• People exposed to high levels of residential transportation noise, including road traffic (such as cars and buses), trains and aviation, face a higher risk of serious heart-related conditions.
• The link was similar for people with healthy sleep patterns and those with unhealthy sleep patterns, defined in this study as a sleep disorder diagnosis, or sleeping more or less than 7-9 hours per night.
• The findings suggest that chronic exposure to loud transportation noise may be an environmental risk factor that increases the risk of cardiovascular disease, which regular, healthy sleep patterns may not counteract, researchers said.
