In today's fast-paced world, traffic jams are not just a nuisance; they can have a significant impact on mental health. Recent research, published in the Journal of Transport & Health, has shed light on the serious consequences of prolonged daily commutes, extending beyond mere inconvenience. The study reveals that lengthy commutes can lead to mental health issues, potentially causing depression.

The research highlights various ways in which extended commute times negatively affect health. Long commutes contribute to a decrease in physical activity, increased alcohol consumption, and poor sleep. The limited time available for personal activities due to a busy commute schedule is a major factor in these health implications.

While limited research exists on the health impacts of long commutes, a recent study in South Korea provides valuable insights. South Korea, known for its long average commute times and high depression rates among OECD nations, was the focus of this study. Analyzing data from 23,415 individuals aged 20-59 using the Fifth Korean Working Condition Survey (2017), the study assessed participants' mental health using the WHO well-being index, considering factors such as sex, age, education, income, and employment details.

Led by Dr. Lee Dong-wook of Inha University Hospital, South Korea, the research revealed significant findings. Individuals with over an hour of daily commute were found to be 1.16 times more prone to depression compared to those with commutes under 30 minutes. The average commute time was 47 minutes daily, translating to nearly four hours weekly for a five-day work schedule. This amount of commuting can lead to both physical and psychological stress, limiting stress-relief activities and healthy living practices, such as exercise. While the study did not establish a direct cause-effect relationship, it observed a correlation between long commutes and poorer mental health, particularly in unmarried men working over 52 hours weekly without children.

The study also found a stronger connection between lengthy commutes and depression symptoms in women, particularly among those with lower incomes, shift work schedules, and parental responsibilities. The negative impact of long commuting times on mental health was more pronounced among lower-income workers.
