Complaints about traffic congestion are nothing new.
In fact, traffic congestion has been blamed for a quarter of the deaths worldwide since the first car crash in 1879.
But in recent years, a growing body of evidence suggests that traffic congestion may actually be making people sicker.
In a study published in the journal BMJ Open, researchers from Oxford University and the University of Bristol looked at data from nearly 40,000 people who had been involved in at least 1,000 traffic accidents between 2001 and 2013.
They looked at how the people’s symptoms were related to how they felt about their environment.
The researchers found that while there were many different factors at play in the study, they found that the people who were more likely to experience traffic congestion were more stressed.
In particular, the stress level that people felt after an accident was linked to their perception of the severity of the accident and how much stress they felt.
The stress levels associated with congestion in traffic were not as high as people think, the researchers found.
They were, however, more common in those who were in a hurry, had poor self-control, were distracted, or were older than 30.
What the research doesn’t prove, however.
The stress levels were also higher in those in poorer households.
The researchers say that the reason for this might be that poor people who live in more congested areas are more likely than wealthier people to be stressed by the congestion.
This suggests that poor households, particularly those with lower incomes, are less likely to be able to access the services they need.
This, in turn, makes them less likely than wealthy people to seek help for their health problems.
According to the researchers, it’s also possible that the stress levels caused by traffic congestion could affect the way people cope with their illnesses.
If people feel stressed, they may stop taking medication, which can make them feel worse.
In turn, that can worsen the symptoms.
The research also found that some people were more susceptible to the effect of congestion if they had an underlying medical condition that was also linked to stress.
These people tended to have higher levels of anxiety and depression.
If you’re a driver, you may also want to take a look at the research and think about ways you can improve the quality of your life.
