High Pollen Counts Linked To Increased Suicide Risk, Research Shows

University Of Michigan researchers found a significant connection between airborne pollen levels and suicide rates across the United States. The study analyzed nearly 500,000 suicides from 2006 to 2018 alongside daily pollen counts from 186 counties in 34 metropolitan areas. Lead researcher Joelle Abramowitz reported suicide risk increased 7.4% during the highest pollen days, 5.5% at third-highest levels, and 4.5% at second-tier counts compared to lowest pollen periods. People with existing mental health conditions faced nearly 9% higher suicide risk on peak pollen days. “Based on our incremental data, we estimate that pollen may have been a contributing factor in up to 12,000 of those deaths over the period, or roughly 900 to 1,200 deaths per year,” Abramowitz stated. She noted “a small shock could have a big effect if you’re already in a vulnerable state.” (Story URL)
