One caveat—balance is required. You may read or hear about a food or habit that boosts the immune system, but go overboard with your response.

Overdosing on anything, even if it is natural, throws the body-mind out of balance. Here are a couple of my favorite natural immune boosters, and how to get the right amount of them.

During moderate exercise, immune cells circulate through the body more quickly enabling them to better kill viruses and bacteria.

After exercise ends, the immune system response seems to return to normal after a few hours. However, consistent moderate exercise keeps the immune response working longer.

There is a caveat. Evidence suggests that too much intense exercise can have the opposite effect and reduce the immune response.

Research shows that more than 90 minutes of high intensity endurance exercise a day can leave individuals susceptible to illness for up to 72 hours. Because too much intense exercise can decrease in immune response, balance is required.
