How Long Should You Stay in a Sauna?

Saunas have long been cherished as places for relaxation, socializing, and health enhancement. They offer benefits like improved cardiovascular health, detoxification, and muscle relaxation. But how long should you stay in one to maximize benefits without compromising your health? Here’s everything you need to know for a safe and rewarding sauna experience.

Finding Your Ideal Sauna Time

If you’re new to sauna bathing, start with short sessions of about 5-10 minutes to allow your body to adjust to the heat. Many experts, including the American Sauna Society, recommend that beginners limit their time to a maximum of 20 minutes per session. Seasoned sauna users may be able to enjoy up to 30 minutes, but it’s essential to listen to your body. Once you start feeling uncomfortably hot or fatigued, it’s time to step out and cool off.

For those interested in longer sessions, it’s a good idea to break up your time by taking cool-down breaks in between. Experienced sauna enthusiasts, particularly in Finland, where the sauna culture originated, often stay longer by leaving the room periodically, keeping their session enjoyable and safe.

The Benefits of Sauna Use

Spending time in a sauna can positively affect both physical and mental well-being. Here are a few of the most widely recognized health benefits:

1. Cardiovascular Health: Research has shown that sauna use may help improve heart function and blood pressure, especially when combined with regular exercise.
2. Reduced Stroke Risk: Frequent sauna use has been linked to a lower risk of stroke in older adults.
3. Improved Mental Health: Sauna sessions can reduce stress and anxiety levels, primarily by lowering cortisol levels and boosting endorphin release, which may enhance mood and relaxation.
4. Reduced Muscle Soreness: Some studies suggest that infrared saunas, in particular, can help ease post-workout muscle pain.
5. Lowered Dementia Risk: In a Finnish study, frequent sauna use was associated with a reduced risk of dementia and Alzheimer’s disease.

While these benefits make a sauna session enticing, the key to reaping them lies in moderation.

Risks of Overstaying in a Sauna

Saunas offer numerous benefits, but overuse can lead to health risks. Spending too much time in a sauna increases the likelihood of:

• Dehydration: Excessive sweating can lead to fluid loss and dehydration, resulting in dizziness, fatigue, and even muscle cramps.
• Hyperthermia: When body temperature rises too high, it can lead to heat exhaustion or, in extreme cases, heat stroke.
• Skin Problems: Overexposure to heat may dry out the skin, potentially causing irritation and worsening existing skin conditions like eczema or psoriasis.
• Heart Issues: Prolonged heat exposure can strain the heart, increasing the risk of arrhythmias, especially for individuals with existing heart conditions.

How Long to Stay in a Sauna for Different Health Goals

The ideal sauna time varies based on the health benefits you’re looking to achieve:

• Detoxification: Aiming for around 15-20 minutes can provide enough time for your body to begin sweating out toxins effectively.
• Relaxation and Stress Relief: Spending 10-15 minutes in a sauna may be enough to unwind, helping to reduce stress levels without pushing your limits.
• Post-Workout Recovery: For easing muscle soreness, try 10-20 minutes, allowing enough time for heat to relax the muscles without risking dehydration.

Be mindful that these times may need to be adjusted based on your comfort and overall health.

Factors Influencing Sauna Duration

Your ideal sauna session length depends on several factors:

1. Type of Sauna: Traditional saunas with higher temperatures typically call for shorter sessions (10-15 minutes). Infrared saunas operate at lower temperatures, so sessions can be safely extended to 20-45 minutes. Steam rooms are humid and hot, making them better suited to 10-20 minute sessions.

2. Age: Older adults and young children should spend less time in saunas due to their bodies’ lower tolerance for high heat and dehydration risks.

3. Health Conditions: Individuals with specific health conditions, like high blood pressure, heart disease, or respiratory issues, should consult a healthcare professional before using a sauna.

4. Personal Comfort: Above all, listen to your body. If you start feeling lightheaded, nauseous, or uncomfortably hot, it’s time to exit the sauna.

Tips for Safe Sauna Use

To enjoy a safe and rewarding sauna experience, keep these tips in mind:

• Stay Hydrated: Drink water before, during, and after your session to replenish lost fluids.
• Avoid Alcohol: Drinking alcohol before or during sauna use can increase dehydration and interfere with your body’s cooling process.
• Dress Appropriately: Wearing a towel or loose clothing allows for better heat circulation and helps prevent overheating.
• Monitor Your Time: Aim to spend between 10-20 minutes in a sauna. Beginners should start with shorter sessions, gradually increasing their time.
• Cool Down Gradually: After leaving the sauna, give your body time to adjust by sitting in a cooler area or taking a lukewarm shower.

Sauna Use FAQs

Is It Safe to Use a Sauna Daily? Yes, daily sauna use is safe for most people, provided that sessions are no longer than 20 minutes and you stay hydrated.

What Happens if You Stay in a Sauna Too Long? Overstaying in a sauna can lead to dehydration, dizziness, nausea, and, in severe cases, heat stroke. Always listen to your body and leave the sauna if you feel uncomfortable.

The Takeaway

Saunas offer numerous health benefits, from relaxation to cardiovascular improvement, as long as they’re used in moderation. For most people, 10-20 minutes per session is ideal, but ultimately, it’s essential to pay attention to your body’s signals.
