It's 12:18 p.m., and by now, the glorious effects of your first coffee of the day are probably wearing off. Before you head off to Starbucks for that second cup, think about your poor adrenal glands. Caffeine gives you a mental boost by firing off neurons in the brain (sounds great, doesn't it?), which signals the pituitary to secrete hormones that get the adrenal glands to pump your body full of adrenaline. Over time, all this extra adrenal stimulation can wear out the glands, depleting your defense system, according to Natural News. For those of us who love coffee and all it does for big bursts of focus and creativity, this is lousy news, of course. So until you've got the guts to quit, just tell your adrenal glands you're sorry.
Ever wonder why coffee makes you pee so much more? You likely know caffeine is a diuretic, meaning, something that causes your kidneys to produce more urine. We were wondering if all this extra pee processing was tough on the ol' bladder, however, research has shown that coffee's diuretic effects aren't that much stronger than, say, a glass of water. So unless you're mainlining five cups a day, or you have bladder issues, your lovely ol' excretory system should be able to handle your coffee needs so you can stay perky.
