We have all been there. Fatigue and exhaustion are sometimes too much to deal with. If you are on a very busy schedule, coffee's often the only thing keeping you going. But what exactly is going on when you drink your 3 cups of coffee in the morning before heading out? How coffee affects the brain is a topic that many seek out eventually. Is coffee healthy for you? Does it have any lasting effects? Today at Coffee Testers, you will learn how coffee affects the brain. This is an important topic for any coffee drinker to know more about. 


When talking about coffee and how it may affect your brain, it is important to know that many of these affects come from the caffeine inside the coffee. Studies have been done to determine whether caffeine can affect your sleep. There have been connections between drinking coffee everyday and it affecting your sleep quality.

Of course, these effects are less noticeable in regular coffee drinkers. Another factor in coffee on sleep come in the age of the user. If you drink coffee every day, taking a day break from coffee can even help improve your sleep. Not consuming any caffeine later in the day may also help with sleeping.

​Mental Health

If you drink enough caffeine, it may help improve both alertness and concentration. Coffee and caffeine works to stimulate the central nervous system in a small manner. So, don’t expect to see major improvements. There are enough changes to notice a difference though.

You will have to intake at least 75 mg of coffee to see any type of changes. Coffee seems to only help reduce sleepiness when you are suffering from lack of sleep. Caffeine is also been proven to help with memory performance during repetitive tasks. This should be taking lightly though as having too high intake of coffee may be counterproductive and lower your performance. 


For those suffering from neurodegenerative disorders, coffee can help keep their brain functioning. Overtime, our brains begin to get slower and cognitive function waivers. Drinking coffee may be able to slow down this process. Some studies also show that drinking coffee may be helpful in reducing the chance of getting Alzheimer's Disease.

This area is still under heavy research.


Scientists have gone so far as to prove that there is no correlation between coffee and dependence or addiction. Stopping consumption of coffee immediately may result in some withdrawal symptoms, but it is not severe enough to support addiction.

Drinking enough coffee every can lead to a habit, but nothing more. Getting rid of any type of withdrawal symptoms is relatively easy. To avoid this, simply weaning off of coffee and caffeine is required. 

​Caffeine on a Chemical Level

​To get a bit deeper on how coffee affects the brain, let’s take a look at how caffeine is structured chemically. The way caffeine works is it attacks adenosine receptors in our brain. Adenosine receptors are chemicals that make us sleeper. Caffeine prevents these receptors from making us sleepy when we drink coffee. As a result, our brain will go into overdrive and produce more adenosine receptors to fight against the caffeine that you are in-taking. This leads to more caffeine being needed to keep you awake. This cycle repeats and is the main reason for any type of withdrawal symptoms you may experience.
