In one experiment in our laboratory at Stanford University,a volunteer who had only been allowed four hours sleep the night before had his eyelids taped open(uncomfortable,but doesn't hurt).He was asked to press a button every time an irregular strobe light flashed.For a few minutes he tapped the switch after each flash,on average every six seconds.Then a bright flash surged into his pupils but he did nothing.
“Why didn’t you press the switch just now?” we ask.
"Because there was no flash"the young man replied.
The machine we used to monitor brain activity showed that at the very moment the light had flashed the young man had unwittingly fallen asleep,with his eyes wide open ,for two seconds.If he had been behind the wheel of a car,those two seconds could mean disaste.
Social pressures to work more and at odd hours have reduc reduced our sleep time over the past century by about 20 percent.Add to the mix our own era’s drive to have and do it all work,family,sports,hobbies and there is very little time left for rest.I consider sleep deprivation a national emergency.
