Can mold cause a stuffy nose, itchy or watery eyes, and sore throat?

Itchy eyes ,nose and throat and watery eyesMold poison symptoms


Everyone in their life may experience a runny nose and itchy or watery eyes as it is a natural response of the body resulting from the release of a chemical known as histamine.

As a component of the immune system, this substance helps expel viral pollutants.


Symptoms such as itchy or watery eyes, runny or clogged nose, and sore throat can result from:

1)Mould: A type of fungus that may live indoors or outdoors and develop in hot, humid environments.

Like any allergy, the symptoms of a mold allergy are caused by a too sensitive immune system response. When you inhale small spores of airborne mold, your body recognizes them as foreign invaders and develops allergenic antibodies to fight them. After the end of the exposure, you always produce antibodies that “remember” the invader so that any future contact with the mold triggers your immune system to react. This reaction triggers the release of histamine, which causes itching, runny eyes, runny nose, sneezing, throat itching, and dry, cracked skin.

2) allergic rhinitis: inflammation of the interior of the nose caused by an allergen, such as pollen, dust, mold, or skin flakes of certain animals.

An allergen is a harmless substance that provokes an allergic reaction such as allergic rhinitis which can lead to a Runny nose, Itchy nose, Sore throat, itchy eyes, or Watery eyes, and Eczema-type symptoms, such as severe dry skin


Good allergy treatment is based on good medications.

  • Nasal corticosteroids like ciclesonide (Omnaris, Zetonna), mometasone (Nasonex), and budesonide (Rhinocort).
  • OTC antihistamines include loratadine (Alavert, Claritin), fexofenadine (Allegra), desloratadine (Clarinex), cetirizine (Zyrtec).
  • OTC oral decongestant: Pseudoephedrine (Sudafed) and Drixoral.
  • Decongestant nasal vaporizers: oxymetazoline (Afrin).
  • Immunotherapy: a series of allergy vaccines that are very effective for certain types of allergies, like hay fever.


The best way to prevent allergy symptoms is to take action to prevent exposure to its triggers.

To avoid allergic rhinitis :

  • Start taking medication before seasonal allergic episodes. For example, if you have a spring allergy to tree pollen,  start taking antihistamines before an allergic reaction occurs.
  • Make sure your home is not a friendly environment for developing dust mites. If you have carpets, use a HEPA vacuum cleaner. Also, wash bedding weekly with hot water to reduce exposure to mites during your sleep.
  • restrict exposure to all animals to which you are allergic. If not possible, make sure you wash your hands immediately after touching the pets and keep your furry friends away from your bed.

To minimize your exposure to mold spores, outdoors and indoors:

  • Limit your outdoor activities when the number of molds is high so that you do not inhale large amounts of mold spores.
  • Use the central air conditioner with certified asthma and allergy filters.
  • Lower your home’s humidity to less than  35%.
  • Pay close attention to mold in washrooms and basements.
  • Quickly repair all plumbing leaks.


 Stuffy nose, itchy or watery eyes, and sore throat are all common symptoms of allergy. This may include allergy to pollen, dust, pets, or mold.

 If those symptoms showed up on you, you must first know the underlying cause then receive the appropriate treatment, but most importantly, remember that prevention is always better than treatment.
