FAQ

What is an infrared sauna and how does it work?
What is an infrared sauna and how does it work?

Infrared saunas use heating panels that warm the body directly rather than heating the air in the same way as a traditional steam sauna. This creates a deep, comfortable warmth that feels gentler and is often easier to enjoy for longer sessions. Many people find it a smoother, more relaxing type of heat.

How hot does an infrared sauna get?

Air temperatures are normally lower than in a steam sauna, but the heat still feels effective because it works more directly on the body. Temperature ranges vary by model, and most users allow around 10 to 20 minutes for the cabin to preheat.

What are the benefits of using an infrared sauna?

Many people use infrared saunas to help ease day-to-day muscle tension, support circulation, relax after exercise, and improve general wellbeing. The softer heat makes them suitable for regular use and appeals to those who want a milder experience than a traditional sauna.

Do infrared saunas plug into a normal household socket?

Many smaller infrared saunas are designed to run from a standard UK plug, although larger multi-person or full-spectrum models may need a dedicated circuit. Always check the electrical details on the product page and consult a qualified electrician if you are unsure.

How long should an infrared sauna session last?

Beginners often start with sessions of 10 to 15 minutes and gradually build up to 20 to 30 minutes. Many users enjoy an infrared sauna three to five times per week. Stay hydrated, pay attention to how you feel, and leave the sauna if you become light-headed or uncomfortable.

Are infrared saunas safe to use?

They are widely used in homes and spas and are generally suitable for most healthy adults. As with any form of heat therapy, drinking enough water is important. If you are pregnant, have a heart condition, or take certain medications, it is best to speak with a healthcare professional before use.

What is the difference between far infrared and full-spectrum infrared?

Far infrared is often associated with a deeper, gentler warmth, while full-spectrum models combine multiple wavelengths to create a broader heat profile. Some users prefer the softer feel of far infrared, while others enjoy the more immediate warmth of full-spectrum heaters. The product page will confirm which type each sauna uses.

Do infrared saunas need much maintenance?

Very little maintenance is usually needed. Wipe down the surfaces after use, keep any glass clean, and leave the door open for a short time so the cabin can air out. There are no stones to manage and no plumbing to worry about.

Can I assemble an infrared sauna myself?

Most infrared saunas are supplied flat-packed and are designed to slot together using pre-fitted connectors. Two adults can usually assemble one in around 60 to 90 minutes. If the sauna needs a dedicated electrical connection, that part should be completed by a qualified electrician.

Is EMF something I should be concerned about?

Many infrared saunas are designed with low-EMF technology. Where this is a feature of a particular model, it will normally be stated clearly on the product page so you can choose the option that best suits your preferences.
