What's wrong with drinking coffee? That is easy - caffeine. Each cup contains an amount equal to about two pinches of salt. That doesn't sound like much, until you realize that it is one-third of the amount given by doctors as a heart stimulant. With three cups of coffee you are getting a dose of caffeine calculated by scientists to be medically effective for making a weakened heart work as hard and fast as a normal heart. When a heart is ready to quit, and won't pump another beat without the help of caffeine, maybe such a measure is justified. Are you sure your heart is ready for a synthetic jolt three to six times a day?
1. Effects of Coffee on the Human Body: Many coffee drinkers say they can't do without it as a pick-me-up during the day. But let us see what really happens after that coffee break. Dr. Rolf Ulrich, in his book, "Coffee and Caffeine", reports that after coffee consumption, mental tempo rises first, and speed of association increases, but there is a noticeable decrease in the quality of work being done. In test examinations it was seen that the subjects finished quicker, but that false conclusions were more frequent. Reliability and accuracy definitely took a beating as a result of a coffee pep-up.
The physical result is the same. Caffeine raises muscular output temporarily, but in severe physical demands of longer duration, the muscular output decreases. As a famous scientist has said, "Coffee acts like a spur, which drives a horse to do its best, but cannot replace oats. ". That is the whole problem in humans - many of them do expect coffee to take the place of "oats". They pass up a solid breakfast because they can get by with coffee. The stimulating and exhilarating affects coffee produces is usually followed by a loss of energy and a feeling of unsteadiness. No matter how we look at it, coffee takes more from the body than it gives. All coffees contain caffeine but in varying amounts. Fresh ground coffee is the most potent in caffeine. Instant coffees contain half as much and decaffeinated coffees contain about one third as much. It is imperative that a shooter refrain from drinking coffee before and during the shooting session and be moderate in coffee consumption when not firing.
2. Are you considering a change of pace drink, like tea? Before you do, read the following:
It is not generally known that tea has larger amounts of caffeine and tannic acid (the two most detrimental ingredients) per weight, than coffee. Caffeine in tea leaves is about three percent in ratio of one to two percent in coffee. The general effects of caffeine are cerebral, cardiac and diuretic (copious urination) stimulation. As to tannic acid, tea leaves have about ten percent while coffee berries have only about five percent content. Tannic acid, when brought into contact with mucous membrane, acts as an astringent and diminishes its secretions. It coagulates albuminous substances and thus hardens animal source food matter in the stomach with which it comes in contact. It also leads to more rapid clotting of the blood when absorbed into blood circulation. There is evidence of liver damage from extensive use. In solution, it is unstable and should not come in contact with metals. Since coffee is made about twice as strong as tea in liquid form, a strong cupful of either will contain about two grains of caffeine and over three grains of tannic acid.
3. A shooter should stay away from the colas. Cola drinks, in addition to other soft drinks, contain that well known perk-up ingredient, caffeine. The bottles of some brands contain a listing of cola contents which should serve as a reminder. Know them and avoid them while shooting.
