Does Infrared Sauna Age Skin? (Separating Fact from Fiction)

Infrared saunas have gained popularity in recent years due to their claimed health benefits, including detoxification, weight loss, and relaxation.

However, some concerns have been raised regarding the potential adverse effects of infrared radiation on the skin, such as premature aging.

In this article, we will explore the science behind infrared saunas and their impact on skin aging.

What is Infrared Radiation?

Infrared (IR) radiation is a type of electromagnetic radiation that is invisible to the human eye.

It is emitted by the sun and various sources of heat, such as fire and electrical appliances.

Infrared radiation has longer wavelengths than visible light, and it can penetrate deeper into the skin.

Types of Infrared Saunas

There are two main types of infrared saunas: far-infrared (FIR) saunas and near-infrared (NIR) saunas.

FIR saunas use ceramic or carbon heaters to emit radiation in the far-infrared spectrum (5-15 microns), while NIR saunas use LED lights to emit radiation in the near-infrared spectrum (0.75-3 microns).

How Infrared Saunas Work

Infrared saunas work by heating the body directly with infrared radiation.

The heat penetrates the skin and raises the body’s core temperature, which can induce sweating and other physiological responses.

Benefits of Infrared Saunas

Infrared saunas have been touted for their potential health benefits, including:

  • Detoxification: Sweating can help eliminate toxins and heavy metals from the body.
  • Weight loss: Infrared saunas can increase metabolism and burn calories.
  • Relaxation: The heat can help reduce stress and promote relaxation.
  • Pain relief: Infrared saunas can alleviate pain and inflammation.

Can Infrared Saunas Age Skin?

There is some concern that infrared radiation from saunas can cause skin aging, including wrinkles, sagging, and hyperpigmentation.

However, the evidence for this is limited and inconclusive.

Understanding Skin Aging

Before we can evaluate the impact of infrared saunas on skin aging, we need to understand what causes skin aging in the first place.

What Causes Skin Aging?

Skin aging is a complex process that is influenced by both intrinsic (internal) and extrinsic (external) factors.

Intrinsic factors include genetics, hormones, and metabolism, while extrinsic factors include sun exposure, pollution, smoking, and other environmental factors.

How Does Infrared Radiation Affect Skin?

Infrared radiation can penetrate deep into the skin and generate heat, which can cause cellular damage and inflammation.

However, the extent and severity of this damage depend on various factors, such as the wavelength and intensity of the radiation, the duration of exposure, and the skin’s natural defense mechanisms.

Can Infrared Saunas Improve Skin Health?

While the evidence for infrared saunas’ anti-aging effects is limited, some studies suggest that they may have beneficial effects on skin health.

For example, a 2017 study found that FIR saunas can improve skin texture and reduce roughness in postmenopausal women. 

Additionally, a small study published in 2016 found that NIR therapy can improve skin elasticity and reduce wrinkles in women aged 30-55.

However, it’s important to note that these studies are limited and have small sample sizes, so further research is needed to confirm these findings.

Tips for Safe Infrared Sauna Use

To minimize the potential risks of infrared sauna use, it’s important to follow some basic safety tips:

  • Stay hydrated: Drink plenty of water before, during, and after your sauna session to prevent dehydration.
  • Limit your exposure: Start with short sessions (10-15 minutes) and gradually increase the duration as your body adjusts.
  • Protect your skin: Apply a moisturizer or barrier cream to your skin before entering the sauna to minimize the risk of dryness and irritation.
  • Avoid alcohol and drugs: Avoid using drugs or alcohol before or during your sauna session, as they can impair your body’s ability to regulate temperature and increase the risk of dehydration.
  • Consult with your doctor: If you have any underlying medical conditions or concerns about using an infrared sauna, consult with your doctor before starting.


Infrared saunas have gained popularity in recent years for their claimed health benefits, including relaxation, detoxification, and weight loss.

While there are some concerns that infrared radiation may cause premature skin aging, the evidence for this is limited and inconclusive.

Furthermore, some studies suggest that infrared saunas may actually have beneficial effects on skin health.

To minimize the potential risks of infrared sauna use, it’s important to follow some basic safety tips and consult with your doctor if you have any concerns.


  1. Can infrared saunas cause skin cancer? There is no evidence to suggest that infrared saunas cause skin cancer. However, excessive exposure to any form of radiation, including infrared radiation, can increase the risk of skin damage and cancer.

  2. Can infrared saunas damage my eyes? Infrared radiation is not harmful to the eyes, but it can cause temporary discomfort if exposed for prolonged periods. It’s recommended to close your eyes or wear protective goggles during an infrared sauna session.

  3. How often should I use an infrared sauna? The frequency of infrared sauna use depends on your individual needs and health status. It’s recommended to start with one or two sessions per week and gradually increase the frequency as your body adjusts.

  4. Can infrared saunas help with acne? There is limited evidence to suggest that infrared saunas may have beneficial effects on acne-prone skin by reducing inflammation and promoting detoxification.

  5. Are there any side effects of using an infrared sauna? Some potential side effects of infrared sauna use include dehydration, dizziness, nausea, and skin irritation. It’s important to stay hydrated and follow basic safety tips to minimize the risks.
