Why do we feel sleepy, tired, and feel like we need to sleep more when we wake up? (Like, is there a special chemical in the brain that causes that?).

Are there any ways to wake up without feeling such things?

    $\begingroup$ It is not tired by sleeping excessively, the question was why do we feel sleepy when we just wake up from being asleep. $\endgroup$ – C. Shockley Aug 15 '16 at 17:29

    $\begingroup$ Let say you are hungry and I stop you in the middle of your lunch. With high probability... you will be still hungry %)) $\endgroup$ – Ilan Aug 15 '16 at 20:29

    $\begingroup$ I don't know if anyone else experiences this, but for me I always wake up six hours after falling asleep (and that's usually as soon as my head touches the pillow). At that precise moment when I wake up, I'm wide awake. Any sooner I feel sleepy and any later I feel groggy. $\endgroup$ – FoldedChromatin Aug 16 '16 at 6:38

    $\begingroup$ It is true I feel more sleepy in a vacation morning when I'd slept early, (with no factor of anxiety or stress) and normally rise on morning; than the end of an extremely busy, anxious, unslept night. $\endgroup$ – Always Confused Aug 28 '16 at 11:24

    $\begingroup$ Probably it is not solely due to lack of sleep $\endgroup$ – Always Confused Aug 28 '16 at 11:28
