Can Coffee Help a Headache or Make It Worse?

Before reaching for the medicine cabinet when you have a headache, have you considered a cup of coffee? Some feel relief after just a few sips, while others find that their headache gets worse. The effects of caffeine depend on the amount consumed, your regular caffeine habits, and the type of headache you are experiencing.

Caffeine in coffee affects receptors in the brain associated with a substance called adenosine. Blocking these receptors can influence how pain is perceived and may provide relief in certain cases, particularly at the beginning of a migraine.

Caffeine can also enhance the effects of certain pain relieving medications, which is why it is included in some products designed to treat headaches. However, drinking coffee is not an automatic substitute for medical treatment, and it does not help everyone.

When Might a Cup of Coffee Help?

If you regularly drink coffee and it does not cause unpleasant side effects, a small cup at the beginning of a headache may help. It is generally better to drink it relatively early in the day so that the caffeine does not interfere with your sleep at night.

It is also a good idea to drink water alongside your coffee rather than relying on coffee as your only source of fluids. Dehydration can cause headaches or make an existing headache worse.

When Can Coffee Make a Headache Worse?

Large amounts of caffeine can cause headaches, trembling, a rapid heartbeat, nervousness, and nausea. For those who experience migraines, caffeine can sometimes provide relief on one occasion and act as a trigger on another.

Drinking coffee in the evening can also interfere with sleep. Being that insufficient sleep is a well known trigger for headaches and migraine attacks, the coffee intended to relieve today's headache may indirectly contribute to the next one.

The Headache That Appears When You Skip Your Coffee

If your headache tends to appear in the morning, on weekends, or on days when you skip your usual coffee, caffeine withdrawal may be responsible.

Daily caffeine consumption causes the body to become accustomed to it, and therefore suddenly stopping can lead to headaches, fatigue, irritability, and difficulty concentrating.

In this situation, drinking coffee may provide temporary relief, but it can also maintain the body's dependence on caffeine. If you want to reduce your caffeine intake, it is generally better to do so gradually rather than stopping all at once.

Watch for Caffeine Hidden in Medications

Before drinking coffee together with a pain reliever, check whether the medication already contains caffeine. Combining several sources of caffeine can result in consuming more than you intended.

Frequent use of pain relieving medications, particularly those containing caffeine, can also contribute to recurring headaches.

The Most Important Rule

If a small amount of coffee occasionally relieves your headache and does not interfere with your sleep, it may work well for you. If however you need coffee every time a headache begins, find yourself drinking increasing amounts, or develop headaches whenever you skip it, it may be time to reconsider the habit.

A sudden and unusually severe headache, or a headache accompanied by weakness, confusion, difficulty speaking, fever, neck stiffness, or changes in vision requires urgent medical attention.

Headaches that occur frequently also deserve proper evaluation rather than simply another cup of coffee.
