Sauna Weight Loss

Support a healthy weight and enhance your health and lifespan enjoyably.

Maintaining a healthy weight is key to quality of life and overall well-being. Sunlighten saunas make it easier with enjoyable sessions combining sauna and infrared light therapy. This pleasant habit supports weight management, enhances physical health, and promotes overall vitality, making it a lifestyle change you'll want to stick with. 

Saunaing: the habit you’ll enjoy creating.

The most current research shows behavior change techniques are now critical to weight management programs.1 Sunlighten saunas are beautiful, enjoyable experiences using infrared light to heat your body from the inside instead of heating the air. Infrared saunas can do more for the body’s health in a more pleasant environment (between 110 and 130 degrees) than the harsh suffocating heat of traditional saunas (180-210 degrees). Built-in chromotherapy lights create body-balancing beauty and calm.

Listen to music or watch a favorite show while the infrared light therapy does its work at the cellular level to expel toxins, increase circulation, spark metabolism, burn calories and help decrease waist size.


Sweat off those last stubborn pounds or break a plateau.

Sauna’s cardiovascular benefits are like a cardio workout.

A 2019 study compared participants’ cardiovascular effects in a sauna and on an exercise bike. The increase in heart rate was similar to a short, moderate workout. Researchers stated, "A sauna session is a physical strain. Its long-term positive effects are comparable to sports activities."2 The focus was on the benefits to the heart and cardiovascular system, rather than weight loss or muscle development. We call it a “passive cardio workout.”

Release toxins and reduce inflammation.

Studies have shown that sauna therapy can release environmental toxins stored in fat tissues that can prevent weight loss.3 Heavy metals and fat-soluble chemicals like PCBs, PBBs and HCBs can trigger the body to protect itself, resulting in the immune system’s inflammatory response."4,5 Infrared sauna therapy heats the body at the cellular level, helping to detoxify the body and reduce inflammation.

Relieve stress and lower cortisol.

Studies have shown the direct connection between stress, cortisol and weight gain. Chronic stress leads to cortisol production in large amounts, which leads to obesity and weight gain.6 Dr. Amy Myers recommends infrared sauna for weight loss to help break the connection between cortisol and weight gain by naturally relieving stress. Stress relief lowers cortisol, which can help create a healthy metabolism, thus contributing to weight loss.

Increase cellular metabolism.

People often report feeling energized after infrared sauna sessions. Cells need energy to perform their best, just like our bodies need energy to function. Near infrared stimulates cellular energy when the body’s energy-producing cells absorb the light energy (photons) and produce more adenosine triphosphate (ATP), which fuels all cells.7 This can increase cell health and performance throughout the body and all of its systems. 

As part of an overall plan, an infrared sauna is a helpful weight management tool.

Sunlighten saunas are clinically proven to reduce waist circumference.

Research proves having healthy body composition size and waist help us live a longer, healthier life.  A large Mayo Clinic pooled study showed that waist circumference is a critical factor for assessing the risk of premature death.5 As part of an overall program of nutrition, behavior change and exercise, sauna can help achieve health goals. Only Sunlighten saunas have a third-party study on our saunas: A study of diabetic patients attending three 20-minute sauna sessions per week over three months showed a decrease in waist circumference, suggesting benefit to regular sauna use.8


There is a mountain of evidence on infrared sauna use showing that it is as foundational as diet and exercise. Sauna use is a miracle practice. I love it. I use it. I benefit from it.
