Spring in the Saaletal Challenges Hay Fever Patients
With the spring-like conditions in mid-April, the pollen count in Jena traditionally reaches one of its first major peaks of the year. Birch, in particular, whose pollen is considered highly allergenic, is currently causing significant problems for many people with hay fever. The topographical basin location of Jena can also lead to fine floral dust collecting in the valley during light winds, temporarily increasing the concentration in the air further.
In addition to birch, isolated alder and increasingly ash pollen are currently detectable in the air. Changes in weather or rain showers could provide temporary relief in the coming days by cleansing the air.
Guide: Prevention and Tips for the Pollen Season
To best alleviate symptoms in everyday life, experts recommend that allergy sufferers follow some basic rules of conduct:
- Correct ventilation: In the city, pollen concentration is usually highest in the evening. It is therefore recommended to use shock ventilation in the early morning hours between 6 and 8 a.m.
- Adjust walks: Popular local recreation areas such as the Paradiespark or the heavily vegetated slopes around the Kernberge should be avoided by sensitive individuals on dry, windy days.
- Daily hygiene: Wash your hair in the evening before going to bed and never leave clothes worn outside in the bedroom to avoid taking pollen into bed with you.
- Air purifiers: The use of HEPA filters in living spaces can noticeably reduce allergen exposure.
