If sleeping is so essential, how come we cannot really control it?

Question

Like the way we can control our muscles, or the way we can hold back peeing. How come we cannot control to fall asleep or to wake up?

Answer 1

We can have more control if we learn how and then practice. If I am in a favourable environment I can put myself to sleep when I want most times. Sometimes I can do it even when I am not tired. Although occasionally it won’t work. I haven’t perfected the waking up at a set time yet. I can usually get it to within 15 minutes of the time I choose. I had a friend who could do it to within 1 minute accuracy. People don’t learn, they don’t practice, they don’t get good at it, probably because they don’t know it’s possible.
