With our far‐infrared Hot Yoga systems, the Hot Yoga participants are surrounded by healthy, tranquil and soothing warmth. No excessive hot air stacked at the ceiling also means no temperature diﬀerences between exercising while sitting or standing, and for the studio operator, no unnecessary warmth or energy‐losses. In most Hot Yoga applications, a portion of the panels is controlled by a standard thermostat to keep the room at “room temperature” (far‐infrared keeps the ﬂoor at or very near the thermostat’s temperature; hence, it shortens the pre‐session “warm‐up time”).
With Far‐infrared it is not necessary to use a special Hot Yoga thermostat. Prior to a session, the instructor (or a pre‐programmed timer) switches the panels “on” and leaves these on during the session. The advantage of this approach is that the participants do not notice any changes in warmth. With a thermostat, (just like with a hot air system), the panels are switched “oﬀ” when the thermostat reaches its pre‐set temperature and “on” again when the temperature has dropped. To some, this cycling feels like a cloud passing between them and the sun; this upsets concentraon. The studio operator also has the option of installing a “comfort‐controller” to allow the instructor to set the correct “Yoga intensity” (panel surface temperature).
From the image above, it is clear that the thermostat’s reading does not reflect the room’s true temperatures. The room may be at “41 degrees Celsius”, but the participants are distracted by the cold airﬂow across the mats.

True Far‐infrared Hot Yoga
Far infrared radiant heating technology operates in the healthy and therapeutic “long wave length” part of infrared spectrum (7,000 to 10,000 nanometers, or 7‐10 micrometers). Products producing this wave length are commonly used for physiotherapy treatments. These far‐infrared waves penetrate only the upper 0.040” (1 mm) of the skin where these simulate the blood‐ﬂow, allowing the body to detox and “refresh” itself.
Far‐infrared is soothing, it allows the yoga participants to relax and concentrate without the annoying noises and cold drafts normally associated with convection heating. Far‐infrared surrounds the body with tranquil warmth.
Because far‐infrared does not heat the air, there are very signiﬁcant energy savings over traditional systems. The “room temperature” with infrared is the actual temperature of the space; there is virtually no diﬀerence be‐tween the temperature at the thermostat’s elevation and the ﬂoor. Hence, an eﬀective “Hot‐Yoga‐temperature” could be as low as 24 degrees Celsius or 75F (see image below), or as high as the instructor desires.
Traditional Hot Yoga
Most HotYoga heating systems today work on the principle of convection.
As detailed in section 1“ convection”, air is heated and makes its way into the Hot‐Yoga studio. Once the heated air enters the room, it rises and, as it moves away from the source, it cools. The cooled air makes its way down and is “pulled” across the ﬂoor.
This “convection ﬂow” across the ﬂoor actually cools the HotY ogaparticipants, and the thermostat must be set higher to help reduce this cooling eﬀect. No matter how well the system works, there will always be an imbalance because hot air rises, and cold air descends; the higher the ceiling, the colder the return air ﬂow, making it diﬃcult for the participants to concentrate. With Hot Yoga, the “thermostat eﬀect is even greater than with traditional convection room‐heating: While a thermostat may read “an eye‐level temperature” of 41 degrees Celsius (105°F), the ﬂoor’s temperature may be at 13 degrees (55°F), while the ceiling could be at 62 degrees (145°F) or higher. The following sketch explains the temperature distribution over the room’s height. If the room has a very high ceiling, the ceiling temperatures can even be higher, and the ﬂoor‐temperatures lower.
