Rhinopharyngitis, more commonly called a cold, is the most common infectious disease:

  • Children are the most affected: they can catch colds up to 12 times per year*.
  • Adults catch 2 to 3 colds per year on average**.
  • They are caused by a reaction of our immune system to the germs and viruses present in our environment.

Cold symptoms:kind krank

  • Nasal discharge
  • Nasal congestion
  • Sore throat
  • Sneezing
  • High temperature

Colds weaken the nasal mucosa, and left untreated, they may deteriorate into:

  • Otitis, especially in children
  • Sinusitis
  • Pharyngitis
  • Bronchitis
  • Pneumonia
  • Bacterial cross-infection: thick nasal discharge and symptoms lasting several weeks

Using isotonic spray like HUMER Daily Hygiene or hypertonic spray like HUMER Blocked Nose 100 % seawater during colds minimises these risks by:

  • Cleaning the nose
  • Removing mucosities.
