Most professionals agree that caffeine is safe when consumed in moderation. Caffeine can also interfere with our normal sleep pattern and make our body disregard our biological sleep rhythm. However, high doses of caffeine can cause anxiety, dizziness, headaches, and nervousness. On the other hand, many people feel that caffeine increases our level of alertness. However, others don’t get that high from caffeine and choose to stop consuming it. It can improve mood for a temporary period of time. However, most caffeinated beverages are processed enough to disguise its bitter taste.Ĭaffeine gives most people an “injection” of energy, something like a “ high“. In its natural form, caffeine has a very bitter taste. It’s considered a stimulating substance because it activates the central nervous system, increasing the level of alertness.Ĭaffeine is found in tea, coffee, many sports drinks, painkillers, and other over-the-counter medications. We can also artificially manufacture caffeine and add it to certain foods and drinks. Three days in a row, 0.25mg from the first day, 4.1mg for the second day, 66.2mg new from the third day.Caffeine is a substance that occurs naturally in many plants’ leaves and seeds. If you did the same thing two days in a row, at midnight on the second day, you'd have 4.1mg leftover from the first day, and 66.2mg new from the second day. Now we'll again add 25mg to make 93.6mg at 9pm. 89 each hour, we can dispose of these 12 hours without a calculator: 137.3mg at 3pm, 68.6mg at 9pm. That will decay to 125.2mg at 8am and 111.5mg at 9am, when we add 163mg more for a total of 274.5mg.ĩpm is 12 hours away from 9am = 2 half-lives away from 9am. If we assume it is metabolized at a constant rate, the idea is that, every hour, there is 11% less caffeine in your body than there was an hour ago.Īssuming you start out clean, at 5am you ingest 42mg.Īt 6am, 37.4mg from 5am is still in your body, and you ingest 25mg more, for a total of 62.4mg.Īt 7am, you have 55.6mg remaining of the 62.4 that was in you an hour ago, and you ingest 85mg more, for a total of 140.6mg.
