Many infrared sauna customers ask the question:
what about constant heat therapy? Do I need it? What's the difference?
The truth is that, for the most part, discussion about "constant
heat" is usually just marketing and product differentiation.
Below we will describe a few different types of constant heating
systems in various infrared saunas and how they work. The important
thing to remember is that as long as the surface of the heater
(whether power is running to it or not) is at least 100° F,
it will continue to produce infrared heat in the 7 to 14 micron
range.
PATENTED CONSTANT HEAT SYSTEM
A few infrared sauna companies sell a patented constant heat system
which they claim is the only way to get the true therapy benefits
for the entire session. The heaters stay running for the entire
session, but the amount of power running to the heater gets reduced.
What the patent actual describes is that once the heater reaches
a specific temperature of 120F, the power box will drop voltage
to the heater and only send half the normal current.
SAUNAS WITH STANDARD THERMOSTATS
Far infrared saunas with thermostats will allow
the sauna cabin to reach your desired temperature setting and then
shut off temporarily until the sauna unit cools down a few degrees.
The goal of designing these infrared saunas with thermostats is
to allow users to set a specific temperature for their session.
When the heaters shut off the emitters will continue to produce
infrared heat. As the heaters cool down the infrared wavelength
will actually become longer and more beneficial.
Again, it's important to remember that as long as the temperature
of the heater is above 100° F, the heater will continue to
produce infrared in the 7-14 micron range. Almost all heaters will meet this qualification,
so much of the information listed about constant heat ends up being
the result of marketing strategies.
WHAT'S NEXT?
Now that we know a little more about the heating systems of a
far infrared sauna it's time to look into the safety of the sauna.
The next part of our guide takes a look at world wide safety certifications
and how they are applied to infrared saunas.
