Do you often suffer from a build-up of phlegm, coughing and/or a tickly throat as a result of a lung condition?

Halotherapy or salt therapy is a 100% natural, safe treatment method for all kinds of respiratory conditions that cause breathing problems. While not curative, it may help alleviate symptoms by up to 85%.
Salt has antibacterial properties. Every surface of the salt room is covered in salt, with medicinal salt also being dispersed in the room during the halotherapy session. These salt particles are so tiny that they are inhaled into the deepest layers of the lungs. This reduces inflammation and thins phlegm, cleansing the lungs in the process. So, halotherapy may be an effective therapy for people who suffer from chronic colds, asthma, hay fever, smoker’s cough etc.
And, because of its potential beneficial effect on lung function, halotherapy may also be a very suitable supporting treatment for top athletes who want to boost their performance.
Did you know that at Thermae Grimbergen, we organise two different halotherapy sessions every day which our guests can take part in free of charge? You do need to sign up at the centre because spaces are limited. Also, please turn up five minutes before the start of your halotherapy session outside the salt room wearing a bathrobe.
Do you suffer from a serious lung condition? Make sure to consult your GP first.
