Freshly washed laundry often smells pleasant outdoors and dries quickly in the sun. For people with pollen allergies, however, this can bring irritants into the home: damp fabric absorbs pollen especially well. The Austrian health portal therefore recommends that affected people dry laundry indoors as much as possible during the pollen season relevant to them.
In August the exposure changes. The main grass season ends in many places, while mugwort and, depending on the region, ragweed begin. What matters is not only the month but the individual's allergy and the current regional forecast. Someone who reacts to birch does not automatically react to ragweed, and vice versa.
A brief decision aid
| Situation | Suitable drying location | Additional step |
|---|---|---|
| No pollen allergy in the household | Outside or inside, depending on the weather | Protect laundry from rain and dirt |
| Known allergy, currently low exposure | Preferentially dry sensitive textiles indoors | Check the regional pollen forecast |
| Medium or high exposure from the individual's trigger | Indoors | Avoid using the bedroom as a drying room |
| Bedding, cushion covers or clothing with direct contact with the face | If allergic, preferably indoors | Store clean and closed until use |
Why damp laundry picks up pollen
Pollen float in the air, are transported by the wind, and settle on surfaces. They adhere more easily to damp fibers than to dry ones. If a sheet is then put on the bed or a T-shirt is worn, the allergens come very close to the nose, eyes and skin. Outdoor drying is therefore particularly unfavorable for bedding, towels and clothing that are in the bedroom at night.
A sunny day is not automatically a good day for a clothesline. Dry, warm and windy conditions can promote pollen dispersal. Rain can temporarily reduce the pollen load, but blanket rules about time of day are unreliable. Use the current forecast from the Austrian Pollen Information Service and select your federal state. Only the plant species that the affected person actually reacts to is relevant.
How to dry laundry indoors without moisture buildup
- Spin well: A higher spin speed appropriate for the fabric shortens the drying time. Follow the care label.
- Hang with space between items: Thick items should not be folded double over the line. Shirts, pants and towels need air between the fabric layers.
- Choose an appropriate room: A well-ventilated room is better than a bedroom or a windowless bathroom. The drying rack should not be placed directly against a cold exterior wall.
- Vent out moisture: Ventilate several times briefly and vigorously when the outdoor air matches the personal pollen situation. A hygrometer shows whether the indoor humidity remains persistently high.
- Circulate the air: A fan can support drying. It should not just push the moist air against a wall, but improve air circulation in the room.
If towels remain damp for a long time or the room smells musty, the drying is too slow. More spacing, a different room or an additional spin cycle can help. Further practical details are available in the guide Laundry doesn't dry in humidity: How to keep it fresh.
If the laundry was hung outside after all
Low pollen levels, limited space in the apartment, or large items of laundry can lead to drying outside. In that case, put the laundry directly into the wardrobe or laundry basket and do not shake it out vigorously in the bedroom or living room. The health portal cites ironing as an additional step when laundry has been dried outdoors. However, it is no substitute for taking personal pollen exposure into account.
- If symptoms are pronounced, rather rewash bedding and cushion covers and dry them indoors.
- Do not place clothing worn outdoors on the bed, sofa or bedroom chair.
- Wipe clothespins and lines regularly with a damp cloth if they remain outside all year.
- Keep the empty basket clean so that fresh laundry does not come into contact with pollen and dust from the last use.
Does pollen-contaminated clothing need a special detergent?
A special allergy detergent is generally not necessary to remove pollen. The decisive factor is actually washing the clothing, not just shaking it out or airing it in the living area. Choose the program and temperature according to the care label and the level of soiling. Using more detergent than the manufacturer recommends for water hardness and load does not automatically improve the result and can leave residues in the fibers.
Collect heavily contaminated daytime clothing, if possible, in the entryway or in a closed laundry container outside the bedroom. Wash your hands after putting the item away. Jackets or delicate textiles that cannot go in the machine after every wear should also stay outside the sleeping area. With persistent symptoms, the deciding factor is not the hottest possible program but the combination of regular washing, an appropriate drying place, and a current pollen forecast.
Do not carry pollen into the bedroom via clothing
Drying is only part of the daily routine. The health portal also advises not to leave shoes and clothing worn outdoors in the living area or bedroom. Jackets and daytime clothing should have a fixed place in the entryway. Washing your face and hair before going to bed can prevent pollen from being distributed on the pillow. Surfaces are better wiped damp than dusted dry.
Anyone who discovers ragweed in their own garden should not handle the plant unprotected and during flowering next to laundry. How it is identified, removed and disposed of is explained in the article Recognize and remove ragweed.
FAQ
Can you safely dry outside after a rain shower?
Not generally. Rain can wash pollen out of the air, but the exposure depends on the plant species, region, wind and further weather development. Check the current forecast.
Is it enough to shake out laundry dried outdoors?
No. Shaking does not reliably remove pollen and can distribute it in the apartment. For known allergies, drying indoors is the more reliable solution.
Does the whole family have to dry indoors?
That is a household decision. It makes particular sense for the affected person's textiles as well as for shared bedding and towels.
When should an allergy be medically evaluated?
Recurrent seasonal rhinitis, itchy eyes, coughing or breathing difficulties should be medically evaluated. In the case of acute shortness of breath, the emergency number in Austria is 144.
