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
C-5.5 times
D-10times
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.
To determine approximately how many times a person cycles through the stages of sleep in 8 hours, we need to have an idea of the average duration of one sleep cycle. On average, a sleep cycle typically lasts about 90 minutes. Therefore, in 8 hours (or 480 minutes), a person would have approximately 480/90 = 5.33 cycles.
Since it's not possible to have a fraction of a sleep cycle, the person would likely have completed either 5 or 6 full cycles. So the closest answer is C-5.5 times, although it is not an exact representation of the number of sleep cycles.
To determine the number of times a person cycles through the stages of sleep during 8 hours of sleep, it's important to understand the sleep cycle duration. On average, a sleep cycle lasts around 90 minutes.
Given that 8 hours is equivalent to 480 minutes, we divide that by the average sleep cycle duration of 90 minutes.
480 minutes / 90 minutes = 5.33 (approximately)
Therefore, a person would cycle through the stages of sleep around 5.33 times during 8 hours of sleep.
Since the options provided are whole numbers, we can round this value to the nearest whole number.
The closest whole number is 5.
So, the answer is C-5.5 times.
