Summary

This trial will test if changing the time people travel to work can reduce their exposure to traffic pollution and improve their health. It focuses on 65 people who will alter their travel times to avoid times when pollution is highest.

Who is the study for?
This trial is for adults over 18 who commute more than 20 minutes to work in Hartford County, including driving during rush hour. Participants must be able to complete surveys in English and work outside the home on consecutive days. Smokers, those exposed to secondhand smoke, with chronic lung diseases like COPD or asthma (with recent exacerbations), on hypertension medications, or pregnant individuals cannot join.
What is being tested?
The study examines how changing commuting times and methods affects exposure to traffic-related air pollutants and health. Participants will commute by car during peak and off-peak hours on different days to measure changes in pollutant exposure levels.
What are the potential side effects?
There are no direct side effects from participating in this study since it involves modifying commuting habits rather than testing a medical intervention. However, there may be indirect effects related to stress or inconvenience.

Other Research
The most common treatments for pollution exposure involve behavioral changes such as altering commute times to avoid peak traffic periods and choosing alternative modes of transportation like cycling or walking on less trafficked routes. These strategies aim to reduce personal exposure to pollutants like particulate matter (PM2.5, PM10), black carbon (BC), and carbon monoxide (CO). By minimizing exposure to these harmful pollutants, individuals can potentially reduce the risk of respiratory and cardiovascular issues, which are exacerbated by high levels of TRAPs. This is particularly important for pollution exposure patients as it directly impacts their overall health and quality of life.
