Poor office air quality and lack of fresh air affects our ability to make decisions
Working in a well-ventilated 'green' office can help boost your brainpower, researchers have found.
People whose desk space is well ventilated with below average indoor pollution and carbon dioxide levels, showed more ability to think, understand, remember and learn, according to a study.
It suggests that the indoor environmental quality can have a profound impact on the decision-making and performance of workers.
Researchers at Harvard looked at the decision making abilities of 24 people, who were exposed to different indoor working conditions over six days.
The findings, published in the journal Environmental Health Perspectives, showed those with higher levels of pollutants were less able.
Participants scored an average 61 percent higher while working in buildings with low pollution levels, compared to days working in a conventional building.
They were tested on everything from basic tasks to crisis response and information seeking.

Dr Joseph Allen, director of the healthy buildings program at the Harvard Centre for Health and the Global Environment, said it was an area that had been largely ignored.
'We spend 90 per cent of our time indoors and 90 per cent of the costs of a building are (related to) the occupants, yet indoor environmental quality and its impact on health and productivity are often an afterthought,' he said.
'These results suggest even modest improvements to indoor environmental quality may have a profound impact on the decision making performance of workers.'
The findings follow British research which found having plants in offices boosts productivity by 15 per cent by making workers more physically, cognitively and emotionally involved in their jobs.
