Workplace wellness and health promotion
The majority of working-aged people spend most of their waking hours at work. IWH research examines the impact of the work environment on worker health and wellbeing, as well as the effectiveness of workplace health and wellness promotion initiatives on workers’ physical activity and other health behaviours.

Standing too long at work carries twice the risk of heart disease as sitting too long
There has been a lot of interest in recent years in the health risks of prolonged sitting. But a study by IWH and the Institute for Clinical Evaluative Sciences suggests you might spare a thought for people in jobs that mostly involve standing (e.g. cooks, tellers, cashiers).

No, a standing desk isn't as unhealthy as smoking
A headline today has proclaimed that standing at work is “as unhealthy as a cigarette a day," citing a new study published in the American Journal of Epidemiology. Illustrated with a picture of a woman bent over her standing desk clutching at her back, we’re instructed to “sit back down." But a closer look at the research in question reveals very little to do with standing desks. In fact, the study did not look at standing desks at all, writes Suzi Gage.

Research Highlights
Prolonged standing on the job associated with higher risk of heart disease than prolonged sitting
Workers who predominantly stand on the job are at greater risk of heart disease than workers who predominantly sit. Workplace prevention efforts should target excessive standing, as well as excessive sitting, to protect the cardiovascular health of workers.

If you stand for too long at work, you could double your risk of this disease
Odds are, you already know about the scary things that sitting can do to your health. But we have some bad news: Your standing desk may be doing more harm than good, too, writes Brooke Nelson.

Standing too much at work can double your risk of heart disease
People who primarily stand on the job are twice as likely to develop heart disease as people who primarily sit. This was the case even after taking into account a wide range of factors, including personal factors, health and the type of work being performed, writes Dr. Peter Smith in The Conversation.

Standing all day is twice as bad as sitting for your heart
On the circle of health hype, what was bad becomes good, then it becomes overrated, then it becomes bad again. That’s what happened to barefoot running and multivitamins, and it’s where the purported dangers of “too much sitting” seem to be headed. But the truth is probably somewhere in the middle rather than on the peaks or in the valleys. With that in mind, it’s worth looking at an interesting study just published in the American Journal of Epidemiology that finds jobs that require a lot of standing to be much worse for your health than jobs that require mostly sitting, writes Alex Hutchinson.

Too much standing is bad, study finds — it's time to move
People who stand for long periods at work may have another reason to join their seated colleagues in moving more. "There's a good body of research evidence that shows standing a lot is actually bad for your health," said Peter Smith, a senior scientist at the Institute for Work & Health.

Risk of heat- or cold-related illnesses across a broad population of Ontario workers
It's long been known that extreme temperatures can pose health hazards, from heat stress disorders to hypothermia and frost-bite. An IWH study found that a strong relationship exists between outdoor temperature and illness among the working population. And, as this study shows, it's not just in extreme temperatures that workers are at risk.
