Why Coffee Sometimes , Makes You Tired .<br />Has a cup of coffee <br />ever backfired on you? .<br />You get a quick jolt of energy, but then you get sleepy.<br />According to 'The New York Times,' this is due to what researchers call "sleep pressure.".<br />From the second we wake up, our sleep pressure is driving us to go back to sleep later on in the day. .<br />As we go about the day, our body burns energy <br />in the form of a molecule called ATP, <br />adenosine triphosphate.<br />Our cells then generate a byproduct called adenosine, which causes us to be sleepy. .<br />Caffeine is very similar to adenosine on a chemical level, and while we may get a quick jolt of energy from a cup of coffee ...<br />... our adenosine continues to build up and you'll have to pay it back.<br />Caffeine can also lead to dehydration and a spike in blood sugar, which can make you tired. .<br />If you’re sleeping less and you’re stressed, and you rely on caffeine to improve it, it’s just a perfect storm for a short-term solution that’s going to make things much worse in the long term, Dr. Stein, via 'The New York Times'.<br />The solution? <br />Drink less coffee.
