When temperatures stay high after sunset, getting a good night's sleep can feel impossible—especially if you live in an older home or apartment without central air conditioning. Across the U.S., more families are searching for low-cost ways to stay comfortable while keeping electricity bills under control. One surprisingly effective trick doesn't require a new appliance or expensive gadget.
All you need is a clean bathroom towel, cool water, and a fan used under the right conditions. While this simple method won't replace air conditioning, experts say it can make your sleeping space feel more comfortable. Just as important, health officials warn that fans are not always safe during extreme heat, making it essential to know when this cooling hack works—and when it's time to find a cooler place.
Can a damp towel really make your bedroom feel cooler?
The towel trick is based on a basic scientific principle called evaporative cooling. Start by soaking a clean towel in cool water and wringing it out until it is damp but not dripping. Hang it near an open window or place it in front of a fan so air moves across the wet fabric. As the water slowly evaporates, it absorbs heat from the surrounding air, creating a cooler breeze in the immediate area.
