“It’s actually normal to wake up several times per night, but awakenings need to be more than three to five minutes long to be remembered the following day,” says Dr. Audrey Wells, MD, a ...

Polyphasic sleep is the practice of sleeping during multiple periods over the course of 24 hours, in contrast to monophasic sleep, which is one period of sleep within 24 hours. Biphasic (or diphasic, bifurcated, or bimodal) sleep refers to two periods, while polyphasic usually means more than two. [1]
