How Long to Sit in a Sauna Before Workout

Using a sauna before your workout can be an excellent way to activate your muscles, improve flexibility, and boost mental focus. But to maximize benefits—and avoid overexertion—it’s important to follow proper timing and safety protocols.

What Happens When You Sauna Before Exercise?

When you expose your body to high heat for a short time, your blood vessels dilate, heart rate rises slightly, and blood flow increases to your extremities. This mimics some of the physiological effects of a warm-up.

Here are the benefits:

• Improved blood flow to muscles

• Enhanced flexibility and range of motion

• Better mental preparation and reduced stress

• Reduced chance of strains and pulls

Ideal Time to Spend in a Sauna Before a Workout

Recommended Duration: 10 to 15 minutes

This range is ideal for most people. It warms your body without leading to dehydration or fatigue, which could impair your actual training performance.

• Less than 10 minutes: May not provide a meaningful warm-up effect.

• More than 15 minutes: Increases risk of overheating or sapping energy before your session.

For most fitness routines—whether weightlifting, running, or calisthenics—staying within that 10–15-minute window is best.

Tip: Always hydrate before and after your sauna session. If you're light-headed, cut it short.

Best Type of Sauna for Pre-Workout Use

Not all saunas are created equal when it comes to warming up for a workout:

• Traditional Saunas: Use dry heat and work quickly to warm your muscles.

• Infrared Saunas: Lower temperatures but penetrate deeper into tissue. Great for gentler warm-ups.

• Hybrid Saunas: Combine both for added versatility depending on your needs.

Choosing the right type depends on your workout style and how your body reacts to heat. Need help deciding? Use our Sauna Selector tool to find the best sauna for your space.

Timing Around Workouts

• Before strength training or cardio: Sit in the sauna 10–15 minutes, towel off, rehydrate, then begin your workout within 10–20 minutes.

• Before yoga or stretching: Sauna use enhances flexibility. Pairing the two can reduce the chance of injury.

• Avoid doubling up: If you also use the sauna post-workout, limit both sessions to avoid overexposure.

Warnings and Safety Tips

• Don’t enter the sauna dehydrated

• Skip sauna sessions if you’ve consumed alcohol or feel ill

• Never exceed 15 minutes if it's your pre-workout routine

• Start with 5–8 minutes if you're new to heat exposure

Yes, but use a sauna before your warm-up and the Cold Plunge after your session to enhance recovery.
