This simple trick will cool down your home in summer
Share
When temperatures rise in summer, it doesn't just get unpleasantly warm outside – many apartments also heat up noticeably. Air conditioning units aren't always an option, and a fan often just circulates the already warm air. A simple approach that many already have at home is damp laundry on a drying rack.
Sounds unusual at first – but it's based on a clear physical effect.
Why damp laundry can make the air feel "cooler"
When water evaporates, it draws heat from its surroundings. This effect is known as evaporative cooling. As a result, the air can feel subjectively fresher – even if the room temperature only drops slightly or not measurably at all.
Important: This is not an air conditioner and does not replace active cooling. However, it can be perceived as a small relief during heatwaves – especially if the air isn't completely still.
How to use this trick correctly
- Take freshly washed laundry or dampen light textiles (e.g., T-shirts, thin towels).
- Hang them loosely on a drying rack (not too close together, so air can circulate between them).
- Place the rack where you spend most of your time, if possible.
- Ensure some air exchange (e.g., brief blast ventilation or a window slightly ajar, depending on the weather).
The better the air flows past the laundry, the faster the moisture evaporates – and the sooner the effect will be noticeable.
Why air circulation is crucial
Without air movement, humid air remains "stagnant," evaporation slows down, and the effect is less pronounced. At the same time, in very small, poorly ventilated rooms, humidity can rise significantly. Therefore, it's best to use it moderately and ventilate regularly.
Supportive: even air circulation under the drying rack
If you dry laundry indoors, a consistent airflow is often more helpful than just "anywhere" a fan. HEYDRY is designed as a drying rack alternative for gentle drying and creates an airflow under the drying rack that carries humid air upwards and supports evaporation.
Note for classification: HEYDRY is not a cooling device. A possible "cooler room feeling" effect only arises indirectly through accelerated evaporation and air movement.
Tip: If you're drying laundry indoors anyway, targeted air circulation can help moisture leave the laundry faster – without heat. This can make everyday life more pleasant in summer.

Does damp laundry really lower the room temperature?
Usually, the measurable temperature only drops minimally or not at all. However, many find the air to be fresher because evaporation draws heat from the environment (evaporative cooling).
Can too much damp laundry increase humidity too much?
Yes, especially in small rooms without air exchange, humidity can rise significantly. Therefore: don't overdo it and ventilate regularly.
How can I best enhance the effect?
Air movement is crucial: more airflow past the laundry means faster evaporation. Also, make sure not to hang the laundry too close together.
Is HEYDRY an air conditioner or a fan?
No. HEYDRY is designed for drying laundry on a drying rack. A "cooler room feeling" can only arise indirectly through evaporation and air movement.
Conclusion
Damp laundry can be a small home remedy trick in summer to make the air feel subjectively a little more pleasant. It works best with sufficient air circulation and regular ventilation – then the effect remains controlled and practical for everyday use.
