How to Safely Use Your Sauna at Any Temperature

No matter which sauna type you choose, following safety guidelines ensures you get maximum benefits while minimizing risks.

Hydration Is Essential

Drink 16 to 20 ounces of water before your session and rehydrate immediately afterward. A study in the Scandinavian Journal of Medicine & Science in Sports confirmed that dehydration can occur rapidly in high-heat environments. Avoid caffeine and alcohol before sauna use, as both can impair your body's ability to regulate temperature and fluid balance.

Start Low and Go Slow

If you're new to sauna bathing, begin with shorter sessions (10 to 15 minutes) at the lower end of your sauna's temperature range. The Cleveland Clinic recommends gradually increasing both duration and temperature as your body acclimates. Listen to your body's signals—there's no prize for toughing it out.

Cool Down Properly

After your session, allow your body to cool gradually. Step out and sit in a room-temperature environment for a few minutes before taking a lukewarm or cool shower. Some sauna enthusiasts practice contrast therapy—alternating between hot sauna and cold plunge—but this should only be attempted once you're experienced and have discussed it with your healthcare provider.

Know Your Limits

Sessions should generally last 15 to 30 minutes, depending on temperature and your experience level. Exit immediately if you feel dizzy, nauseous, short of breath, or uncomfortable. Pushing through warning signs can lead to heat exhaustion or worse.

Who Should Be Cautious with High Sauna Temperatures?

While saunas are safe for most healthy adults, certain conditions require extra caution or medical clearance:

• Cardiovascular disease (especially unstable angina or recent heart attack)
• Pregnancy
• Uncontrolled high or low blood pressure
• Recent surgery or open wounds
• History of fainting or heat intolerance
• Certain neurological conditions

The American Heart Association and Mayo Clinic both emphasize that individuals with heart conditions should consult their physician before beginning regular sauna use. Heat stress can exacerbate certain medical conditions, so personalized guidance is essential.

Never use a sauna when dehydrated, under the influence of alcohol, or feeling ill.

Choosing the Right Temperature for Your Goals

Your ideal sauna temperature depends on what you're hoping to achieve and your personal heat tolerance.

For Cardiovascular Conditioning and Intense Detoxification

If you want the full-intensity traditional experience with maximum cardiovascular challenge, aim for 150°F to 190°F in a traditional sauna. Research suggests that higher temperatures, when used safely and regularly, correlate with the most significant heart health benefits.

For Pain Relief and Muscle Recovery

Athletes and those with chronic pain often prefer infrared saunas at 120°F to 140°F. The deep-penetrating heat targets muscles and joints without the extreme air temperature, allowing for longer, more comfortable sessions.

For Relaxation and Stress Reduction

Both sauna types effectively reduce stress, so choose based on your heat preference. Traditional saunas offer a more intense, ritualistic experience, while infrared provides a gentler, longer session that many find easier to incorporate into evening routines.

For Beginners

Start with infrared or the lower temperature range of traditional saunas (around 150°F). As you become accustomed to the heat, you can experiment with higher temperatures and longer sessions.

Enhancing Your Sauna Experience

Once you've mastered the basics, these additions can take your sessions to the next level:

Aromatherapy: Add a few drops of eucalyptus or lavender essential oil to water and splash it on the sauna stones (traditional saunas only). The steam carries the scent, creating a spa-like atmosphere.

Meditation and Breathwork: The quiet, warm environment is perfect for mindfulness practice. Deep breathing exercises can enhance the stress-relief benefits.

Cold Therapy: Experienced sauna users often alternate between hot sauna sessions and cold showers or ice baths. This contrast therapy may boost circulation, immunity, and recovery, though it's not for beginners.

Bring a Cold Towel: Draping a cool, damp towel around your neck can help regulate body temperature during longer sessions.

The Science Behind Sauna Temperatures

Understanding the research helps contextualize why temperature matters so much. A landmark study published in JAMA Internal Medicine followed over 2,300 Finnish men for more than 20 years. Those who used saunas four to seven times per week had a 66% lower risk of dementia compared to those who used saunas once weekly. Importantly, the benefits increased with both frequency and temperature intensity.

However, it's worth noting that not all health claims have equal scientific backing. While sauna use clearly benefits cardiovascular health and stress reduction, claims about "detoxification" are more nuanced. Harvard Health points out that the body's primary detox organs are the liver and kidneys, not sweat glands. Sweating does eliminate some heavy metals and chemicals, but the quantities are minimal compared to what your organs process daily.

Frequently Asked Questions

What temperature is too hot for a sauna?

For traditional saunas, most experts recommend staying below 195°F (90°C). Temperatures above this can increase the risk of burns, dizziness, and heat exhaustion. For infrared saunas, exceeding 150°F is unnecessary and may reduce comfort without adding benefits.

How long should you stay in a sauna at different temperatures?

In a traditional sauna at 170°F to 190°F, limit sessions to 10 to 20 minutes. In an infrared sauna at 120°F to 140°F, you can comfortably stay 20 to 40 minutes. Always prioritize how you feel over hitting a specific time goal.

Are infrared saunas as effective as traditional saunas?

Both types offer significant health benefits, but they work differently. Traditional saunas provide more intense cardiovascular stress similar to moderate exercise. Infrared saunas excel at deep tissue heat therapy and pain relief. Neither is objectively "better"—it depends on your goals and preferences.

Can you use a sauna if you're pregnant or have high blood pressure?

Pregnant women and people with uncontrolled high blood pressure should avoid saunas or get explicit medical clearance first. The heat can affect blood pressure and fetal development. Always consult your healthcare provider if you have any medical concerns.

How does sauna temperature affect recovery for athletes?

Heat therapy aids muscle recovery by increasing blood flow to damaged tissues and reducing inflammation. Many athletes prefer infrared saunas for recovery because the lower air temperature allows longer sessions focused on deep tissue heat rather than cardiovascular stress.

What is contrast therapy, and is it safe?

Contrast therapy involves alternating between hot sauna sessions and cold water immersion. This technique may enhance circulation, reduce muscle soreness, and boost immunity. However, it places additional stress on the cardiovascular system and should only be attempted by healthy individuals experienced with sauna use.

How often should you use a sauna for health benefits?

Research suggests using a sauna three to seven times per week provides optimal cardiovascular benefits. However, even once or twice weekly can improve relaxation and muscle recovery. Consistency matters more than intensity.

Is there a difference between sweating in an infrared and a traditional sauna?

Yes. Traditional saunas trigger profuse sweating quickly due to high air temperature. Infrared saunas produce similar sweat volume but more gradually, as the heat penetrates from within rather than heating the air around you. Both are effective for the benefits associated with sweating.

Does using essential oils in the sauna improve health effects?

While essential oils can enhance the sensory experience and promote relaxation through aromatherapy, there's limited scientific evidence that they provide additional physical health benefits beyond what the heat itself offers. They're a nice addition but not necessary for therapeutic results.

What's the best way to cool down after a sauna session?

Exit the sauna and sit in a room-temperature space for 5 to 10 minutes, allowing your heart rate and body temperature to gradually normalize. Then take a lukewarm to cool shower. Avoid jumping into cold water immediately unless you're experienced with contrast therapy and have medical clearance.

Final Thoughts: Finding Your Perfect Sauna Temperature

The right sauna temperature is the one that matches your body, your goals, and your lifestyle. Traditional saunas offer intense heat and rapid cardiovascular benefits, while infrared saunas provide gentle, deep-tissue therapy with longer session comfort.

Start conservatively, listen to your body, and adjust based on how you feel during and after sessions. Whether you prefer the 180°F intensity of a Finnish sauna or the comfortable 130°F warmth of an infrared cabin, consistency is what matters most for long-term health benefits.
