AirAllergy launches its new mobile app! Follow pollen levels in real time, consult daily readings and RMI forecast maps for the coming days.
The grass pollen (Poaceae) season is now well underway, with a marked increase in airborne pollen concentrations. The critical threshold of 50 grains/m³ will be regularly exceeded in the coming weeks, as long as weather conditions remain favourable for pollen dispersal. People allergic to grass pollen may experience symptoms and are advised to follow their treatment and take the necessary precautions to limit their exposure.
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.
