Women stay relatively calmer and cooler than men when stuck behind the wheel in a traffic jam, a new study has revealed.
The research by sat-nav firm TomTom showed that a man's stress levels rise seven times higher than a woman's while stuck in heavy traffic.
The psychologists conducted tests on volunteers by measuring levels of stress chemicals in their saliva while sitting in congested traffic.
Many women have tactics such as singing to the radio to relieve pressure, with their stress levels rising only by 8.7% while waiting.
But men get frustrated, with the levels of the chemicals rising up to 60% in the same situation.
Two out of three women and half of the men denied feeling stressed after spending 20 minutes in a traffic jam, even though their readings proved otherwise.
"Fight or flight" attitude in men is one of the explanations given by the experts for the increased stress levels. This means when men are confronted with stressful situations, they tend to either confront the problem or walk away from it.
But when they are stuck in such congestions, they don't have these options and often get frustrated.
With around half of adults commuting by car everyday, people who get easily stressed out in heavy traffic jams could eventually fall to stress-related health problems.
David Moxon, a health psychologist, said that frustration could make their driving erratic and potentially dangerous.
