Maine is under a double environmental health advisory this week, and long-term care facilities should be taking both seriously. The Maine CDC has developed a clinical guidance document for health care providers.  The National Weather Service has issued Extreme Heat Watches, Warnings, and Advisories across much of the state, with heat index values expected to reach 100–110°F. At the same time, the Maine Department of Environmental Protection has issued an air quality advisory for elevated ground-level ozone, reaching the "Unhealthy for Sensitive Groups" level along the coast from Kittery to Acadia National Park, with moderate ozone and wildfire-related particle pollution affecting much of the rest of the state. Maine CDC State Epidemiologist Dr. Isaac Benowitz issued a High Priority Public Health Advisory on July 1 specifically noting that combined exposure to heat and ozone produces additive health impacts — meaning the risks compound, not just add.

Nursing home and residential care residents are squarely in the highest-risk category for both: older adults, individuals with respiratory conditions like asthma or COPD, and those with cardiovascular disease are the populations most vulnerable to heat illness and ozone exposure. Facilities should ensure that outdoor activities are limited or moved indoors, that air conditioning is functioning and accessible to all residents, and that clinical staff are monitoring early signs of heat-related illness and respiratory exacerbation. Residents with asthma should have quick-relief medications readily accessible. The Maine DEP Air Quality Hotline (1-800-223-1196) and the Maine DEP Air Quality Forecast are good real-time resources.
