  • Stress Wrecks Intestinal Bacteria, Could Keep Immune System on Idle
    Stress not only sends the human immune system into overdrive – it can also wreak havoc on the trillions of bacteria that work and thrive inside our digestive system. New research suggests that this may be important because those bacteria play a significant role in ...More
