“Bodily fluids carry your immune cells throughout your body and staying hydrated helps them get where they need to go to fight off infections,” says Abbott research scientist Jennifer Williams. She explains that water is a critical component of lymph, a clear-to-white fluid that contains many of the white blood cells, including lymphocytes, that attack invaders in the blood to help you fight off illness.
Water helps to oxygenate the blood and that pumps up our cells and helps them function at full capacity. Healthy, happy cells that are packed with oxygen allows our bodies to enjoy a superior immunity.
