Hot Album Carbonated Spring Tablet Co., Ltd. (Headquarters: Hachioji, Tokyo; Representative Director and President: Shigeharu Koboshi), the inventor and developer of pure heavy carbonate bath additives with patented manufacturing technology, and a pioneer in the industry providing OEM to many manufacturers, has welcomed Miyu Nagaoka, former Japan Women's Volleyball National Team player, as its brand ambassador.

Ms. Nagaoka re-evaluated the conventional bathing habit of "washing the body daily with soap and shampoo" and adopted the "NUCSS*" healthy bathing method, which involves simply soaking in a heavy carbonate hot tub containing only baking soda, citric acid, and vitamin C, fragrance-free, colorant-free, and chlorine-free. This bathing method provides natural cleansing, effectively washing away body dirt, as well as underarm odor and age-related odors.
By adopting this healthy bathing habit, her own recovery from various ailments and fatigue significantly improved. From this personal experience, she became convinced that "if I teach this hot tub bathing to my mother, who was prone to poor health, she will surely experience positive changes." After recommending the "natural bathing habit" of using hot tabs without soap or shampoo, she witnessed dramatic changes in just a few months, with her mother recovering her energy to the point of starting to walk again (laughs). Driven by this moving experience of "regaining health as a parent and child," Ms. Nagaoka has taken on the role of ambassador, aiming to lead a national movement to protect the health of children and parents, and to spread this new bathing habit throughout Japan.

## Why You Shouldn't "Wash Your Skin" with Soap
We have been taught that "washing with soap is clean," but it seems a trap for modern people's ailments was hidden there.
## Detergents Strip Away and Remove the "Natural Sebum Barrier":
Sebum, which decreases with age, is a "natural moisturizing cream" that surpasses high-end cosmetics. Scrubbing with soap destroys this barrier, leaving the skin in a defenseless "naked state" and exposing it to the stress of transdermal toxins.
## The True Cause of Cold Sensitivity and Nocturia:
When chemical components from soap and shampoo, and chlorine disinfectants from tap water, are absorbed into the skin that has lost its barrier and dissolve and accumulate in subcutaneous fat, the body's defense reaction constricts blood vessels and constantly secretes stress hormones, which are absorbed by the hippocampus in the brain, leading to mental damage. This tension-induced poor circulation causes capillaries to become "ghost vessels," worsening sleep and leading to "nocturia."
## Global Trends:
In Europe and the US, the warning against "over-washing"—not washing the skin with chemical detergents—has become common knowledge. For example, the UK's public health agency NHS advises against washing delicate areas with soap, recommending only water. However, in Japan, the bathing habit of using soap and shampoo, which causes cold sensitivity and skin irritation, continues under the misconception of cleanliness.
## Surprising Results from a 1000-Person Survey!
More than 90% are unaware of the risks of "over-washing." Could a well-intentioned bathing habit be draining mothers' energy?
Our awareness survey revealed a shocking reality.
Mother's Change: 73% felt their "mother's physical strength had declined." Many reported discomfort such as "feeling exhausted" or "feeling cold" after bathing.
Wall of Misconception: 74% responded that they "should wash daily with soap." Furthermore, 91% were unaware of the "negative effects of over-washing," highlighting a deep-seated "bathing misconception."
Expectations for a New Norm: 60% responded that they "want to give a bathing method that cleanses and recovers from fatigue just by soaking." Mother's Day gifts are shifting from "things" to "habits" that create a healthy future for loved ones.
## Ambassador Miyu Nagaoka Talks About Her Mother's Dramatic Before and After
Ms. Nagaoka herself suffered from "physical ailments." What she found was "NUCSS" (Not Using Chemical Stress Substances), a bathing habit that doesn't rely on soap or shampoo.
Miyu Nagaoka's comment: "First, I thought I'd try it for two weeks. But as I continued bathing without soap, my dry skin and female ailments gradually disappeared.
What made me happiest was my mother's change, more than my own. I recommended it to my mother, who used to be prone to poor health and went out less, and she quickly regained her energy, becoming so vibrant that people commented on how beautiful she looked. Now, she even started walking on her own (laughs). My mother becoming active makes me many times happier than my own changes. I want people to know the joy of giving this 'habit' to their loved ones."
