Many people take in their daily dose of caffeine with their first cup of coffee or sips of soda. While a moderate amount of caffeine consumption is safe, experts warn that too much caffeine can pull too much water from a person's body and lead to dehydration. An elevated amount of caffeine can also negatively affect sleep patterns and blood pressure. Make sure to enjoy the right amount of caffeine by following the recommended guidelines and staying below 400 milligrams of caffeine per day.
