"Hot Weather's Impact: Inflammation, Immune System, and Heart Health"

Exposure to high heat may impair the immune system's ability to fight infections and increase inflammation, potentially accelerating the progression of cardiovascular disease, according to preliminary research presented at the American Heart Association’s Epidemiology and Prevention│Lifestyle and Cardiometabolic Scientific Sessions 2024. The study found that even minor exposure to high temperatures led to changes in immune markers, particularly affecting the body's innate immune system and adaptive immune system. The findings highlight the potential health impact of rising global temperatures and the need for increased awareness and precautions, especially for older adults and those with existing cardiovascular disease.
