What is Alkaline Water?

What is Alkaline Water?

You’ve heard of alkaline water, but what is it?  Get the facts about the benefits, history and more.

Alkaline water (otherwise known as electrolyzed reduced water) is water with a pH of greater than 7. The amount of hydrogen mixed in with the water is known as Potential Hydrogen (pH). The pH scale ranges from 0 to 14; A pH of 7 is neutral, meaning the water is neither acidic nor alkaline. A pH of 7 through 14 indicates the water is alkaline, and a pH of 0 through 7 indicates the water is acidic.

In nature, water gets alkalinity from the minerals it absorbs. The most common minerals found in alkaline water are calcium, magnesium and potassium. These minerals are commonly found in tap water as mineral carbonates such as calcium carbonates and magnesium carbonates. Tap water rich in mineral carbonates is considered to be hard water.

Did you know? Hard water with its mineral carbonates can also be alkaline water if it has a pH of greater than 7. But it’s not the same kind of alkaline water that you get from a water ionizer!

Water ionizers make tap water more alkaline by separating the minerals from the carbonates. Once freed of the carbonates, the minerals chemically combine with hydroxyl ions taken from water molecules – to form mineral hydroxides. These mineral hydroxides – calcium hydroxide and magnesium hydroxide are recognized by the FDA for their contribution to human nutrition (FDA GRAS)

Alkaline water from a water ionizer has been in the USA for about 20 years, but has been studied and consumed in Asia for over a 50 years. The US FDA has not evaluated alkaline water for health purposes since it is not considered a drug; the information on this page about alkaline water comes from Japan and the Mayo Clinic in the USA.

Voluntary Drinking Guidelines: Alkaline Water in Japan

The Association of Alkaline Ionized Water Apparatus (AAIWA) of Japan defines alkaline water as: “Alkaline ionized water is slightly alkali electrolyzed water with a pH of 9 to 10 created on the anode side by direct-current electrolysis of drinking water

In Japan, voluntary guidelines regarding the use of alkaline water have been established by the AAIWA based on standards set forth by the Japan Home-Health Apparatus Industrial Association and Japanese Standards Association. Some recommendations are:

  • Individuals receiving medical attention or believe they have health problems should consult their doctor before drinking alkaline ionized water.
  • A pH of 9.5 is recommended for daily use
  • Don’t take medication with alkaline water, instead use the purified mode on your ionizer to create purified water. (Association of Alkaline Ionized Water Apparatus 2010)

This information is provided for educational purposes only; these guidelines have not been evaluated by the US FDA.

Alkaline Water and the Mayo Clinic

According to Mayo clinic nutritionist Katherine Zeratsky: “Some studies suggests that alkaline water may help slow bone loss, but further investigation is needed to determine if this influences overall bone mineral density and if the benefit is maintained over the long term.” (Zeratsky, K)

Is Alkaline Water right for you?

LIFE Ionizers urges you to talk to your doctor if you are considering alkaline water. Make sure that you contact a doctor who has knowledge of water quality. Be careful, doctors that don’t understand water quality may suggest you drink tap water that has contaminants in it. Most doctors are unaware that there is even a difference in the many types of water available.

Micron Power Select™ allows you to vary the infrared output from each TheraMitter™ zone and control the infrared micron range during your sauna session. TheraMitters™ can be exclusively customized to a surface temperature between approximately 450°F down to an amazing 126°F. This is a extremely useful feature for multiple sauna users. For example, the person on the right can set their back TheraMitters™ on full power and their feet to half power while the person on the left can set their back TheraMitter™ to 80% power and their feet to 60% power. This highly innovative feature allows you to program your sauna to your personal comfort level. The MPS settings can be adjusted from 100% to 7% for each zone. On the MPS Touchview Control screen in "MPS SETUP," you can choose the level for each TheraMitter™. The levels can be set in any combination at 7%, 13%, 20%, 27%, 33%, 40%, 47%, 53%, 60%, 67%, 73%, 80%, 87%, 93%, or 100%.

The SpectraWave™ function is an exclusive feature that allows the sauna to move through a specific infrared spectrum. The sauna’s onboard computer system has 8 different pre-selected power settings and it will scroll through a new setting every 2 minutes. This feature allows TheraSauna® to produce near, middle, and far infrared energy when this feature is utilized. See below for some sample SpectraWave™ power settings:

TheraSaunas® far-infrared is produced during the entire sauna session.  When the sauna reaches temperature, the patented MPS Therasauna® Touchview™ 3.0 idles the TheraMitters™ down to surface temperature of under 230°F. The TheraMitters™ will return to 400°F and above when necessary, keeping a steady temperature and micron range. The far-infrared produced is still consistently reaching the optimal 9.4 micron range for human absorption due to the unique physical design of solid ceramic TheraMitters™, penetrating up to 2” below the skin. This creates an environment where the user receives more infrared in 20 minutes than they would during a 40 minute session in other brand saunas. Therasauna® produces zero cold spots when operating and does not vent plastics and carbon fibers  into the sauna cabinet, unlike our competitors. Carbon saunas only reach the one surface temperature of approximately 230°F and turn off after reaching their set convection air temperature, losing air temperature and creating an ineffective range of infrared. The TheraSauna® Stable Heat™ System does not turn off, but powers down and sends a trickle charge of electricty to maintain the surface temperature of the TheraMitters™, thus consistently reaching the 9.4 micron range of far infrared.

The best example of how TheraSauna's® Stable Heat™ System works in relation to our competitors is to imagine a light switch. If the light switch is flipped on, the light in the room will turn on. The moment the switch is turned off, the light goes out and the room is dark. Infrared is a form of light, just like the visible light in the example, but on a different spectrum that is invisible to the naked eye. TheraSauna's® Stable Heat™ System remains on during the entire sauna session, meaning infrared is produced the entire sauna session, just like turning on the light with the light switch and leaving it on the whole time you are in the room. In a competitor's sauna, the infrared will be produced until the set temperature is reached. The moment the set temperature is reached, infrared immediately stops being produced, just like shutting off the light with the light switch. No more infrared is being produced, just like flipping the light switch to off turns off the light. So, it's much like sitting in a room with the lights on for 40 minutes, but you have to sit in the dark for half of the time. Our Stable Heat™ System prevents this from happening in TheraSauna®, giving the user a clear advantage in the amount of exposure to far infrared.

This patented, 7 Day Programmable Control allows you to set the desired time your sauna will turn on Monday through Sunday. You can set the timer to pre-heat the sauna for you so that it is ready when you get home from work or when you wake up in the morning. Getting into a cold sauna and waiting for it to warm-up is a thing of the past. Just press, set and forget... the TheraSauna® will remember the rest. The onboard computer memory will hold the settings in memory even if the sauna experiences a power failure.
