Why Coffee Sometimes , Makes You Tired .
Has a cup of coffee ever backfired on you?
.
You get a quick jolt of energy, but then you get sleepy.
According to 'The New York Times,' this is due to what researchers call "sleep pressure.".
From the second we wake up, our sleep pressure is driving us to go back to sleep later on in the day.
.
As we go about the day, our body burns energy in the form of a molecule called ATP, adenosine triphosphate.
Our cells then generate a byproduct called adenosine, which causes us to be sleepy.
.
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 ... ... our adenosine continues to build up and you'll have to pay it back.
Caffeine can also lead to dehydration and a spike in blood sugar, which can make you tired.
.
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'.
The solution?
Drink less coffee.
