This boost is beneficial in so many different situations, it’s no surprise that your local coffee shop is booming with business daily.

Scientifically, caffeine acts as a stimulant that works on the nervous system. This works to decrease fatigue which in simple terms makes you feel more awake.


2. Increases Mental Alertness

Caffeine keeps you focused and with a boost to your mental function, it can be a direct result of being able to perform certain tasks better! This is a benefit that everyone can agree with.

Caffeine is in energy drinks and pre-workout formulas too. People drink these for a quick, strong burst of energy. They’re usually in carbonated beverages or powder forms mixed with water.

A stimulant such as caffeine also works to increase your reaction time. This means that your alertness also makes you much more aware of your surroundings. Think of a baseball heading towards your face – that extra boost from the Red Bull you just had could stop a nasty bruise!

Stimulants are great for increasing the buzz of the nerves in your body. It acts as a wake-up call to the nervous system making it easier to avoid danger.


6. Contains Antioxidants

Funnily enough, caffeine is an antioxidant. The acids and other scientific components in caffeine act to flush out your system. Ever chug your morning coffee because you’re late and then you really have to pee? The coffee is moving through your body like a diuretic.

If you’re feeling fancy that day, reach for the organic coffee brand off the shelf. Organic coffee can hold even more antioxidant and diuretic properties, increasing your ‘flushing out’ experiences.


7. Promotes Healthy Liver Function

Coffee lowers the chances of liver issues. Studies have shown that people who already have liver disease and drink coffee regularly are less likely to experience scarring and further damage.

Surprisingly, drinking coffee daily can reduce the risk of death from liver disease. The numbers are up to 15% decrease with one cup of coffee, whereas this shoots up to 71% with four cups of coffee a day. This is a result of coffee filtering through the liver.


8. Reduces Chances of Developing Type 2 Diabetes

Drinking coffee can even reduce the chances of getting type 2 diabetes by producing sugar/glucose. Caffeine works to support the pancreas by regulating blood sugar levels. It’s said to decrease the chances of diabetes later in life.

Not only is it helping your pancreas, but as mentioned, its antioxidant properties also boost the function of insulin in your body. The pairing of sugar balancing and antioxidant-producing properties makes drinking coffee a healthy option!


9. Lowers Risk of Heart Disease

Caffeine is said to make your heart healthy. And no, we aren’t referring to giving you heart-racing feelings after you’ve downed two in a row. The ingredients in caffeine support heart health, which reduces the chances of stroke and heart disease.
