    Because caffeine doesn’t work that way people. If you are already tired the coffee will NOT make you more alert it just prevents you from becoming more tired for a short period.

    When you drink coffee and feel hyper or more awake you are feeling the effects of the sugar. If you don’t use sugar, you are feeling the placebo effect.

    DRINK WATER

      Correct on how caffeine works, but sugar doesn’t cause hyperactivity, that has been disproven. It’s likely because caffeine is a stimulant so it’ll make your heart beat faster so you might feel more hyper.

      As you said, water is very important as well. Dehydration can make you feel sleepy!

        That’s only sort of correct. It’s only true if you narrowly define hyperactivity as some very specific condition. The studies clearly say that people can experience a “sugar rush” after consuming sugar. The problem is that “sugar rush” is exactly what most people mean when they say hyperactivity. Hyperactivity as in activity that becomes hyper. Hyper as in “above or excessive”, activity as in “doing stuff”. So, “doing excessive stuff”.

            Your meta analysis link is about mood, and not energy levels.  I know in layman’s terms most people conflate the two, but this is a scientific paper so they’re not the same.  And your other link is an article by someone mixing medical terms with layman’s terms to come up with something incorrect. This is why people are losing trust in science, it’s because of stuff like this where people misinterpret scientific results to try to get as many views as possible.
            You know people can easily do this experiment for themselves right?  In fact, I do it most days at about 2:30.  As my blood sugar drops after lunch and I start to get tired and unfocused I will often have a piece of fruit or small piece of candy.  Do you really need a scientific paper to see there is something askew with what you are saying?  If so, here is your scientific paper:

            https://pubmed.ncbi.nlm.nih.gov/3820066/.

            The sugar snack condition was associated with significantly higher tension after 1 hr, and a pattern of initially increased energy and reduced tiredness, followed 1 hr later by increased tiredness and reduced energy.
