The immune system also restricts tumors and cancerous growths inside the body. However, problems with the immune system can lead to illnesses and infections. Immune responses can be weakened by various external influences.

Click on NEXT to find out the top 11 things that can weaken your immune system. P eople like to ignore it but stress has a major influence on your immune system.

Chronic stress -- caused by stressful situations or events that last over a long period of time -- raises cortisol levels of the body which decreases the production of 'good' prostaglandins. Chronic stress can make you more susceptible to colds and the flu, as well as more serious health problems like heart disease, diabetes and other diseases.

By practicing stress-reducing activities like yoga, meditation and laughter, you can keep your body from going into chronic stress mode. P rolonged and excessive consumption of refined sugars and highly processed foods containing pesticides, chemical additives, and preservatives can weaken the immune system and make you vulnerable to developing chronic conditions. A study published in the American Journal of Clinical Nutrition found that the ability of white blood cells to kill bacteria is significantly hampered for up to 5 hours after eating gm of sugar equivalent to three cans of sweetened soft drink.

A lcohol, like sugar, consumed in excess can reduce the ability of white blood cells to kill germs. Damage to the immune system increases in proportion to the quantity of alcohol consumed. In the long term, alcohol can impede the functioning of immune cells, increasing your susceptibility to infectious diseases and cancer. W ithout adequate sleep, the immune system doesn't get a chance to rebuild, and it becomes weak. Poor sleep is associated with reduced number of T-cells, white blood cells that help the body fight disease.

Many studies show that people who don't get a good night's sleep or who don't get enough sleep sleeping under seven hours a night are more likely to get sick after being exposed to a virus, such as the common cold. O besity can lead to a weakened immune system. It can affect the ability of white blood cells to multiply, produce antibodies, and prevent inflammation.

A study conducted by new University of North Carolina at Chapel Hill School of Medicine on laboratory mice shows that obesity reduces the body's ability to turn on elements of its immune systems needed for controlling influenza infection. D uring moderate exercising, blood flow increases which promotes the process of expelling toxic waste out of your body.

The improved blood circulation also promotes circulation of antibodies and white blood cells that are important for fighting off infections. As little as 20 minutes of walking five days a week can help your immune system perform at its best.

S ome prescription and non-prescription drugs are major toxins that many put into their bodies. Excessive use of antibiotics and cold and fever fighting medications weakens your immune system. Researchers found that certain people taking antibiotics had reduced levels of cytokines -- the hormone messengers of the immune system.

You are more likely to develop resistant bacteria or become sick in the future when your immune system is suppressed.

L ack of proper hygiene habits exposes your body to more germs thus leading to a weak immune system. Habits like brushing your teeth twice daily, washing your hands properly before eating and keeping your nails neat and tidy can go a long way keeping infections at bay.

C igarettes contain over 4, chemicals, all of which are extremely toxic to the body. And, more the amount of toxic substance in your body, weaker is the immune system.

But when we have an under- or over-active immune system, we are at a greater risk of developing infections and other health conditions.

The cells of the immune system originate in the bone marrow, then migrate to guard the peripheral tissues, circulating in the blood and in the specialized system of vessels called the lymphatic system. Underactivity of the immune system results in severe infections and tumors of immunodeficiency, while overactivity results in allergic and autoimmune diseases.

When the cells of the immune system detect the presence of an antigen, the immune system recalls stored memories in order to quickly defend itself against known pathogens. Before learning exactly how to boost your immune system, first understand that most immune disorders result from either an excessive immune response or an autoimmune attack.

Disorders of the immune system include:. When the body overreacts to an allergen, such as dust, mold or pollen, it causes an immune reaction that leads to the development of allergy symptoms. Allergies and asthma is a growing epidemic, affecting people of all ages, races, genders and socioeconomic statuses. A person becomes allergic to a substance when the body develops antigens against it and has a reaction upon repeated exposure to that substance.

An immune deficiency disease is when the immune system is missing one or more of its parts, and it reacts too slowly to a threat. Immune deficiency diseases can be caused by medications or illness, or it may be a genetic disorder, which is called primary immunodeficiency.

All of these conditions are due to a severe impairment of the immune system, which leads to infections that are sometimes life-threatening. Autoimmune diseases have registered an alarming increase worldwide since the end of the Second World War, with more than 80 autoimmune disorders and increases in both the incidence and prevalence of these conditions.

In fact, it often takes about five years to receive a diagnosis because autoimmune disease symptoms are so disparate and vague. Several studies have shown that increased intestinal permeability is associated with several autoimmune diseases, and it appears to be involved in disease pathogenesis. When searching for how to boost your immune system, look to these 10 herbs, supplements and essential oils. Research shows that one of the most significant echinacea benefits is its effects when used on recurring infections.

A study published in Evidence-Based Complementary and Alternative Medicine found that echinacea showed maximal effects on recurrent infections, and preventive effects increased when participants used echinacea to prevent the common cold. A study conducted at the University of Wisconsin Medical School found that echinacea demonstrates significant immunomodulatory activities. After reviewing several dozen human experiments, including a number of blind randomized trials, researchers indicate that echinacea has several benefits, including immunostimulation, especially in the treatment of acute upper respiratory infection.

The berries and flowers of the elder plant have been used as medicine for thousands of years. He used elderberry because of its wide array of health benefits, including its ability to fight colds, the flu, allergies and inflammation. Several studies indicate that elderberry has the power to boost the immune system, especially because it has proven to help treat the symptoms of the common cold and flu.

A study published in the Journal of International Medical Research found that when elderberry was used within the first 48 hours of onset of symptoms, the extract reduced the duration of the flu, with symptoms being relieved on an average of four days earlier. Plus, the use of rescue medication was significantly less in those receiving elderberry extract compared with placebo. Dating back to ancient times, silver was a popular remedy to stop the spread of diseases. Silver has historically and extensively been used as a broad-spectrum antimicrobial agent.

To experience colloidal silver benefits , it can be used in several ways. Simply take one drop of true colloidal silver with internally.

Probiotics are good bacteria that help you digest nutrients that boost the detoxification of your colon and support your immune system. Research published in Critical Reviews in Food Science and Nutrition suggests that probiotic organisms may induce different cytokine responses. Supplementation of probiotics in infancy could help prevent immune-mediated diseases in childhood by improving the gut mucosal immune system and increasing the number of immunoglobulin cells and cytokine-producing cells in the intestines.

Although astragalus is one of the least studied immune-boosting herbs, there are some preclinical trials that show intriguing immune activity. Researchers concluded that astragalus extract has a beneficial effect on the immune system, and it protects the body from gastrointestinal inflammation and cancers.

Ginger root and ginger essential oil can treat a wide range of diseases with its immunonutrition and anti-inflammatory responses. Research shows that ginger has antimicrobial potential, which helps in treating infectious diseases.
