3. Headache
A lot of people use coffee as a “magic potion” because the caffeine stimulates the nervous system and helps you focus on your day-to-day tasks. But in some isolated cases, the most delicious beverage in the world is also used as a form of pain relief, and people consume it to “cure” minor headaches.
However, while caffeine may sound like it works like magic, consuming too much (more than one cup per day) can reverse the effect and give you even more painful headaches throughout the day. Why is this happening, you may ask? Well, the mix of stimulant and diuretic (the two major components coffee has) can be excessive for the brain receptors, and that will lead to a headache.
