Immune system

Why we read this article?

We are facing a great pandemic situation currently, we all know it’s name “coronavirus”. To fight from this unwanted guest which is wondering around us and it invades on our body anytime if our body is not well suited like IRON MAN currently, we are not discussing about Iron man suit we are discussing about our internal suit Immune System. If we all not well-protected ourselves then can’t fight with corona our any type of disease which directly invade of the immune system. This article helps you to know about the immune system, how it works, how much it helps us to fight with covid19 or any disease. I hope this article will help you a lot and after reading this article you didn’t need to read further reading any article.

What is Immune system?

First of all, we need to know what we are discussing. So let's start with what is the Immune System. The Immune System is a complex network of protein and cell that protect our body from foreign infection, fight with them and keep their record of fighting for future invade in a type of white blood corpuscles (WBC) that is known as a memory cell. This means if any microbe invades on our body then it quickly killed them and also remember how to kill them another time if invade. The immune system is made up of special organs, cells and chemicals that fight infection (microbes). The main parts of the immune system are white blood cells, antibodies, the complement system, the lymphatic system, the spleen, the thymus, and the bone marrow.

How Immune system work?

There are three lines of defence which are present in our body, the first being outer barriers like skin when an infection invades our body than skin firstly protect our body, the second being non-specific immune cells like macrophages and dendritic cells if the skin is not enough for stop microbe then macrophages and dendritic cells help our body to protect from infection, and the third line of defence is the specific immune system made of lymphocytes like B- and T-cells, which are activated mostly by dendritic cells when they not sufficient to stop the infection. When antigen or infection enter the third line of defence than a reaction takes place between antigen and antibodies that are known as Antigen-Antibody reaction.

Disease due to Immune system

All of us any time in life suffer from fever you may surprise to know it is actually good for our body actually, it is an antibody destroying foreign antigen which enter our body by increasing body temperature. There are two aspects of the Immune system due to disease occur in our body.

Due to overactivity of immune:- When our body's antibody is responding against our own cell or organ is cause disease. Overactivity of the immune system can take many forms, including:

allergic diseases - where the immune system makes an overly strong response to allergens. Allergic diseases are very common. They include allergies to foods, medications or stinging insects, anaphylaxis (life-threatening allergy), hay fever (allergic rhinitis), sinus disease, asthma, hives (urticaria), dermatitis and eczema.

autoimmune diseases - where the immune system mounts a response against normal components of the body. Autoimmune diseases range from common to rare. They include multiple sclerosis, autoimmune thyroid disease, type 1 diabetes, systemic lupus erythematosus, rheumatoid arthritis and systemic vasculitis.

Due to lack of immune capacity:- When an antigen enters the third line of defence and attack on our antibody and our antibody is not sufficient or enough to fight and destroy the antigen then also disease occur. Underactivity of the immune system, also called immunodeficiency, can:

Be inherited - examples of these conditions include primary immunodeficiency diseases such as common variable immunodeficiency (CVID), x-linked severe combined immunodeficiency (SCID) and complement deficiencies

Arise as a result of medical treatment - this can occur due to medications such as corticosteroids or chemotherapy

Be caused by another disease - such as HIV / AIDS or certain types of cancer.

An underactive immune system does not function correctly and makes people vulnerable to infections. It can be life-threatening in severe cases.

How to Increase immune capacity

Following are the ways through which you can increase your immunity:-

Inadequate sleep may increase your risk of getting sick. Most adults should get at least 7 hours of sleep per night.
Several whole plant foods contain antioxidants, fibre, and vitamin C, all of which may lower your susceptibility to illness.
Healthy fats like olive oil and omega-3s are highly anti-inflammatory. Since chronic inflammation can suppress your immune system, these facts may naturally combat illnesses.
Gut health and immunity are deeply interconnected. Fermented foods and probiotics may bolster your immune system by helping it identify and target harmful pathogens.
Added sugars contribute significantly to obesity, type 2 diabetes, and heart disease, all of which can suppress your immune system. Lowering your sugar intake may decrease inflammation and your risk of these conditions.
Moderate exercise can reduce inflammation and promote the healthy turnover of immune cells. Jogging, biking, walking, swimming, and hiking are great options.
Given that dehydration can make you more susceptible to illness, be sure you’re drinking plenty of water each day.
Lowering your stress levels through meditation, yoga, exercise, and other practices can help keep your immune system functioning properly.
However, some studies indicate that the following supplements may strengthen your body’s general immune response:

Vitamin C
Vitamine D
Zinc
Elderberry
Garlic

An important noteNo supplement, diet, or lifestyle modification - aside from physical distancing, also known as social distancing, and practising proper hygiene ⁠— can protect you from developing COVID-19.
The strategies outlined above may boost your immune health, but they don’t protect specifically against COVID-19.
