In life, we often find that sun-dried quilts have a special smell, which is affectionately called "sun smell". There is a popular saying that the smell is actually the smell of sunburned mites. So, is the "sun smell" after drying the quilt really because the mites are scorched?
Mites are tiny creatures that are mainly found in our bedroom environment, especially mattresses, quilts, pillows, etc. Mites feed on the dander that is shed, so they are closely related to our lives. Despite the abundance of mites, they are so tiny that they are barely visible to the naked eye.
Basking in the sun is indeed an effective way to get rid of mites. Ultraviolet rays from sunlight have a bactericidal effect and are able to kill some mites on the quilt. In addition, sun exposure can also evaporate the moisture on the quilt, making the quilt drier, which is not conducive to the survival of mites.
However, the "sun smell" after drying the quilt is not because the mites are burnt. In fact, the smell of the mites being burnt is very unpleasant, quite different from what we call the "sun smell". So, where does the "sun flavor" come from?
Scientists have found that the "sun smell" after drying the quilt actually comes from the chemical reaction of the fibers, fabrics and other substances on the quilt after being exposed to the sun. When exposed to ultraviolet light, these substances undergo an oxidation reaction to produce a chemical called "nonanal". Nonanal has a subtle floral scent, which is what we call "sun scent".
Although drying a quilt does not completely eliminate mites, it still has great benefits for our health. Exposure to the sun kills some mites, reduces allergens, and reduces the risk of respiratory diseases. In addition, sun exposure also keeps the comforter dry, making us more comfortable while sleeping.
In short, the "sun smell" after drying the quilt is not because the mites are scorched, but from the chemical reaction of the fibers, fabrics and other substances on the quilt after being exposed to the sun. Although sun exposure can't completely eliminate mites, it still has great health benefits. So let's dry our quilts often and enjoy the smell of the sun.
