What Causes a Caffeine Headache?

Caffeine Molecule
Caffeine's chemical structure

Caffeine, like many other drugs, is physically addictive. That means that when you stop taking caffeine, your body reacts with physical symptoms, sometimes called withdrawals, that can be incredibly painful. One of the most common symptoms of caffeine withdrawal is an intense headache that doesn't seem to go away.

What makes caffeine physically addictive- and how can you quit without experiencing withdrawals?

Adenosine & Your Brain

Adenosine is a chemical that is present in all human cells, and is absorbed by the brain through adenosine receptors. Under normal circumstances, adenosine builds up in its receptors and causes a feeling of tiredness. However, caffeine alters that process by blocking the brain's adenosine receptors from absorbing adenosine; this is what allows caffeine to keep you awake.

When the brain detects that it is receiving less adenosine than it should, it grows more adenosine receptors to compensate. Over time, that means that a person builds up a "tolerance" to caffeine, forcing them to ingest more of the chemical in order to experience the same results.

Quitting Cold Turkey

When a regular caffeine user suddenly stops ingesting caffeine, the brain receives a sudden high dosage of adenosine, caused by the high amount of open adenosine receptors with no caffeine to block them. The first symptoms of caffeine withdrawal are feeling tired or fatigued; soon after, people often report having headaches, migraines, and even flu-like symptoms including muscle aches and more.

How To Avoid Caffeine Headaches

Caffeine withdrawal headaches can be extremely painful and very difficult to relieve. There are many minerals and vitamins that are purported to help minimize caffeine withdrawal symptoms, but the American Psychiatric Association only recognizes one method to treat caffeine withdrawal: tapering, or the process of gradually reducing caffeine intake over a period of time.

CafDetox is the first product on the market that follows the APA's guidelines by using only pure, low-dosage caffeine to decrease a user's caffeine intake over the course of 10 days. You can learn more about CafDetox by visiting CafDetox.com, or click here to purchase a bottle of CafDetox.
