The Healing Power of Saunas

Stress Reduction and Improved Mental Health

One of the primary benefits of regular sauna use is stress reduction and enhanced mental well-being. A study published in the “Journal of Alternative and Complementary Medicine” found that sauna bathing significantly decreased levels of the stress hormone cortisol in participants, leading to reduced perceived stress and increased feelings of relaxation and tranquility. Saunas provide a sanctuary for both the body and mind, allowing individuals to disconnect from the outside world and find solace in the soothing heat.

Detoxification and Improved Skin Health

Sweating is the body’s natural mechanism for eliminating toxins, and saunas amplify this process. As you sweat in a sauna, your pores open, and impurities are expelled from your skin. A study published in the “Archives of Environmental Contamination and Toxicology” discovered that saunas help eliminate a range of harmful substances, including heavy metals and environmental chemicals, from the body. The result is not only improved detoxification but also healthier, clearer skin.

Cardiovascular Health

Regular sauna sessions have been linked to a reduced risk of cardiovascular diseases. A study conducted in Finland, where saunas are an integral part of the culture, revealed that frequent sauna use is associated with a lower risk of heart disease, stroke, and all-cause mortality[^3^]. Sauna-induced heat leads to the dilation of blood vessels, reducing blood pressure and improving overall cardiovascular function. This effect mirrors the benefits of exercise, making saunas an excellent addition to a heart-healthy lifestyle.

Muscle and Joint Pain Relief

The heat and steam in saunas can provide profound relief for muscle and joint pain. The increased blood flow and circulation stimulated by sauna sessions can alleviate discomfort and promote healing. A study published in the “Annals of Clinical Research” highlighted the positive impact of sauna therapy on patients with chronic pain conditions, including fibromyalgia and rheumatoid arthritis[^4^]. Regular sauna use may be a valuable complementary therapy for individuals suffering from chronic pain.

Weight Loss and Calorie Burn

A sauna session will not only reduce water weight, but it can also potentially increase caloric burn. In a 2019 research study centered on sedentary and overweight individuals assigned male at birth, it was discovered that undergoing four 10-minute sauna sessions led to notable alterations in various physiological indicators. These changes encompassed modifications in heart rate, energy expenditure, body mass index (BMI), and body surface area.

The study’s findings revealed that participants experienced a reduction of approximately 0.65 kilograms (kg) in body fluids as a result of the sauna sessions. Moreover, it was observed that individuals with greater body mass, body area, body fat content, and muscle mass exhibited comparatively higher calorie expenditure during their sauna bathing sessions.

8. Power Requirements

Often overlooked, It’s important to consider the power usage your sauna will require. Some saunas operate on a standard 120V, 15-amp circuit, which can be conveniently plugged into any typical household outlet. On the other end of the spectrum, larger units may require as much as 240V, drawing 30 amps.

What to consider:

  • Steam & Electric: Both steam saunas and electric dry saunas typically rely on a 20-30 amp 220V power supply. 

  • Infrared: Many infrared saunas are designed to function efficiently with a 15-amp, 110V setup, making them an attractive option for many users. Not needing to upgrade your electrical system is often a significant selling point, depending on your specific needs and preferences.

Many people wonder whether the lower electrical requirements of infrared saunas affect their performance. In fact, quite the opposite is often true. Infrared saunas tend to heat up faster and require shorter preheat time.

9. Warranty

A good warranty provides peace of mind. Look for saunas backed by a comprehensive warranty that covers both the sauna’s construction and heating elements.

10. Budget & Pricepoint

Your budget range will impact the size of your sauna as well as the amount of special features. Determine the minimum size for your sauna and must-have features before committing to a budget range. This will ensure you purchase a sauna that complements your lifestyle and will stand the test of time.

Final Thoughts

Saunas offer an array of health benefits that are supported by scientific research. From stress reduction and detoxification to cardiovascular improvements and pain relief, regular sauna use can be a valuable addition to your wellness routine. When choosing a sauna, carefully assess your preferences, needs, and available space to find the perfect fit for your home. Whether you opt for a traditional Finnish sauna, an infrared sauna, or a steam sauna, you can look forward to a wealth of physical and mental health benefits that have been cherished for generations.
