffeine completely can be helpful. If you are a heavy coffee drinker, keep in mind that slow withdrawal would contribute to your tension headaches in the first few weeks. [6]
