How Does Caffeine Affect Your Health?

“Should I be drinking as much caffeine as I do?” “Should I be decreasing my consumption of coffee if it is decreasing my health?”

I am assuming that since you are reading this, you are wondering the same thing. I love coffee, and I am sure you do as well, so it would be a struggle to stop drinking coffee even though it would be for health reasons.

To some caffeine consumers, this may not seem like a big deal, but to others, it could be a big problem. Caffeine might not necessarily be dangerous, but if it is over-consumed, it could most definitely become a hazard to our health.


If you rely on your cup of coffee to get you out of bed each morning, to give you some extra energy in the afternoon, or maybe even just to enjoy a nice warm cup, you are not alone! Most adults consume some type of caffeinated beverage every single day.

What we will be covering in this blog post:

  • What is caffeine?

  • Health benefits of caffeine.

  • Health concerns of caffeine.

  • What should be the max consumption of caffeine each day?


What is Caffeine?

Before I started in the coffee industry, I always thought that caffeine was another term for coffee. Every time someone would say caffeine, I just assumed they were refereeing to coffee, but I quickly realized that caffeine is in coffee, but is not the liquid itself.


Caffeine is not only found in coffee, but other drinks such as: tea, energy drinks (monster, bang, Celsius, etc…) Each drink has different amounts of caffeine affecting how our body reacts to each drink, but today we are talking about coffee.


Caffeine is a stimulant that is naturally found in the leaves and plants of coffee. When consumed, it is well absorbed into the body. That is why when you consume a cup of coffee, it only takes at the most an hour, and you are energized again. For some people, caffeine affects them differently therefore they may feel a boost of energy sooner than an hour.



Health Benefits of Caffeine

The more caffeine you consume and the different forms of caffeine you consume can affect how your body responds to this stimulant, but some consumers react to caffeine differently than others.

There are some aspects that can affect how much caffeine is in a cup of coffee. For one, the different brewing methods of coffee can affect how much caffeine is in a cup. 2oz of espresso is going to have more caffeine than 2oz of French press coffee.


Certain brewing methods are higher concentrated in caffeine (Espresso), increasing the caffeine amount. A cup of coffee typically has around 200 milligrams of caffeine. The more caffeine a food or drink item contains, the more side effects you may experience.

To your surprise, caffeine has many health benefits. Since caffeine is absorbed into the body, it can block adenosine, which is the brain-signaling molecule in our body. As it blocks adenosine, it increases other molecules such as dopamine, and norepinephrine which benefits the increase in your mood and brain function.



Are you looking to lose weight? Try drinking some coffee! Due to caffeine's ability to increase the central nervous system’s function, this may increase metabolism by up to 11%, which increases fat burning by up to 13%. Let's start drinking some coffee!

As caffeine boosts our energy, it can enhance our exercise performance. During this increase in performance, it can improve muscle contractions along with endurance decreasing fatigue. Even better, it may protect against heart disease, and diabetes.

There are even more benefits of coffee such as: increases gut health, skin protection, liver protection, longevity, and decreased cancer risk.


Health Concerns of Caffeine

The things that concern us most may not be the caffeine we consume each day, but it could potentially affect our health in the future depending on our consumption. Caffeine consumption is so called safe, to a certain extent. If you are consuming more than 400mg of caffeine in one day, that’s when I would become concerned. It’s hard to think that more than 80% of the world consumes a caffeinated beverage every single day.



Even though coffee has not been associated with many extreme health issues, it could become a concern for those who consume a large amount of it. Caffeine has been associated with anxiety, and restlessness, making it difficult to sleep. Along with those that drink coffee in excessive amounts, it could reach a point where your body is used to that much caffeine, and if you stop drinking it immediately, you will begin to get migraines, headaches, and acheiness.


Even though coffee doesn’t raise any major concerns, it still may increase some concerns for those who drink considerable amounts of it causing many of these things to occur. Even though we love our coffee, it sometimes is best to moderate our consumption to prevent further damage to our body by increasing heart rate, which can then cause other issues to occur.


Max Recommended Amount of Caffeine One Should Consume In one Day

The max amount of caffeine a person should consume everyday may vary from person to person due to the tolerance for each one's health, and body but according to the U.S. Department of Agriculture (USDA) and the European Food Safety Authority (EFSA) consider a daily intake of 400mg of caffeine to be safe. Obviously, if you would consume more than the recommended amount of caffeine, it won’t be extremely concerning until you reach 600-900mg intake. Then we might all be getting concerned for you!

What you should be taking from this is that caffeine is healthy for you in more ways than one, so grab your coffee mug, and fill it up. If you don’t drink coffee, I am sure you can learn to enjoy it as much as all the other coffee lovers out there, but also, we can remember to drink our coffee in moderation. It probably wouldn’t be the best to drink 3 pots of coffee ourselves in one day, “as much as we would like to!”
