Nobody knows why we sleep, but we all need to. There are no rules about how much sleep is necessary but on an average an adult sleeps for 7 hours 20 minutes. About 8% of adults are happy with 5 hours or less and 4% want 10 hours or more. Babies need between 14 to 18 hours whereas the elderly need less than they did when young but often take a nap during the day.
If you miss a couple of hours of sleep, no harm is done. You may feel tired and irritable the next day but the body soon makes up for the loss if you try to stay awake night after night, however, you soon begin to behave strangely. You lose the ability to concentrate and your judgment is impaired. You begin to imagine strange things and your behaviour becomes deranged.
There are a number of causes for sleeplessness. Worry and depression are the most common. All kinds of things in the environment can affect sleep—noise, light, cold, new surroundings, etc. Pain in illness can also keep people awake. Many people become addicted to their sleeping pills but sleeping pills do not deal with the causes of insomnia and it is better to avoid them if you can. It is much better to identify the problem and remove it.
On the basis of your reading of the passage, choose the correct option:
Q. If some hours of sleep are missed, no harm is done. What harm is being talked about?
  • a)
    Physical harm
  • b)
    Psychological harm
  • c)

  • d)
    Neither (1) nor (2)
Correct answer is option 'C'. Can you explain this answer?

Here both the physical and psychological harm is being talked about. This is because when we try to be awake night after night we can have these harms but when we just try to be awake for couple of ours a single day no harm would rather happen.

Explanation:

Physical harm:
- Missing a couple of hours of sleep may lead to feeling tired and irritable the next day.
- The body can make up for the lost sleep if it is occasional.

Psychological harm:
- Consistently staying awake night after night can lead to impaired judgment, inability to concentrate, and deranged behavior.
- Lack of sleep can also result in imagining strange things.

Both (1) and (2):
- Therefore, missing out on sleep can cause both physical and psychological harm.
- It is essential to prioritize getting adequate rest to avoid these negative consequences.
