Now, let’s examine sample essays for different band scores, starting with a high-scoring response.

Band 8-9 Sample Essay

In recent years, the pervasive use of mobile devices has become an integral part of our daily lives, extending well into our bedtime routines. I strongly agree with the statement that this trend is significantly deteriorating sleep quality among young adults, and this essay will explore the reasons behind this phenomenon and its consequences.

Firstly, the blue light emitted by mobile screens interferes with the body’s natural circadian rhythm. This type of light suppresses the production of melatonin, a hormone crucial for regulating sleep patterns. Consequently, young adults who engage with their devices before bed often find it difficult to fall asleep promptly and may experience less restorative sleep overall. A study published in the Journal of Clinical Sleep Medicine found that individuals using light-emitting devices before bed took longer to fall asleep and had reduced REM sleep compared to those who did not.

Moreover, the constant connectivity provided by mobile devices creates a state of mental arousal that is counterproductive to sleep. Social media notifications, instant messages, and the temptation to check emails can keep the mind active and alert, making it challenging to wind down and prepare for sleep. This heightened state of alertness can lead to racing thoughts and anxiety, further exacerbating sleep disturbances.

Additionally, the content consumed on mobile devices can be stimulating or emotionally charged, which is not conducive to relaxation. Whether it’s watching an exciting video, engaging in online debates, or reading distressing news, these activities can elevate stress levels and make it difficult for young adults to transition into a calm state necessary for quality sleep.

However, it is important to note that while the impact of mobile devices on sleep quality is significant, it is not irreversible. Implementing digital curfews, using blue light filters, and practicing good sleep hygiene can mitigate these negative effects. The importance of healthy lifestyle choices cannot be overstated in this context, as they play a crucial role in maintaining overall well-being, including sleep quality.

In conclusion, the widespread use of mobile devices before bedtime is indeed causing a substantial decline in sleep quality among young adults. The combination of blue light exposure, mental stimulation, and potentially stressful content creates a perfect storm for sleep disruption. As society becomes increasingly reliant on technology, it is crucial to find a balance and establish healthy boundaries with our devices to ensure adequate rest and overall well-being.

Band 6-7 Sample Essay

The use of mobile devices before going to sleep has become very common among young people today. I agree that this habit is causing problems with sleep quality for many young adults, and I will explain why in this essay.

One main reason why mobile devices affect sleep is because of the bright light from the screens. This light can make it harder for people to feel sleepy at night. When we look at bright screens, our brains think it’s still daytime and don’t produce enough of the sleep hormone melatonin. This means it takes longer to fall asleep and the sleep might not be as deep.

Another problem is that mobile devices keep our minds too active before bed. When we use social media or play games, our brains stay excited and alert. This makes it difficult to relax and prepare for sleep. Many young adults might find themselves thinking about things they saw online instead of calming down for the night.

Also, using mobile devices can be addictive. Some people find it hard to stop scrolling through social media or watching videos, even when they know they should be sleeping. This can lead to staying up much later than intended, reducing the total hours of sleep.

However, it’s important to note that not all use of mobile devices is bad. Some apps can help with relaxation or sleep tracking, which could be beneficial if used correctly. The key is to find a balance and use these devices responsibly.

In conclusion, I strongly agree that mobile devices are negatively impacting sleep quality for many young adults. The combination of bright screens, mental stimulation, and addictive nature of these devices can significantly disrupt healthy sleep patterns. It’s important for young people to be aware of these effects and try to limit their device use before bedtime.

Band 5-6 Sample Essay

Nowadays, many young people use their mobile phones before they sleep. I think this is bad for their sleep quality. There are some reasons for this.

First, mobile phones have bright screens. When people look at bright screens at night, it can make it hard to sleep. The light from the phone makes the brain think it is still daytime. This means people might not feel sleepy when they should.

Second, mobile phones can be exciting. People might play games or chat with friends. This keeps their mind active when it should be relaxing. If the mind is too active, it’s hard to fall asleep quickly.

Also, some people spend too much time on their phones. They might plan to use it for a short time but end up using it for hours. This means they go to sleep very late and don’t get enough sleep.

But not everything about phones is bad for sleep. Some phone apps can help people relax or play calm music. These might be good for sleep if used the right way.

In conclusion, I agree that mobile phones can make sleep worse for young adults. The bright screens and exciting content can make it hard to sleep well. Young people should try to use their phones less before bedtime to get better sleep.
