Some people have them when they are tired, some people if they don’t sleep enough, some people have headaches if they didn’t drink enough water that day, etc. Did you know that headaches are one of the main reasons why people miss days at work or school or visit a doctor? According to the latest statistics, provided by the National Headache Foundation, more than 28 million Americans suffer from migraines alone. And that’s a big number – don’t you agree? As we said, there are many different causes for headaches, from the cold to premenstrual syndrome, it can be difficult for sufferers to understand what kind of headache they are experiencing and how to manage their condition. The most common headaches are caused by these common reasons: vascular problem (high blood pressure, toxic overload, etc.), muscle contractions (tension, stress, etc.) and inflammation (infection).
