Did you know that caffeine is the most widely consumed psycho-active substance in the world? As a beverage, the worldwide consumption of tea is surpassed only by water!

The pros and cons of the stimulant have been debated for many decades. These days, researchers are throwing out so much information left and right about caffeine, who can keep track of whether it's good or bad for you? On the plus side, caffeine has antioxidants and with regular consumption, it can reduce the chance of developing Parkinson's disease and help protect the body against gallstones. It is also argued that caffeine increases your metabolism, thus promoting weight loss (Dave, 2008). Furthermore, the "drug" improves alertness, enhances mood, improves physical stamina, and relieves headaches. On the flip side, heavy daily caffeine use may disturb your sleep pattern and cause nervousness, restlessness, irritability, upset stomach, fast heartbeat, and muscle tremors (Mayo Clinic Staff, 2011). In addition, recent studies have shown that women who drink in excess of one cup of coffee every day are only half as likely to conceive as those who drink less than a cup a day and caffeine consumption during pregnancy is associated with prematurity, poor reflexes, and neuromuscular development (Burchfield, 2001).
In conclusion, caffeine in moderation can have positive effects, while having too much can have serious health effects and can lead to a nasty withdrawal headache.
