The Best Wood for Infrared Sauna

Deciding to invest in a sauna is probably one of the best decisions you can make health-wise not forgetting that you would have to select the best wood for an infrared sauna. The medical benefits sauna baths give are numerous. Asides from flushing out toxins (which is a major factor), saunas leave you feeling relaxed and healthy. For ages, saunas have been used for various medical purposes.

Infrared saunas, as the name implies, work through the use of infrared heaters. These heaters emit infrared lights which are absorbed into the body. These types of saunas are fast becoming the most popular type as they fit into the technological age which we are in.

Why Are Saunas Made of Wood?

Saunas, generally are best made of wood for various and obvious reasons. The word ‘sauna’ actually means ‘room of wood’ when translated to Finnish. Infrared Saunas are best made of wood for the following reasons:

  • Heat Insulator.
    The most obvious reason, which rules out metals (or any other sort of heat conductor), is the fact that wood is a good heat insulator. Obviously, you do not want to relax in a place which burns you upon contact. Wood absorbs heat and gives a warm and pleasant feeling when touched.
  • Hygiene.
    Wood is more hygienic and easy to maintain simply because wood contains antibacterial as well as antiseptic properties. This eliminates the risk of mould and bacteria which would ultimately defeat the aim of a sauna in the first place.
  • Heat Tolerance.
    The heat which an infrared sauna emit would most likely destroy materials such as plastic or plaster. That being said, wood is more suitable to build an infrared sauna.
  • Air Quality.
    Wood has the option of being odorless or naturally scented thereby making the air fresh and clean. This removes any need of artificial aroma therapy.
  • Natural Feel.
    Wood is natural. When trying to unwind, having an atmosphere or aura of nature around can affect ones mental well-being and aid proper relaxation.
  • Maintenance.
    Sauna wood is easy to maintain as one does not need to spend so much cleaning and putting the sauna unit in a great condition.

Types of Wood Used for Infrared Saunas

Not every type of wood is suitable for making of infrared saunas primarily because not all wood can be used for construction and those which can, do not all meet up to the requirements.

What Factors Are Considered When Picking Sauna Wood?

  • TOXICITY – Woods used for infrared saunas must possess little (to the barest minimum) or no wood toxicity as one of the main reasons people use saunas is to detoxify their bodies. Wood with little toxicity levels are kiln-dried to rid them of the toxins.
  • WOOD WEIGHT – the weight of wood plays a vital role in wood selection. The heavier wood is, the harder it is to assemble and transport. In essence, too heavy wood is a no-no.
  • AGEING OF WOOD – Not all woods age well, and as a sauna is expected to last for quite a number of years, the rate at which wood ages is a vital point to be considered. Woods which will splinter or crack cannot be used.
  • WORKING PROPERTIES – Some wood are easier to work with than others. Good sauna wood must be flexible and receptive to work.
