Your Immune System: How Does It Work?

Your immune system is a network of cells, tissues and organs that work together to defend your body from harmful germs. In other words, it’s your body’s way of protecting itself from infection and disease – fighting everything from cold and flu viruses to serious conditions like cancer. Your immune system sounds the alarm so your body knows when it’s time to release antibodies to fight off invading germs.

10 Ways to Enhance Your Immunity

There is a wealth of information online about what you can do to boost your immunity, and as with any topic on the internet, some of it is credible and some of it isn’t.

While we can’t control when our lives become stressful, we can incorporate tools to help lower our stress levels, including mindfulness and meditation activities. Even a few minutes of deep breathing or another breathing technique may help you relax and reduce your stress.

A healthy lifestyle can help every part of your body function better, including your immune system. Give your body its best chance to fight off infections.
