Why Buy an Outdoor Sauna?
For individuals who have experienced the therapeutic benefits of saunas in communal settings and possess available outdoor space, an outdoor sauna can be a worthwhile investment in personal health. Dr. Mikhael highlights research indicating significant health advantages associated with regular sauna use, particularly in the management of cardiovascular conditions like high blood pressure and heart disease, as well as relief from acute and chronic pain and neurological disorders.
The logistical complexities of installing an indoor sauna, such as space requirements, ventilation, and insulation, can be considerable. Outdoor saunas often present a more straightforward installation process. Furthermore, they offer the distinct advantage of proximity to nature. Dr. Sharma notes, "One big bonus of outdoor saunas specifically is they exist outdoors. There is a problem in our society labeled Nature Deficit Disorder, which means we aren’t spending enough time outside. There are many proven benefits of being outdoors, and these saunas allow you to combine them with the potential benefits of heat therapy." This integration of natural surroundings with therapeutic heat enhances the overall wellness experience.
How to Use an Outdoor Sauna
Once your outdoor sauna is installed, operation varies by model, with temperature control typically managed through manual dials, Bluetooth-enabled apps, or touchscreens. Heating is provided by either electric sauna heaters or wood-burning stoves. Some models offer advanced timer functions, allowing for pre-heating up to 36 hours in advance. The process of using the sauna is simple: enter the pre-heated space and relax.
For optimal benefits, Dr. Mikhael recommends "Two to three 15- to 25-minute sessions per week." He elaborates, "After 15 to 25 minutes, people can benefit the most without feeling like they’re getting dehydrated or dizzy." During sessions, engaging in activities like reading, listening to music, or conversing with a companion can enhance the experience. Crucially, maintaining hydration is paramount. "You want to ensure you’re hydrated before and after," advises Dr. Sharma. "A sauna induces a lot of sweating, so you can get dehydrated very easily." Post-sauna hydration, especially for heavy sweaters, may be enhanced with electrolyte supplements.
The Benefits of an Outdoor Sauna
Earric Lee emphasizes the synergistic effects of combining exercise with sauna bathing. "We found not only is a combination of exercise and sauna bathing stronger in its effects, but many cardiovascular benefits, like lower blood pressure, were sustained for a longer period afterward." This suggests that incorporating sauna sessions into a post-workout routine can amplify and prolong the positive physiological responses to exercise.
What to Look for in an Outdoor Sauna
Power
The operational requirements of an outdoor sauna vary. Most electric models necessitate a power source for heaters and lighting. Wood-burning saunas offer a more independent solution, particularly if they lack electrical lighting. For environmentally conscious consumers, solar-powered options are emerging, though a battery backup is generally recommended.
Portability
Due to their size and construction, most outdoor saunas are not easily portable. It is advisable to consider an outdoor sauna purchase for a permanent residence rather than a temporary living situation. While a constructed sauna can be relocated, it typically requires professional equipment. For a more mobile solution, portable tent saunas are available at a significantly lower price point.
Cost
The outdoor saunas featured in this guide range in price from approximately $1,599 to $9,799. Generally, lower-priced models offer efficient heating, while higher-end options provide greater capacity, more advanced temperature control, enhanced comfort features, and superior materials.
Outdoor Sauna Accessories
Many outdoor saunas offer optional accessories to enhance the user experience. These can include outdoor showers, cold plunge tubs (such as The Plunge), and wooden recliners. While these additions can elevate comfort and enjoyment, they are not essential for basic sauna functionality.
Final Thoughts
While many wellness trends prove ephemeral, sauna bathing has maintained its status as a cultural cornerstone in Scandinavian life for centuries, offering demonstrable and lasting benefits for well-being. Experts concur that consistent sauna use can alleviate muscle soreness and manage chronic pain effectively.
For those who have integrated heat therapy into their wellness routines and have the available space and budget, an outdoor sauna represents a significant and beneficial investment. However, as with any major health-related purchase, consulting a physician is strongly advised before acquiring an outdoor sauna or embarking on a new sauna regimen, particularly for individuals with pre-existing severe cardiovascular or respiratory conditions.
