FOR many young urbanites, a morning routine is not complete without a cup of joe. Some people also get their caffeine through energy drinks or caffeine pills. While everyone’s tolerance is different, there is a limit to how much caffeine people can have in their systems. Jittery fingers and a racing heartbeat are common signs that you’re over-caffeinated. In rarer scenarios, an overconsumption of caffeine can lead to a state called caffeine intoxication or caffeine overdose. Caffeine intoxication occurs when a person has dangerously high levels of caffeine in the system. It creates a spectrum of unpleasant and severe symptoms, such as trouble breathing and seizures. There are a few cases where people have died from caffeine intoxication. Caffeine intoxication is more than the headache you get from drinking too much expresso. It happens when people ingest an excessive amount of caffeine. The U.S. Food and Drug Administration defines this limit as anything more than 400 milligrams of caffeine daily for healthy adults. This is equivalent to four or five cups of coffee. Consuming slightly more than 400 milligrams of caffeine makes the average adult feel anxious and irritable. The more toxic effects of caffeine intoxication appear when people have 1,200 milligrams, about 12 cups of coffee, in their system. (SD-Agencies) |
