What is an infrared sauna blanket?

An infrared sauna blanket is a portable heat therapy device designed to wrap around the body while you rest. It’s a compact, at-home way to experience infrared heat therapy without needing a full sauna cabin.

The BON CHARGE Infrared Sauna Blanket uses far infrared heat, along with multiple supportive layers, to create a warm, sweat-inducing session from the comfort of home.

It’s designed for people who want the benefits of sauna-style heat therapy without needing the space, installation, or cost of a traditional sauna.

How does the Infrared Sauna Blanket work?

The BON CHARGE Infrared Sauna Blanket uses far infrared heat to warm the body directly.

Far infrared is part of the infrared spectrum. It’s invisible to the human eye, but the body experiences it as warmth.²

Rather than mainly heating the surrounding air, far infrared heat is absorbed by the body’s surface tissues, helping create a deep warming effect.

As your body warms up, it begins to activate natural thermoregulatory responses, including:^{1, 3}

• increased blood flow to the skin
• a temporary rise in heart rate
• sweating
• relaxation of muscles
• a whole-body heat response

This is why using an infrared sauna blanket can feel similar to being in a sauna, but in a more compact and convenient format.

What happens in the body during a sauna blanket session?

During a sauna blanket session, your body works to regulate temperature.

As heat builds, blood vessels near the skin widen, helping move blood toward the surface of the body. This process supports circulation and helps your body release heat through sweating.

Your heart rate may also rise temporarily, similar to the way it can during mild exercise or passive heat exposure.

This does not replace exercise, but it does create a gentle cardiovascular-style heat response.

Heat exposure may also activate heat-stress pathways, including heat shock proteins. These proteins help the body respond to thermal stress and support cellular resilience.^{1, 3}

Benefits of using an Infrared Sauna Blanket

The BON CHARGE Infrared Sauna Blanket may help support:

• Relaxation: The warmth of an infrared sauna blanket can help create a calm, wind-down state, making it a useful addition to an evening or recovery routine.
• Sweating: Infrared heat encourages sweating, which is part of the body’s natural cooling process.
• Circulation: As the body warms, blood flow increases to help regulate temperature. This may support a feeling of warmth, comfort, and recovery.
• Muscle tension and soreness: Heat can help relax tight muscles and ease feelings of stiffness or soreness, especially after exercise or a busy day.
• Recovery routines: Many people use infrared sauna blankets as part of a broader recovery routine alongside stretching, hydration, rest, and light movement.
• Cardiovascular-style heat stress: Because sauna-style heat exposure can temporarily increase heart rate and circulation, it may support cardiovascular wellness as part of a healthy lifestyle.

How is an Infrared Sauna Blanket different from a traditional sauna?

A traditional sauna heats the air inside a sauna room or cabin. This hot air then warms your body.²

An infrared sauna blanket uses far infrared heat to warm the body more directly while you lie inside the blanket.

This means an infrared sauna blanket can offer a sauna-style experience in a smaller, portable format.

It can be used at home, folded away after use, and does not require a dedicated sauna room.

How often should you use an Infrared Sauna Blanket?

If you are new to infrared heat therapy, start with one to two sessions per week.

Begin with a lower temperature and shorter session, around 10–15 minutes, then gradually increase as your body adapts.

For regular use, many people use an infrared sauna blanket around two to four times per week, depending on their goals, tolerance, and routine.

Always follow the manufacturer’s instructions and listen to your body.

Tips for using the BON CHARGE Infrared Sauna Blanket:

• Always read the instructions and follow the directions for use: Use the blanket as directed, including recommended temperature, session length, setup, and safety guidance.
• Start low and slow: Begin with a lower temperature and shorter session, especially if you are new to heat therapy.
• Hydrate before and after: Sweating increases fluid loss, so drink water before and after your session.¹
• Wear comfortable clothing: Light, breathable clothing or a towel layer can help keep the session comfortable and hygienic.
• Listen to your body: Stop if you feel dizzy, lightheaded, nauseous, or overheated.
• Cool down gradually: Give your body a few minutes to return to normal before showering or moving on with your day.
• Avoid alcohol: Alcohol can increase dehydration and make heat exposure less safe.
• Clean after use: Wipe down the blanket after each session, allow it to cool, and store it properly.

Who should be cautious with Infrared Sauna Blankets?

Infrared sauna blankets may not be suitable for everyone.

Speak to a healthcare professional before use if you are pregnant, have medical implants, cardiovascular concerns, have low or unstable blood pressure, are prone to fainting, have heat intolerance, or take medication that affects sweating, hydration, or blood pressure.

You should also avoid use if you feel unwell, dehydrated, or overheated.
