When people are exposed to situations they regard as stressful, it is difficult for them to measure how much stress they feel, and difficult for the scientist to know if a person's subjective impression of the amount of stress is accurate. Migraine relief found with 3 valuable nutrients August 27, How herbal medicine and lifestyle changes can help, study says September 16, The answer is regular exercise. But what about humans? So far, researchers who are studying this question think that normal exposure to moderate cold doesn't increase your susceptibility to infection. Is it possible to intervene in this process and boost your immune system?

In fact, boosting the number of cells in your body — immune cells or others — is not necessarily a good thing. For example, athletes who engage in "blood doping" — pumping blood into their systems to boost their number of blood cells and enhance their performance — run the risk of strokes. Attempting to boost the cells of your immune system is especially complicated because there are so many different kinds of cells in the immune system that respond to so many different microbes in so many ways.
Which cells should you boost, and to what number? So far, scientists do not know the answer. What is known is that the body is continually generating immune cells.
Certainly it produces many more lymphocytes than it can possibly use. The extra cells remove themselves through a natural process of cell death called apoptosis — some before they see any action, some after the battle is won.
No one knows how many cells or what the best mix of cells the immune system needs to function at its optimum level. What can improve your mood, boost your ability to fend off infection, and lower your risk for heart disease, diabetes, high blood pressure, and colon cancer?
The answer is regular exercise. It may seem too good to be true, but it's not. Hundreds of studies demonstrate that exercise helps you feel better and live longer. This report answers many important questions about physical activity. It will also help guide you through starting and maintaining an exercise program that suits your abilities and lifestyle. As we age, our immune response capability becomes reduced, which in turn contributes to more infections and more cancer.
As life expectancy in developed countries has increased, so too has the incidence of age-related conditions. While some people age healthily, the conclusion of many studies is that, compared with younger people, the elderly are more likely to contract infectious diseases and, even more importantly, more likely to die from them. Respiratory infections, influenza, and particularly pneumonia are a leading cause of death in people over 65 worldwide. No one knows for sure why this happens, but some scientists observe that this increased risk correlates with a decrease in T cells, possibly from the thymus atrophying with age and producing fewer T cells to fight off infection.
Whether this decrease in thymus function explains the drop in T cells or whether other changes play a role is not fully understood.
Others are interested in whether the bone marrow becomes less efficient at producing the stem cells that give rise to the cells of the immune system. A reduction in immune response to infections has been demonstrated by older people's response to vaccines.
For example, studies of influenza vaccines have shown that for people over age 65, the vaccine is much less effective compared to healthy children over age 2. But despite the reduction in efficacy, vaccinations for influenza and S.
There appears to be a connection between nutrition and immunity in the elderly. A form of malnutrition that is surprisingly common even in affluent countries is known as "micronutrient malnutrition. Older people tend to eat less and often have less variety in their diets. One important question is whether dietary supplements may help older people maintain a healthier immune system.
Older people should discuss this question with a physician who is well versed in geriatric nutrition, because while some dietary supplementation may be beneficial for older people, even small changes can have serious repercussions in this age group. Like any fighting force, the immune system army marches on its stomach. Healthy immune system warriors need good, regular nourishment. Scientists have long recognized that people who live in poverty and are malnourished are more vulnerable to infectious diseases.
Whether the increased rate of disease is caused by malnutrition's effect on the immune system, however, is not certain. There are still relatively few studies of the effects of nutrition on the immune system of humans, and even fewer studies that tie the effects of nutrition directly to the development versus the treatment of diseases. There is some evidence that various micronutrient deficiencies — for example, deficiencies of zinc, selenium, iron, copper, folic acid, and vitamins A, B6, C, and E — alter immune responses in animals, as measured in the test tube.
However, the impact of these immune system changes on the health of animals is less clear, and the effect of similar deficiencies on the human immune response has yet to be assessed. So what can you do? If you suspect your diet is not providing you with all your micronutrient needs — maybe, for instance, you don't like vegetables — taking a daily multivitamin and mineral supplement may bring other health benefits, beyond any possibly beneficial effects on the immune system.
