If making a cup or multiple cups of coffee is a daily habit, you may be interested to learn more about some facts surrounding caffeine that many people aren’t aware of. You may be able to see caffeine in a different light and alter how you consume it after reading the facts below. 

Caffeine Can Improve Focus 

Studies have shown that consuming caffeine can lead to an enhanced ability to concentrate better and for longer. Therefore, consuming moderate quantities of caffeine can help you to focus on tasks like revising for exams, writing papers, and any other kind of work that involves mental concentration. 

Furthermore, caffeine can be an effective way to keep your mind awake and alert when it comes to long drives and working night shifts. You can also strategically use caffeine to overcome the post-lunch hump where many people feel fatigued after lunch when at work. 

You Can Make Caffeine More Effective With Less

The more you consume caffeine, the less effective it becomes. This is because your body gets used to consuming certain quantities of caffeine and it’s able to adapt which causes you to feel the effects less and less. 

This is one of the factors that lead to many people exceeding the daily recommendation of 4 cups of coffee per day as their bodies need more caffeine to feel the effects. 

However, one of the ways that you can utilize caffeine to boost your energy without having to increase the doses is by consuming it less. Reducing your caffeine intake to 200-300 mg per day can be a great way to make caffeine more effective so that you can experience the mental boost more regularly. 

For example, if there’s a certain time of day where you need an energy boost, save most of your caffeine for that period. For some people, this will be the first thing in the morning and for others, it could be in the afternoon. 

Consuming caffeine in daily doses that exceed 400 mg can lead to heart palpitations, muscle twitches, stomach aches, and anxiety. So, saving the caffeine for when you need it could be the best way for you to get the most out of your coffee. 

According to CoffeeVerdict.com, too much coffee can lead to anxiety for people already susceptible to the mental health condition. However, anxiety can also occur from consuming too much caffeine that exceeds 400 mg. 

Extreme Doses of Caffeine Can Be Fatal

Caffeine being consumed at excessive doses can lead to death by stressing the cardiovascular system. This is because caffeine can affect your blood pressure, nervous system, and heart rate. 

A lethal dose of caffeine is approximately 10 grams, which equals around 40-50 cups of coffee in a day. Therefore, it’s highly unlikely that you’ll experience fatal effects as it requires an extremely high dosage. The average cup of coffee can contain between 40 and 150 mg of caffeine. 

Caffeine can also be found in workout supplements, energy drinks, and certain medications. So, keeping tabs of our caffeine intake from all sources is always a good idea to ensure you know how much you’re consuming. 

Caffeine Can Enhance Athleticism

Studies related to caffeine and the effects on physical performance have been documented for decades. Over the years, research suggests that caffeine can lead to enhanced endurance and power. 

This is because caffeine has been found to affect your muscles by providing them with another energy source in addition to glycogen. 

You can figure out what caffeine dosage is best for your body based on your weight. Divide your body weight in pounds by half and multiply it by three.

For example, if you weigh 160 lbs, you’d divide 160 by 2 to get 80. 80 multiplied by 3 is 240 which means 240 mg would be the ideal caffeine dose to boost your athleticism. 

For most people, they’ll be able to get their caffeine intake approximately right by drinking a large cup of coffee or two. 

Sensitivity to Caffeine Can Be Hereditary

When you consume caffeine, the body gradually breaks it down over 8-14 hours where it’s metabolized and excreted through your urine. Since it’s a metabolic activity, it can be affected by your genetics.

Therefore, if your parents can consume large quantities of caffeine and not experience the stimulating effects as much as others, it’s likely that your body will react to caffeine in the same way. 

That’s why some people are naturally able to consume more caffeine and not experience the potential side effects compared to others. Whereas others have to cut out caffeine 8 hours before going to bed as it can interfere with their quality of sleep.

People Can Suffer From Caffeine Withdrawals

Caffeine withdrawals are real and have now been identified as a mental health issue. The Diagnostic and Statistical Manual of Mental Disorders includes information on how reducing or quitting caffeine suddenly can lead to certain effects on the body. 

If you’ve been consuming caffeine regularly and suddenly stop your intake altogether or drastically reduce your consumption, it can cause side effects within 24 hours. These withdrawal symptoms can include fatigue, headaches, poor mood, and problems focusing. 

A common sign of being too dependent on caffeine is if you wake up in the morning with fuzziness and a feeling of irritability until you have your first cup of coffee.

If you find that your mood in the mornings is particularly bad until you drink coffee, it may be a good idea to gradually reduce your caffeine intake. 

Cutting down on caffeine over slowly over a week or two is the best way to ensure you avoid the aforementioned withdrawal symptoms. 


Hopefully, you’ve been able to learn something new about caffeine and can have a different perspective on its uses. You can use the info found in this post to tweak the way that you currently consume caffeine to make sure you’re able to use it in ways that enhance your life.
