Reboot and Boost Your Immune System: Sick-Proof Yourself
So find a soap that you love and remember these hand-washing techniques. A reduction in immune response to infections has been demonstrated by older people's response to vaccines. Opt for unsaturated vegetable fats rather than saturated ones from animal foods, which reduce the ability of white blood cells to zap bacteria. Add these omega-3 foods to your diet instead. This opportunity for research based on updated biomedical technology can be employed to give a more complete answer to this and similar questions about the immune system.

7 Ways to Boost Your Immune System for Cold and Flu Season

A rebooted immune system makes you virtually sick-proof. Building and maintaining a bulletproof immune system requires that you adhere to a few basic principles. Are you ready to be sick-proof? The vast majority of your immune system is housed in your gut, which contains both beneficial and harmful microorganisms. When the ratio of harmful to beneficial organisms gets out whack, your body suffers.

In the worst circumstances, this can lead to leaky gut where toxins and other invaders are leached through the lining of the gut and into the blood stream wreaking havoc on your body, causing systemic inflammation, disease, and making you sick colds, flu, etc. Bolstering your gut with beneficial microorganisms is key to maintaining gut health, stabilizing immune function, and reducing systemic inflammation.

While this list is in no particular order, probiotics should absolutely be the number one priority. While I do eat some fermented foods, I prefer to get my probiotics through daily supplementation. Soup made from bones? We talked about how important probiotics are for gut health — well, gelatin is important too. If you think of your immune system as a screen door you can see the importance: Your gut works the same way, letting the nutrients through while containing and eliminating the bad stuff.

Drink bone broth once to twice a week for a bulletproof immune system. You can make your own pretty easy or buy it.

This in turn wreaks havoc on your immune system: Aside from feeding some types of cancer, sugar also feeds the harmful bacteria in your gut.

Additionally, simple sugars, including glucose, table sugar, fructose, and honey caused a fifty percent drop in the ability of white blood cells to engulf bacteria. As a general principle, decline almost everything the government tells you that you must buy from Big Pharma. These programs typically invite people to work out for 45 minutes four to five days a week at pretty high intensity. But the law of diminishing returns is pretty clear in this area. The stress caused by intense, excessive exercise can negatively affect the hypothalamic-pituitary axis, possibly causing conditions such as hypothyroidism.

Another major effect that extreme exercise has on our bodies is an immediate increase in cortisol, the hormone that is released when the body is under stress.

The implied ramification of all of this is completely compromised immune function. Scale it back, gym rats. If you want a bulletproof immune system, you must reboot your schedule and your outlook on work and life. During the holiday season, force yourself to retire to the bedroom an hour earlier than normal. Due to increased stress, weight gain half of annual weight gain occurs during holiday season , reduced access to natural Vitamin D exposure, and so on, your immune system needs all the help it can get.

Anderson Cancer Center in Houston. Sleep your way to a bulletproof immune system. The best way to ensure proper Vitamin D levels is to get plenty of full body sun exposure. Deficiency in vitamin D is associated with increased autoimmunity and an increased susceptibility to infection. A large percentage of the population is already D3 deficient heading into the winter. It may benefit you to supplement with a few other things as well.

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.

Taking megadoses of a single vitamin does not. More is not necessarily better. Walk into a store, and you will find bottles of pills and herbal preparations that claim to "support immunity" or otherwise boost the health of your immune system. Although some preparations have been found to alter some components of immune function, thus far there is no evidence that they actually bolster immunity to the point where you are better protected against infection and disease.

Demonstrating whether an herb — or any substance, for that matter — can enhance immunity is, as yet, a highly complicated matter. Scientists don't know, for example, whether an herb that seems to raise the levels of antibodies in the blood is actually doing anything beneficial for overall immunity. Modern medicine has come to appreciate the closely linked relationship of mind and body. A wide variety of maladies, including stomach upset, hives, and even heart disease, are linked to the effects of emotional stress.

Despite the challenges, scientists are actively studying the relationship between stress and immune function. For one thing, stress is difficult to define. What may appear to be a stressful situation for one person is not for another.

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.

The scientist can only measure things that may reflect stress, such as the number of times the heart beats each minute, but such measures also may reflect other factors. Most scientists studying the relationship of stress and immune function, however, do not study a sudden, short-lived stressor; rather, they try to study more constant and frequent stressors known as chronic stress, such as that caused by relationships with family, friends, and co-workers, or sustained challenges to perform well at one's work.

Some scientists are investigating whether ongoing stress takes a toll on the immune system. But it is hard to perform what scientists call "controlled experiments" in human beings. In a controlled experiment, the scientist can change one and only one factor, such as the amount of a particular chemical, and then measure the effect of that change on some other measurable phenomenon, such as the amount of antibodies produced by a particular type of immune system cell when it is exposed to the chemical.

In a living animal, and especially in a human being, that kind of control is just not possible, since there are so many other things happening to the animal or person at the time that measurements are being taken.

Despite these inevitable difficulties in measuring the relationship of stress to immunity, scientists are making progress. Almost every mother has said it: So far, researchers who are studying this question think that normal exposure to moderate cold doesn't increase your susceptibility to infection. Most health experts agree that the reason winter is "cold and flu season" is not that people are cold, but that they spend more time indoors, in closer contact with other people who can pass on their germs.

But researchers remain interested in this question in different populations. Some experiments with mice suggest that cold exposure might reduce the ability to cope with infection. But what about humans? Scientists have dunked people in cold water and made others sit nude in subfreezing temperatures. They've studied people who lived in Antarctica and those on expeditions in the Canadian Rockies. The results have been mixed. For example, researchers documented an increase in upper respiratory infections in competitive cross-country skiers who exercise vigorously in the cold, but whether these infections are due to the cold or other factors — such as the intense exercise or the dryness of the air — is not known.

A group of Canadian researchers that has reviewed hundreds of medical studies on the subject and conducted some of its own research concludes that there's no need to worry about moderate cold exposure — it has no detrimental effect on the human immune system. Should you bundle up when it's cold outside? The answer is "yes" if you're uncomfortable, or if you're going to be outdoors for an extended period where such problems as frostbite and hypothermia are a risk.

But don't worry about immunity. Regular exercise is one of the pillars of healthy living. It improves cardiovascular health, lowers blood pressure, helps control body weight, and protects against a variety of diseases. But does it help to boost your immune system naturally and keep it healthy? Just like a healthy diet, exercise can contribute to general good health and therefore to a healthy immune system.

It may contribute even more directly by promoting good circulation, which allows the cells and substances of the immune system to move through the body freely and do their job efficiently. Some scientists are trying to take the next step to determine whether exercise directly affects a person's susceptibility to infection. For example, some researchers are looking at whether extreme amounts of intensive exercise can cause athletes to get sick more often or somehow impairs their immune function.

To do this sort of research, exercise scientists typically ask athletes to exercise intensively; the scientists test their blood and urine before and after the exercise to detect any changes in immune system components.
