 在工作过程中,很多人都习惯长时间坐着办公,但是也许大家不知道,久坐已成为了影响职场人士身体健康的一大杀手。  4 b5 F1 U0 s4 L7 R
  现在的大多数年轻人每天花大量的时间坐在椅子上,缺乏必要的运动,椅子已经成为危害我们健康的主要原因。+ W$ x% H( ^5 h2 `4 K$ K

' X" U$ _# y" N5 t% l& O  You may hit the gym at lunchtime or go for a run when you get home. But such efforts will have minimal effect if you spend the rest of your time doing what you are probably doing now - sitting down.8 P& Y+ }3 T- k3 W
  你或许在午休时会去健身房,或许下班后会去跑步。但如果其余时间里你都像现在这样--久坐不动,那么你的锻炼可能收效甚微。; Z+ l' Y2 y7 `1 `/ s: D! t- _- h
6 t# O' E7 t2 U4 v
  In a glut of new research on the subject, experts are warning that we should 'beware our chair', as spending too long in it can raise the risk of high blood pressure, a sluggish metabolism and weight gain.
/ _3 B5 I6 g# l. l0 |  y  在最近大量的研究发现中,专家们警告大众要“当心你的椅子”,因为长时间“黏”在椅子上可能面临患高血压,代谢减缓和体重增加的风险。% T+ O4 s) I7 ~
% X7 O7 u9 T7 z* C, K- l/ W6 @
  With the average person sitting down for just under nine hours a day at the office, at home or in the car, even a daily workout is unlikely to offset the risks of being seated for too long.7 d4 Q, }& R: m
  一般人每天有近9小时的时间坐在办公室、家中或者汽车上,即使每天坚持锻炼,也无法抵消久坐的危害。

  U7 _; j% z; n# Q; I8 [. I" B  Sit ups: Being chair-bound for too long can raise the risk of high blood pressure, a sluggish metabolism and weight gain.# K8 j; E1 ]: r2 z& G+ C
  从椅子上站起来!久坐对身体的危害包括高血压,代谢减缓和体重增加。
' [, d% N7 {6 G. B
$ Y7 y9 Z+ d! i. f  According to Swedish scientists, quoted in the British Journal of Sports Medicine recently, prolonged sitting should carry a public health warning.
  t: v* W& h9 e  《英国运动医学杂志》最近引述瑞典科学家的观点,久坐不动已成为威胁公众健康的隐患,应当引起重视。% C; m# v7 }7 p5 e4 U  y

1 k. _" G6 J  x  So why is the humble chair being blacklisted? As the most passive activity behind lying down, being seated burns a bare minimum of calories - even eating an apple or fidgeting uses more energy than parking your bottom on a chair.5 v/ ]  Y0 A3 D; |
  但为什么这次是“老实巴交”的椅子被列入黑名单呢?作为被动性仅次于躺的活动,“坐”的状态将人体热量消耗降至最低--吃一颗苹果或“坐立不安”的扭来扭去,都比“黏”坐在椅子上消耗的热量多。) {. }0 r4 \  ^. ^( C7 W9 e- v: m
; o4 C$ f# }3 x+ N3 i
  While standing engages muscles in your back, shoulders and legs, sitting presents no positive physical challenge to the body, forcing it instead into an inactive state.
+ J8 y! {4 j8 x9 i" w& L% o8 {% D  “站立”能锻炼背部,肩部和腿部的肌肉,而“坐”不但没有对身体提出积极的体力考验,反而强制它进入懈怠状态。8 d2 D1 N8 h' c! k- H
4 F' {3 {5 E8 r  G
  It is almost inevitable, researchers say, that long-term sitters find their waistline expanding.
7 n! `& m' a$ q4 y- }  研究人员说,长期的“坐者”都不可避免的遭遇了腰围增大的现实。8 l5 C+ V2 v+ W4 n

7 Y0 E: E; F2 y: w  While the action of standing up only burns a few calories, do it enough times a day and it makes a real difference.% k$ A1 @$ Z2 Q8 Z2 Q( J) O
  虽然“站起来”一次只能消耗几卡路里的热量,但只要每天坚持做几次,就能起到明显的作用。  K- n9 K1 O) U$ x# L
9 ?$ N* P2 L' m; _1 f9 k0 v  M
  It's easy to burn 30 to 50 extra calories a day, which is enough to prevent a weight gain of 2lb to 3lb a year. Spend your time sitting down and the pounds will creep on unnoticed.
4 z7 ?  a2 n: N  每日多消耗30到50卡路里并不难,但足以防止体重每年增加2到3磅。如果大量时间都处于 “坐”的状态,肥肉就会悄悄的降临到你身上。
