Coffee is one of the world’s most popular beverages.
Thanks to its high levels of antioxidants and beneficial nutrients, it also seems to be quite healthy.
Studies show that coffee drinkers have a much lower risk of several serious diseases.

Coffee can help people feel less tired and increase energy levels (1Trusted Source, 2).
That’s because it contains a stimulant called caffeine — the most commonly consumed psychoactive substance in the world (3).
After you drink coffee, the caffeine is absorbed into your bloodstream. From there, it travels to your brain (4).
In the brain, caffeine blocks the inhibitory neurotransmitter adenosine.
When this happens, the amount of other neurotransmitters like norepinephrine and dopamine increases, leading to enhanced firing of neurons (5, 6Trusted Source).
Many controlled studies in humans show that coffee improves various aspects of brain function — including memory, mood, vigilance, energy levels, reaction times and general mental
2.Lowered risk of Type 2 Diabetes
Those who consumed 6 or more cups per day had a 22% lower risk of diabetes. From the Archives of Internal Medicine (link). A recent review of research conducted by Harvard’s Dr. Frank Hu showed that the risk of type II diabetes decreases by 9% for each daily cup of coffee consumed. Decaf coffee decreased risk by 6% per cup.

3. Coffee and liver cancer

Italian researchers found that coffee consumption lowers the risk of liver cancer by around 40%. Some of the results suggest that people who drink three cups per day might have a 50% lower risk.
Also, a 2019 literature reviewTrusted Source concluded that "coffee intake probably reduce the risk of liver cancer."

4.Coffee Could Help Your Hair Grow

In a 2007 study published in the International Journal of Dermatology, researchers found caffeine could be a potential hair growth stimulant for men with androgenic alopecia, a common type of hair loss. In fact, the growth of the hair follicles that were treated with caffeine increased 46 percent and the life cycle of the hair was extended by 37 percent.

5. Coffee and heart health

One 2012 study concluded that drinking coffee in moderation, or consuming around two 8-ounce servings per day, may protect against heart failure.
People who drank moderate amounts of coffee each day had an 11% lower risk of heart failure than those who did not.
One 2017 meta-analysisTrusted Source found that caffeine consumption may have at least a small benefit for cardiovascular health, including blood pressure.
Some studies, however, found higher levels of blood lipids (fat) and cholesterol in people who consumed more coffee.
