Energy drinks are used all over the world. 30-50% of teenagers consume energy drinks, these are not regulated by the FDA. Energy drinks are primarily a combination of glucose and caffeine. They also contain a chemical called dopamine. Dopamine is one of the main chemicals responsible for our happiness. When the effects of caffeine are eliminated, the amount of adrenaline in your body also slows down. Once you stop consuming caffeine, the amount of dopamine in your body slows down. Glucose is a sugar that the body uses directly as energy for basic body functions and activities. Too much glucose can lead to high cholesterol levels and fat production. Most of the sugar in energy drinks is fructose (high fructose). But caffeine has a stronger effect than sugar in energy drinks. It is more effective because it is stronger than sugar. There is no evidence that sugar can give you more energy or even keep you awake longer. Sugar is commonly mistaken by people for a quick energy boost when in reality it has never been proven. Experts say caffeine is the most used drug in the world, many people have access to caffeine through: coffee, energy drinks, soda, etc. Caffeine is an odorless bittersweet drug found inside coffee beans, cocoa beans, tea leaves, and kola nuts. The word coffee comes from the Arabic word "quhwah", which means bittersweet. Coffee is grown in many countries such as Brazil, Colombia, Kenya, Jamaica and Ethiopia. Long ago it was told in an old story that a young Ethiopian was watching his family's goats when he noticed that some goats were eating coffee beans from a coffee plant. He observed that goats that ate coffee beans were much livelier than goats that did not eat them, leading him to believe that… middle of paper… beats per minute. Heart rate, or pulse, refers to how many times your heart contracts and relaxes per minute. As you age your heart rate changes. According to Medline plus, Newborns from 0 to 1 month: 70 - 190 beats per minute, Newborns from 1 to 11 months: 80 - 160 beats per minute, Children from 1 to 2 years: 80 - 130 beats per minute, Children from 3 to 3 years: 4 years: 80 - 120 beats per minute, children from 5 to 6 years: 75 - 115 beats per minute, children from 7 to 9 years: 70 - 110 beats per minute, children from 10 years and adults ( including the elderly): 60 - 100 beats per minute, Well-trained athletes: 40 - 60 beats per minute. Heart rate can be measured at the wrist, groin, neck, temples, back of the knees, or on the top or inside of the foot. You can't use your thumb when picking someone's poop because the thumb has a pulse of its own, so it can interfere with patients.
