How can I make my immune system stronger?

The short answer: If there was a way to boost your immunity, I wouldn't be writing this article.

As enticing as it is, the ability to boost your immunity has proved elusive.

Quite often, manipulating one factor of the immune response can have a negative effect on another system in the body.

While there are no scientifically proven links between lifestyles or supplements on enhanced immune function, there are preliminary data to support that a healthy diet, adequate sleep, moderate exercise and decreased psychological stress can help prevent ones susceptibility to getting sick. Unfortunately, there's not one factor that has unequivocally proven to protect one against the cold or flu.
