Practical strategies for bolstering the immune system and combating illness
How can you improve your immune system? Your immune system does an outstanding job protecting you from disease-causing microorganisms. Occasionally, it fails, and a pathogen successfully invades and causes illness. Is it possible to stimulate the immune system through intervention? What if you consume a more nutritious diet? Take particular vitamins or herbal supplements? Should you alter your lifestyle to produce a near-perfect immune response?
How Can You Strengthen Your Immune System?
Increasing immunity is appealing, but the capacity to do so has yet to discover for several reasons. The immune system is indeed a system and not a singular entity. To function correctly, equilibrium and harmony are required. Regarding the complexity and interconnectedness of the immune response, there is still much that researchers still need to understand. There are no scientifically-proven lifestyle-immune function links.
However, lifestyle influences on the immune system are fascinating and should be studied. Researchers are examining how diet, exercise, age, anxiety, and other factors affect human and animal immune systems. In the interim, general strategies for a healthy lifestyle make sense because they will likely improve immune function and come with other established health benefits.
Healthy Ways To Strengthen Your Immune System
Choosing a healthful lifestyle should be your first line of defense. Following general health recommendations is the most effective way to maintain a healthy immune system naturally. Every part of your body, including your immune system, functions better when it is shielded from environmental intrusions and supported by healthy-living practices such as the following:
- Avoid smoking.
- Consume an abundance of fruits and vegetables.
- Regular exercise is encouraged.
- Uphold a healthy weight.
- If you consume alcohol, do so in moderation.
- Get enough slumber.
- Take precautions against infection, such as frequent hand cleansing and thoroughly cooking meats.
- Attempt to reduce tension.
Maintain all recommended immunizations. Vaccines prime the immune system to combat infections before establishing themselves in the body.
Increase Immunity The Healthy Way.
Numerous items on store displays claim to enhance or support the immune system. However, the concept of boosting immunity needs more scientific logic. Increasing the number of cells in your body, whether immune or other types, is not necessarily positive. For instance, athletes who engage in “blood doping” — injecting blood into their systems to increase the number of blood cells and enhance performance — risk suffering strokes.
Attempting to increase the number of immune system cells is exceptionally difficult due to the wide variety of immune system cells that respond in various ways to various microorganisms. Which cells should multiply, and to what extent? Scientists do not currently know the solution. It is known that the body generates immune cells continuously. It produces far more lymphocytes than it can conceivably utilize. The excess cells eliminate themselves through apoptosis, a natural cell death process before and after the battle. No one knows the optimal number or composition of immune system cells required for optimal function.
Immune System And Age
Our immune response capability declines with age, contributing to increased infections and malignancy. As life expectancy has risen in developed nations, so has the incidence of age-related conditions.
Some people age well, but several studies show that the elderly are more prone to get infectious diseases and, more importantly, die from them. The top cause of death for 65-year-olds globally is respiratory infections like influenza, COVID-19, and pneumonia. Scientists have linked this increased risk to decreasing T cells, likely due to the thymus atrophying with age and producing fewer T cells to combat infection. This decrease in thymus function may not explain the decline in T cells, but other alterations may. Others wonder if bone marrow becomes less efficient at making immune system stem cells.
The response of elderly individuals to vaccines has demonstrated a diminished immune response to infections. For instance, investigations of influenza vaccines have revealed that the vaccine is less effective for individuals over 65 compared to healthy children (over the age of 2). Nevertheless, vaccinations for influenza and S. pneumoniae have substantially reduced the rates of illness and death among older people compared to the absence of vaccination.
Older people appear to have a connection between nutrition and immunity. “Micronutrient malnutrition” is a type of malnutrition that is remarkably prevalent even in wealthy nations. Older people can experience micronutrient malnutrition, a deficiency in specific essential vitamins and trace minerals obtained through diet or supplementation. Older individuals typically consume less food and have a diet with less variety. A significant concern is whether or not dietary supplements can help older individuals maintain a healthier immune system. Older people should discuss this issue with their physician.
Diet And Your Immune System
Like any other combat force, the immune system army marches on its stomach. Warriors with a healthy immune system require excellent, consistent nutrition. Scientists have long recognized that poor and malnourished individuals are more susceptible to infectious diseases. For example, researchers do not know whether specific dietary factors, such as high ingestion of processed foods or simple sugar, will harm immune function. Human nutrition’s effects on the immune system have been the subject of comparatively few studies.
Micronutrient deficits such as zinc, selenium, copper, iron, folic acid, and vitamin A, vitamin B6, vitamin C, and E may change animals’ immunological responses in test tubes. The effect of these immune system abnormalities on animal health needs to be clarified, and the impact of similar impairments on the human immune response is unknown.
How can you proceed? Taking a regular multivitamin and mineral pill may enhance your resistance to infection and improve your health if you despise vegetables. Megadoses of one vitamin don’t work. More doesn’t always mean better.
Improve Immunity With Herbs And Supplements?
You can find bottles of tablets and herbal preparations in stores that claim to “support immunity” or otherwise improve the health of your immune system. Even though some practices have been found to modify some aspects of immune function, there is no evidence that they enhance immunity to the point where you are best protected from infection and disease. Until now, proving that a herb — or any substance, for that matter — can boost immunity is a highly complex matter. Scientists do not know, for instance, whether a herb that appears to increase antibodies in the blood enhances the immune system.
Stress And Immune Function
Modern medicine has evolved to recognize the intimate connection between mind and body. Emotional tension has been linked to many ailments, such as stomach upset, hives, and even heart disease. Despite obstacles, scientists continue investigating the connection between stress and immune function.
For starters, it is challenging to define tension. A situation that appears stressful to one individual may not be stressful to another. When people expose to what they perceive to be stressful situations, it is difficult for them to measure the amount of stress they experience. It is also tricky for scientists to determine whether a person’s subjective impression of the amount of pressure is accurate. The scientist can only measure variables that may reflect tension, such as the number of heartbeats per minute, but these variables may also reflect other factors.
The majority of scientists studying the relationship between stress and immune function, however, do not look at a sudden, short-lived stressor; instead, they attempt to learn more constant and frequent stressors known as chronic stress, such as those caused by relationships with family, friends, and co-workers, or by sustained challenges to perform well at one’s job. Some researchers are investigating whether chronic stress harms the immune system.
Performing “controlled experiments” on humans is difficult. A scientist can change a single factor, like the amount of a chemical, and then measure the effect on another measurable phenomenon, like the number of antigens produced by a specific immune system cell when subjected to the chemical. Because measurements involve so many other things, this form of control is unachievable in live animals, especially humans.
Despite these inevitable obstacles, scientists are progressing in measuring the relationship between stress and immunity.
