    Over the last decade, drinks containing high amounts of caffeine, sugar, and other ingredients that increase energy have been rapidly growing in popularity. Clearly these beverages are known as energy drinks. Energy drinks have gotten so popular that it is extremely rare to find a convenience store that doesn’t sell a variety of them. Students use energy drinks to cram the night before a test, athletes use them to exercise, party animals mix them with alcohol to drink more than humanly possible, and some people just drink them to stay awake at work after a sleepless night. Red Bull, one of the most popular energy drinks in the market, claim to enhance productivity, concentration, energy and help handle stressful situations. It seemed these beverages were a godsend to overworked employees and sleep-deprived college students. But after a few deaths were linked to the drink, controversy arose. Apparently Red Bull gives you wings, but what other side-effects can these sugary, over-caffeinated drinks cause? Many people have been asking this question lately, wondering how harmful drinking them really is. Despite that consuming a large amount of the drink may be dangerous, as long as people drink energy drinks responsibly they are relatively safe.…

    Overconsumption of energy drinks can lead to caffeine intoxication, which can then lead to heart palpitations, hypertension, nausea and vomiting, convulsions, psychosis, and in rare cases, death. Energy drink company's main marketing focus is to kids, even though the energy drink companies know the harm that the drinks cause on the youth. Although the caffeine from energy drinks provides a quick boost in energy to the consumer, the consumer will crash later in the day from a drop in blood sugar, and if the person consumes these drinks every day in severe cases energy drinks can cause death due to cardiac arrest. Energy drinks should have laws against them to protect the consumer, especially children, from the harmful effects that energy drinks can…

    In contrast, heart rate is increased by the sympathetic nervous system (neurotransmitter: noradrenaline) and the hormone adrenaline circulating in the blood via activation of cell surface receptors in the sinoatrial node - pacemaker) (called beta-1 adrenoceptors). This occurs during exercise or fear. The effect is to increase the rate of ejection of blood by the heart. This means that there will be more blood flow to skeletal muscle (in which exercise causes dilatation of blood vessels), so the skeletal muscle cells are supplied with more oxygen and respiratory substrates used to generate energy in respiration where it is needed. A drug that increases heart rate is called a positive chronotrope, and this is demonstrated in this experiment when adrenaline is used to increase heart rate in Daphnia.…
