Some people drink coffee for taste, others drink it for both taste and the stimulant in it, caffeine. People who need coffee for the caffeine, usually need more than one cup a day. The effects of caffeine only last about 6 hours.

Caffeine is considered a drug because it is a stimulant. It’s effects include increased levels of dopamine, higher levels of energy, increased heart rate, high blood pressure, and it can cause withdrawal symptoms. Caffeine is safe in small doses. For example, the CDC reports that 4-6 cups of coffee or 380-570 mg of caffeine per day can be safe. Exceeding this could be harmful.  The CDC also reports that over 570 mg of caffeine in a day can cause the person to experience symptoms like changes in alertness, “feeling wired”, stomachache, confusion, breathing issues, and fever.

Caffeine also has a positive side. The CDC states on their website that it can prevent liver cancer, and mouth and throat cancer. A study from Harvard University shows that caffeine may decrease suicide thoughts and boost long term memory.  Although many people repeat this information, coffee or caffeine  does not stunt human growth.
