Headache is defined as a pain arising from the head or upper neck of the body. Although not all headaches are the same, they all share at least one thing in common – they cause pain and may also cause other unwanted symptoms, including nausea and vomiting. There are many different types of headaches, like those caused by exposure to certain substances. Some people are sensitive to caffeine and may react with headache following caffeine consumption. On the other hand, caffeine also has been shown to be an effective treatment for several headache types.
Energy drinks contain about the same amount of caffeine as a cup of coffee. Furthermore, the caffeine content of energy drinks is declared on the label, so consumers are informed accordingly. In general we do not recommend energy drinks to persons sensitive to caffeine.
