Sauna for Beginners

Getting Started · 7 min read

New to sauna? This guide covers everything you need to know — from choosing the right type of sauna to your first session, what to expect, and how to build a sustainable habit.

Key Takeaways

Start with 10-15 minutes at a moderate temperature (70-80°C) and build up.
Traditional Finnish and infrared saunas are the two most common types.
Hydrate well before, during, and after your session.
Aim for 2-3 sessions per week as a beginner before increasing frequency.
Listen to your body — dizziness or nausea means it’s time to get out.

Types of Saunas

There are several types of saunas, but two dominate the longevity conversation. Understanding the differences will help you choose the right fit.

Traditional Finnish sauna: heats air to 80-100°C using rocks and a heater. High heat, low to moderate humidity.
Infrared sauna: uses infrared panels to heat your body directly at 50-65°C. Lower air temperature, deeper tissue penetration.
Steam room: high humidity, lower temperature (40-50°C). Less studied for longevity but good for respiratory health.
Barrel sauna / outdoor sauna: a Finnish-style sauna in a barrel or cabin format, often used at home.

Your First Session

Don’t overthink your first sauna experience. The goal is to get comfortable with heat exposure and learn how your body responds. Enter the sauna hydrated, sit on a lower bench (it’s cooler closer to the floor), and stay for 10-15 minutes. If you feel dizzy, lightheaded, or nauseous, step out immediately. Cool down gradually — a lukewarm shower works well. You don’t need to push through discomfort as a beginner.

Building a Routine

Consistency matters more than intensity. Start with 2-3 sessions per week and focus on showing up regularly rather than pushing for extreme temperatures or durations. A good beginner progression looks like this:

Weeks 1-2: 10-15 minutes at 70-80°C, 2x per week
Weeks 3-4: 15-20 minutes at 75-85°C, 3x per week
Month 2+: 15-20 minutes at 80-100°C, 3-4x per week
Advanced: multiple rounds with cold exposure between sessions

What to Bring & Wear

Keep it simple. Most public saunas provide towels, but bring your own water bottle. In Finland, saunas are used naked; in most other cultures, a swimsuit or towel wrap is standard. Always sit on a towel for hygiene. Remove jewelry — metal gets hot. Leave electronics outside.

Hydration & Recovery

You’ll lose a significant amount of water and electrolytes through sweat during a sauna session. Drink at least 500ml of water before your session and continue hydrating afterward. Adding a pinch of sea salt or an electrolyte mix to your water helps replace lost sodium, potassium, and magnesium. Don’t drink alcohol before or during sauna use — it increases dehydration and cardiac risk.

Common Beginner Mistakes

Most beginners make the same handful of errors. Avoiding these will make your experience safer and more enjoyable.

Going too hot, too long on the first session
Not hydrating before entering the sauna
Eating a large meal immediately before (wait at least 1 hour)
Using a sauna while hungover or after drinking alcohol
Comparing yourself to experienced sauna users — build gradually

The Bottom Line

Starting a sauna practice is simple: begin at a comfortable temperature, keep sessions short, hydrate well, and build consistency over time. Most people notice improved sleep and mood within the first few weeks.
