Does Infrared Sauna Increase Collagen? (Exploring the Science)

Collagen is a protein that is abundant in the human body and is essential for maintaining healthy skin, hair, nails, and joints.

As we age, our body produces less collagen, leading to wrinkles, fine lines, and other signs of aging.

Many people are turning to infrared sauna therapy as a way to increase collagen production and improve the health of their skin.

But does infrared sauna really increase collagen?

In this article, we will explore the science behind collagen production and the role of infrared sauna in promoting collagen synthesis.

What is Collagen and Why is it Important?

Collagen is the most abundant protein in the human body, making up about one-third of the total protein content.

It is found in the skin, bones, tendons, ligaments, and other connective tissues. Collagen is responsible for providing structure and strength to the body, as well as elasticity and firmness to the skin.

As we age, our body's natural collagen production slows down, leading to the formation of wrinkles, fine lines, and sagging skin.

Environmental factors such as sun exposure, pollution, and smoking can also contribute to collagen depletion.

The Benefits of Collagen for the Skin

Collagen is essential for maintaining healthy, youthful-looking skin.

It provides structure and elasticity, which helps to keep the skin firm and smooth. Collagen also helps to retain moisture, keeping the skin hydrated and supple.

In addition to its structural role, collagen has been shown to have anti-inflammatory and antioxidant properties, which can help to protect the skin from damage caused by free radicals and other environmental stressors.

The Role of Infrared Sauna in Collagen Production

In recent years, infrared sauna therapy has become increasingly popular as a natural way to promote collagen production and improve skin health.

Infrared saunas use infrared light waves to heat the body directly, penetrating deeper into the skin than traditional saunas.

How Does Infrared Sauna Work?

Infrared sauna works by emitting infrared light waves that penetrate the skin and heat the body directly.

Unlike traditional saunas, which use heated air to warm the body, infrared saunas use infrared light waves, which can penetrate up to 1.5 inches into the skin.

The heat from the infrared light waves causes the body to sweat, which helps to remove toxins and impurities from the skin.

It also increases blood flow, which brings more oxygen and nutrients to the skin cells.

Infrared Sauna and Collagen Production: What the Research Says

While there is limited research on the specific effects of infrared sauna on collagen production, several studies have suggested that infrared sauna may be beneficial for skin health and collagen synthesis.

One study published in the Journal of Cosmetic and Laser Therapy found that regular infrared sauna use was associated with improved skin elasticity and a reduction in wrinkles and fine lines.

Another study published in the International Journal of Cosmetic Science found that infrared light therapy increased collagen synthesis in the skin, leading to improved skin texture and reduced signs of aging.

Infrared Sauna and Skin Health

In addition to its potential benefits for collagen production, infrared sauna has been shown to have several other positive effects on skin health.

For example, it can help to improve circulation, which can promote healing and reduce inflammation.

It can also help to unclog pores and improve the appearance of acne-prone skin.

Other Benefits of Infrared Sauna

In addition to its potential benefits for skin health and collagen production, infrared sauna therapy has been shown to have several other potential health benefits.

These include:

  • Reducing inflammation
  • Boosting immunity
  • Improving cardiovascular health
  • Relieving pain and muscle tension
  • Promoting relaxation and stress relief

Risks and Precautions

While infrared sauna therapy is generally considered safe for most people, there are some risks and precautions to keep in mind.

For example, it is important to stay hydrated during and after a sauna session to prevent dehydration.

It is also important to avoid alcohol and drugs before using an infrared sauna, as they can impair the body's ability to regulate temperature and increase the risk of overheating.

People with certain health conditions, such as heart disease, high blood pressure, or diabetes, should consult with their doctor before using an infrared sauna.

Pregnant women and children should also avoid using an infrared sauna.

How to Use an Infrared Sauna for Collagen Production

To use an infrared sauna for collagen production, it is important to follow the manufacturer's instructions carefully.

Most infrared saunas operate at a temperature of between 120 and 140 degrees Fahrenheit, and a session typically lasts between 20 and 30 minutes.

It is important to start with shorter sessions and gradually increase the time and temperature to avoid overheating.

It is also important to stay hydrated before, during, and after a sauna session.

Tips for Maximizing Collagen Production in an Infrared Sauna

To maximize collagen production in an infrared sauna, it is important to maintain a healthy diet and lifestyle.

Eating a diet rich in collagen-boosting nutrients such as vitamin C, zinc, and copper can help to support collagen production.

In addition, getting regular exercise, staying hydrated, and avoiding smoking and excessive sun exposure can all help to promote healthy collagen production.


While there is limited research on the specific effects of infrared sauna on collagen production, preliminary studies suggest that it may be beneficial for promoting collagen synthesis and improving skin health.

Infrared sauna therapy also has several other potential health benefits, including reducing inflammation, boosting immunity, and promoting relaxation.

If you are considering using an infrared sauna for collagen production or other health benefits, it is important to consult with your doctor and follow the manufacturer's instructions carefully to ensure safe and effective use.
