This doesn’t necessarily mean dangerous infections—many parasites can be present without causing obvious symptoms at first. But understanding how they work inside the body can empower you to support your health

Why Many Parasites Prefer Low-Oxygen Zones Parasites don’t just hide randomly in the body. Many have adapted to thrive in low-oxygen zones , such as the gut lumen, deeper tissue layers, or stagnant lymphatic areas. These environments provide relative safety, as immune surveillance and detox signaling are often weaker. A key survival strategy for these organisms is anaerobic metabolism . In low-oxygen conditions, parasites switch from typical oxygen-dependent energy pathways t
