The immune system protects against viruses and diseases and produces antibodies to kill pathogens. This review presents a brief overview of the immune system regarding its protection of the human body from COVID-19; illustrates the process of the immune system, how it works, and its mechanism to fight virus; and presents information on the most recent COVID-19 treatments and experimental data. Various types of potential challenges for the immunes system are also discussed. At the end of the article, foods to consume and avoid are suggested, and physical exercise is encouraged. This article can be used worldwide as a state of the art in this critical moment for promising alternative solutions related to surviving the coronavirus.

Devised by wellness guru Alfredo Bataller, the immensely successful SHA method is based on a holistic approach to wellness that combines the latest advances in Western medicine and progressive natural therapies, with a particular focus on healthy, balanced nutrition and exercise.

Since reopening in July, SHA has introduced a series of new services specially designed for the COVID-19 era. Immunotherapy and lymphocyte profile consultations have been added to all bookings to assess the state of the guest’s immune system, while a new immune system strengthening pack has also been developed. A comprehensive “SHA insurance” covers medical and related expenses in the event of positive COVID-19 test on arrival.

How can we strengthen our immunity naturally?

For its normal functioning, there should be harmony and balance between the various components of the immune system. To make that happen, you can make certain lifestyle changes that will enhance your immunity and your general wellbeing. We’ve outlined few of these lifestyle changes for you below:

How to Boost Immune System During COVID 19

Be physically active – The cells of the immune system can carry out their functions effectively if there is efficient blood circulation. Exercising boosts blood circulation and in turn, the immune system. Indulging in physical activities can enhance your cardiovascular health, help you manage weight, lower your blood pressure, and lower your risk of diseases. Staying physically fit can also be beneficial for your mental health and help you cope with stress, anxiety, depression, etc. Stress is known to impair normal immune system function.
Eat a balanced diet – Appropriate and adequate nutrition is needed for all cells in the human body, including the immune system, to function optimally. Eating a balanced diet, which is one that contains the right amount of nutrients like vitamins, minerals, dietary fibre, protein, and antioxidants, can go a long way in strengthening the immune system. You can include fresh fruits, vegetables, nuts, legumes, whole grains, and lean proteins in your diet to get the nutrition you need to keep your immune system healthy.
Get enough sleep – There is evidence of sleep being one of the factors affecting the immune system response. Not getting enough sleep can reduce the circulation of white blood cells and lower the activity of the immune system. On the other hand, adequate sleep can elevate the memory of the immune system to previously encountered pathogens.
Do not smoke – Research has revealed that smoking can decrease your immune function thereby increasing your risk to infections. Besides harmful ingredients like tobacco, there are thousands of free radicals that are released per puff when you smoke a cigarette. As a result, the antioxidant level in smokers is reduced thereby causing cellular damage. Research also indicates that smoking increases the risk of severe illness due to COVID-19.
Get some sunlight – According to researchers, sunlight plays an important role in immunity by energizing T-cells which are responsible for fighting infections. The blue light emitted by the sun can speed the movement of T-cells to the infection site and initiate a quicker response. You can also get your dose of Vitamin D, which plays a crucial role in the functioning of the immune system, from the sun. However, you should avoid direct exposure to the UV rays as it can decrease immune responses and increase the risk of skin cancer.

Choose seasonal fruit and vegetables

A balanced diet that includes plenty of fruit and vegetables, vitamin C and antioxidants helps reinforce the immune system and prevent disease. It’s highly recommended to choose fruit and vegetables that are in season to ensure that they are as fresh and nutritious as possible.

Enjoy immune-boosting superfoods

How to Boost Immune System During COVID

To keep the immune system in perfect working order, we should enjoy a diet based on fresh food that helps to maintain the balance of the intestinal microbiota. It should include whole grains, beans, seaweed (spirulina), nuts, seeds, green leafy vegetables, such as kale, onions, garlic, leeks and asparagus, and fruit, such as apples.

Take moderate exercise

Moderate exercise, such as 30 minutes of fast-paced walking, has been shown to improve the function of the immune system. This type of exercise strengthens our respiratory capacity, mobilizing antibodies and white blood cells to circulate more quickly, and detect and neutralize external attacks. Meanwhile, raising the body temperature helps to prevent the development of infection.

Use deep breathing to stimulate lymph flow

Stable mental health is basic to managing stress, which, in turn, impacts the immune system. Lymphocytes are found in lymph nodes and organs, and in the blood. Lymph nodes are the body’s first line of defense against disease. Breathing is directly related to lymph flow, and lymph flow is directly related to immunity.

The diaphragm muscle, located between the lungs and the abdomen moves down when we inhale and up when we exhale. This movement causes a series of pressure differences that generate movement in the body. Lymph flow, or the mechanism that transports the lymph containing our infection-fighting white blood cells throughout the body, is one of the most crucial movements supported by deep breathing.

Get enough rest

Getting quality sleep is essential to reinforcing our immune system, while not getting enough sleep can cause our immunity to decline, making us more prone to infectious diseases. Adults should sleep at least seven to eight hours a day.

Can Supplements Help Fight COVID-19?

Supplements can help you address nutrient insufficiencies or deficiencies in your diet—but can they help you fight COVID-19? While there hasn’t been specifically-targeted research to determine which—if any—nutrients should be FDA-approved to ward off the virus, supplements are an ideal way to keep your body and your immune system functioning at optimal levels. As a result, many physicians and other health and wellness experts recommend beginning a simple supplement routine to ensure your body has the nutrients it needs to stay healthy.

While COVID-19 shares some traits with other viruses, such as previous coronaviruses like SARS and other respiratory infections like influenza, it does not behave in the same ways as those viruses. Still, it is possible to take cues from flu prevention routines and the precautions we take during cold seasons when determining which supplements might be helpful to strengthen the immune system against this new virus. Just keep in mind that very few have been studied in conjunction with COVID-19.
