A There are reasons you feel so good when you wake up from a long, restful sleep, but for many people getting enough sleep can be difficult. So what is happening when you sleep? Why is it important? And what can you do to ensure you get enough?
B There are five stages of sleep: when you fall asleep, you go into stage 1, which is light sleep and quite easy to be woken up from, then you move into stage 2, 3, and then 4, with each stage getting progressively deeper. After about 1.5 hours you go into another stage called REM (rapid eye movement) sleep, which is when most dreaming happens. This cycle happens around 5 times per night.
C If we take eight hours per night as the average amount of sleep, it means most people will spend a third of their lives sleeping. And it’s not just people; almost all animals sleep and have been doing so for over half a billion years. And considering that evolution has preserved it during this time, sleep must have an important function.
D The main purpose of sleep seems to be to restore energy. According to the National Sleep Foundation, it regulates your immune system, your temperature and your hormone levels, and gives you more energy for the next day. Sleep scientist Matthew Walker adds that sleep is also very important for learning: we need sleep before learning to prepare our brains to learn, and sleep after learning is essential for storing new memories. One of the reasons memory tends to get worse with age might be because people sleep less as they get older, Walker says.
E In his book, Why We Sleep, Walker also says that night owls and early birds may have evolved to be this way. He explains that many years ago when we lived in hunter-gatherer tribes, having a mix of night owls and early birds meant that more people would have been awake more of the time to protect the group, and therefore the tribe would have been more likely to survive. Our sleep cycles do change with age, however. The natural cycle of teenagers is to go to bed later and wake up later, and then, as we get older, this cycle gets earlier and earlier. Given how important sleep is, Walker suggests that perhaps schools and employers should consider these facts when designing schedules.
F Most people need 7-9 hours’ sleep per night, according to Walker. However, two thirds of us get less than this, and there is a price to pay for this sleep deprivation, he says. If you don’t get enough sleep, you will be more forgetful and have problems learning new things, and a constant lack of sleep increases the risk of developing diabetes, heart disease and cancer. Walker considers sleep to be so important that he has started requesting that doctors prescribe it to patients.
G So how do you ensure that you get a good night’s sleep? Walker is against the use of sleeping tablets or alcohol, but at the back of his book he offers 12 tips for sleeping better. These include going to bed and waking up at the same time every day, sleeping in a cool room, doing regular exercise (but not before bed), spending some time outside in natural sunlight each day, and avoiding caffeine in the afternoon or evening – it can take up to 8 hours for the effects of that cup of coffee to wear off.
H There are some other techniques to help with sleep, and a popular one of these is the 4-7-8 breathing technique from Dr Andrew Weil. It’s a quick way to achieve a calm state, and it might help you to fall asleep. It’s quite simple: inhale through your nose for 4 seconds, hold your breath for 7 seconds, and then exhale through your mouth for 8 seconds – do that 4 times. It may need practice, but, according to Medical Daily, if you practise it for 2 months, you will be able to fall asleep within a minute.

Good read! I really enjoyed this article. I personally like reading but find that at night time it puts me to sleep. So whenever I can’t sleep, I just pick up a book and start reading. 🙂

Thanks for your comment.
Great that it worked for you.
I really enjoyed this type of short article. I was studying then living in an English-speaking country. I tended to lose interests in reading English news or browsing social media posts. From today I decide to read from your website to broaden my vocabulary as well as pick up a good habit. Thank you so much for designing such a lovely website!
Thanks for your nice feedback – glad you like the site.
I generally do not read but your article is very short and fascinating. I really liked it.
Glad you enjoyed it.
Article was good and giving an IELTS practice together is a good idea .
Could you explain please explain more about the question 3 I am not get it
Hi Dd. Okay.
The information can be found at the end of paragraph E:
‘Walker suggests that perhaps schools and employers should consider these facts when designing schedules.’
’employers’ = companies
‘these facts’ = the information that came before in the paragrpah: some people are night owls and some are early birds, sleep cycles changes with age (this information shows that people have different sleep cycles; people are not the same).
This equals a suggestion that companies should consider individual differences.
Hope that helps
Really great article that it helped to improve my vocabulary list and also IELTS questions absolutely fantastic.
Thanks Srikanth. Very nice feedback.
There are quite a few more articles to read; if you liked this one, you might also enjoy the one about dreams.

Thanks for your comment, Anes.
Most of the ideas here came from Matthew Walker’s book. Also, his TED talk is really good – you can practise listening and learn more about sleep:
it is good website to improve reading part of IELTS.
Hi, Could you please explain question 4 ?? Both C and E explain this.
Good question – that one is a bit tricky.
The question is looking for evidence from nature about the importance of sleep.
Paragraph C is the correct answer because it has the information that ‘evolution has preserved sleep’; that is the evidence from nature that sleep is important.
While the final sentence in paragraph E does mention ‘the importance of sleep’, it doesn’t give any evidence about the importance (‘given the importance of sleep’ is a reference to the information that has come before). Also, although in paragraph E there is some (possible) evidence from nature, it’s evidence that people being night owls or early birds might have come from nature; it’s not evidence of the importance of sleep.
Hope that helps.
Could you explain question 5 and how does it match B
Sure. Maybe there are a couple of words in the question that need to be understood.
breakdown = (from Cambridge) ‘a division of something into smaller parts’
cycle = ‘a group of events that happen again and again in the same order’.
The sleep cycle is the different parts of sleep that happen in the same order and are repeated through the night.
The question is: Which paragraph contains a breakdown of the sleep cycle?
Paragraph B describes the different parts of the sleep cycle (it is a breakdown); it tells you about the different stages of sleep (within the cycle), and it tells you that this cycle (repeats) happens around 5 times per night.
Hope that helps.
