❤️ Sauna & Heart Health

Cardiovascular benefits are one of the most studied aspects of sauna use — especially in Finland, where sauna is less trendy and more just your average Tuesday.

What Happens Inside Your Body

In the sauna:

• heart rate rises to ~100–150 bpm

• blood vessels dilate

• circulation improves

It’s similar to light-to-moderate exercise (Hannuksela & Ellahham, Am J Med, 2001).

And the big headline? The famous Finnish cohort studies led by Dr. Jari Laukkanen (University of Eastern Finland) followed thousands of people over decades. They found that frequent sauna use was associated with:

• lower risk of fatal heart disease

• fewer sudden cardiac deaths

• reduced all-cause mortality

(Laukkanen et al., JAMA Internal Medicine, 2015)

Important note: association ≠ magic cure. But it’s meaningful.

Why It Doesn’t Feel “Stressful”

Even though your heart works harder, the context is calming — warmth, stillness, predictability.

So you get cardio benefits without staring at an exercise bike wondering why time has stopped moving.

*Make Sure to Check With Your Doctor If…

• you have unstable heart conditions

• recent heart attack

• severe heart failure

• uncontrolled high/low blood pressure

• certain respiratory issues

• kidney disease

• fainting episodes

• you’ve been told to avoid heat

  
  

Frequency That Seems Helpful

Many studies looked at:

• 2–7 sessions/week

• ~10–20 minutes each

Consistency beats heroics.

Sauna isn’t a miracle. It’s a supportive, evidence-backed habit wrapped in wood paneling.
