The benefits of sauna go past relaxation alone. For centuries, cultures around the world have relied on heat therapy to support physical recovery, mental clarity, and long-term health. Today, saunas have become a wellness tool backed by growing scientific interest.
In this article, we’ll explore the science, types, and top health benefits of sauna use, plus who should avoid it and how to integrate it into a balanced wellness routine.
Let’s begin!
What Is a Sauna?
A sauna is a small heated room designed to raise body temperature and induce sweating. Traditional saunas utilize dry heat, whereas modern variations may employ infrared technology or steam.
Sessions typically last between 10 and 30 minutes, depending on temperature, experience level, and individual tolerance.
The primary goal of a sauna is to expose the body to controlled heat, which triggers physiological responses such as increased heart rate, improved circulation, and muscle relaxation.
What Are the Different Types of Saunas?
The different types of saunas are defined by how they produce heat and humidity. Each offers slightly different sensations and potential benefits. Let’s see:
1- Traditional (Dry) Sauna
The traditional dry sauna uses heated stones or electric heaters to warm the air, typically between 160°F and 200°F (70–95°C). Humidity remains low unless water is poured over the stones.
2- Infrared Sauna
The infrared sauna uses infrared light to heat the body directly rather than warming the air. Temperatures are lower (120–150°F), making it more tolerable for people sensitive to intense heat.
3- Wood-Burning Sauna
A traditional option typically found in rural or outdoor settings. Heat is generated by burning wood, offering a more rustic experience.
4- Steam Sauna (Steam Room)
The steam sauna uses moist heat with nearly 100% humidity and lower temperatures (around 110–120°F). Often preferred for respiratory comfort.
📌 Each sauna type supports relaxation and circulation, but infrared saunas are often favored for muscle recovery and accessibility due to their lower heat intensity. |
Sauna vs. Steam Room: What Is the Difference?
The difference between a sauna and a steam room is primarily humidity and heat delivery. Saunas use dry or infrared heat with low humidity, while steam rooms rely on moist heat with high humidity.
Saunas tend to feel hotter and are often preferred for muscle relaxation and cardiovascular stimulation. Steam rooms may feel gentler on joints and are commonly associated with respiratory comfort and skin hydration.
Research shows that the heat from a sauna can boost heart health, help maintain healthy blood pressure, relieve pain, and soothe sore muscles. - Cleveland Clinic Health System
Top 5 Health Benefits of Using a Sauna
#1 Improved Muscle Recovery
Heat increases blood flow to muscles, helping deliver oxygen and nutrients while reducing stiffness and soreness. This makes sauna use especially beneficial after strength training or intense workouts.
#2 Stress Reduction and Relaxation
Sauna sessions promote the release of endorphins and activate the parasympathetic nervous system, helping lower stress levels and improve mood.
#3 Cardiovascular Support
Regular sauna use has been associated with increased heart rate similar to moderate exercise. This may support heart health by improving circulation and vascular function.
#4 Joint Mobility and Pain Relief
Heat relaxes connective tissues and may reduce joint stiffness, making saunas helpful for individuals with chronic tension or mobility limitations.
#5 Enhanced Circulation and Detoxification
Sweating helps the body regulate temperature and may assist in eliminating small amounts of waste products, while improved circulation supports overall tissue health.
Together, these effects explain why the benefits of sauna use extend beyond relaxation and into long-term wellness support.
How to Use a Sauna: Best Practices for Safe and Effective Results
To use a sauna, start with short sessions and gradually increase duration as your tolerance improves. Most people benefit from 10–20 minutes per session, 2–4 times per week.
Best practices include:
Hydrating before and after your session
Showering before entering the sauna
Sitting or lying comfortably, avoiding direct contact with heaters
Exiting immediately if you feel dizzy, nauseous, or uncomfortable
Cooling down gradually afterward
📌 Consistency matters more than intensity. Short, regular sessions provide more sustainable benefits than infrequent, prolonged exposure. |
Who Should Avoid Saunas?
Saunas are not suitable for everyone. You should avoid using a sauna if you:
Are pregnant and have not received medical clearance
Have uncontrolled high or low blood pressure
Have a heart condition without approval from a healthcare provider
Are dehydrated or currently experiencing a fever or illness
Are sensitive to heat or prone to dizziness or fainting
Are under the influence of alcohol or other substances
If you’re unsure whether sauna use is safe for you, it’s best to consult a healthcare professional before starting.
Heat exposure and sauna bathing have been shown to improve multiple markers of cardiometabolic health, potentially acting as hormetic stressors at the cellular level. - Henderson et al., 2021

Should I Use a Sauna After a Workout?
Yes, you can use a sauna after a workout, as it may help with muscle relaxation and recovery, provided you rehydrate and allow your body to cool down afterward.
