Sleep researchers have found that people can make themselves wake up at a given time simply by deciding to do

so before they go to sleep. Scientists took two groups of

volunteers and, at nightfall, told one group that they would

be woken at 6 a.m. and the other that they would be woken

at 9 a.m. The sleepers' levels of the hor’one

adrenocorticotropin which is known to cause spontaneous

awakening, were then measured. In each group, there was a

rise in the levels of the hormone one hour before the

volunteers expected to get up. The three-hour difference

between the rise in hormones in the two groups suggests that

the body can be programmed to wake up on command.
