People nowadays often spend a lot of time sitting, and this can lead to various health problems. What are the reasons for this? What problems does this cause?

Many people today spend most of their day sitting down, whether at work, on a motorbike, or in front of a screen at home. This essay will look at the main reasons why people are sitting more, and the health problems that this can cause.如今许多人一天中的大部分时间都是坐着度过的,无论是在工作时、骑摩托车时,还是在家看屏幕时。本文将探讨人们久坐增多的主要原因,以及由此带来的健康问题。

One reason is that many jobs, especially office jobs, now require workers to sit at a computer for the whole day instead of moving around. Technology has also made life easier but more inactive: people can now work, shop, and order food without leaving their chair. For example, apps like GrabFood and ShopeeFood let office workers order lunch to their desk, so they do not even need to walk to a nearby restaurant. Motorbike commuting also means people sit for long periods instead of walking to school or work like before.原因之一是,如今许多工作,尤其是办公室工作,要求员工整天坐在电脑前,而不是四处走动。科技也让生活变得更轻松,但也更缺乏活动:人们现在不用离开座位就能工作、购物和点餐。例如,GrabFood和ShopeeFood这类应用让上班族可以把午餐直接叫到工位,连走去附近餐厅的这段路都省了。骑摩托车通勤也意味着人们长时间坐着,而不像以前那样走路去上学或上班。

This lack of movement causes several serious health problems. Sitting for long hours can lead to weight gain, back pain, and a higher risk of diseases such as diabetes and heart disease. It can also lower people's energy levels and make them less productive at work or school. Because these problems develop slowly, many people do not realise the damage to their health until they go for a check-up and the doctor tells them the results, by which point the problem may already be serious.缺乏运动会引发一些严重的健康问题。长时间久坐可能导致体重增加、背痛,以及患糖尿病和心脏病等疾病的风险升高。它还会降低人的精力水平,使人在工作或学习时效率下降。由于这些问题发展得很缓慢,很多人直到去体检、医生告知结果时才意识到健康受损,而这时问题可能已经比较严重了。

In conclusion, desk jobs, motorbike commuting and delivery apps are the main reasons why people today sit so much. This sedentary lifestyle can seriously damage people's physical health, and it also creates problems for the wider healthcare system if not treated early.总之,办公室工作、骑摩托车通勤和外卖应用是如今人们久坐不动的主要原因。这种久坐的生活方式会严重损害人们的身体健康,如果不及早处理,也会给整个医疗系统带来负担。

In Vietnamese cities, daily life for many office workers and students now revolves around sitting: at a desk during the day, on a motorbike in traffic, and then in front of a screen at home in the evening. This essay will examine the main causes of this increasingly sedentary lifestyle and the health problems it can create.在越南的城市里,许多上班族和学生的日常生活如今都围绕着“坐”展开:白天坐在办公桌前,通勤时坐在摩托车上,晚上回家又坐在屏幕前。本文将探讨这种日益久坐的生活方式的主要成因,以及它可能带来的健康问题。

A major cause is the changing nature of work and daily habits. Many jobs that once involved moving between departments or visiting clients can now be done entirely through email and messaging apps, keeping employees seated for hours. Convenience technology adds to the problem: food delivery apps such as GrabFood and ShopeeFood mean that even the short walk to a nearby restaurant for lunch is no longer necessary. A friend of mine who works in marketing told me that after a year of ordering lunch to her desk almost every day, her company health check showed early signs of high cholesterol, which her doctor linked directly to her lack of movement.一个主要原因是工作性质和日常习惯的改变。许多以前需要在部门之间来回走动或拜访客户的工作,如今完全可以通过邮件和聊天软件完成,员工因此一坐就是几个小时。便利的科技进一步加剧了这个问题:GrabFood和ShopeeFood之类的外卖应用意味着,就连去附近餐厅吃午饭这一小段路都不再需要走了。我一位做市场营销的朋友告诉我,她几乎每天都把午餐叫到工位上,一年后公司体检显示她的胆固醇偏高,医生直接将此归因于她缺乏运动。

This widespread inactivity leads to a range of health problems that go beyond the individual. Physically, prolonged sitting raises the risk of conditions such as heart disease, diabetes, and back or neck pain, which are becoming increasingly common even among people in their twenties and thirties. In addition to these physical effects, a largely sedentary population can also place growing pressure on the public healthcare system, as hospitals treat more young adults for conditions once mainly associated with old age. Because these problems tend to develop gradually, many people fail to take action until the damage has already become serious.这种普遍的缺乏活动会引发一系列不仅限于个人层面的健康问题。从身体上看,长期久坐会提高患心脏病、糖尿病以及背部或颈部疼痛的风险,而这些问题如今在二三十岁的年轻人中也越来越常见。除了这些直接的身体影响之外,一个普遍久坐的群体也会给公共医疗系统带来越来越大的压力,因为医院要治疗越来越多原本主要与老年人相关的疾病的年轻患者。由于这些问题往往是逐渐发展的,许多人直到损害已经变得严重时才开始采取行动。

In conclusion, desk-based jobs, motorbike commuting, and the convenience of delivery apps are the main reasons behind today's sedentary lifestyles. This behaviour, in turn, contributes to a range of chronic health problems and adds a growing burden to the healthcare system if it is not addressed early.总之,办公室工作、骑摩托车通勤以及外卖应用的便利性,是当今人们久坐生活方式背后的主要原因。这种行为进而会导致一系列慢性健康问题,如果不及早解决,还会给医疗系统带来日益沉重的负担。

Modern life, especially for office workers and students in Vietnamese cities, increasingly revolves around sitting: at a desk from nine to six, then on a motorbike in traffic, then in front of a screen at home. This essay will examine the principal causes of this sedentary existence and the significant health problems it subsequently causes.现代生活，尤其是对越南城市里的上班族和学生而言，越来越离不开「坐」：早上九点到晚上六点坐在办公桌前，下班路上坐在摩托车上堵在车流里，回到家又坐在屏幕前。本文将探讨这种久坐生活方式的主要成因，以及随之而来的重大健康问题。

Technological change and shifting daily habits are major drivers of this trend. Work that once required moving between departments or physically visiting suppliers can now be handled entirely through email and messaging apps, while motorbikes, though far more active than sitting in a car, still involve long periods of stillness and have replaced the walking that once got people to markets, schools and offices. Food delivery apps such as GrabFood and ShopeeFood compound the problem, removing even the short walk to a nearby quán ăn. My own experience as a marketing executive in Ho Chi Minh City illustrates this clearly: after two years of ordering lunch to my desk almost daily and rarely leaving my chair between meetings, an annual company health check revealed early-stage fatty liver and elevated cholesterol, which the doctor attributed directly to prolonged sitting and a poor diet. That result prompted me to start running along the Saigon River most mornings before work, a habit that has noticeably improved both my energy levels and my check-up results.科技变革和日常习惯的转变是这一趋势的主要推动力。以前需要在各部门间走动，或亲自拜访供应商才能完成的工作，如今完全可以通过邮件和聊天软件处理；摩托车虽然比坐在汽车里活动量大一些，但骑行本身仍需长时间保持静止的姿势，而且它已经取代了人们以前步行去市场、学校和办公室的习惯。外卖软件如GrabFood和ShopeeFood更是加剧了这一问题，就连走到附近小吃摊的那一小段路也被省去了。我自己作为一名在胡志明市工作的市场营销主管的经历就很能说明这一点：连续两年几乎每天都叫外卖送到工位，会议间隙也很少离开座位，一次年度体检结果显示我出现了早期脂肪肝和血脂升高，医生直接将其归因于长期久坐和饮食不健康。那次结果促使我开始在每天上班前沿着西贡河晨跑，这一习惯明显改善了我的精力状态和体检结果。

Such widespread inactivity leads to a range of serious health complications that extend well beyond the individual. Physically, prolonged sitting significantly raises the risk of chronic conditions such as cardiovascular disease, type 2 diabetes and musculoskeletal problems, particularly lower back and neck pain, which are increasingly common complaints among young office workers. Beyond these direct physical effects, a largely sedentary workforce can also lead to reduced productivity and a growing burden on the public healthcare system, as hospitals treat increasing numbers of adults in their thirties and forties for conditions once associated mainly with old age. Because the onset of these problems is usually gradual rather than sudden, many people fail to notice the damage until it has already become serious, making early intervention difficult and long-term treatment costly.如此普遍的缺乏运动会引发一系列严重的健康问题，其影响远不止于个人层面。从身体层面看，长期久坐会显著提高罹患心血管疾病、2型糖尿病以及肌肉骨骼问题（尤其是腰颈疼痛）的风险，而这类症状如今在年轻上班族中已越来越常见。除了这些直接的身体影响外，久坐的劳动力还可能导致生产力下降，并给公共医疗系统带来日益沉重的负担，因为医院里需要治疗三四十岁成年人患上过去多见于老年人的疾病的病例正在不断增加。由于这些问题的出现往往是渐进而非突然的，许多人直到病情已经比较严重时才察觉，这使得早期干预变得困难，长期治疗的成本也随之升高。

In conclusion, the prevalence of prolonged sitting among today's workers and students is largely a consequence of desk-based jobs, motorbike commuting and the convenience of delivery apps. This behaviour, in turn, exacts a heavy toll, contributing to a range of chronic diseases and placing a substantial strain on both individuals and the healthcare system.总之，如今上班族和学生普遍久坐，在很大程度上是办公桌工作、摩托车通勤以及外卖软件便利性共同作用的结果。而这种行为反过来也付出了沉重的代价，导致一系列慢性疾病，并给个人和医疗系统都带来了巨大压力。
