Which of the following is NOT true about sleep?
Anettt [7]

Answer:

D. There are three different types of stages of sleep. (There are actually four different stages, the third stage would be deep sleep).

Option A Explanation: <em>True (Children and teenagers need more sleep than adults)</em>

The act of sleeping aids in the body's regeneration and growth. It aids in both the growth of bodily cells as well as the slowing down and relaxation of the mind. According to several medical experts, an adult needs 7-9 hours of sleep every night to perform at their best, while youngsters need between 9 and 11 hours of sleep to do the same. Children obviously require more sleep than adults, despite the fact that adults are much larger than children. Children require more sleep than adults do since they are still going through a development spurt. Children develop physically as well as psychologically. Their body need a lot longer time to function within and experience the best possible physical and mental development. Children's minds are developing rapidly, therefore they require extra time to unwind and comprehend all the information pouring in. In terms of their physical development, kids are gaining weight, height, and even immunity; as a result, the body's cells and tissues require a lot more rest and recuperation time.  

Option B Explanation: <em>True (The body heals during sleep)</em>

Sleeping allows the body to heal more quickly since the brain has less work to complete and can concentrate more on internal bodily issues. i.e., repair and healing. White blood cell production rises as we sleep, aiding in the body's ability to combat germs and viruses more successfully and ultimately reducing the interference that these organisms create in the healing process, resulting in a quicker healing process. While sleeping, the body also produces certain hormones that lower blood pressure, moderate breathing, and relax various body muscles. This procedure can help the wound heal by reducing inflammation.

Option C Explanation:  <em>True (Growth occurs during sleep)</em>

Growth hormone production increases during sleep and lasts for around 1.5 to 3 hours, peaking at the start of deep sleep (NREM sleep). The subsequent peaks correspond to the other deep sleep phases of the sleep cycle. Growth hormone production is influenced by sleep deprivation and delayed sleep start.

Option D Explanation: <em>Not true (There are three different types of stages of sleep)</em>

<em />

Short answer

The stages of sleep are N1, N2, N3, and R.

The waking state is considered as stage W.

More Detailed Discussion

The division of our life into three states—W for waking, S for synchronized sleep, also known as NREM, non-REM, or inactive sleep, and R for REM sleep—might be more important (also called paradoxical or active sleep). There are sub states or phases inside each of the three primary states (WSR).

The two subsets of N1 are N1a and N1b. Between W and N1b, drowsiness (N1a) is a transitory condition. Among light sleep are N1b and N2. N3 stands for deep sleep, however in the previous terminology, N3 included stage 3 and stage 4 NREM sleep.
