Caffeine is a natural stimulant that works by stimulating our brain and central nervous system. It can be most commonly taken in the form of coffee, tea, and even cocoa. For a long time caffeine has been demonized for its adverse effects on sleep and anxiety but several studies show that it actually has a variety of health benefits.
One of the caffeine’s best-known qualities is that it can improve energy levels, mood, and even brain functions. This compound works by signaling our brain to block a certain molecule and when this happens the levels of dopamine and norepinephrine increase, resulting in enhanced alertness, reaction time improvement and better short-term recall.
Studies even showed that caffeine intake could lower the risk of developing Alzheimer’s, Dementia and Parkinson’s disease. There might not be any cure for these neurodegenerative diseases but studies in coffee drinkers show a significant decrease in developing them. The studies further show that decaf coffee does not have the same effect which means that it’s actually caffeine that works its wonders in preventing these diseases.
This stimulant has a significant effect on our metabolism and fat burning by increasing their functions. Due to this as well as caffeine’s ability to increase the levels of adrenaline in our blood, caffeine can improve our physical performance and help burn fat. Because of this, as well as its ability to increase fatigue tolerance, considering a strong cup of coffee before working out can lead to better.
Despite the old myths that coffee is bad for the heart, caffeine does not influence the risk of heart disease. Studies even show that it can lower the risk in men and women who drink no more than four cups of coffee per day. Studies with two-four cups of coffee or green tea per day have shown to lower the risk of stroke. Some people might have slightly higher blood pressure due to caffeine, but it generally fades when consumed regularly.
Studies with coffee have also shown that the beneficial compounds found in it, including caffeine, can reduce the risk of type 2 diabetes as well as protect against it. According to a review, each cup of coffee has shown a 7% risk decrease and with each cup, danger of developing this disease drops.
Our liver is one of the most important organs in our body as it carries out a myriad of vital function. That’s why it is important to keep it healthy and studies in coffee drinkers have shown that drinking four or more cups per day can reduce the risk significantly.
Another benefit coffee drinkers can reap from their daily consummation is a lower risk of developing cancer according to studies. It has shown that coffee can protect against cancers such as liver, colorectal and skin cancer by a significant percentage. These cases had demonstrated results when it came to high coffee consumption of over four cups daily.
Some people might be more sensitive to caffeine but in general, it is safe to consume. According to research the safe daily recommended intake of caffeine is 400mg, which corresponds to 2-4 cups of coffee per day. Coffee and teas contain, besides caffeine, a large variety of beneficial antioxidants that together with caffeine’s qualities can improve our health and lifestyle.
