1
In today's fast paced world, a good night's sleep has become somewhat of a luxury.
2
It has fallen down on our list of priorities behind work, chores, social time, and entertainment.
3
Functioning on less sleep has even become some kind of badge of honor.
4
We brag to our friends, how little sleep we got last night, like it's something to be proud of.
5
But sleep should become our top priority.
6
It’s a vital part of life as important to your physical and mental health as food and water.
7
One of the biggest problems with lack of sleep is that people don't even know they are sleep deprived.
8
Studies show that over time, people who are getting five hours of sleep, instead of seven or eight, begin to feel that they have adapted and got used to this sleep pattern.
9
But if you look closely at how they actually do on tests of mental alertness and performance, they are functioning on a sub-par level.
10
Stimulants like caffeine also aren’t enough to override your body’s profound need for sleep.
11
Now let's look at some side effects that you'll have to deal with when being sleep deprived.
12
1. It makes you dumb Sleep plays a critical role in thinking and learning.
13
Lack of sleep hurts these cognitive processes in many ways.
14
It impairs attention, alertness, concentration, reasoning, and problem solving.
15
This makes it more difficult to learn efficiently.
16
During the night, your brain is busy processing information from the day and forming memories.
17
If you are sleep deprived, your ability to learn and retain new information may be impaired.
18
This may not be news to anyone who has pulled an all nighter, cramming for a test only to find the facts and figures they knew at 2 a.m. could not be recalled the next day.
19
To put it simply, without adequate sleep, your brain has a harder time absorbing and recalling new information.
20
2. You'll gain weight Remarkably, sleep loss may also be a contributing factor to obesity.
21
Firstly, it makes you too tired to get enough exercise.
22
Secondly, you're more inclined to over eat, as it affects two hormones that control your hunger: ghrelin and leptin.
23
Ghrelin signals your brain that it’s time to eat.
24
When you’re sleep deprived, your body makes more ghrelin.
25
Leptin, on the other hand, cues your brain to put the fork down.
26
When you’re not getting enough sleep, leptin levels plummet, signaling your brain to eat more food.
27
Put the two together, and it’s no wonder sleep deprivation leads to overeating and extra pounds.
28
In fact, sleep-deprived participants in one study, ate an average of 300 calories more per day.
29
Plus, when you’re sleep deficient, your brain's reward center lights up, looking for something that feels good.
30
So while you might be able to avoid food cravings when you’re well rested, your sleep deprived brain may have trouble saying no to a second slice of cake.
31
3. It's like being drunk Lack of sleep dulls activity in the brain’s frontal lobe, which involves motor function and problem solving.
32
Your reaction time is slower and you don't have the mental clarity to make the best decisions.
33
So it’s a little like being drunk.
34
A National Sleep Foundation survey has revealed that 60 percent of adult drivers say they have driven a vehicle while feeling drowsy.
35
And more than one third have actually fallen asleep at the wheel.
36
Unfortunately, many of these situations end in tragedy.
37
It's estimated that sleep deprived driving is responsible for a full 20 percent of all vehicle crashes.
38
That would mean it causes approximately 1 million crashes each year in the U.S., eight thousand of which are fatal.
39
So think twice before hopping behind the wheel, when you know you didn't get enough sleep.
40
4. You might die early Reduced sleep time is a greater mortality risk than high blood pressure, heart disease and even smoking.
41
In one meta-analays they discovered that people who slept for less than six hours each night, were 12 percent more likely to die prematurely, than those who slept the recommended six to eight hours.
42
The team analysed 16 studies involving a total of 1.3 million people before reaching their conclusions.
43
While you’re asleep, your body takes care of all of the regenerative jobs needed to keep it healthy.
44
Without sleep, this regeneration process isn't completed.
45
What suffers is your immune system.
46
If you're not sleeping properly there can be significant issues in terms of your body's ability to fight off infections.
47
Our immune system is designed to protect us from colds, flu, and other diseases, but when it is not functioning properly, it fails to do its job.
48
That makes you more likely to get sick and stay sick, or have a slow healing time for any injuries you may have.
49
I hope this gave you some insight on just how much sleep can affect our well being.
50
If you want to know how to prevent all these deficiencies, you should check out my book summary of "Sleep Smarter", which will give you all the necessary tools to improve your sleep.

Perché praticare il parlato con questo video?

Il video "Cosa succede quando non dormiamo a sufficienza - Effetti spaventosi della privazione del sonno" è un'ottima risorsa per la pratica di conversazione in inglese. Attraverso le sue informazioni pertinenti e attuali, gli studenti possono immergersi in un argomento che li coinvolge, facilitando così il processo di apprendimento. Praticare il parlato con questo video permette di riflettere sui dilemmi quotidiani connessi al sonno e al suo impatto sulla salute, rendendo la shadow speech un'esperienza più autentica. Inoltre, utilizzare frasi e vocaboli direttamente dalla narrazione aiuta a migliorare sia la fluenza che la pronuncia.

Grammatica & Espressioni nel contesto

  • “Lack of sleep hurts…” - Questo utilizzo della forma verbale "hurts" mostra come le conseguenze della mancanza di sonno siano presentate in modo diretto e chiaro. Gli studenti dovrebbero notare l'importanza della forma attiva in questo contesto.
  • “Studies show that…” - Questa espressione è utile per introdurre dati e informazioni. Rappresenta un modo comune di citare ricerche nel linguaggio accademico e tecnico, e può arricchire il vocabolario degli studenti durante la pratica di conversazione in inglese.
  • “It's like being drunk.” - Questa comparazione rende il concetto più accessibile e memorabile. Usare similitudini può aiutare gli studenti a esprimere idee complesse in modo più efficace.
  • “If you're not sleeping properly…” - L'uso di condizioni ipotetiche stimola una discussione su cause ed effetti, un aspetto chiave nella grammatica inglese che vale la pena praticare in contesti conversazionali.

Trappole comuni nella pronuncia

Ci sono alcune parole e frasi nel video che potrebbero risultare difficili da pronunciare per gli studenti. Ad esempio, termini come “deprivation” e “contributing” presentano suoni che possono creare confusione. È fondamentale prestare attenzione alla pronuncia di vocali e consonanti in queste parole per evitare fraintendimenti. Praticare con shadowing in inglese consente di affinare l'articolazione e migliorare la pronuncia inglese generale. Ascoltare attentamente il narratore e ripetere le frasi in tempo reale può anche aiutare a migliorare la fluidità e la sicurezza nel parlare.

Cos'è la tecnica dello Shadowing?

Shadowing è una tecnica di apprendimento delle lingue supportata da studi scientifici, originariamente sviluppata per la formazione dei traduttori professionisti e resa popolare dal poliglotta Dr. Alexander Arguelles. Il metodo è semplice ma potente: ascolti un audio in inglese di madrelingua e lo ripeti immediatamente ad alta voce — come un'ombra che segue il parlante con un ritardo di solo 1–2 secondi. A differenza dell'ascolto passivo o degli esercizi di grammatica, lo shadowing costringe il tuo cervello e i muscoli della bocca a elaborare e riprodurre simultaneamente i modelli di discorso reale. La ricerca dimostra che migliora significativamente la precisione della pronuncia, l'intonazione, il ritmo, il discorso connesso, la comprensione dell'ascolto e la fluidità del parlato — rendendolo uno dei metodi più efficaci per la preparazione alla prova di speaking dell'IELTS e per la comunicazione reale in inglese.
