Getting good sleep can strengthen your immune system by aiding the T cells to destroy cells infected by viruses and other pathogens. By Alex Osiadacz. Xie, J.

Immune system maintenance -

Examples of diseases that compromise the immune system, reducing its ability to work and leaving the patient susceptible to infections, include:. Treatments for these diseases depends on the underlying condition. Typically, drugs like antibiotics, antiviral and anti-fungal medications are given for each infection.

Immunoglobulin therapy and antiretroviral drugs may also be used. In severe cases, bone marrow transplants might be ordered.

As we get older, our immune systems begin to lose some of their potency, increasing the risk of disease and cancer. This is why countries with higher life expectancies tend to have a greater incidence of age-related conditions.

Research indicates that, compared to young people, older persons are more likely to contract infectious diseases, and are also more likely to die from them. On an immune level, the body starts to reduce the production of helper T cells and B cells also known as primary lymphocytes as we age.

This is thought to be due to changes in stem cells, local tissue, and systemic environments, and it results in an increased occurrence of immune system stress. The leading causes of death of people over the age of 65 tend to be heart disease, cancer, strokes, and respiratory diseases.

Around the world, researchers are working on potential therapies to combat the decline in immune function in the elderly.

One leading theory has to do with a form of malnutrition, especially in wealthy countries where life expectancy is high. This is micronutrient deficiency — in which a person becomes deficient in essential vitamins or trace minerals as a result of their diet.

Micronutrients act as cofactors for enzymes and are vital for a healthy, strong immune system. As older people tend to eat less varied diets, they may risk becoming deficient in certain micronutrients, which can negatively impact the immune system.

Today, on-going stress is recognized as a key risk factor for increasing the likelihood of developing a disease, due to its effect in dampening our immune systems. It is essential for us to make healthy lifestyle changes in order to boost our immune systems as much as possible. Key strategies to reduce immune system stress include adequate sleep, regular exercise, immunization, and good nutrition.

Research has revealed that increasing intakes of specific nutrients including zinc, vitamin A, selenium, vitamin D, and glutamine, may significantly enhance immune function. To increase levels of these nutrients consumed, a balanced diet rich in fruits and vegetables is recommended.

In conjunction with a healthy diet, a daily multivitamin containing these micronutrients should also be considered, especially during times of increased stress. Given the immune-enhancing effects of adequate sleep, regular exercise, and good nutrition, these factors should collectively be recognized as fundamental parts of our 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. Eating a good quality diet, as depicted by the Healthy Eating Plate, can prevent deficiencies in these nutrients.

However, there are certain populations and situations in which one cannot always eat a variety of nutritious foods, or who have increased nutrient needs. In these cases a vitamin and mineral supplement may help to fill nutritional gaps.

Studies have shown that vitamin supplementation can improve immune responses in these groups. The elderly are a particularly high-risk group. The immune response generally declines with increasing age as the number and quality of immune cells decreases.

This causes a higher risk of poorer outcomes if the elderly develop chronic or acute diseases. In addition, about one-third of elderly in industrialized countries have nutrient deficiencies. Diet variety may also be limited due to budget constraints or lower interest in cooking for one person; poor dentition; mental impairment; or lack of transportation and community resources to obtain healthy food.

Megadose supplements many times the RDA do not appear justified, and can sometimes be harmful or even suppress the immune system e. Remember that vitamin supplements should not be considered a substitute for a good diet because no supplements contain all the benefits of healthful foods.

What Is Our Immune System? These barriers include: Skin that keeps out the majority of pathogens Mucus that traps pathogens Stomach acid that destroys pathogens Enzymes in our sweat and tears that help create anti-bacterial compounds Immune system cells that attack all foreign cells entering the body Adaptive or acquired immunity is a system that learns to recognize a pathogen.

Other conditions that trigger an immune response Antigens are substances that the body labels as foreign and harmful, which triggers immune cell activity.

What factors can depress our immune system? Older age: As we age, our internal organs may become less efficient; immune-related organs like the thymus or bone marrow produce less immune cells needed to fight off infections.

Aging is sometimes associated with micronutrient deficiencies, which may worsen a declining immune function. Environmental toxins smoke and other particles contributing to air pollution, excessive alcohol : These substances can impair or suppress the normal activity of immune cells.

Excess weight: Obesity is associated with low-grade chronic inflammation. Fat tissue produces adipocytokines that can promote inflammatory processes. Chronic diseases: Autoimmune and immunodeficiency disorders attack and potentially disable immune cells.

Chronic mental stress: Stress releases hormones like cortisol that suppresses inflammation inflammation is initially needed to activate immune cells and the action of white blood cells.

Lack of sleep and rest: Sleep is a time of restoration for the body , during which a type of cytokine is released that fights infection; too little sleep lowers the amount of these cytokines and other immune cells. Does an Immune-Boosting Diet Exist?

Probiotic foods include kefir, yogurt with live active cultures, fermented vegetables, sauerkraut, tempeh, kombucha tea, kimchi, and miso. Prebiotic foods include garlic, onions, leeks, asparagus, Jerusalem artichokes, dandelion greens, bananas , and seaweed.

The complement system is made up of proteins whose actions complement the work done by antibodies. The lymphatic system is a network of delicate tubes throughout the body.

The main roles of the lymphatic system are to:. The spleen is a blood-filtering organ that removes microbes and destroys old or damaged red blood cells.

It also makes disease-fighting components of the immune system including antibodies and lymphocytes. Bone marrow is the spongy tissue found inside your bones. It produces the red blood cells our bodies need to carry oxygen, the white blood cells we use to fight infection, and the platelets we need to help our blood clot.

The thymus filters and monitors your blood content. It produces the white blood cells called T-lymphocytes. As well as the immune system, the body has several other ways to defend itself against microbes, including:.

A rise in body temperature, or fever , can happen with some infections. This is actually an immune system response. A rise in temperature can kill some microbes. Fever also triggers the body's repair process. It is common for people to have an over- or underactive immune system.

Overactivity of the immune system External Link can take many forms, including:. An underactive immune system does not function correctly and makes people vulnerable to infections. It can be life threatening in severe cases.

People who have had an organ transplant need immunosuppression treatment to prevent the body from attacking the transplanted organ.

Immunoglobulins commonly known as antibodies are used to treat people who are unable to make enough of their own, or whose antibodies do not work properly.

This treatment is known as immunoglobulin replacement therapy IRT External Link. Until recently, immunoglobulin therapy in Australia mostly involved delivery of immunoglobulins through a drip into the vein — known as intravenous immunoglobulin IVIg therapy.

Now, subcutaneous immunoglobulin SCIg therapy External Link can be delivered into the fatty tissue under the skin, which may offer benefits for some patients.

This is known as subcutaneous infusion or SCIg therapy. Subcutaneous immunoglobulin is similar to intravenous immunoglobulin. It is made from plasma — the liquid part of blood containing important proteins like antibodies.

Download the Subcutaneous Immunoglobulin - information sheet for patients External Link to read more about this type of treatment. Many health services are now offering SCIg therapy to eligible patients with specific immune conditions.

Immunisation works by copying the body's natural immune response. A vaccine a small amount of a specially treated virus, bacterium or toxin is injected into the body. The body then makes antibodies to it. If a vaccinated person is exposed to the actual virus, bacterium or toxin, they won't get sick because their body will recognise it and know how to attack it successfully.

Vaccinations are available against many diseases, including measles and tetanus. The immunisations you may need are decided by your health, age, lifestyle and occupation.
