Salt inhalation: how to inhale correctly for asthma & COPD

Salt is now more than ever a therapeutic all-round talent: As a natural active ingredient, it is used in many forms in the treatment of a wide variety of diseases. For respiratory patients with asthma or COPD, inhaling nebulized saline solution is a popular home remedy.

This is what salt inhalation brings to asthma and COPD

The therapeutic benefits of inhaling 0.9 percent saline solution have been well documented for respiratory diseases:

On the one hand, this is beneficial anti-inflammatory and antibacterial effects of saltwhich helps to reduce the swelling of the mucous membrane and to promote blood circulation.

On the other hand, inhaling salt water causes the mucous membrane to build up more fluid in the airways. This effect is particularly beneficial for asthma and COPD patients who struggle with thick mucus in the bronchi.

Regular inhalation of salt

  • protects the mucous membrane from drying out
  • stimulates the flow of mucus
  • loosens stuck mucus
  • improves the removal of pollutants and pathogens

For many patients with asthma and COPD, inhaling salt is a suitable means of relieving their symptoms and preventing acute infections of the respiratory tract.

How does the salt get into the airways?

Basically, you have various options: You can inhale salty air during a spa stay on the North or Baltic Sea ("surf breathing") or when visiting one of the many artificially created salt caves.

However, the regular one is easier and just as effective Inhaling salt water with a nebulizer.

Inhale properly with salt - that's how it works

For inhalation with salt you need 2 things:

  1. Isotonic saline solution consists of a 0.9 percent salt solution, i.e. 9 grams of salt to 1 liter of water. You can get a sterile solution for inhalation in small, practical packets from the pharmacy or on the Internet. You can also create the solution yourself. You can find out what to look out for at
  2. Electric nebulizers are inhalers that atomize saline solution into tiny droplets. The smallest possible droplet size is crucial for the effectiveness of the inhalation - because only the smallest droplets (aerosol) reach the lungs with their widely branched bronchial system. You inhale the aerosol through a breathing mask, which is available in different sizes for adults and children.

When and how often do you inhale?

  • Inhale once or twice a day for 6 minutesto prevent acute infections.
  • In the case of heavy mucus or during an acute infection, you can inhale several times a day.
  • Breathe in the salt-containing active ingredient mist as deeply and slowly as possible.
  • If you have a productive cough, especially at night, it is best to inhale just before bed.
  • You can combine the inhalation of saline solution with the daily use of respiratory therapy devices such as the RC-CornetĀ® PLUS. This saves time and increases the effectiveness of the therapy.
