It has almost been a year since we are going through the COVID-19 pandemic. We all have faced a falling economy, empty workspace, public spaces, and unbearable stress during this pandemic, and a new threat of virus mutation has worsened it all. However, the word “immunity” is like a ray of hope in our cloudy life. We all wonder how India a densely populated country is still managing to keep the infection and mortality rate low. in this article, we discuss how to increase immunity by having natural raw food and ways to boost it.


The recovery rate among Indians is above 95%, for which three factors are being considered. First, the widespread immunity in the Indian population, second, food and environmental habits (for e.g., turmeric used as a food ingredient), and third high genetic diversity particularly, HLA genotype.


We know we cannot change genetics as per our needs, but there are ways from which we can improve our immunity!

How to increase immunity

Our immune system

We have an immune system that is spread throughout the body and consists of various types of cells, tissue, organs, proteins, and secretions. Our immune system is organized in such a way that it can identify what is self (body) from non-self (foreign). Apart from keeping us safe from foreign pathogens it also regularly clears the nonfunctional or dead tissues and keeps our body healthy and updated.

Here are some ways to increase your immune system naturally and easily!


The first and most important step is to select a healthy lifestyle. Following good day-to-day habits can offer you a near-perfect immune system. Although there are various methods for boosting immunity, eating, and sleeping healthy remains the two most important factors.

1. Say no to tobacco and alcohol

Tobacco and alcohol are very harmful to our bodies. Almost all the common diseases can be linked with their abuse. However, a small amount of wine can be beneficial for the brain and heart.

2. Make exercise a daily routine

Regular exercise improves overall bodily function, improves cardiovascular health, controls blood pressure and body weight, and gives us protection against a variety of diseases. It does all that by significantly improving the flow of oxygenated blood across the body.

3. Get enough sleep

Insufficient or poor-quality sleep not only makes our body more prone to illnesses but, also affects our mental health.  Our body has a natural clock, a wrong timed sleep or an inadequate sleep may hamper the body’s capability to heal itself. Minimum 6-7 hours of sleep has been recommended adequate for adults however children might need up to 10 hours of per day sleep.

4. Destress your mind

Stress! this word is subjective which means what can be stressful to you, may not necessarily be to the other person. We can neither measure the amount of stress nor its effects on individuals. Our minds and body are closely linked. There are pieces of evidence of stress leading to stomach and GIT upset, heart diseases, diabetes, and various mental illnesses. There are studies being carried out on the link between stress and the immune system.

5. Eat healthy, with plenty of fruits and vegetables preferably in raw form

Markets are full of products that claim to enhance immunity, but should we rely on them? in fact, no one knows what type of cell line in our immune system do they act upon!


With advancing age our body becomes prone to get more infections, scientists believe that it happens due to a fall in the number of certain immune cells (T cells). However, the possibility of other factors (e.g.; nutrition) playing role in it cannot be ruled out.


Older people tend to eat less in both amount and variety, which results in a form of malnutrition known as “micronutrient malnutrition” in which the body becomes deficient in some essential vitamins and minerals that can be provided through diet.


The most commonly attributed nutrients are zinc, selenium, iron, copper, folic acid, vitamin A, B6, C & E.
