Halotherapy: The Science Behind Salt Therapy 

Let’s talk about the science behind halotherapy, and all of its amazing benefits. In case you missed our last blog post we are continuing to dive deep into Halotherapy. In that blog we focused on the question “ What is Halotherapy?” (interested in that topic, click here!) 

First off, halotherapy—aka salt therapy—is 100% natural, and contributes to your overall wellness. Here are some of our favorite benefits (though there are more than 30): 

  • Reduces stress and anxiety;

  • Strengthens the respiratory and immune systems;

  • Regulates sleep; 

  • Improves skin conditions; and 

  • Enhances athletic recovery and performance.

You might ask, how can halotherapy help improve immunity and respiratory health? Pharmaceutical grade salt that is dispersed into the air in a halotherapy session is a pure form of  sodium chloride (NaCl) and it is naturally anti-inflammatory, antibacterial, antiviral, and antifungal. Salt has properties which can help reduce inflammation. Salt therapy uses the salt particles to reduce inflammation in the entire respiratory tract as well as widen our air passages. Just walking on the street, we are exposed daily to pollutants, airborne diseases, bacteria, allergens, and other residual toxins. The salt absorbs foreign substances as it enters your respiratory tract, and since dry salt particles are known to accelerate the transportation of mucus, they aid in the elimination of toxins. Your body naturally gets rid of the salt thereby eliminating the foreign materials as well. It’s a natural detox of your respiratory tract!

The “job” of the lungs is to deliver oxygen to our red blood cells and remove carbon dioxide from the body, as well as act as a defense mechanism by filtering the air we breathe, regulating the pH level of blood by managing CO2 levels, and helping to control blood pressure. Therefore, we want to keep our respiratory system healthy and clean, which can result in higher oxygen intake, increased energy, and improved immunity. Dry salt therapy can positively impact people suffering from respiratory conditions like allergies, asthma, bronchitis, cystic fibrosis, COPD, and others.


In addition to the amazing respiratory benefits of Salt Therapy, halotherapy can also  improve certain skin conditions. When you’re in a halo session, salt particles land on the skin and absorb any bacterial and foreign substances. The increased activity of skin cells as they react to the salt enhances the electrophysiological activity that determines the skin’s protective properties. The salt pH balances the skin and induces both reparative and regenerative processes in our derma, as well as increases skin rigidity, stimulates cell rejuvenation, and improves hair health. The anti-inflammatory, antibacterial, antiviral, and anti-fungal properties of dry salt mentioned also help with absorbing impurities and improving acne, psoriasis, and eczema. By attending regular sessions to the salt room clients have noticed their conditions from acne to eczema have been minimized. 

What’s the difference between a Himalayan salt room, and a salt room that provides halotherapy?

A Himalayan salt room involves sitting and relaxing in a room that is meant to look like a salt cave. A salt room is a room decorated with salt. A salt room that provides halotherapy takes the wonderful relaxing properties of a salt room and adds a treatment that helps you detox and feel better. In a salt room providing halotherapy particles of pure sodium chloride are consistently dispersed at a certain concentration level over a determined period of time -  boosting your immunity and providing a natural detox to your respiratory system, while providing the benefits of relaxation and resetting.
