Importance of a Strong Immune System During COVID-19

COVID-19 has brought to the fore the importance of a robust immune system. Statistics suggest that the older population is more prone to catching the virus and succumbing to it. The younger population’s death rate is comparatively much lower; the reason is being attributed to the stronger immune system. But a healthy immune system is not only crucial during large scale pandemics; it is necessary throughout the year to fight off the other mild to severe diseases. Apart from protecting against various diseases, a healthy immune system also improves the quality of life.

Frequency of Falling Sick Among Indians During 2019

The graph below shows the percentage of Indians who fell sick at least once or twice a year, who didn’t fall even ill once and those who did more than twice a year. This is the result of an extensive survey conducted across India in 2019. Only 24 percent of the respondents stated that they have not been sick even once a year. This indicates that they have a robust immune system.

Why do you Need a Strong Immune System?

A robust immune system successfully defends the body against various diseases. While some people are born with a strong immune system that gives them a natural ability to fight off infections, others are not so fortunate. Through natural foods, supplements and workouts, the ones born with a strong immune system and others can strengthen it to keep disease causing microorganisms at bay. There are so many microorganisms attacking your body throughout the year, and then there are occasional pandemics such as the COVID-19 that overwhelm the immune system. Hence, it becomes imperative to boost the immune system and prepare your body to defend against the inevitable attack.

Causes of a Weak Immune System

There is no one factor that can cause the immune system to be strong or weak. Several reasons can cause your immune system to be either strong or weak. The following are some of the reasons that can cause the immune system to weaken, and thereby make the body more susceptible to successful attacks from pathogens:

  • Primary immune deficiency – When you are born with a weak immune system.
  • Acquired immune deficiency – When disease causes your immune system to weaken.
  • Autoimmune disease – When the immune system mistakenly attacks your body.
  • Allergic reaction – When the immune system reacts abnormally to a foreign substance and becomes too active.

Other Reasons That Cause a Weak Immune System

Stress

Several studies have shown that long-term stress weakens your body’s ability to respond to a threat efficiently.

Lack of adequate sleep

Lack of adequate sleep is known to weaken your system. Getting a proper amount of sleep not only strengthens immunity naturally but also helps to fight off infections after falling sick.

Poor diet

A poor diet is often linked to a weak immune system. Several studies have shown that malnourished people are more susceptible to diseases due to a compromised immune system.

Lack of exercise

A lack of regular exercise and the resultant sedentary lifestyle can cause the immune system to weaken.

Ageing

Old age weakens the immune system’s capability to defend against microorganisms.

Smoking

Smoking causes a lot of health issues like cancer and respiratory illnesses that could weaken your body.

Alcohol

A little bit of alcohol does not cause much damage; it could also be beneficial, but a lot of it can weaken your immune system.

Signs of a Weak Immune System

If you fall sick often and can’t figure out the reason for it, your immune system could be compromised. Watch out for these warning signs and try to boost your immune system.

Regular bouts of cold:

It is common to be afflicted by cold a couple of times a year, but if you get frequent colds that do not run their course, your immune system could be struggling to fight off the infection.

Frequent infections:

If you suffer from recurring infections throughout the year, like sinusitis, allergies, pneumonia and other ailments, this could be an indication of a weak immune system.

People with a weak immune system may also experience digestive issues and autoimmune disorders.

How to Improve your Immune System

Your body is capable of defending itself against a host of disease-causing microorganisms. Still, its defence capabilities are not impenetrable, and germs often find a chink in the armour which causes you to fall sick. Many are born with a weak immune system, and then there are many factors that can cause the immune system to weaken over time. But, there is no one solution to strengthen your immune system; it is the sum of several factors that leads to a robust immune system. So, there are several ways to improve the immune system. First, it is essential to get rid of certain habits that weaken the immune system. The next step is to provide the body with proper nutrition through natural foods, regular exercise and even supplements.

Get Adequate Sleep

A lack of proper sleep is known to cause your immune system to weaken. Good quality sleep provides the body with much-needed rest and improves its ability to defend against a host of disease-causing microorganisms. Multiple studies have suggested that adequate sleep strengthens the immune system. But how much sleep does one need? It differs according to the individual’s age. Younger children and infants need more than 10 hours of sleep while young adults and older people need around 7-9 hours of sleep with a minimum of 6 hours. Although different studies suggest different numbers, there is no doubt that an adequate amount of quality sleep rejuvenates the mind and the body, and is necessary to stay healthy and improve the immune system.

Maintain Social Distancing

While COVID-19 may have popularised the idea of social distancing, which is now ingrained in society’s consciousness, it is a practice that should be followed, even when the coronavirus has ceased to wreak havoc on the world. Everyone, regardless of their immune systems’ capability in defending against pathogens, must maintain social distancing from sick people suffering from contagious diseases. A person with a weak immune system can easily catch a disease from a sick individual; even a healthy person can catch an infection from others. So it is wise to keep a safe distance if you perceive someone to be suffering from a disease. Wearing a mask and sanitizing your hands and surfaces that you come in contact with also helps avoid being infected by another person.

Quit Smoking

Several diseases are caused by smoking, including cancer, flu, pneumonia, and other respiratory illnesses. It can cause your immune system to weaken and your body’s ability to fight diseases. Smoking is an addiction, and it can be challenging to kick the habit. So, you have to use certain aids to help you fight the addiction, like nicotine gums and patches. You could also consult a doctor to help you get rid of this habit and improve your immune system.

Lower the Stress Levels

Stress is the root cause of several diseases. Long term stress compromises your immune system’s abilities. Stress can lead to the worsening of several conditions like obesity and heart disease. You can reduce stress by engaging in activities that relieve stress, such as – exercising, socializing, meditating and doing anything that makes you feel happy and at peace. Many experts believe stress to be the reason for many physical and psychological diseases, so reducing stress can help you strengthen your immune system and result in you achieving optimal health.

Maintain Hygiene

The simple act of keeping your surroundings and your hands clean could go a long way in avoiding diseases. Washing your hands before eating and after touching any dirty surface keeps the germs away. Germs lurk around every nook and corner of your house, office and public places. Every surface such as the kitchen platform, keyboard, phone, remote control and others around you are teeming with germs. But, there are also many who say that extreme hygiene can make our immune system more vulnerable to germs that wouldn’t threaten it otherwise.

Control Weight

Obesity can cause several diseases including cardiovascular disease, diabetes, high blood pressure and high cholesterol. It can also cause the immune system to weaken and thereby increase the risk of falling sick. Often obese people indulge in unhealthy eating, devoid of proper nutrition. Hence, it is essential to maintain a healthy diet and keep weight in check.

Foods to Boost the Immune System

Many products in the market claim to strengthen the immune system, but the best and the healthiest way to do that is naturally. There are many naturally found food that are reservoirs of healthy nutrients that help boost your immune system. A diet rich in colourful foods full of fruits, vegetables, nuts, dry fruits, whole grains, herbs, spices, tea, and seafood can boost the immune system. Citrus fruits, almonds, garlic, ginger, spinach, turmeric and green tea are some of the foods that can improve your immune system’s strength. Consuming these foods helps to give your immunity a boost and keeps other diseases at bay. And, this is the best way to increase your immune system’s capability without suffering any side effects. Studies also show a direct relation between malnourishment or low nutritional intake and a weak immune system. Hence, this reinforces the belief that the best and safest way to increase your immune system is through natural foods.
