![]() ![]() Rubbing a few drops of diluted peppermint essential oil on the forehead or temples may be effective. Menthol can numb the skin and reduce pain. In one study, researchers showed that applying a frozen neck wrap to the neck reduced pain in participants who were experiencing migraines. ![]() Icing an area constricts the underlying blood vessels and slows the transmission of nerve signals. ![]() ![]() Sometimes even minor dehydration can lead to an intense headache. That said, taking pain medication more than two to three times a week may lead to a headache known as a medication overuse headache, or a rebound headache.ĭehydration causes the brain to shrink, which can set off pain receptors in the skull. Medicines that are available over the counter, such as ibuprofen, aspirin, and acetaminophen, contain compounds that block pain signals and ease most headaches. However, people trying to cut back on caffeine can use several other remedies or tricks to reduce caffeine withdrawal headaches. The quickest and easiest way to relieve a caffeine-withdrawal headache is to consume caffeine. People who consume caffeine regularly tend to develop more of these adenosine receptors, making them more likely to develop a headache when they stop drinking caffeine. Blocking these receptors can potentially decrease the spread of pain in the head. This reaction is significant because blood vessels tend to enlarge before the onset of certain types of headache.Ĭaffeine also blocks adenosine receptors in the brain, which are pain modulators. With regular caffeine consumption, blood vessels become familiar with this constriction.Ĭaffeine reductions can trigger a rebound effect, causing blood vessels to widen. This is because caffeine has a vasoconstrictive effect, meaning it narrows blood vessels and reduces blood flow. One analysis reported that 50% of people experience a throbbing, widespread headache during caffeine withdrawal. However, caffeine may cause or contribute to headaches in a number of ways.
