The Science of Infrared Heat vs Convection Heat

May 02, 2018 1 Comment

The word “infrared” is derived from the latin word infra (below) and the English word red. Red light has the longest visible wavelength, and infrared operates at a frequency below red light. Half the energy given off from the sun actually comes to Earth as infrared light. While we can’t technically see infrared rays from the sun, we feel it as heat.

Infrared possesses the ability to provide healing in many different regards. Infrared therapy is known to calm inflammation, reduce joint pain and boost the function of blood vessels. Studies have indicated infrared may even be beneficial in providing relief for chronic diseases. People often enjoy the benefits of infrared through infrared saunas, as research suggests saunas aid in the detoxification process by allowing the body to sweat out excess heavy metals.

Convection is the transfer of heat from a warmer place to a cooler place through a movement of fluids. A common example of convective heat would be air conditioning. The process of boiling water involves convective heat as well. As the stove heats the bottom of the pot, water begins to heat up. The hot water rises to the top, the cooler water goes to the bottom and a circular motion is created.

Another example would be traditional hair dryers, which commonly produce convective heat. A nichrome wire is used to create heat in the same way as an oven. It’s clear why many blow dryers cause such frizz and damage...your hair is being blasted with the same kind of heat that you find in an oven or a toaster!

Alternatively, infrared emits radiant heat which dries hair similarly to the way the sun does. There are three types of infrared heat: near, middle and far. The infrared bulbs we use in our cordless hair dryers emit far infrared rays, which have also been referred to as “biologically beneficial rays”.

Of the types of infrared heat, far infrared rays are known to be the healthiest for the human body. Research has shown infrared treatment may even promote new hair growth.

Ultimately, there are many benefits to choosing an infrared hair dryer over a traditional dryer!

In terms of preserving hair health, minimizing dry time and improving the quality of a blowout, infrared hair dryers are the clear choice.
