This was because the subjects' circadian rhythms - which determine patterns of alertness and tiredness - had been disturbed, creating an effect similar to jet lag.
這是因為人體生理節(jié)奏--決定人機敏性和疲倦性的程序已經(jīng)被打亂了，導致了一個像時差的后果。
He speculates that future studies might reveal whether the same mechanism regulates hunger, sleepiness and other aspects of physiology related to circadian rhythms.
他推測未來的研究可能揭示出這種相同的機制是否也在調(diào)節(jié)饑餓、嗜睡等其他生物周期節(jié)律相關(guān)的方面。
