The air in your office is probably damaging your health
You might think it's your colleagues or the pressures of work that's getting you down at the office, but new research suggests it could well be the air you're breathing instead. Scientists in the US have found that the concentration of carbon dioxide inside the confined spaces we use every day could be high enough to damage our health.
Of course, it's well established that high levels of CO2 are dangerous, not just for human beings but for the planet as a whole, but the new research raises questions about carbon dioxide concentrations that were previously considered harmless.
The researchers gathered together 24 volunteers and tested their performance in three different simulated office environments. The key metric here is parts-per-million (ppm) of CO2: 5,000 ppm is currently considered the safe limit for an 8-hour workday, while 90,000 ppm will kill you within f5 minutes.
研究者们找来了24名志愿者,把他们分在三个不同的模拟环境下测试他们的反应.这里有个关键的标准,那就是对于8小时工作而言,5000 ppm的二氧化碳目前被人认是安全标准,如果是90000 ppm,那么你5分钟内就会死.
The team experimented with three different levels over the course of a standard 9-to-5 routine: 550 ppm (similar to outdoor levels), 945 ppm (what you would expect in most offices) and 1,400 ppm (denser but still plausible for many offices).
