Know what you are putting in your body and how it works. This is a good, quick, simple explanation of how caffeine affects the brain and the body, but what this video fails to mention is what happens once caffeine unbinds (everything that binds will eventually unbind) from the adenosine protein receptors…all the accumulated adenosine circulating in your blood stream that was unable to bind to its natural receptors due to bound caffeine, binds to all the receptors at once when caffeine is released, thus causing you to get very tired very quickly as opposed to over time. We call it “crashing”. This is why energy drinks have names like “5hr energy” because caffeine doesn’t stay bound much longer than 4-5hrs. The more caffeine you consume, the more unbound adenosine builds up in your brain, the harder you are likely to crash once all that caffeine wears off and unbinds from the adenosine receptors. Make sense?
83% of americans drink coffee and 90% consume caffeine on some level on a daily basis. i’m in the minority. i’ve never had a cup of coffee and i haven’t had a soft drink in 4yrs. i don’t take medications, some of which contain caffeine (i.e. excedrin). i axed unnatural and added sugars almost a year ago (june 1st to be exact), which eliminates chocolate , another source of caffeine, from my diet; so my body is pretty void of caffeine save an occasional tea when i travel internationally. most people i know will admit that they can’t function without it. which begs the question: how did we function before coffee/caffeine? i survived college and grad school without it, so i know it can be done. but i guess there is really no incentive to. after all i’ve never heard of anyone OD’n on caffeine? so drink up i guess! just thought i’d share the science project that is in your morning cup of joe.
