"Quick Immune Boost: 15-Minute Strategies"

New research suggests that just 15 minutes of moderate exercise can significantly boost the immune system by increasing concentrations of Natural Killer (NK) cells in the bloodstream, which are responsible for seeking out and destroying disease-causing microbes and potentially cancerous cells. A study from the University of Houston found that NK cell levels increased significantly after 15 minutes of moderate intensity exercise on a stationary bike, with no further increases seen at the 30-minute mark. These findings indicate that the immune-boosting benefits of exercise can be achieved in a short amount of time, challenging the conventional wisdom that longer workouts are necessary for immune system optimization.
