Infrared Sauna Reviews (FAQ)

Do Saunas Need Ventilation?

Yes, saunas do require proper ventilation for several important reasons. Ventilation plays a crucial role in maintaining air quality, regulating temperature, and removing excess moisture within the sauna environment. Without adequate ventilation, the sauna can become uncomfortably hot, excessively humid, and may pose potential health risks.

Proper ventilation helps to circulate fresh air into the sauna, replenishing oxygen levels and preventing the accumulation of stale air. It also helps to control the buildup of carbon dioxide and other potentially harmful gases that can be released during sauna use. By removing these gases, ventilation promotes a healthier and more comfortable experience.

Moreover, ventilation aids in controlling moisture levels within the sauna. Sweating is a natural response to the high temperatures in saunas, and without proper ventilation, the excess moisture can linger in the air, leading to a damp and uncomfortable environment. Adequate ventilation helps to dissipate this moisture, reducing the risk of mold or mildew growth and maintaining a dry and pleasant atmosphere.

Additionally, ventilation assists in regulating the overall temperature. It helps to dissipate excessive heat, preventing the sauna from becoming excessively hot and ensuring a more controlled and enjoyable experience for users.

To ensure effective ventilation, saunas are typically equipped with ventilation systems or features such as vents, windows, or doors that can be opened to allow fresh air to enter and stale air to exit. It is essential to follow manufacturer guidelines and recommendations for ventilation to maintain a safe and comfortable sauna environment.

What is a Radiant Sauna?

A radiant or infrared sauna utilizes heating panels that utilize light to make you sweat. Infrared saunas eliminate the need for steam or hot air and are ideal if you’re claustrophobic.

Should You Shower After an Infrared Sauna?

Should You Shower After an Infrared Sauna

Definitely. Any session will cause you to be extremely sweaty. Although the detoxification aspect is quite debatable, it is still good to practice proper hygiene.

How Much Space Do You Need for a Sauna?

If you’re choosing a sauna from above, it’s ideal to consider the standard 4 person model dimensions. However, you should also consider the dimensions specified in each individual item.

Normally you need at least 4 by 4 by 8 to 12 feet. You should be able to get away with a smaller room unless you plan on purchasing a 10 person sauna.

Can Infrared Saunas Be Outside?

Usually, an infrared sauna is not an outdoor sauna. However, if you take care to provide roofing for your sauna, then it should work. The main thing to remember is you need to keep it protected from the elements.

On the other hand, you might be better off purchasing an outdoor ceramic sauna or portable sauna for outdoor use.

How Big is a 4 Person Sauna?

Not too small, we went for about 2 1 / 2 feet deep. When one person comes, the other stays on the side. We built it the way it is, so we could add a bench as needed. For the shower, we built a shower room. Our condo is basically a couple of converted garages and a small apartment building all in one. Traditional Finnish sauna usually has a depth of 8 – 10 cm. (nearly 3 inches) The size depends on the number of people using it. It is placed at the center of the room and is constructed so that the visitors can all sit around it comfortably. According to many people who’ve used a traditional Finnish sauna, their imagination is often restricted due to its size.

Sauna “boards” are often strategically placed on all sides of the sauna to offer a more relaxed experience to the guests. You can fit about 5 people in the 4 person bathroom (caveat: the 4 holes on the left is really just a hole and people can crawl in the hole if you prefer).To get in, you open a hatch door (hence the tank). In the bathroom, you have a bench to sit on (no bathroom chair), a 2 person cubicle, and a shower (used by the 2 person cubicle). So, you take off your clothes, you get into the stall, and into the tank, you go. I was really surprised by how small space was and I thought that I would just curl up in the hole and stay there. But you are to get on your hands and knees (kind of like you’re sitting on a toilet), in between your “feet” you hang on and are essentially suspended in the tank. Then you lay back and straddle the arms that are on the sides (sort of like you’re leaning back and sitting on an armchair).

How Many Times a Week Should You Use an Infrared Sauna?

It might be advisable to go for infrared sauna sessions every second or third day. But you shouldn’t overdo it. How Long Should You Stay in the Sauna? A session of about two to three hours is recommended. What if You’re Vomiting or Dehydrated? If you’re feeling nauseous, move to a side room. You can stay in the sauna for up to two hours, with a five-minute break before you head back into the heat. If you’re dehydrated, replace some of the saltwater in the water with cold water to bring down your body temperature.

Drink plenty of fluids. Your body can handle up to two liters of fluid per hour. Are Infrared Saunas Safe to Do on Your Own? With the proper equipment, and you follow the rules above, infrared sauna use is entirely safe. But it’s best to go with a professional instructor, such as one of the many professionals at Schweiger Thermal Spa. They can help you prevent injury, make the most of the sessions.

Does Infrared Burn Fat?

Infrared thermal imaging burns the fat by making visible to the naked eye the heat produced by body fat and the mitochondria within it, according to the American Heart Association. It can detect areas that are particularly thick or hard to see. To use infrared thermal imaging, you first mount a camera on a laser device. Put the device against your skin and hold a numbered wristband against it. If the band begins to glow green, you have increased blood flow to those areas. To track the progress of the burns, strap on a heart rate monitor that you can wear in any location on your body (though of course, you should make sure the device is not affecting your heart rate). Once the device detects that you have begun burning fat.

How Many Infrared Panels Do I Need for Sauna?

Most saunas can accommodate one to four infrared panels. However, make sure that all infrared panels are the same brand and shape so that you can avoid thermal shock. This means that they all have to be the same size, for instance, 1/8″ x 3″ x 10″. You’ll also want to make sure that all the light and heat sources in your sauna are the same. Since the purpose of an infrared sauna is to decrease your internal body temperature and keep it constant, the hotter the lights, the higher the risk of an injury.

Some infrared saunas, like SolTherm and Sauna Gold, have heated lamps and heating elements that increase the temperature to more than 150°F. In order to keep your body temperature constant, you’ll want to use a flat infrared panel, so it doesn’t raise your body temperature above the maximum recommended 185°F. Also, do not let the panels be within two to three feet of one another, or you risk increasing your body temperature above 165°F.

How is an Infrared Sauna Different Than a Regular Sauna?

A proper infrared sauna session has been scientifically proven to reduce inflammation and improve your overall health. But what exactly are infrared saunas? They’re super hot, of course. They’ll come as a shock to those of you who’ve never experienced the heat of an infrared sauna. An infrared sauna is basically a box of body heat, and you can typically choose to get undressed to your underwear or work barefoot in them. They’re also super dry, with dry heat, and it’s recommended to stay for between 30-45 minutes.

Not only do the heat levels in infrared saunas come up to levels that are more intense than you’d experience when taking an icy plunge, but the infrared saunas heat sources are actually hot. On the highest heat setting, it’s recommended that you stay in an infrared sauna for 30-45 minutes.

What is the Rule of 200 Sauna?

The “Rule of 200” in saunas is a guideline used to estimate the safe maximum temperature for sauna sessions. According to this rule, the sum of the temperature in degrees Fahrenheit and the relative humidity percentage should not exceed 200. This rule helps to prevent excessive heat and humidity levels that can pose risks to individuals using the sauna.

For example, if the sauna temperature is set at 180°F, the relative humidity should not exceed 20% to maintain a total value of 200. Similarly, if the temperature is set at 200°F, the relative humidity should be kept at or below 0% to adhere to the rule.

Following the Rule of 200 helps to ensure a comfortable and safe experience by balancing the temperature and humidity within reasonable limits. It helps prevent the risk of overheating, dehydration, and respiratory difficulties that can arise from excessive heat and humidity.

However, it is important to note that individual tolerance and preferences can vary. Some individuals may find lower temperatures or higher humidity levels more suitable for their comfort. It is advisable to listen to your body, monitor your well-being, and adjust the sauna settings accordingly to maintain a safe and enjoyable experience.

It is also crucial to consider personal health conditions and consult with a healthcare professional, especially if you have any underlying medical concerns, before using a sauna or adhering to any specific guidelines.

Is 20 Minutes In an Infrared Sauna Enough?

The effectiveness of spending 20 minutes in an infrared sauna depends on your health goals and individual factors. In general, 20 minutes can be a beneficial duration for a sauna session, but there are some important considerations to take into account:

  1. Temperature and Sauna Type: The temperature of the sauna and the type of infrared heaters used can significantly impact the effectiveness of a 20-minute session. Infrared saunas typically operate at lower temperatures (around 120-150°F or 49-66°C) compared to traditional saunas (which can reach 170-195°F or 77-90°C). The lower temperature in an infrared sauna may require a longer session to achieve the desired therapeutic effects.
  2. Heat Tolerance: Individual tolerance to heat varies. Some people may find it challenging to spend a full 20 minutes in a sauna, while others may be comfortable. It’s essential to listen to your body and not push beyond your comfort level to avoid potential overheating or dehydration.
  3. Hydration: It’s crucial to stay well-hydrated before, during, and after a sauna session. 20 minutes of exposure to infrared heat can cause significant sweating, leading to fluid loss. Dehydration can be detrimental to health, so ensure you drink enough water to stay properly hydrated.
  4. Health Goals: The specific benefits you hope to achieve with an infrared sauna will also impact the ideal session length. For relaxation and stress reduction, 20 minutes can be sufficient. However, if you’re looking for detoxification, pain relief, or other therapeutic effects, a longer session may be more effective. Some individuals engage in multiple 20-minute sessions with short breaks in between to achieve their goals.
  5. Frequency: The frequency of sauna use is as important as the session duration. Regular use over time may be more effective than a single, extended session. This can vary depending on individual needs, but 2-3 sessions per week is a common recommendation.

It’s important to note that there is no one-size-fits-all answer to the question of how long one should spend in an infrared sauna. Personal preferences, tolerance to heat, and health goals play a significant role in determining the optimal duration. For those new to infrared saunas or who have underlying health conditions, it’s advisable to start with shorter sessions and gradually increase the duration as comfort and tolerance allow. Additionally, consult with a healthcare professional to ensure that sauna use is safe and suitable for your individual health needs.

Is Nordic Sauna Better Than Infrared Sauna?

The superiority of Nordic saunas over infrared saunas depends on individual preferences and specific health goals. Nordic saunas, also known as traditional saunas, utilize heated rocks or a wood stove to generate high temperatures, typically ranging from 150 to 195 degrees Fahrenheit (65 to 90 degrees Celsius), along with low humidity levels. In contrast, infrared saunas use infrared heaters to directly heat the body at lower temperatures, typically between 120 to 150 degrees Fahrenheit (49 to 65 degrees Celsius).

Both types of saunas offer unique benefits. Nordic saunas are believed to promote relaxation, stress reduction, and cardiovascular health through the combination of heat exposure and the production of sweat. The high temperatures in Nordic saunas can induce a deep sweat, which may help cleanse the skin, promote circulation, and support detoxification.

Infrared saunas, on the other hand, are praised for their ability to penetrate deeper into the skin, potentially providing therapeutic benefits such as pain relief, improved circulation, and enhanced muscle recovery. Additionally, infrared saunas are often preferred by individuals who find the lower temperatures more tolerable or who have respiratory conditions aggravated by high heat and humidity.

Ultimately, the “better” sauna depends on individual preferences, health considerations, and desired outcomes. Some people may prefer the intense heat and steam of Nordic saunas for its traditional ambiance and potential cardiovascular benefits, while others may favor the gentler warmth and targeted heat therapy of infrared saunas for its potential therapeutic effects and lower perceived discomfort.

It’s essential to consider factors such as personal comfort, health conditions, and desired outcomes when choosing between Nordic and infrared saunas. Consulting with a healthcare professional can help individuals make informed decisions based on their specific needs and circumstances.
