Climate Change Amplifies Symptoms for Millions with Chronic Health Conditions

Living in Chicago during successive wildfire seasons, the writer describes how dense smoke and an AQI of 753 triggered headaches, sore throat and heightened arthritis pain. She lists six chronic conditions she manages and explains that weather patterns uniquely affect each disease, with lupus patients avoiding sun while others find relief. Scientific findings are presented that tie inhaled particulate matter to rheumatic diseases, new cases of rheumatoid arthritis, and possible triggers for multiple sclerosis, Parkinson's, diabetes and asthma.

Floods generate mold spores and expose people to lead and asbestos, further aggravating illnesses such as long Covid and myalgic encephalomyelitis. Heat waves, already responsible for roughly 10,000 deaths in Europe, strain cardiovascular and thyroid conditions and may weaken immune barriers, increasing allergy and autoimmunity risk. Climate-driven shifts in humidity and temperature expand the habitats of ticks and mosquitoes, raising the threat of West Nile, Lyme, dengue and other vector-borne diseases, while warmer conditions accelerate food-borne pathogens like salmonella and cyclospora. The author concludes that, despite the impossibility of reversing past emissions, investing in agencies like the CDC, FDA and NOAA, along with universal health care and resilient infrastructure, is essential to safeguard public health.
