Refreshing or Burden?


Are you looking for a stimulant that will help you perform better at work and in the sports field? When you wake up in the morning, smell the coffee.


Whether it's a hard espresso in a small cup, a milk, soft latte in big cups or a Turkish coffee mis. Millions of people around the world regularly drink coffee. Drinking coffee was probably started in Ethiopia, but the main breakthrough was in the Arab world 1500 years ago. He went to Europe from Turkey. The first coffee shop in England was in Oxford and was opened in 1650 by a Turk.


The active ingredient in coffee is, of course, stimulant caffeine. Does caffeine really keep you awake and focus your attention? Does it lose effect if you take it every day? What happens if you miss your daily dose?


Caffeine is also said to affect physical performance. The World Anti-Doping Agency puts it on the banned list of athletes before and after.


I Love Coffee, I Love Tea…


How many of us can't do the right job until we have morning coffee? Those who prefer tea should not pretend not to take caffeine. The leaves, seeds or roots of about sixty plants contain caffeine. Caffeine acts as a pesticide in plants.


Coffee and tea are not the only nutrients we receive caffeine. Many carbonated drinks also contain a significant amount of caffeine. A large glass of cola has a caffeine equivalent to about a cup of tea or half a cup of coffee. It contains some amount of chocolate and other cocoa products. There are also caffeine pills used by students who try to stay awake during long working hours. Some brands have caffeine equivalent to two cups of coffee.


Caffeine quickly mixes into the blood directly from the stomach wall and small intestine. Most are absorbed 45 minutes after taking your last sip. If you're a caffeine madman, you probably have constant caffeine in your body. When you eat and drink something containing caffeine, about half of it disappears within five to six hours. Until then, you'll probably have drunk some more. It's easily addictive and creates withdrawal syndrome until the first dose in the morning.


Caffeine Effect:


Caffeine acts as soon as it gets into your blood. It inhibits a "calming" chemical called "adenosine" in the brain. Our body naturally produces adenosine. The more you accumulate during the day and the more concentrated it becomes, the more you need to rest. Bedtime adenosine tells your body to sleep. Adenosine also dilates blood vessels leading to the brain to increase blood flow during sleep. When the caffeine molecule comes into contact with the brain cell, it settles in the region of the cell membrane that is separated from adenosine. That means adenosine can't do its job. Caffeine keeps you awake when your full sleep is coming. It narrows the blood vessels leading to the brain, so the heart has to pump more challenging and faster blood to meet the demand. The whole process also promotes adrenaline production. This is not very good news. If you get used to it like a lot of drugs, you may only need to consume caffeine to maintain normal functions.


How Much Caffeine Can Kill You?


A cup of coffee contains about 100 mg of caffeine. People in the UK and the United States usually take 200mg to 400mg. Caffeine is a poison. The lethal dose varies from person to person, but the average dose is 15 grams. To get this much caffeine, you need to drink 150 cups of hard coffee in a few hours. It is almost impossible to die with caffeine from drinks, but deaths have been found with excessive caffeine pills.


If you have a gram of caffeine in your veins - from 10 cups of coffee - you'll probably feel terribly tense, restless and uneasy, your heart beats like crazy. In reasonable quantities, it makes you more alert and careful.


Athletes also Caffeine?


Athletes around the world are reluctant to use too much caffeine. They do not want to be dependent on high amounts of caffeine because they can be banned again. The caffeine ban was lifted in 2004, but caffeine is still on the list. The International Olympic Committee also put a limit on caffeine. Before the match, 5 or 6 cups of hard coffee may cause disqualification.


A new investigation has recently appeared. Asker Jeukendrup, professor of Exercise Metabolism at the University of Birmingham; compared performance of cycling racers who drink glucose and caffeine blended water and drink only water. Most caffeine-glucose mixture worked.
