The Stanford Method for Ultimate Sound Sleep
The key to better sleep quality is bathing
Body temperature and sleep quality are closely linked.
When the gap between skin temperature and deep body temperature narrows, the body transitions more smoothly into sleep.
Deep body temperature naturally drops after rising, and bathing is an effective way to elevate it beforehand—helping support a smoother, more natural onset of sleep.
Leave today’s fatigue behind
for a better tomorrow
TECHNOLOGY
Rapid dissolution for fast-acting results
Full recovery with a short bath
Carbon dioxide quickly dissolves into the bath water, allowing the effects to be felt almost immediately.
Bathing in a fully dissolved carbonated bath allows the body to receive maximum thermal benefits, even during a short bath.
Designed for busy professionals who value efficient recovery.
Supports effective recovery in a short bath
Four carefully selected active ingredients are concentrated to support recovery.
By enhancing the thermal effect and promoting circulation, it helps relax muscles and ease accumulated fatigue in a short time.
Stimulate blood circulation during bathing and raising deep body temperature
Soaking the body up to the shoulders in a bath enhanced with thermal effects
gradually increases blood flow and supports a rise in body temperature.
Even on busy days, a short bath helps warm the body thoroughly from the core.

17 proven benefits and effects that support skin health
By enhancing the thermal effect of bathing, the active ingredients promote circulation and support skin renewal, helping address 17 common skin concerns.
Moisturize and protect,
a shield barrier approach
In addition to four active ingredients, the formula is enriched with beauty ingredients such as amino acid–based components.
It delivers moisture to the skin during bathing, when the skin’s barrier function tends to weaken, and after bathing, it forms a veil-like protective layer on the skin’s surface to help prevent dryness.
Address dryness and skin irritation
Moisturize and protect delicate skin
Magnesium is often referred to as a “natural moisturizing ingredient” and is believed to help protect the skin by supporting the repair of ceramides in the stratum corneum, the outermost layer of the skin, thereby aiding the recovery of the skin’s barrier function.
In addition, moisturizing ingredients such as amino acids and silk help deliver moisture to the skin and prevent dryness after bathing.
Removes chlorine from tap water
Prolongs the effects of carbonated gas
By removing chlorine, the bathwater becomes gentler and smoother on the skin.
Even after the carbon dioxide has fully dissolved, its effects last for approximately two hours.
There is no need to add another tablet, even if you enter the bath later.

HOW TO USE
Effective bathing tips for those short on time
1. Add just before getting into the bath
The tablet dissolves quickly, and adding it just before getting into the tub enhances the thermal effect of the bath.
2. Get into the bath after the tablet has fully dissolved
Get into the bath after the tablet has fully dissolved
To maximize the bath’s thermal benefits, wait until the tablet has completely dissolved in water at around 40°C, then enjoy a full-body soak. Improved circulation helps release fatigue-causing substances more easily, helping reduce daily tiredness.
3. Leave the bath without rinsing off in the shower
Showering after bathing can wash away the active and moisturizing ingredients contained in the bath tablet.
To maximize the benefits of the bath, we recommend avoiding a shower rinse after bathing.
An ideal after-work routine
After returning home
Finish dinner at least three hours before bedtime, as digestion takes time.
If eating late, choose foods that are easy to digest.
Bathing
Soak in the tub to gently raise core body temperature, and complete bathing about 90 minutes before bedtime.
At bedtime
Using BRAIN SLEEP PILLOW helps release excess heat more efficiently,
creating a better sleep environment for deeper, higher-quality rest.
