[[Special:MyLanguage/Biphasic|二相]]睡眠也是被常用的回復類型。因爲這種時程有兩個睡眠段落，可以對其中一個中使用鬧鐘，而對第二個不設限制。

*如果由於生活上的不便而無法獲得足夠睡眠時間，[[Special:MyLanguage/E1|E1]]和[[Special:MyLanguage/Siesta|Siesta]]在夜間的主段可能會受到限制。為了彌補失去的睡眠，二相時程會在中午前後安排一個不設定鬧鐘的睡眠。 不過，白天的睡眠時間不應超過約2小時，因為這可能會破壞[[wikipedia:Circadian_rhythm|晝夜節律]]的穩定性或使晚上難以入睡。因此，限制白天的睡眠段落，但在夜間睡眠不設定鬧鐘也是有意義的。

* [[Special:MyLanguage/E1|E1]] and [[Special:MyLanguage/Siesta|Siesta]] may have a restricted nocturnal core if it's impossible to sleep for long enough due to social inconveniences. In order to compensate for the lost sleep, a no-alarm sleep is scheduled during midday. Sleep during the day shouldn't be longer than ~2 hours though, as this may destabilize [[wikipedia:Circadian_rhythm|circadian rhythm]] or make it difficult to fall asleep in the evening. For this reason, it also makes sense to restrict the daytime block of sleep, but leaving the nocturnal sleep without alarms.

*在[[Special:MyLanguage/Segmented|分割]]時程上，可以針對第一個主段使用鬧鐘，而讓自己在第二個主段自然醒來。

* On [[Special:MyLanguage/Segmented|Segmented]], it's possible to use alarms for the first core, waking up from the second one naturally.
