My dear Anil

I hope everything at your end is fine. I have learnt that you have started being sleep deprived due to various reasons. It is really very sad to know. There may be some valid reasons. However, I am sure if you change your life style, you can remain healthy.

First of all, I would say that sleep deprivation may be called the mother of all diseases. Leaving the reasons behind it aside you must think more of changing your daily routine. For instance, you must go to bed and rise at fixed times. Eat a balanced diet. Avoid junk food, avoid eating street food. Take plenty of water. Dwell more on eating your homemade food. Play for some time in between doing your homework. Don’t view television for I longer hours. Avoid sitting before the computer for hours together and in one posture. Snatch a few minutes in between, if you have to use it, and stretch your body. Avoid the effect of any peer competition. Stop giving a long rope to unrealistic goals.

I am sure if you pursue your goal with a strict regularity you’ll enjoy a sound sleep. You’ll also succeed in your goals.

Yours sincerely

Question 4.
(a) Phrasal verbs are “multi-word verbs”. These verbs consist of a basic verb + another word or words. The other word (s) can be prepositions and/or adverbs that modify or change their meaning.

• pull off : Manage to do something difficult or tricky/to steer or turn a vehicle off the road
• roll down : roll down (something) or roll (something) down : to move (something) down especially by turning handle
• head for : to go or cause to go (towards)

Question 5.
Read the concluding part of the article on whether we get enough sleep these days.

Concluding Part of the Article

SUMMARY

Sleep is very important for one’s health. Without it we can invite health problems, like heart disease, diabetes, obesity and depression.

Stanley Coren, noted professor of psychology and author of‘Sleep Thieves’, says that not sleeping enough can affect one’s immune system. He says that the immune system works best when one is sleeping. Then natural killer cells are generated. These are produced in the bone marrow and found in the blood and lymph fluid. They are the part of the body’s defence mechanism against viruses etc, even cancer.

In a study conducted in Turkey it was found that after 24 hours of sleep deprivation these natural killer cells declined by 37%. In another study in the U.S.A. this percentage was 72%. This activity returns to normal when we begin to get proper sleep. But sleep deprivation does more damage to our immune system.

Dr. Michael Sole, a Canadian cardiologist, says that there is a higher rate of heart failure among people with sleep disorders and sleep disturbances. He emphasises that C-reactive protein is tjie evidence that indicates the heart disease risk.

Researches in various universities all over the world have discovered that sleep loss can reduce the body’s ability to regulate hormones etc. In a study at the University of Chicago sleep from eight hours a night was reduced to four hours. They noted changes in bodies. Sleep disturbances disturbed glucose in tolerance and insulin resistance causing heart diseases. Dietician Ramona Josephson notes that insufficient sleep may effect three hormones contributing to obesity. Increased hormones resulting from sleep loss make us eat more.

Sleep is important in keeping waistline trim. It also ensures a balanced brain activity. During sleep brain neurotransmitters get replenished. In the absence of sleep these brain chemicals become depleted. This leads to emotional disturbances like depression, anxiety, sadness, anger and irritation.
