Fat Loss vs. Water Weight: While fat loss is immediate mostly water, regular use can increase the metabolism and regulate hormones such as cortisol which helps the long-term loss of fat.
Frequency Matters: For best results, use the sauna 3-4 times a week.
Safety Profile: Infrared saunas are relatively safe; there are no cases of cancer, and benefits such as detoxification and pain relief are provided.
What is an Infrared Sauna?

Before we get into the numbers, let’s get things straight on what we are dealing with. Unlike traditional steam saunas which heat the surrounding air to sweltering temperatures, infrared light saunas for weight loss use specific wavelengths of light to heat your body directly.
About 80% of the energy generated by an infrared heater heats the body and only 20% of it heats the air. This provides for a greater depth of penetration into the tissues at lower, more tolerable temperatures (usually between 120°F and 140°F). This deep heat is what causes the physiological changes that lead to the management of weight.
Does an Infrared Sauna Burn Calories? The Science Explained

The main question that every person has on their head is: does infrared sauna burn calories effectively? The answer lies in the way that your body responds to heat.
When your body is subjected to the deep heat of a far infrared sauna for weight loss, your core temperature is elevated. In order to cool itself down, your body has to work harder. Your heart rate increases and your blood vessels widen. This physiological response is very similar to what occurs when you go out for a brisk walk or a light jog.
According to the Journal of the American Medical Association, one infrared sauna session burns up to 600 plus calories. This occurs through two major processes:
- Sweat Production: Sweat production is a really energy-consuming (calorie-burning) process.
- Cardiac Output: When your heart rate increases to 100-150 beats per minute, your cardiovascular system will be performing a “passive cardio” workout.
Calorie Burn Comparison Chart
To see a visual of the efficiency, here is a comparison of average calories burned in 30 minutes for a 155 pound person:
| Activity | Estimated Calories Burned (30 mins) |
|---|---|
| Walking (3.5 mph) | 150 – 180 |
| Infrared Sauna Session | 200 – 400 |
| Running (6 mph) | 350 – 450 |
| Cycling (moderate) | 250 – 300 |
Note: Individual results vary based on weight, metabolism, and session duration.
Fat Loss vs. Water Weight What Are You Really Losing?
When stepping on the scale at the end of a session, you may see a drop. But is Infrared Sauna weight loss before and after permanent?

Does infrared sauna burn fat? Yes, over time.
Regular use of an infrared light sauna for weight loss has been related to actual reduction of fat. The deep heat penetrates into the tissues where fat is stored which may help to break down fat deposits more easily.
Furthermore, infrared therapy can help to correct imbalances in cortisol – the stress hormone that often leads to stubborn belly fat. By reducing stress and having a better night’s rest, your body becomes more efficient at naturally burning fat.

Safety Check: Can Infrared Saunas Cause Cancer?
This is a valid concern. Can infrared saunas lead to cancer? The short answer is no.
Infrared heat is nothing but radiant heat. It is the same sort of heat that we feel from the sun (without the harmful UV rays). Infrared heaters emit non-ionizing radiation which is generally considered safe by health organizations.
In fact, infrared therapy is frequently used to assist with cancer patients, to help with pain and fatigue. There is no evidence linking infrared saunas with the development of cancer, instead, the heightened circulation and detoxification aids in the immune system.
Infrared vs Steam Sauna Weight Loss

Steam saunas heat the air with boiling water, making it hard to breathe for some and limiting the time sessions can be taken to typically 15 minutes.
