How Coffee Affects Your Brain

Many people can’t imagine waking up without having a cup of coffee. For some, it’s become a morning ritual. But is it actually beneficial or is it causing harm?

In this article, we’ll discuss how coffee affects the brain.

The Good

Other than tasting great, coffee also has some health benefits. Although not exactly considered a health aid, a cup of java can benefit your brain in a few unexpected ways.


The caffeine that’s in coffee can influence the brain to release certain neurotransmitters. One of them is dopamine, which some refer to as the “feel-good” hormone. This would explain why many regular coffee drinkers experience a sense of pleasure while sipping their morning beverage.


Coffee naturally contains many antioxidants which can help to promote brain health. They can help to maintain and prevent damage to your brain’s blood vessels by encouraging healthy blood flow. The antioxidants found in coffee can also prevent the buildup of free radicals which can damage brain cells.

The Bad

Although many people swear by their morning cup of Joe, coffee does have a negative side. This is increased for those who consume more than the daily recommended allowance.

Side Effects

Mostly caused by the caffeine that naturally occurs in coffee, there are some negative neurological side effects. These can include:

  • Restlessness
  • Nervousness
  • Sleep disruption
  • Muscle twitching


With maintained use, some coffee drinkers can develop an addiction to the caffeine that’s contained in the beverage. This is due to the chemical changes that can occur in the brain with daily consumption. Signs of caffeine withdrawal can include:

  • Low energy
  • Depression
  • Mood swings
  • Headache

Coffee and the Brain Explained

Your morning cup of coffee contains both good and bad qualities. While it can help to elevate your mood and remove free radicals, it can also result in insomnia, restlessness, and caffeine addiction. For your overall brain health, it’s a good idea to realize when too much coffee is simply too much.
