Explanation:

Analyze circadian rhythm duration

The term "circadian" comes from the Latin words circa (about) and diem (day). Therefore, a circadian rhythm is a biological cycle that lasts roughly 24 hours (one day).

Analyze sleep deprivation and insomnia

The persistent inability to get enough sleep to feel rested or refreshed the next day is the definition of insomnia. Sleep apnea involves breathing interruptions, night terrors involve sudden awakening with panic, and narcolepsy involves sudden daytime sleep attacks.

Analyze sleep apnea characteristics

Sleep apnea is a sleep disorder characterized by temporary pauses in breathing or shallow breathing during sleep, which often leads to disrupted sleep patterns.
