Hello! I'm new here and want to ask question. What is the different between rest and sleep?
Because my lecturer asked this question for my assignment, and I had confused.
thank's ya! your answer will be very useful for me.

can you rest without sleeping? can you sleep without resting?

It might be useful to look at the different stages of sleep.

I can rest without sleep, when I was playing guitar and enjoy myself. Is that called rest?

[stopherlogic]

Rest is a period of bodily inactivity, so while playing the guitar is "chilling out" or something along those lines I wouldn't really define it as rest.

This seems to explain the difference quite well.

rest is cessation of work, exertion, or activityand peace, ease, or refreshment resulting from sleep or the cessation of an activity.
'Sleep' is a natural, periodic state of rest for the mind and body, in which the eyes usually close and consciousness is completely or partially lost, so that there is a decrease in bodily movement and responsiveness to external stimuli. During sleep the brain in human beings and other mammals undergoes a characteristic cycle of brain-wave activity that includes intervals of dreaming.

What is up with that bogus link you put for rest? You get google points for clicks?

Looks like seek went to hide. Thanks mods

Just curious, has anyone figured out the circadion clock thing. I am mostly interested in how plants know what time it is. I had a theory but I am sure it is bannanas

What I am thinking is that certain cells (Let’s call them time factor cells, TFC’s) have a 24 hour life span. These TFC’s produce a factor A while in there live state, and when their life span comes close to the end, they produce a factor B. When factor B is produced, the cell is metabolized and a new one forms to repeat the time clock cycle.
Factor B also signals end of 24 hour period which would initiate response.




Thanks
