Why Put Soap Under Your Mattress? – [Complete Information]

Have you ever heard of placing soap under your mattress? It may sound peculiar at first, but this age-old practice has been touted for various benefits, from repelling bugs to promoting better sleep.

In this article, we’ll delve into the fascinating world of placing soap under your mattress and explore the science behind this unusual yet intriguing technique. Rest assured, this isn’t a mere old wives’ tale; there’s legitimate evidence to back it up.

Understanding the Concept:

Placing soap under your mattress is believed to be effective due to the presence of certain compounds in soap that can deter pests and even improve air quality. The soap’s fragrance, particularly those containing essential oils, can have a repelling effect on bugs such as bed bugs, mites, and fleas.

Additionally, certain soap ingredients, like lavender or eucalyptus, are known for their natural insect-repelling properties.

Moreover, when soap is placed under the mattress, the act of lying down on the bed can cause the soap to release its pleasant fragrance, creating a relaxing and calming atmosphere. This can potentially contribute to better sleep quality, as the soothing scent helps reduce stress and anxiety.

Keeps Away Most Kinds of Bugs

One of the primary reasons people resort to putting soap under their mattresses is to keep bugs at bay. Bed bugs, in particular, are a notorious pest that can wreak havoc on your sleep and well-being. These tiny, blood-sucking creatures are notoriously difficult to eliminate once they infest your mattress and bedding.

The fragrance of certain soaps, such as those infused with citrus or herbal scents, can act as a natural repellent for these unwanted pests. The scent interferes with their ability to detect human hosts, encouraging them to seek refuge elsewhere.

Not only can soap help fend off bed bugs, but it may also discourage other creepy crawlies like dust mites, fleas, and even ants from invading your sleeping sanctuary.

Where to Keep the Soap for Better Results?

Placing soap under your mattress can be done in a few different ways. Some people choose to wrap a bar of soap in a cloth or a small plastic bag to prevent any soap residue from seeping into the mattress. Others opt to place the unwrapped soap directly under the mattress, between the mattress and the box spring, if applicable.

For those who prefer not to place the soap under the mattress, simply keeping it in the vicinity of the bed, such as on a nearby nightstand or under the bed, can still yield some benefits. The soap’s fragrance will permeate the air around the bed, creating a bug-repellent barrier.

The Science Behind Soap Under Mattress

While the concept of placing soap under the mattress may seem unconventional, there is evidence to support its effectiveness. Several studies have shown that certain essential oils, commonly found in natural soaps, have insect-repelling properties. For instance, lavender oil has been found to repel bed bugs, mosquitoes, and other pests due to its strong scent.

Other Benefits of Placing Soap Under Mattress

Apart from bug-repelling properties, some soap types, particularly those containing natural ingredients, can contribute to better sleep quality. The calming scents released by the soap can help relax the mind and body, leading to a more restful sleep.

Additionally, certain soap compounds can help improve indoor air quality. For example, glycerin soap is known to release negative ions, which can help neutralize airborne allergens and pollutants. This can be particularly beneficial for individuals with respiratory issues or allergies.
