The normal human daily cycle of activity is of some 7-8 hours’ sleep alternation with some 16-17 hours’ wakefulness and that the sleep normally coincides 46 the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified.
The question is no mere academic one. The ease with which people can change from working in the day to working at night is a 47 of growing importance in industry where automation invites round-the-clock working of machines. It normally 48 form five days to one week for a person to adapt to a 49 routine of sleep and wakefulness, sleeping during the day and working at night. 50 , it is often the case in industry that shifts are changed every week. This means that no sooner has he got used to one routine 51 he has to change to another, so that much of his time is spent neither working nor sleeping every 52 , one answer would seem to be nicer periods on each shift, a month, or even three months. 53 recent research has shown that people on such systems will revert to go back to their 54 habits to sleep and wakefulness during the week-end and that this is quite enough to destroy any adaptation to night work built up during the week. The only real solution appears to be to hand over the night shift to those permanent night workers whose 55 may persist through all week-ends and holidays.
