For small dosage caffeine can have a good effect to our body but if consume too much this substance can have a bad effect. Caffeine substance not just contains in coffee but other plant also contains this substance.
Caffeine is an odorless, slightly bitter, Alkaloid chemical found in coffee beans, Kola Nuts, and Tea leaves. It can be manufactured synthetically in the laboratory. In small amount caffeine acts as a mild stimulant and is harmless to most people. In large amounts, however, it may result in insomnia, restlessness, and anxiety.
Caffeine also raises urination and heart rates and can cause hart irregularities; some researchers maintain that heavy coffee drinkers are more prone to develop coronary heart disease. Caffeine decreases blood flow to the brain, however, and has been used in treating migraine headache. It is also used in treating cases of poisoning by depressants such as alcohol and morphine, and studies suggest that it somewhat increases the effectiveness of common analgesics such as aspirin. By widening bronchial airways, caffeine can help to relieve asthma attacks. In plant, the drug apparently function as a natural insect repellent.
Most of people who crave that extra mug of coffee, tea, or cola drink to pep up a slow day know that each swallow contain caffeine but few realize how potent a drug it is. Caffeine sometimes found with chemically related stimulant knows as theophylline and theobromine, is a drug that act fast. In less than five minutes after you downed that cup of coffee, caffeine has raced to every part of your body; it increase the flow of urine and stomach acid, relaxes involuntary muscles, steps up the intake of oxygen, and speeds up the basal metabolic rate by 10 percent. It also heightens the pumping strength of the heart; but too much caffeine can lead to an irregular hearbeat. Caffeine improves the user's physical coordination; for example, it improves the skills of typists and motorists. But it can also hinder your efforts; It can make a painstaking task, which needs a steady hand and accurate timing, more difficult.
Can caffeine hurt you?
While cramming for final exams, you may stay up all night, and find looking nervously at the sunrise, that your seventh cup of coffee has left you with quivering hands and a grinding headache. No wonder. For most of us, three to four cups of coffee, around 400 milligrams of caffeine, can bring on irritableness, headaches, tremors, and nervousness. If that dose is doubled, the jittery coffee drinker can suffer hallucinations, perhaps convulsions. The fatal dose is 10 grams (or 10,000 milligrams), but to die from a caffeine overdose, you'd need to polish off 67 to 100 cups on a brief sitting. Luckily, our body metabolize this drug rapidly, so that a morning dose of caffeine leaves little trace in the blood stream by evening.
Caffeine can create dependency. Those who drink at least five cups of coffee a day can suffer several days of withdrawal symptoms including nausea, headaches, irritability, and lassitude, if they kick the habit. The person who drinks too much in a big way can experiences "caffeinism," a syndrome characterized by rapid breathing, agitation, mood changes, and heart palpitations. A heavy coffee drinker may develop the habit over a period of time; when these symptoms occur, he or she may not realize that caffeine is the culprit. If you're troubled by anxiety and other symptoms, cut out the caffeine from your diet; even your physician may overlook this syndrome when treating your case of nerves and arrhythmia (irregular heartbeat).
Caffeine may pose other dangers. Although no proof has been found, studies have linked the drug in cola drinks and coffee to heart disease, benign and malignant tumors, pancreatic cancer, and birh defects. Still other studies refute these links. Nevertheless, it's good idea for pregnant women to avoid caffeine as they would avoid any other drug. The effect of caffeine for adult people may not danger because already arrange their habit to drink of coffee. The problem when a child have habit to drink caffeine from their habit drink cola, and many children consume much more than this every day.
