7 Ways to Boost Your Immune System

Get a Workout

Even though the temperatures are cooler, you can still exercise outside in the winter. Just make sure you dress in layers and use common sense! An outdoor walk or hike in the snow is great exercise, and study after study shows that getting a workout is good for immune function. Researchers aren’t sure exactly how exercise strengthens your immune system, but they do know that people who exercise have better-functioning white blood cells. Your body makes millions of white blood cells every day. These cells constantly patrol your body, destroying germs. Strong white blood cells make for better immune system function. Experts also think that physical activity can flush bacteria from your lungs, and that the rise in your body’s temperature may prevent bacterial growth. In addition, exercise has been shown to slow down your body’s release of stress-related hormones. At the same time, it allows your body to release endorphins — natural hormones that promote a sense of relaxation and well-being. Endorphins help you fight stress and sleep better, too — a win-win for immune health.
