About this episode
Story at-a-glance Inhaling microplastics disrupts your lung's immune defenses within 24 hours by disabling macrophages, the cells that normally clear out pathogens and waste Once inhaled, plastic particles travel beyond your lungs and accumulate in your liver, brain, kidneys, and colon, raising your risk for inflammation and chronic disease Your body's immune cells cannot break down microplastics and instead hold onto them, causing ongoing immune dysfunction and toxic buildup Researchers are now working to identify early warning signs of microplastic-induced lung damage, including biomarkers that signal rising cancer risk You can lower your daily exposure by filtering your air and water, switching to plastic-free kitchen tools and balancing related hormonal disruption with natural progesterone if needed
