We are in the peak season for alder and hazel pollen. During dry weather conditions, pollen concentrations can rise rapidly. People sensitized to this pollen type should take every precaution. It is also likely that people allergic to birch pollen may have symptoms in this period, due to cross-reactivity with alder and hazel allergens.
A few useful recommendations: avoid outdoor activities, wear sun glasses, do not dry linen outside, rinse your nose regularly, wash your hair before going to sleep.
Typical allergy symptoms such as runny nose, cough or shortness of breath (in case of asthma) can easily be mistaken for a cold, flu or coronavirus infection. However, fever and body aches should be given special attention as they might be caused by viral infection. It is recommended to call your general practitioner in case of doubt.
The standardized pollen detection technique allows retrospective measurement of the levels from samples taken the day before. Samples are analyzed manually during the working days by optical microscopy.
