drinking caffeine can cause headaches.

Question

Caffeine can cause headaches. Caffeine also is something that relieves headaches, which is why it is in a lot of pain medication. the caffeine helps to reduce inflammation, and in headaches the caffeine narrows the blood vessels, which decreases pain. even the withdrawl of caffeine causes headaches because when you stop drinking caffeine after a while, your blood vessels then start to expand again, causing the headache.

Comments

Just from personal experience can I confirm that this is true. Sometimes a person can get the "jitters" too. I think it is vary situations and the amount of caffeine that determines whether or not someone gets a headache.

This article has a good amount of evidence to prove its claim is true but I do believe that caffeine can also be used to relive headaches. Since caffeine is shown as a temporary solution it should not always be relied on for a cure to headaches. Caffeine is seen in a lot of medications and shown to help with lots of symptoms you may see while sick. Although people do not realize that caffiene is addictive and while taking large amounts of it and then cutting back can cause headaches.

Good explanation! But I think there’s more to it, caffeine can help headaches in the short term, but if you use it too often, it can actually cause more headaches over time. This is called "rebound headaches," and it happens when your body gets used to caffeine and then reacts when you don’t have it. Your source is good, but adding one that talks about long-term effects could make your fact-check even stronger!

This article does a good job of supporting your claim. An overconsumption of caffeine can definitely cause a headache but it is accurate that caffeine is in a lot of medicines. Many researchers suggest that caffeine can constrict blood vessels, while alleviates pain during a headache. Plus, regular caffeine consumption can reduce the frequency of certain headaches over time, so in that case a withdrawal of caffeine may trigger headaches for people due to the body’s adjustment to the lack of caffeine.

This claim is true. There are many causes for headaches and caffeine has proved to be one of them. Drinking too much caffeine can constrict the blood vessels in the brain which creates headaches. Dependency on the effects of caffeine in the brain can also create headaches from the withdrawal. https://www.mayoclinichealthsystem.org/hometown-health/speaking-of-health/does-caffeine-treat-or-trigger-headaches

Answer 1

The claim that caffeine causes headaches is true. According to the article “The caffeine connection between coffee and headaches” by UCLA Health, caffeine narrows blood vessels, therefore lessening headache pain. However, a sudden lack of caffeine can dilate blood vessels and thus lead to headache pain. Another article called “Does caffeine treat or trigger headaches?” by Mayo Clinic Health System, supports the claim that caffeine can cause headaches by stating that when caffeine is consumed regularly, the body becomes dependent on its effects. When caffeine consumption is suddenly stopped, the blood vessels that were once narrowed now become enlarged and cause an increase in blood flow around the brain, which causes pressure around the surrounding nerves. This pressure is what causes headaches.

Answer 2

After doing some research this claim seems to be true. The source that was used seems to be pretty reliable giving a good amount of information about caffeine being a source for headaches. I found a source from the Mayo Clinic that talked about how caffeine can cause headaches due to consuming it regularly causing a dependency. When you stop consuming it you can end up getting caffeine withdrawal headaches. This source also mentioned how caffeine can provide relief for headaches as well due to it narrowing blood vessels, which restricts blood flow and alleviates the pain. Overall this claim that caffeine causes headaches is true, but it can also provide relief for headaches as well.

Answer 3

Based on my research, I've come to the conclusion that the claim is true. Neurologist Kelli Tornstorm provided us with credible information and insight as to what exactly happens to cause a headache from caffeine. She states that, "When caffeine is consumed regularly, the body becomes dependent on its effects. And because caffeine narrows the blood vessels that surround the brain, when consumption is stopped, the blood vessels enlarge. This causes an increase in blood flow around the brain and pressures surrounding nerves. This can then trigger what is known as a caffeine withdrawal headache."
