Exposure to air pollution during pregnancy is linked to adverse birth outcomes and has now been found to nearly quadruple the risk of postpartum depression. A study revealed that exposure to nitrogen dioxide and inhalable particulate matter during pregnancy can increase the risk of postpartum depression for up to three years. The research followed 361 expectant mothers and found that those exposed to higher levels of pollution had a significantly higher risk of depression. This study suggests that there may be more cases of postpartum depression than previously reported and emphasizes the importance of seeking help for persistent symptoms.
