Hanging laundry outside between 12pm and 4pm can significantly reduce pollen exposure and improve sleep quality for hay fever sufferers, according to experts from Allure Bath Fashions. The '12pm rule' advises drying clothes during this window to avoid trapping peak morning pollen in damp fabrics.
Why Timing Matters
Pollen counts typically peak early in the morning and decline around midday as rising temperatures disperse particles higher into the atmosphere. The warmer midday sun also dries out pollen grains, allowing wind to carry them away from laundry. Bringing clothes in before 4pm is crucial because cooling evening air causes pollen to settle back to ground level.
Practical Steps to Reduce Pollen
All garments should be thoroughly shaken before bringing them inside to dislodge any settled pollen. Drying racks should be placed on paved patios away from grass or trees, and clothes should never be left outside overnight. These steps help prevent streaming eyes, itching, and coughing that can disrupt sleep.
Expert Recommendation
Katherine McPhillips and Gary Stewart, writing for the Liverpool Echo, urge families to adopt the 12pm rule this summer. The advice comes as July coincides with peak grass pollen levels, making air-drying laundry a potential health risk without proper timing.
