Stressed? It is shown in recent research that walking or cycling to work calms you down (traveling by bus or train is also better than driving).

Walking to work reduces stress and improves brain power, researchers say. Adults who stopped driving the car and started walking or cycling became calmer and found it easier to concentrate. A study of 18,000 Britons found that going to work by train or bus improved their well­being compared with driving.

The study, published in the journal Preventive Medicine, also found that the longer people spent walking or cycling, the happier or less stressed they were. However, stress levels and inability to concentrate worsened if they spent more time in the car.

Lead researcher Adam Martin, from the University of East Anglia's Norwich Medical School, said that despite the crowds and disruption, walking to bus stops or stations and being able to relax on the journey “cheer people up”. Two thirds drive to work, 18 percent use public transport, 11 percent walk and 3 percent cycle.

A research earlier this year found that commuters (乘公共车辆往返者) had small but statistically significant lower scores on all measures of well­being. The worst effects were witnessed in those whose journeys last between 61 and 90 minutes. But when commuting time reaches three hours or more, the negative effects disappear, the report said.

“The effects of commuting on personal well­being are the greatest for anxiety and happiness, suggesting that commuting affects day­to­day emotions more than overall evaluations of satisfaction with life or the sense that daily activities are worthwhile，” the report stated.

Dr Daniel Newman, from Cardiff University's Sustainable Places Research Institute, said, “This report says that many of us, who spend mornings and evenings sitting in traffic jam, already know: commuting can be a chore.”
