Lesson 19-1 The stuff of dreams

It is fairly clear that the sleeping period must have some function, and because there

is so much of it the function would seem to be important. Speculations about its nature

have been going on for literally thousands of years, and one odd finding that makes the

problem puzzling is that it looks very much as if sleeping is not simply a matter of

giving the body a rest. 'Rest', in terms of muscle relaxation and so on, can be achieved

by a brief period lying, or even sitting down. The body's tissues are self-repairing and

self-restoring to a degree, and function best when more or less continuously active. In

fact a basic amount of movement occurs during sleep which is specifically concerned

with preventing muscle inactivity.
