Waking Up Less Sleepy
If you are like most people, then you wake up tired even after a long night's rest full of sleep. Even with 8 to 10 hours of sleep, a lot of people wake up tired. So, people take stimulants, such as caffeine and sugar, to help them wake up in the morning.
This situation got me thinking. It would NOT be evolutionary advantageous to be sleepy after waking up with a full night's sleep. So, why are we so sleepy after waking up?
My theory is that wild animals do not wake up as sleepy as people, because as soon as wild animals wake up they are immediately looking for predators that might be stalking them and they are immediately looking for food to eat. On the other hand, people living in civilized societies typically do not have these concerns, therefore they do not get a rush of adrenaline the moment they wake up in the morning that wild animals receive.
So, the obvious solution for people is not to consume stimulates to wake up faster; but instead, people should develop a stimulating environment to wake up faster, such as exercising or doing an exciting and/or stressful activity as soon as they are awake.
