The correct answer is C-5.5 times.
A typical sleep cycle lasts for about 90 minutes, and within that cycle, a person goes through different stages of sleep, including light sleep, deep sleep, and REM sleep. On average, a person goes through about 5 sleep cycles in a night. Since each sleep cycle takes approximately 90 minutes, 8 hours of sleep would allow for approximately 5.5 complete cycles.
If a person sleeps for 8hours in one night, about how many times do they cycle through the stages of sleep
A-8 times
B-6.5 times
