Is It Safe to Have an Indoor Sauna in Your House?

Indoor saunas offer a relaxing haven with health benefits within the comfort of your home. As an intuitive consumer, you may wonder: is it safe to have an indoor sauna in your house? In this article, we will look into the safety aspects of indoor saunas, the pros and cons, and maintenance tips.

Health Benefits of Sauna

There's more to wellness than just what we put into our bodies. One way you can take care of your mental and physical health is by utilizing the benefits of a sauna. Here are some of them:

  • Improve cell generation (slow down aging)
  • Reduce stress
  • Lower inflammation
  • Ease sore tense muscles
  • Boost workout recovery

Is it safe to have an indoor sauna in your house?

Indoor saunas are generally safe. However, following safety guidelines such as maintaining a safe temperature, ensuring proper ventilation, staying hydrated, and limiting sauna sessions to 10-15 minutes is essential. If you have any underlying medical conditions, consult with a healthcare professional before using the sauna.

Safety Considerations Before Installing an Indoor Sauna

Sauna benefits are reasons enough to invest in an at-home sauna. But before you proceed, here are some safety precautions to look into.

Temperature regulation

Maintaining the appropriate temperature within your indoor sauna is crucial for comfort and safety. Excessive heat can lead to dehydration, overheating, and heatstroke. On the other hand, insufficient heat may not provide the desired benefits of the sauna experience. Find a balance.

Proper ventilation

Adequate ventilation is crucial for the circulation of fresh air within the sauna. Without it, the air inside can become stale and stuffy, potentially leading to discomfort and breathing difficulties. Look for saunas with built-in ventilation systems, or consider installing additional ventilation measures to maintain a healthy and refreshing environment.

Consult professionals

There are home saunas that are easy to install. But if you want to be sure everything works well, seeking the guidance of professionals or experts in sauna installation is highly recommended. Experts can provide valuable insights into the specific safety features of different indoor saunas, guaranteeing a secure and enjoyable sauna experience.

Potential Risks of Using Saunas and How to Mitigate Them

Be aware of possible hazards and implement appropriate precautions to guarantee a secure sauna session.

Dehydration and Overheating

The high temperatures in a sauna can cause excessive sweating, leading to dehydration if fluids are not replenished. Additionally, prolonged exposure to heat can result in overheating. Follow these tips to stay safe:

  • Stay hydrated: Drink plenty of water before, during, and after your sauna session to replenish lost fluids.
  • Limit session durations: Slowly build up your tolerance and start with shorter sauna sessions, gradually increasing the duration.
  • Listen to your body: Pay attention to any signs of discomfort, dizziness, or lightheadedness. If you experience these symptoms, exit the sauna immediately and cool down.

Safe Sauna Usage

Practicing safe sauna usage is essential for avoiding accidents and maximizing your experience. Consider the following precautions:

  • Follow manufacturer guidelines. Read and adhere to the instructions provided by the sauna manufacturer for proper usage and safety.
  • Use appropriate seating. Use the benches or seating provided in the sauna that are stable and secure.
  • Avoid alcohol and medications. Alcohol and certain drugs can affect your body's ability to regulate temperature. It's best to abstain from these substances before using a sauna.

Choosing an Indoor Home Sauna

Consider these factors in choosing the proper indoor sauna for your home:

Sauna type

There's a range of indoor saunas, including steam rooms, traditional saunas, and infrared saunas. Research each type and consider your preferences and specific health needs before deciding.

Available space

Measure the available space in your home to determine the size and design of the sauna that will fit comfortably. Consider whether you want a freestanding sauna or an enclosure that can be installed in an existing room.

Quality construction

Choose a home sauna made from durable materials that can withstand extreme temperatures. Look for features like solid wood construction and well-insulated walls.

Temperature control and settings

Check if the sauna offers precise temperature control and adjustable settings. This will allow you to customize your sauna experience based on your comfort level.

Ventilation and air circulation

Look for saunas with proper ventilation systems to maintain air quality and prevent stuffiness. Saunas with an oxygen ionization system can help purify the air.

Safety features

Choose saunas with safety features such as emergency shut-off switches, non-slip flooring, and tempered glass on doors. 

Energy efficiency

If you plan to use the sauna frequently, choose an energy-efficient one. Look for saunas with insulation features to minimize heat loss and energy consumption.

Read reviews and seek recommendations

Before making a final decision, read customer reviews and seek recommendations from trusted sources. Hearing about others' experiences can offer valuable insights into the quality and performance of different sauna models.

Are saunas a lot of maintenance?

Maintaining saunas is a simple task that doesn't require much effort. You should vacuum the floors and brush the benches and backrests at least once a week, ideally after each session, to keep your sauna in good condition. Once a month, wash bars with water and mild soap and leave them to dry for 24 hours.

Can bacteria survive in the sauna?

Bacteria can survive in saunas but are not inherently dirty or unsanitary. Keep your saunas clean and well-maintained to avoid undesirable bacterial growth. Look for saunas with an Oxygen Ionizer feature for purifying the air.

Can I sauna every day?

It is generally safe to use saunas daily, but staying hydrated during your sessions and limiting your time in the sauna to 15-20 minutes to avoid overheating is essential. People with certain health conditions should not use a sauna or at least consult their physician before using it.

Can you sweat out a virus in a sauna?

The long-held notion that you can “sweat out a virus" is scientifically unsound. Extended exposure to high temperatures in saunas that cause sweating can lead to dehydration, worsening existing cold symptoms. There is no scientific evidence to support sweating out a cold.

Do indoor saunas smell?

Saunas may smell bad if they are not adequately cleaned. Sweat, bacteria, dirt, mold, expired essential oils, wearing your day clothes, or improper ventilation can cause foul odors. All these smells can be avoided with proper preventative measures and a thorough, consistent cleaning regimen. The wood type can also contribute to the scent inside the sauna. The therapeutic aroma and deep red color of red cedar wood make it famous for saunas. If you want an odorless sauna, choose one made from hemlock wood.

Is it better to have a sauna inside or outside?

Both indoor and outdoor saunas have their pros and cons. Indoor saunas offer more privacy and convenience, while outdoor saunas provide a more natural and scenic environment. The choice depends on personal preference, budget, and space availability.

Is it expensive to run a home sauna? 

The cost of running an indoor home sauna depends on the type of sauna, the sauna heater, the size, and how often it is used. Saunas can increase your electric bill, but the amount depends on the sauna size and how often it is used. 

Where is the best place to put a home sauna?

The best place to put indoor saunas for home is in a dry, well-ventilated area with easy access to a water source and a drain. Locate a suitable location that will not interfere with your daily activities. Learn how to build an indoor sauna home with our Comprehensive Guide to Building Your DIY Sauna.
