Young children, exposed to infections for the first time, tend to be symptomatic more than adults. And older adults may find their immune system cannot fight disease as well as it did when they were young.

Scientists are studying direct connections between lifestyle choices and strong immune systems. What we know now is that healthy living is good for overall health and vaccinations are the best supplement available.

Most studies show that dietary supplements are only useful if you have a deficiency in a nutrient. Taking supplements on top of a healthy diet does not add much to your immune system.

Note that most supplements are not superior to the nutrients you can get from food. Studies show the immune system is very responsive to exercise.

Exercise and immune regulation are interrelated and affect each other. Exercise changes immune regulation by affecting cells and has anti-inflammatory effects. Sleep loss reduces natural killer cell activity, which increases the risk for cancer and viral infections; generates production of inflammatory cytokines, which increases the risk for cardiovascular and metabolic disorders; and reduces production of antibodies, which increases the risk for infections.

Stress of all sorts—psychological and physical—directly weakens parts of your immune system, increasing risk for infections or reactivation of viruses inside you. Shingles, a painful rash that arises from the reactivated chickenpox virus, often flares up when people are experiencing chronic stress.

Stress can also cause "patrols" in your immune system—certain cells that tell the immune system to wind down an attack—to fail. When this happens, too much inflammation can occur. Vaccines, also called immunizations, teach the immune system to make antibodies that fight off infections before they make you sick.

Taking zinc supplements at the beginning of a respiratory infection can reduce the severity and duration of symptoms. Ask your doctor to recommend brands and appropriate dose for you.

Yet the design of our immune system is complex and influenced by an ideal balance of many factors, not just diet, and especially not by any one specific food or nutrient. However, a balanced diet consisting of a range of vitamins and minerals, combined with healthy lifestyle factors like adequate sleep and exercise and low stress, most effectively primes the body to fight infection and disease. On a daily basis, we are constantly exposed to potentially harmful microbes of all sorts. Our immune system, a network of intricate stages and pathways in the body, protects us against these harmful microbes as well as certain diseases.
