According to USA Today, about 83% of Americans drink at least one cup of coffee a day. The amount of caffeine in an 8oz cup of coffee varies depending on how it is brewed and the type of coffee bean; but, on average, one cup contains about 95mg of caffeine. Last month, a teenage boy died from consuming too much caffeine in a two hour period of time, which caused a heart arrhythmia. This is because caffeine signals the release of norepinephrine, which increases the heart rate and may cause irregular heart beats, seizures, and dehydration. Other symptoms of caffeine overdose are headaches, dizziness, and vomiting.
Obviously, most people can consume coffee every day without worrying about any type of major side effects. The takeaway message is that everything should be consumed in moderation, and an excess of any substance can be potentially dangerous and severe. Bingeing on caffeine, alcohol, sugar, etc, can be harmful, and we should teach our kids to be careful with everything that they ingest
