Sitting for long periods 'is bad for your health'
【久坐有害健康】{:soso_e113:}
Sitting for long periods increases the risk of diabetes, heart disease and death, researchers suggest.
The scientists from Leicester and Loughborough Universities【google：英国莱斯特大学和拉夫堡大学】 say harm is done even if people alsoexercise.
The study, published in Diabetologia,analysed 18 existing studies involving almost 800,000 people.
Diabetes UK said anyone who spent a lot of time sitting or lying down would "obviously benefit" from moving more.【长时间坐卧的人会从运动中明显受益】
The researchers say the opportunities for sedentary【久坐不动】 behavior in modern society such aswatching TV, sitting in a car or using a computer are "ubiquitous"【普及，极为普遍】.
Of course, inmodern society many people head to the gym 【体育馆】for a burst of exercise to redress the balance.
But the research team, led by Dr Emma Wilmot from the Diabetes Group at the University of Leicester, says while going to the gym or pool after work is better than heading straight for the sofa, spending along time sitting down remains bad for you.
Healthy life style?【健康的生活方式？】
Each of the studies they assessed used different measures - for example more or less than 14 hours a week watchingTV, or self-reported sitting time of less than three hours a day to more thaneight.
The researchers say thismeans it is not possible to give an absolute limit for how much sedentary time is bad for you.
But Dr Emma Wilmot, who led the study,said it was clear that those who sat the most had a higher risk of diabetes, heart disease and death【糖尿病，心脏疾病和死亡……一个比一个恐怖，还好只是理论统计可能性，唉】 than those who sat the least.
We can have standing meetings, we can walk during the lunch break, and we can look to reduce TV viewing in the evenings by seeking out less sedentary behaviours”

She said: "If a worker sits at their desk all day then goes to the gym, while their colleague headshome to watch TV, then the gym-goer will have better health outcomes.
"But there is still a health risk because of the amount ofsitting they do.
"Comparatively, the risk for awaiter who is on their feet all day is going to be a lot lower."
She added: "People convince themselves they are living a healthy lifestyle, doing their 30 minutesof exercise a day.
"But they need to think about the other 23.5hours."
'Easy change'【轻松转变】
The strongest associations in the analysis were between prolonged sitting and diabetes.
There is evidence that being sedentary negatively affects glucose levels【血糖水平】 and increases insulin
resistance【胰岛素抵抗】 - but scientists do not yet know how.
Dr Wilmot said the study's message could help those at high risk of diabetes, such as obese people or those of South Asian ethnic origin, because it was an easy lifestyle change to make.
Prof Stuart Biddle, of LoughboroughUniversity, who also worked on the study, said: "There are many ways we can reduce our sitting time, such as breaking up long periods at the computerat work by placing our laptop on a filing cabinet【把笔记本放在文件柜上。意思大概是要大家伙儿站立了……】.
"We can have standing meetings, we can walk during the lunch break, and we can look to reduce TV viewing in the evenings by seeking out less sedentary behaviours."
Dr Matthew Hobbs, head of research at Diabetes UK, said people should not be discouraged from exercising.
He added: "What is clear is that anyone whospends lots of time sitting or lying down would benefit from replacing some ofthat time by standing or walking.
"Aside from any direct effect reducing the amount oftime you spend sitting down may have, getting more physical activity is a great way of helping maintain a healthy weight, which is the best way of minimising your risk of Type 2 diabetes.【2型糖尿病，啥东东？？】"
