It normally【C5】______form five days to one week for a person to adapt to a【C6】______routine of sleep and wakefulness, sleeping during the day and working at night. 【C7】______, 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【C8】______he has to change to another, 【C9】______much of his time is spent neither working nor sleeping every 【C10】______. One answer would seem to be【C11】______periods on each shift, a month, or even three months. 【C12】______recent research has shown that people on such systems will revert to go back to their【C13】______habits to sleep and wakefulness during the week-end and that this is quite enough to destroy any【C14】______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【C15】______may persist through all week-ends and holidays.
