- A few minutes after contact with the allergen, sneezing stimulus develops, within a few minutes secretion, parallel to which swelling of the nasal mucosa occurs with maximum intensity after 30 minutes. At the same time, itching and impairment of the sense of smell and taste occur.
- Optional: conjunctivitis with itching and redness of the eyes and development of bronchial asthma. Occurrence in spring in case of allergy to tree pollen ( birch, alder, hazel) depending on the sensitization spectrum. Symptoms in spring/summer are sensitisation to grass pollen and cereal pollen. Sensitization to herbal pollen (mugwort, nettle, plantain) leads to symptoms in late summer to autumn.
- The symptoms are manifold:
- Pollen rhinitis: allergic rhinitis.
- Pollen conjunctivitis: allergic conjunctivitis, strong conjunctival injection.
- Pharyngitis: scratching sensation, possibly petechial haemorrhages.
- Pollen vulvitis: itching and inflammation of the vulva after contact with pollen in the vulva area in infants.
- Enteritis, tracheobronchitis, allergic pollen asthma, sinusitis, sinubronchitis.
- Pollen dermatitis: S.u. Atopic eczema.

- Pollen rhinoconjunctivitis: S.u. Rhinoconjunctivitis allergica (see also rhinitis allergica).
- Pollen dermatitis: S.u. atopic eczema.
- Pollen vulvitis: S.u. genital eczema.
- Pharyngitis, enteritis, tracheobronchitis, allergic pollen asthma, sinusitis, sinus bronchitis: avoidance of the triggering allergen, treatment by the respective discipline.

Diet/life habitsThis section has been translated automatically.
- Testing of the allergy with clear definition of the allergens!
- Avoid sports activities and walks in meadows and fields during the flowering period of "your allergy plant"!
- Keep windows closed during the day. This also applies at night! Pollen flight starts between 3.00 and 5.00 o'clock in the morning. During this time the pollen density is at its highest!
- Wash your hair in the evening to remove the pollen that has settled in your hair during the day!
- For spectacle wearers: regular cleaning of lenses and frame!
- Do not put clothes worn during the day in the bedroom (pollen will get stuck in your clothes!)
- Daily vacuuming (if possible not by yourself) with a vacuum cleaner with pollen or fine dust filters helps to remove pollen from carpets and furniture!
- No consumption of honey, because it contains pollen!
- Close windows and turn off the ventilation when driving a car!
- Drivers of frequent cars should consider the installation of an air conditioning system with pollen filter!
- Spend your holiday in pollen-poor "clean air areas" such as high mountains and the coast!
- Pay attention to the pollen flight information (local radio stations).
Note(s)This section has been translated automatically.
It is remarkable that bacteria use pollen as an aerogenic transport system. This has been proven for mugwort pollen, which is preferably contaminated by Pseudomonas luteola. This finding is of importance for a pollinosis in so far as bacterial endotoxins have been shown to increase the inflammatory effect of pollen (Technical University Munich 2018).
