About  Immune System

The immune system, which consists of a network of organs, proteins and cells that work together to protect your body from harmful bacteria, viruses, and poisons is responsible for our continued good health.

As simple as it may sound, our immune system is a highly complicated network with features and functions that are not completely understood. Continue reading some interesting facts about the immune system.

What is your immune system?

Your body's defensive system is the immune system. It aids in the prevention of infection and sickness. The immune system's function is to fight against invaders, such as:

 

  • Bacteria

  • Viruses

  • Fungi

  • Parasites

  • Cancer cells

  • Pollen

What are the components of your immune system?

Let us understand the immune system's meaning by learning about its components. The immune system comprises numerous components that work together to protect the body against harmful intruders outside. Some essential components are: 

  • White Blood Cells

Leukocytes (white blood cells) move through your bloodstream, tracking and fighting infections and other issues. They generally recall an antigen after fighting and defeating it. Your white blood cells will fight that antigen more rapidly the next time it comes into your body if they remember it.

  • Antibodies

Antibodies are the specialised proteins produced by white blood cells that can destroy or weaken infection-causing pathogens. Antibodies are proteins that go through the bloodstream in search of specific microorganisms. As a result of new infections or vaccinations, the body can produce new antibodies.

  • Organs

The bone marrow and thymus are the main components of the immune system. Because all of the body's blood cells (including T and B lymphocytes) originate in the bone marrow, it is vital to the immune system. T cells go to the thymus, while B lymphocytes remain in the marrow to develop.

  • Lymphatic system

Your lymphatic system is a collection of tissues, veins, and organs that work together to return lymph, a colourless, watery fluid, to blood circulation. Lymph is collected in lymph nodes, which are pea-sized collecting sites. The dead bacteria and cells are filtered away by lymph nodes. If you have an infection, the lymph nodes in your neck and armpits may enlarge. A throat infection, for example, might cause lymph nodes in your neck to enlarge. These are referred to as "swollen glands," yet lymph nodes are not glands.

Fun facts about the immune system

The immune system safeguards you from a variety of illnesses. Several circumstances may harm your immunity. Here are 5 facts about the immune system. 

1. Fever and inflammation are good signs

Some illnesses cause an increase in body temperature, sometimes known as a fever. It is a reaction to your immune system. The temperature rise can kill some bacteria. The body's healing mechanism is also triggered by fever.

The immune system is the host's defensive mechanism that defends it against invading infections. Inflammation is one of the primary mechanisms that alarm the immune system. Still, when this mechanism is disrupted, a long-term chronic inflammation develops, likely to be harmful to the host. An imbalance of circulating inflammatory chemicals is connected to the majority of age-related illnesses.

2. Get more than 5 hours of sleep

The immune system needs sleep to function correctly. Getting enough sleep allows for a well-balanced immune system with robust innate and adaptive immunity, an effective vaccination, and less severe allergy responses.

Serious sleeping difficulties, such as insomnia, circadian rhythm disturbance, and sleep apnea, on the other hand, might impair the immune system's ability to operate correctly.

3. Exposure to sunlight

Humans evolved on a planet with a twenty-four-hour light-dark cycle, and our bodies are designed to operate in tandem with the sun. The synthesis of Vitamin D or calciferol in the skin in response to UVB radiation is one of the most notable instances. This daily amount of Vitamin D not only strengthens our bones and teeth but also influences our immune cells.

Vitamin D is essential for your immunity, and regular sun exposure can boost it. A powerful immune system can help you avoid sickness, infections, certain malignancies, and death following surgery.

4. Stress damages your immune system

Your immune system can be severely harmed by stress as excessive stress releases a stress hormone called cortisol. 

Increased cortisol levels, a steroid hormone crucial for general body functioning, can contribute to various health issues, including lowered immunity.

A stressed individual may engage in harmful activities such as smoking, drinking, or drug usage to cope with stress. These activities also weaken the immune system, leading to headaches, flu-like infections, cardiovascular disease, diabetes, asthma, and stomach ulcers, among other health problems. The following symptoms can identify low immunity:

 

  • Swollen lymph nodes.

  • It is quite easy to contract a cold.

  • Cold sores that recur.

  • Being troubled with a long-term illness.

5. Laughter helps your immune system

Laughter reduces stress hormones while increasing immune cells and infection-fighting antibodies, boosting your illness resistance. Endorphins, the body's natural feel-good chemicals, are released when we laugh.

T cells and NK (natural killer) cells are more active in those who laugh. These strong immune system components work to keep you healthy by fighting off intruders. Laughter can assist in strengthening your immunity by reducing stress and improving NK cell function.

6. Allergies

Allergies arise when your immune system reacts to a foreign substance or food that usually causes no reaction in most individuals, such as pollen, bee venom, or pet dander.

Also, allergic responses occur when your immune system mistakenly perceives something common and completely safe, such as a peanut or shellfish, as dangerous.

Antibodies activate allergy cells and cause histamine to be released into the circulation. Then, depending on what you were exposed to, you may have allergy symptoms ranging from sneezing and an itchy throat to more severe symptoms such as throat swelling.

Keeping your immune system strong

Now that you have been made aware of these immune system facts let's look at how to have a strong immune system. You should follow a healthy lifestyle to boost your immune system, including following these pointers:

 

  • Stop smoking.

  • Fruits and vegetables should make up a large portion of your diet.

  • Regular physical activity.

  • Keep your weight in check.

  • Drink alcohol in moderation.

  • Take adequate sleep. 

  • Include prebiotics and probiotics in your diet.

  • Keep your chronic illness such as diabetes, high blood pressure, and asthma under control.

  • Wash your hands regularly to prevent infections.

  • Reduce your stress levels.

  • Get vaccinated.

Conclusion

Your lifestyle can have an impact on how effectively your immune system defends you against bacteria, viruses, and chronic illness. It is possible to maintain your immune system healthy by replacing harmful health routines with beneficial ones. You can also use an online immunity calculator to keep a check on your immunity score. While you do so, it remains crucial to be ready for the worst situations like medical emergencies. And, what better can help you than a health insurance plan that takes care of your medical costs without draining your savings.
