Salt is a mineral composition of sodium chloride which is widely used for seasoning food items, preserving food, and in cosmetic and therapy industries.

But, did you know that salt has immune-boosting benefits as well? In fact, sodium chloride has been used for centuries to ward off infections and illnesses. In this article, we will outline how salt can help boost your immune system and fend off germs.

The Benefits of Salt

Salt is composed of two essential minerals – sodium and chloride and both play key roles in your body. Sodium helps balance fluid levels in your body, and chloride works with potassium, another essential mineral, to maintain electrolyte balance.

Beyond these basic roles, salt ingestion has a long history of use in medical, religious and cultural practices. For example, in ancient times, salt was valued in religious ceremonies, and used as a currency.

In modern times, salt is not only used to enhance the taste of food but also has antiseptic and antimicrobial properties.

Salt has been used in wound care for centuries, and it is still used as an effective home remedy for minor injuries and sore throats. When applied topically or mixed with water, salt creates a barrier against harmful bacteria, viruses, and fungi that may cause infections.

The Immune System and Salt

The human immune system is responsible for protecting the body against harmful pathogens. It consists of a complex network of cells, tissues, and organs that work together to defend the body.

One vital aspect of the immune system is its ability to respond to infection and illness.

Studies have shown that salt can have favorable effects on the immune system. For example, in a 2011 study, researchers found that salt enhanced the function of white blood cells, which play a critical role in fighting against infections.

Similarly, another study showed that salt intake resulted in a rise in the levels of cytokines, cellular messaging molecules that play a vital role in the immune response process.

Salt has also been shown to have a direct impact on the activity of T-cells, white blood cells that protect the body against infections by recognizing and killing infected cells.

In laboratory studies, sodium chloride has been found to increase the proliferation and activity of T-cells in mice.

Salt and Respiratory Infections

Respiratory infections such as cold and flu are common health issues that affect millions of people worldwide. These illnesses are caused by viruses that can affect the respiratory tract, making it challenging to breathe.

Studies have shown that salt can help prevent respiratory infections. In one study, patients who inhaled a sodium chloride solution experienced a significant improvement in their breathing and a decrease in symptoms of nasal congestion.

The study found that nasal saline rinses more effectively eliminated cold symptoms compared to antihistamine and decongestant treatments in both adults and children.

Furthermore, salt has been shown to be effective against viral respiratory infections. In one laboratory study, a solution of sodium chloride effectively killed influenza A virus in both human and animal cells.

Additionally, salt has been found to improve the production of mucus in the respiratory tract, which helps to lubricate and protect nasal passages and airways.

How to Use Salt to Boost Immune System

To reap the immune-boosting benefits of salt, try incorporating more salt into your diet by adding it to your meals or using a salt supplement.

However, it is essential to remember that getting too much salt can be harmful to your health, and it’s best to consult your doctor before taking any supplements or making major dietary changes.

Another way to use salt for immune-boosting purposes is to try salt therapy. Salt therapy (also known as halotherapy) is an alternative wellness therapy that involves exposing the body to a salt-infused environment.

This therapy has been shown to help fight against respiratory infections such as cold and flu, and also has anti-inflammatory properties that help to reduce inflammation in the body.

The Side Effects of Too Much Salt

Although salt has immune-boosting benefits, it’s crucial to maintain a healthy balance and avoid excess salt consumption.

Too much salt can be harmful to your body and can lead to high blood pressure, fluid retention, and other health complications.

The daily recommended intake of sodium is 2,300 milligrams (mg) for adults. However, most Americans consume over double that amount, with estimates averaging at over 4,000 mg daily.

If you consume excessive amounts of sodium, you may experience adverse health effects such as:.

High blood pressure
Fluid retention
Heart disease
Kidney damage

Conclusion

Salt has been used for centuries to ward off infections and illnesses. In recent years, studies have shown the immune-boosting effects of salt, making it a valuable tool in our fight against germs.

Salt has been found to help improve the function of white blood cells, increase the activity of T-cells, and fight against respiratory infections. However, it’s essential to remember that too much salt can be harmful to your body, and it’s best to consult your doctor before taking any supplements or making significant dietary changes.
