本文是youressay网课代上原创essay关于睡眠的重要性的文章。睡眠，如氧气，水和食物，是我们日常生活中不可或缺的元素。不幸的是，我们很多人都忽略了它。在这个快节奏的社会中，人们承受着前所未有的压力。这导致人们没有足够的时间睡觉。睡眠剥夺会导致许多问题，例如影响人们的健康，认知能力，最重要的是安全性。统计数据显示，世界上超过61％的人处于睡眠不足状态，约67％的人认为睡眠剥夺对他们的幸福和健康有明显的影响。在美国，69.7％的男性和61.8％的女性被归类为睡眠不足者。 （Khan Awan等，2018）。睡眠非常重要，睡眠不足对学生产生负面影响，如影响健康，导致注意力下降，伤害精神状态。

Sleep, like oxygen, water, and food, is an indispensable element of our daily life. Unfortunately, it is neglected by many of us. In this fast-paced society, people are under more stress than ever before. This leads to people not having enough time to sleep. Sleeping deprivation can lead to many problems, such as affecting people's health, cognitive ability, and most importantly, safety. The statistics shows that more than 61% of the people in the world are in lack of sleep and about 67% of them think that sleep deprivation has obvious effect on their happiness and health. In America,   69.7% of the males and 61.8% of the females were classified as poor sleepers. (Khan Awan et al., 2018). Sleep is very important, and a lack of sleep has negative effects on students like impacting their health, leading to a decline in concentration, and harming their mental state.

首先，睡眠剥夺会影响学生的健康和安全。它可以引起许多疾病，如头痛。根据Ranasinghe，Gayathri和Priya（2018）的研究，100多名大学生在问卷调查中写道，睡眠剥夺让他们头疼。睡眠剥夺还会导致血压升高和与炎症相关的更高水平的化学物质，这两者都可能是心脏病的诱因（Cherney，K。，＆Watson，S。）。此外，睡眠剥夺对免疫系统有负面影响。当我们睡觉时，我们的免疫系统会产生像细胞因子这样的保护性抗感染物质。这些物质用于对抗外来入侵者，如细菌和病毒。它们为我们的免疫系统提供更多能量来保护我们的身体免受疾病的侵害（Cherney，K。，＆Watson，S。）。睡眠剥夺会阻止免疫系统增强其力量。如果我们睡眠不足，我们的身体可能无法抵御入侵者，也可能需要更长的时间才能从疾病中恢复过来（Williams，2013）。总之，我们应该及早休息，以防止潜在的疾病。失眠也会损害我们专注或专注于手头任务的能力。例如，睡眠不足时更容易卷入车祸。如果我们在街对面时感到困倦，我们就不能马上停下来，这更容易发生车祸（Williams，2013）。昏昏欲睡也会增加受伤的机会（Cherney，K。，＆Watson，S。）。睡眠剥夺会导致健忘和无法集中注意力。而这些症状导致表现下降（Davis，2018）。这表明我们应该为了集中能力而重视睡眠。

First of all, sleep deprivation can affect students’ health and safety. It can cause many diseases, such as headache. According to Ranasinghe, Gayathri and Priya (2018), more than 100 college students wrote in questionnaires that sleep deprivation made their heads ache. Sleeping deprivation also leads to increased blood pressure and higher levels of chemicals linked to inflammation, both of which could be the trigger of heart disease (Cherney, K., & Watson, S.). Besides, sleeping deprivation has negative effect on immune system. While we sleep, our immune system produces protective, infection-fighting substances like cytokines. These substances are used to combat foreign invaders such as bacteria and viruses. They give our immune system more energy to defend our body against illness (Cherney, K., & Watson, S.). Sleep deprivation prevents the immune system from building up its forces. If we don’t get enough sleep, our body may not be able to fend off invaders, and it may also take us longer to recover from illness (Williams, 2013). In conclusion, we should have early rest to prevent potential illness. Missing sleep also harms our ability to concentrate or focus on the task at hand. For example, it is more likely to get involved in car accidents when having inadequate sleep. If we feel sleepy while walking across the street, we can't stop immediately, which make a car accident more likely (Williams, 2013). Being drowsy can also increase the chance of injuries (Cherney, K., & Watson, S.). Sleep deprivation can lead to forgetfulness and inability to concentrate. And these symptoms result in decreased performance (Davis, 2018). This indicates that we should value sleep for the sake of concentration ability.

充足的睡眠对学生的认知能力非常重要。它在决策和判断中发挥着重要作用。研究表明，睡眠不足的人不能很好地考虑问题的不同方面。因此，他们经常做出错误的决定。这将极大地影响测试和家庭作业的结果（Davis，2018）。睡眠不足会对短期和长期记忆产生负面影响，这也会影响我们的判断（Cherney，K。，＆Watson，S。）。更重要的是，充足的睡眠可以减少焦虑。长期睡眠不足会导致焦虑，缓解这种情况的唯一方法就是弥补睡眠（Davis，2018）。足够的睡眠显然是影响认知能力的关键因素之一。

Adequate sleep is very important for students’ cognitive ability. It plays an important role in decision-making and judgment. Studies have shown that people who are not getting enough sleep can't consider different aspects of the issue very well. Therefore, they often make the wrong decision. This will greatly affect the results of testing and homework (Davis, 2018). A lack of sleep can negatively impact both short-term and long-term memory, which also affects our judgment (Cherney, K., & Watson, S.). What’s more, adequate sleep can reduce anxiety. Long-term lack of sleep can cause anxiety, and the only way to relieve this situation is making up for it (Davis, 2018). Enough sleep is clearly one of the key factors affecting cognitive ability.

据我所知，睡眠剥夺对学生的健康和安全有负面影响，因此充足的睡眠非常重要。由于缺乏睡眠是一个值得关注的问题，因此使用医疗解决方案（如治疗和药物）来减少睡眠不足非常重要。因此，我建议有睡眠问题的学生向医生或睡眠治疗师寻求帮助，他们可以提供专业的解决方案。建议我们每天睡7到9个小时。如果我们不满足要求，我们最好检查一下我们的睡眠模式并找出调整方法。最糟糕的事情是继续忽视这个问题。

From what I have learned, sleep deprivation has negative effect on students’ health and safety, so adequate sleep is very important. Since a lack of sleep is such a concern, it’s important to use medical solutions, like therapy and medication to reduce sleep deprivation. Therefore, I suggest that students with sleeping problems ask help from doctors or sleep therapists, who can offer professional solutions. It is recommended that we have 7 to 9 hours of sleep each day. If we don’t meet the requirement, we had better check our sleeping pattern and figure out the way to adjust it. The worst thing to do is continuing to neglect this problem.
