What to Know When Buying a Sauna

The primary benefit of infrared saunas is to sweat out a lifetime accumulation of environmental and other chemical toxins that may be reducing wellness, vitality and energy.


Everyday Toxin Exposure Before You Ever Step into a Sauna

Before you compare sauna models, it helps to understand just how many toxins quietly accumulate in the body year after year. A truly therapeutic sauna should help you safely sweat out what daily life keeps putting in.

 

Toxins are absorbed daily from breathing air 24/7 with vehicle and factory pollutants

EPA lists 187 toxins discovered in the air we breathe. Once in the lungs, they likely accumulate in the body and affect body chemistry and may reduce vitality a tiny bit each year for 20 to 60 years.

Other chemical toxins are ingested from pesticides and herbicides in fruits and vegetables

Especially if not washed well unless organic. Additives to some liquids we drink. Preservatives like nitrates in prepared meats. Preservatives and coloring in many food products. Read the labels.


Additionally, soaps, shampoos, and body washes are usually full of chemicals, per the labels and are absorbed through the skin.

These chemical toxins accumulate over the years into sometimes a substantial toxin load on the body that disrupts body chemistry, vitality and energy.


Microplastics: A New Layer of Toxic Load

The average person may be ingesting 30,000 micro bits of plastic yearly from seafood, plastic bottles, wraps and plastic food containers, cups and more. Search: Micro Plastic Foods

“The average person eats thousands of plastic particles every year,” study finds.

The more researchers look, the more microplastics they find — in seafood, table salt, drinking water, and even the air we breathe. These tiny fragments can make their way into our digestive system and tissues, adding yet another layer to the body’s overall toxic load.

Environmental medicine doctor, Sherry Rogers, in her book, Detoxify or Die , says that toxins can mimic disease and this is not always recognized. She says that the best way to remove toxins is with an infrared sauna, and it is the only way to remove plastics. Here are some excerpts from her book.

Relax users frequently comment on the improved feeling of wellness, mental clarity, better sleep, better skin and complexion, and energy after a number of high sweat sessions. There are tens of thousands of wood infrared saunas, largely in homes, in which toxins are sweated out — it just takes longer, often up to 40–45 minutes for a good sweat session versus speedy Relax saunas in 15–20 minutes, plus face, eyes and hair stay cool and mostly dry.


Types of Saunas

Infrared is part of the beneficial rays of sunlight. There are three types depending on the length of the light wave: near, medium and far. Far penetrates the most and is considered the most beneficial. It’s the heat you feel on a winter day coming through your jacket, or the warmth that can hatch turtle eggs buried in the sand.

Fitness clubs usually have a steam room and a dry heat sauna with water poured over rocks or a hot stove. These largely benefit the skin and lungs. Some have wood infrared saunas.

A far infrared sauna heats the body from the inside, raising core temperature so the body sweats to cool itself off. This sweat brings out toxins from the tissues and also dumps them into the urine. The Relax Sauna is the only known sauna that can raise core temperature as much as 3 degrees in about 25 minutes.

Infrared Generation with Commonly Used Carbon Panels

The most commonly used method to generate infrared in saunas is with one or more carbon panels hung on the sides of the sauna. A carbon panel is a large piece of fabric impregnated with carbon. It is electrically heated and emanates a mild amount of infrared.

Normally, carbon panel saunas — from small portable units up to large wooden cabins — take 10 to 20 minutes to fully heat up, and up to 40–45 minutes for a full sweat.

Relax® Advanced Technology

The inventor of the Relax Sauna said it took him ten years to figure out how to generate larger amounts of far infrared. He developed a semiconductor-like chip that filters out near and medium infrared and concentrates the most beneficial far infrared. Then he placed the chips in front of a motorized generator that pushes energy through, which is converted to far infrared by the chips instantly — and in large, therapeutic volumes for fast benefits and sweating sessions of only 15 to 20 minutes, saving time over traditional carbon panel saunas.

The inventor patented his invention in three countries and received awards and recognitions. This was in the early 1990s. Since then, tens of thousands of folks worldwide have benefited from this huge advancement in far infrared therapy. The inventor keeps the price uniform so there is no need to shop around.

A lady told us that she ordered a small (carbon panel) sauna, likely from China, and a Relax Sauna at the same time as both had 30-day returns. She said the carbon panel sauna got hot but did not produce the fast profuse sweating like Relax, so she returned it. Both looked the same on the outside, but it is “under the hood” that matters.

Saunas in General Have Been Widely Researched and the Benefits Are Well Known

 

“On the other hand, no adverse effects have been reported with infrared saunas. So if you’re considering trying a sauna for relaxation, an infrared sauna might be an option.”
