To understand why some people develop reactions and others do not, we must look to the immune system. In the subjects concerned, it is a dysregulation in the face of allergens due to a deficit of antibodies or T lymphocytes, responsible for immune responses.

However, not having an identified allergy does not mean that this will never be the case, since a person who is not affected, even for years, can become one in the event of excessive or prolonged exposure. So be careful not to overexpose yourself to it.

To do this, one of the best assets remains the pollen map, well known to allergy sufferers.

On the treatment side, there are drugs capable of reducing the symptoms (corticosteroids, antihistamines), but above all desensitization for certain allergies. The technique consists of injecting, over a long period, small doses of allergen to train the immune system. For some years, the treatment can also be administered by sublingual drops or tablets.
