Why is it that sometimes when you take caffeine that only your heart beats faster but your mind stays tired (or becomes even more tired)?
In: Biology
I guess it’s only a temporary central nervous system stimulant and it can’t really replace lost sleep. It might temporarily give your body a boost but if you’ve only had two hours sleep then you’re probably gonna be tired no matter what. Plus, you’re probably gonna crash hard after the initial surge. It’s not a miracle worker 😛
