"Magma Spa" born from a revolutionary idea - a revolutionary device used by over 2 million people a year -

We interviewed Koizumi-san, the CEO of Magmaspa Japan Co., Ltd., who has raised the body temperature of over 2 million people annually with the revolutionary "Magmaspa" device, focusing on the keyword "core body temperature" which is crucial for improving sleep quality.

Background of Magma Development

An energy environment of +1℃

This body temperature-raising business was created as a result of various research efforts spurred by my younger brother's cancer. There are many ways to treat cancer, but I focused on "body temperature" because it became clear that "body temperature" is the source of the human body's natural healing power.

At one point, I learned that a body temperature of +1-2°C (38-39°C) maximizes the power that governs immunity. I thought, "Well then, if my brother is going to keep undergoing chemotherapy and getting better, all we need to do is raise his rectal temperature (core body temperature)!"

So I thought about how to raise my brother's core body temperature and first tried it on myself. However, even if I took a hot bath or went into a sauna to warm my body, my rectal temperature only reached 37.0-37.5°C, not rising by 1°C. I would get lightheaded before it could rise enough.

If externally warming the body didn't work, what other way could I warm the human body as a substance? I thought, "...How about a method of transferring heat to the human body with light? If I could strengthen the power of far-infrared rays (solar radiation) reaching the earth...!"

But simply basking in the sun wouldn't raise my body temperature by 1°C. So, I investigated how much thermal energy needed to be increased to raise body temperature by 1°C.

It was "41.25°C". I just needed to create an energy environment of 41.25°C or higher. For example, if you want to raise your external body temperature from 36.5°C to 37.5°C, which is +1°C, and you call this +1°C "X", then if you add 3.75°C, the resistance value of human muscle and fat, to this X, you get 41.25°C.

Analysis of Thermal Energy and Conflict

I considered how to achieve that 41.25°C. Things in the natural world that retain heat reflect that heat.

Among them, there were materials like charcoal and ceramics with the highest reflection efficiency. The reflective power of charcoal and ceramics is said to be about 80%.

So, if it's 80%, how hot do you need to heat it to get 41.25°C? If you heat charcoal to 50°C, with an 80% reflection efficiency, it will emit about 40°C of heat energy. This means that if you heat it to 52°C, it will be 41.6°C.

Simply put, if you lie on charcoal heated to 52°C, you would get 41.6°C of thermal energy, but there's a limit to the temperature at which the skin inflames, so it didn't work. If we expose our bodies to 52°C, we would get low-temperature burns.

The human body has a critical temperature of "46°C." Exceeding this temperature significantly increases the risk of inflammation.

■Summary

If an energy environment of 52°C can be created, 41.25°C (41.6°C), which raises body temperature by 1°C, can be produced.

→However, this causes low-temperature burns. The limit for low-temperature burns is 46°C.

An energy environment of 46°C results in 36.8°C.

→This is pointless as it doesn't raise the human body temperature by +1°C.

Encounter with Lava Plates

So, we thought, wouldn't it be better to increase the reflection efficiency with a different approach? We hypothesized that a material with over 90% reflection efficiency would emit enough thermal energy to warm the human body.

However, the ray of hope was temporarily extinguished. After about two months of receiving hints from various researchers and frantically searching, we found that there was no material with a far-infrared reflection efficiency of 90% or more, and this fact had not been confirmed.

But this situation actually motivated me. I thought that if it didn't exist, it should, and I resolved to find it myself if no one else had.

Another two months passed, and then something happened when summer arrived. I owned a villa by Lake Kawaguchiko at the time, and I had BBQ equipment there. Among the BBQ equipment, there was a plate made from a cut of Mount Fuji lava, which we decided to use.

The owner of a yakiniku restaurant I knew brought a lot of steaks, and since there were about 30 people there and it would be difficult to cook everything, we decided to use a regular griddle as well. Since lava doesn't cook quickly, we used both the griddle and the lava to cook thick steaks at once. At that time, many people requested rare, so we started serving rare first.

Looking at the surface (sear) of the meat grilled on the griddle, I thought it was rare and cut it. The griddle-grilled meat had a nice sear and was perfectly rare. So I thought the lava-grilled meat would be good too, and cut it into easy-to-eat pieces, but it wasn't rare; it was thoroughly cooked...! In other words, with lava, the heat conduction is strong, so even though the surface wasn't seared, the inside was thoroughly cooked.

If you apply that to human skin... I had an "Aha!" moment. I sent a cut plate of Mount Fuji lava for testing, and it showed a far-infrared reflection efficiency of 93.2%. With this high reflection efficiency, I was confident that it would reach an energy environment of 41.25°C.

Next, the challenge of how to heat it arose, so I decided to actually visit the Aokigahara forest, where Mount Fuji's lava is located.

We discovered that the temperature inside the lava caves in the Aokigahara forest was more than 20°C lower than the outside air. Moreover, the water that had been seeping in for a long time contained dissolved mineral components from the lava.

So, I wondered how comfortable an environment it would be if we inverted and heated this system of Mount Fuji's Aokigahara forest.

In Mount Fuji's Aokigahara forest, trees grow directly from the lava. This means that lava not only contains water but also has enough minerals to support tree growth. As trees grow in the forest, their leaves fall, decompose into humus, and become soil. This cycle can only be established in a forest that has existed for thousands of years. Everything is a natural process formed by the lava within the earth. The Magmaspa device is a system that inverts this natural process!

Inside the Magmaspa, humidity is constantly maintained at 70%. The principle of Magmaspa is as follows:

1. Heater heats water
2. Water vaporizes
3. Heated and vaporized water molecules most easily attach to mineral components
4. Water vapor with attached mineral components passes through the lava layer and emerges
5. The space is filled with the same pure hot spring water or dispersed mineral water

That's why breathing is so easy. This is completely different from a sauna or a heated room.

About Magmaspa

Hot yoga is tough! Magmaspa is comfortable!

Underneath this rock bed, there is a layer of nearly 40 different types of "medicinal stones." Raw crystals, tourmaline, and lava marimo are laid out in this layer, and steam rises from beneath them.

These lava plates are actually made from lava at the foot of Mount Fuji, meticulously cut one by one with a diamond cutter and laid out. In other words, all of this is Mount Fuji lava. As you will realize when you lie down on it, this is a warmth that comes from nature. In other words, we are not "making you hot," but "warming" you.

If you stay here for 20-30 minutes, you'll sweat profusely. You'll sweat about 1.5-2.0 liters in an hour. Hot yoga makes you feel hot, so staying there for a long time is difficult, isn't it? Humidified and heated hot yoga uses a humidifier and heater to heat the space, making you "feel hot," which is completely different from Magmaspa! Magmaspa is a device designed to raise your body temperature by 1°C, so you'll feel "warmed" from the inside.

Who are the people who come here?

Most of the people who come here now are not looking to build a lot of muscle, but rather to maintain their current body without putting a lot of stress on it. However, some people are positively looking to lose weight, and others are attracted by the fact that fat burning doubles.

Our company has introduced its system to Jungle Gym, a gym favored by celebrities, and when it was featured on a TV program some time ago, it achieved the astonishing result of "a 106kg girl losing 52kg in 10 months." Only magma can achieve this in such a short period!

Since humans cannot maintain their mental state, it is important to increase energy metabolism in the shortest possible time. Raising body temperature is so natural that it often becomes a blind spot.

In modern society, we tend to think that "not moving = becoming affluent." In our daily lives, opportunities and factors to move our bodies, such as cleaning, shopping, and commuting, that is, opportunities to "raise body temperature," seem to have decreased compared to before.

"Where does low body temperature come from?" It comes from the convenient systems of developed countries. If you don't move, you don't use your muscles, which leads to low body temperature. In other words, we are creating the causes of our own physical ailments. Humanity is evolving towards lower body temperatures (lower immunity). Yet, viruses like influenza are becoming more rampant each year. You can already see what will happen, right?

Temperature Change x Sleep

The link to sleep is the "rise in core body temperature" caused by the Magmaspa device. Using this, we presented evidence at the Japan Anti-Aging Medical Society that "core body temperature (deep internal body temperature about 5cm from the anus) = rectal temperature rises by 1°C or more."

While a 1°C drop in core body temperature can lead to truly good sleep, to compensate for this 1°C difference, the baseline must be restored to an appropriate body temperature. If the body temperature is not appropriate in the first place, it is impossible to get proper sleep. All you need to do is enter "Magma." This is because, while there are various approaches such as diet and bathing, "Magmaspa" is the most effective in delivering energy to the core body temperature.

"The important thing is to narrow the difference between skin temperature and core body temperature." Dr. Nishino of Stanford University also states that "the key to improving sleep quality is raising and lowering core body temperature!" Source: Stanford's Best Sleep, p. 131

As mentioned above, it is important to create a range where the core body temperature can be narrowed. One way is bathing, and another is the Magmaspa.

Koizumi-san's Sleep Philosophy

Weekly Body Temperature Increase

I train once a week at Magmaspa. I've always had good sleep habits and sleep soundly! Yesterday, I went to bed at 9 PM and woke up at 4 AM. This sleep duration (7 hours) is consistent.

For example, if I go to bed at 10 PM, I always wake up at 5 AM. Also, I like to drink a lot of alcohol and eat rich foods like meat, so I tend to have a lower body temperature in my daily life. Therefore, I diligently manage my body temperature with Magma.

German-born Healing Music

There's music I've become hooked on for falling asleep. It's called "Endel," a personalized, automated healing sound generation app born in Berlin, Germany.

I'm generally a good sleeper and don't have stress about sleeping, but I chose a sound-based approach to further enhance its quality. Not getting good sleep is akin to not living a good life.

Finally

Mission: To raise human body temperature

I directly manage 8 stores, including franchises, but there are 102 stores nationwide that have introduced our system. The reason it has spread so widely is simply because it faithfully reproduces the laws of nature. It's not because I was a good salesperson; I simply created something that feels good.

While awareness hasn't exploded, people who experience it are delighted, and it's spreading by word of mouth. That makes me very happy.

"To raise humanity's body temperature" is my mission. My job is to create an environment where body temperature can always be maintained and to spread what humanity needs to the world. My goal is to "cure a vast number of people with low body temperature rather than achieving vast profits."

Editorial Department Experience Log

After the interview, we, the Brain Sleep editorial department, also participated in a trial lesson! We experienced the "Magma Yoga Healing Detox" at Magmaspa Studio Insea Ebisu, which is easy for beginners to try.

Magma Yoga Healing Detox is described as a session "focused on seated poses, which brings the body closer to the lava plate, warming the entire body, promoting relaxation of mind and body, and encouraging detoxification."

In conclusion, it was simply A-MA-ZING!! When you experience it, you'll understand that the feeling of waste products gushing out from inside your body with a massive amount of sweat is incredible. Even without doing any strenuous training, I sweated this much.

After experiencing it, I truly felt the following:

• Lava bathing feels incredibly good
• The body warms up quickly (compared to other hot yoga studios)
• Easy to follow explanations, so even beginners can do it easily
• Sweat starts pouring out intensely within about 10 minutes
• Afterwards, your skin feels shiny and supple

By the way, the personal training space can be accessed through a back entrance, so you don't have to make eye contact with other users at the reception or entrance. You'll definitely feel the effects, so please give it a try!
