Question

During which sleep phase do you typically experience a lot of thrashing around?

A) NREM sleep
B) REM sleep
C) Deep sleep
D) Light sleep

Answer 1

Thrashing around typically occurs during REM sleep in individuals with REM sleep behavior disorder (RBD), while sleep spindles and K-complexes are associated with stage 2 NREM sleep, and deep sleep is characterized by low frequency, high amplitude delta waves.

Step-by-step explanation:

During typical sleep cycles, large amounts of thrashing around or physical movement do not occur in any of the sleep stages under normal conditions. However, there is a sleep disorder known as REM sleep behavior disorder (RBD), where an individual may experience high levels of physical activity during REM sleep. In contrast, sleep spindles and K-complexes, which are associated with learning and memory, are most often connected with stage 2 of NREM sleep. It is also worth mentioning that activities such as sleepwalking most commonly occur during the deep sleep phase, also known as stage 3 of NREM sleep, but this stage is characterized by low frequency, high amplitude delta waves and does not typically involve thrashing around.
