We all know that the normal human daily cycleof some 7-8 hours' sleep alternating with some 16-17 hours' wakefulness andthat, broadly speaking, the sleep normally coincides with the hours ofdarkness. Our present concern is win how easily and to what extent this cyclecan be modified.

The question is no more academic one. The case,for example, with which people can change from working in the day to working atnight is a question of growing importance industry where automation callsinsistently for round-the-clock working of machines. It normally takes fromfive days to one week for a person to adapt to a reversed of sleep andwakefulness, sleeping during the day and working at night. Unfortunately it isoften the case in industry that shifts are changed every week; a person maywork from 12 midnight to 8 a.m. one week , 8 a.m. to 4 p.m. the next, and 4p.m. to 12 midnight the third and so on. This means that no sooner has he gotused to one routine than he has to change to another, so that much of his timeis spent neither working nor sleeping very efficiently.

One answer would seem to be longer periods oneach shift, a month, or even three months. Recent research by Bonjer of theNetherlands, however, has shows that people on such systems will revert totheir normal habits of sleep and wakefulness during the week-end and that thisis quite enough to destroy any adaptation to night work built up during theweek.

The only real solution appears to be to handover the night shift to a corps of permanent night workers whose nocturnalwakefulness may persist through all weekend and holidays. An interesting studyof the domestic life and health of night-shift workers was carried out byBrown. She found a high incidence of disturbed sleep, digestive disorder anddomestic disruption among those on alternating day and night shifts, but noabnormal occurrence of these symptoms among those on permanent night work.
