Crucial ways you can support a healthy immune system

Exercise, sleep, stress reduction, and a healthy diet play important roles in protecting health.

If only there were a pill that could keep the immune system in top shape. You could take the pill every day and feel more protected against viruses, infectious bacteria, and other bugs that threaten health. It would be a simple and easy solution.

Too bad the only "pill" we have to maintain robust immune health is one that many people find hard to swallow. It's not a vitamin or an herb — the evidence that those things ramp up protection just isn't there. Instead, it's a combination of healthy lifestyle habits.
