The consumption of caffeine, in whatever form, has always been an acceptable world-wide method to give a person that much needed "pick me up". A recent case was reported, however, of a 17-year old waitress, Jasmine Willis, who was sent to the hospital after drinking more than three times the recommended daily amount of caffeine with a high temperature and heart palpitations.

Studies have shown that caffeine consumed in large amounts over extended periods of time can lead to a condition called "caffeinism." This usually leads to a variety of unpleasant physical and mental conditions which range from simple headaches, nervousness, and insomnia to more severe cases of peptic ulcers and other gastrointestinal problems.

A study was recently conducted regarding the effects of coffee on reducing tiredness while increasing alertness. A team from Bristol University have found out that the levels of alertness among coffee drinkers were almost the same as those who weren't.

Does it mean that caffeine itself has little or no benefits at all for those who regularly take it? There have been studies which delved into the physical benefits it has on people. In addition to increasing one's metabolism and giving a person a perceived feeling of less fatigue, it has also been suggested that coffee can decrease the onset of Parkinson's disease and keep the mind sharp into old age.

The moderate consumption of around four cups of coffee has been recommended as being perfectly safe. So the next time the urge for an extra cup of coffee tries to overwhelm you, just keep in mind: everything in moderation.
