As if we needed more proof that damaging our environment has serious consequences.
Monitoring the mental health of teenagers can be one of the most challenging aspects of parenting. While many factors — such as academic stress, social dynamics, and isolation during the Covid pandemic — play a significant role in teens’ emotional well-being, recent research indicates that the air quality around them might also be a contributing factor to their mental health. A new study published in Developmental Psychology reveals a correlation between air pollution, specifically elevated ozone levels, and increased depressive symptoms among adolescents.
Historically, air pollution has been linked to physical health issues like respiratory infections and asthma, but this study is one of the first to explore its effects on mental health, showing that ozone levels can be associated with depressive symptoms in teenagers. Ozone, which is produced when pollutants from vehicles interact with sunlight, tends to be more concentrated closer to the earth’s surface, making it a key indicator of air quality.
Researchers from the University of Denver and Stanford utilized data from an earlier study, comparing it with air quality information from the California Environmental Protection Agency. The original study involved 213 participants aged 9 to 13, who were assessed for mental health conditions over four years. By analyzing the teens’ symptoms alongside air quality data linked to their home addresses, the researchers discovered that higher ozone levels were correlated with worsened depressive symptoms.
Lead researcher Dr. Olivia Bennett emphasized the significance of recognizing air pollution’s impact on mental health as well as physical health. The study defined depressive symptoms as persistent sadness or hopelessness, trouble concentrating, sleep disturbances, and suicidal thoughts. Interestingly, the correlation with anxious-depressive symptoms was not as pronounced as with withdrawn-depressive symptoms.
Although the study does not establish causation between air pollution and depression, it suggests that inflammation caused by ozone and other pollutants could play a role. Adolescents may also be more vulnerable to pollution’s effects since they often spend more time outdoors. Alarmingly, the study found that while certain neighborhoods had elevated ozone levels, they remained below the National Ambient Air Quality Standard of 0.07 ppm. This indicates that even air considered safe can still have adverse effects on teen mental health. Dr. Bennett noted, “It was surprising that the average level of ozone was fairly low even in the communities with relatively higher ozone exposure. This really underscores the fact that even low levels of ozone exposure have potentially harmful effects.”
It’s important to recognize that while this study accounted for various factors such as age, sex, and socioeconomic status, it was conducted within a limited geographical area. More expansive studies are necessary to fully understand the relationship between air quality and adolescent mental health.
In the meantime, some practical measures can be taken to mitigate these issues. The researchers suggest that communities could consider relocating youth sports activities indoors on days with poor air quality, or limiting vehicular traffic during peak pollution times. While these suggestions provide some immediate relief, they only address the symptoms of a larger systemic issue related to air pollution.

Summary
A recent study has found a link between higher ozone levels and increased depressive symptoms in teens, highlighting the need for greater awareness of air pollution’s impact on mental health. While additional research is needed for a comprehensive understanding, practical steps can be taken to protect adolescents from poor air quality effects.
