"Hot Weather's Impact on Immune System and Heart Health"

A study presented at the American Heart Association’s conference suggests a link between hot weather and the body's immune response, including increased levels of certain blood cells and indicators of inflammation. The research, which looked at blood samples from 624 participants in Louisville, is considered preliminary but offers insight into potential treatments to protect people from the health risks associated with high temperatures, such as heart attack and stroke. The study's lead researcher plans to further investigate the long-term effects of extreme heat events on immune responses and inflammation, as well as explore whether tree-planting could mitigate the effects on the immune system.
