【い草の知られざる効果効能】ただの「敷物」じゃない、暮らしを変える天然素材

"Igusa" is used for tatami mats and tatami mats.
 It somehow has a strong Japanese image and is often chosen for its design and appearance, but in fact, igusa has more incredible functions hidden within it than meets the eye .

In this article, we will introduce the lesser known effects and benefits of rush grass, including the scientific evidence to back it up .

■ 1. Deodorizing effect | Igusa grass absorbs odors in the air.

The surface of the rush grass has countless tiny pores (holes), which have the ability to absorb and neutralize ammonia, cigarette smoke, and other household odors in the air .

In fact, a study previously published by the Ministry of Agriculture, Forestry and Fisheries reported that rush grass is effective at absorbing more than 70% of ammonia gas .

Examples of odors that are said to be particularly effective:

  • Pet urine odor and body odor

  • Oily and garbage smells in the kitchen

  • Shoe odors and odors around shoe cupboards

One of the unique strengths of rush grass is that it can reduce the risk of odors in a space simply by placing it there.

■ 2. Humidity control effect | Because it is a breathing plant, it is resistant to both humidity and dryness.

Although rush grass is a plant , it has excellent moisture-regulating properties (moisture absorption and release). When the humidity in the room is high, it absorbs excess moisture , and when it is dry, it releases moisture little by little, helping to regulate the air.

This feature is extremely useful for people who want to keep their indoor environment comfortable without using air conditioners or humidifiers.

Areas where the effects are particularly noticeable:

  • In the rainy season or in the summer bedroom (also great for preventing night sweats)

  • Dry living room in winter

  • Around windows and entrances where condensation is likely to form

The value of rush grass is being reassessed as a "breathing flooring material" that is unique to natural materials.

■ 3. Also good for air purification and allergy prevention

Unlike synthetic fiber mats, rush grass is a material that does not easily attract dust or generate static electricity . In addition, the aforementioned moisture-regulating and deodorizing effects also help prevent the growth of mold and dust mites .

For those with allergies, or for families with small children or elderly people,
 It has gained a lot of support due to the sense of security it gives, such as "it doesn't trap air and is easy to breathe" and "it's gentle on the skin."

■ 4. Other “invisible” effects

  • Psychological relaxation effect
    The scent of rush grass contains the same components (phytoncides) as forest bathing, and is said to have the effect of regulating the autonomic nervous system .
     → Incorporating it into your work or study space can also help improve your concentration.

  • Thermal and insulating properties
     It lets out heat in the summer and blocks cold air in the winter, helping to maintain a comfortable indoor temperature regardless of the season.
