Overweight and obese workers are more likely to be physically active at work if there is a risk of incurring a financial penalty if they are too sedentary, a study suggests. 

Researchers from the University of Pennsylvania in Pennsylvania, USA undertook a study to assess the efficacy of three strategies to increase physical activity among overweight and obese workers by providing a financial incentive. 

They said most workplace health interventions had tended to better engage workers with higher baseline physical activity levels rather than more sedentary workers, including those who are obese or overweight.  

Noise is an unwanted or damaging sound that may damage your hearing and cause other health effects such as stress, hypersensitivity to noise, increased blood pressure and increased heart rate. It can also interfere with communication at work, which could lead to accidents.

WorkSafe ACT is investigating how a 25-year-old man fell three metres from scaffolding at a worksite in Canberra's north.
An Emergency Services Agency spokesperson said the man was taken to the Canberra Hospital after a "difficult extraction" with injuries to his lower back and pelvis.
He has since been discharged from hospital.
The fall happened about 10:30am on Monday at a worksite on the corner of Gozzard and Ernest Cavanagh streets in Gungahlin.
In a statement, Greg Jones from Access Canberra said WorkSafe inspectors conducted an audit of the entire site after the accident, issuing six improvement notices for matters including clear access, configuration of scaffolding and handrail systems.
A notice was also issued preventing work in the area of the incident while WorkSafe conducts its investigation.
"While I am pleased to report that the worker has been able to leave hospital, I was saddened, and disappointed, to learn that a Canberra worker had suffered injuries during the course of his employment," Mr Jones said.
"Tasks involving working at heights is one of the most dangerous activities on construction sites.
"I reiterate the importance of being diligent in all workplaces, especially in high risk workplaces such as construction sites."
