Thinking About Saunas? Here’s What You Need to Know Before You Jump In

Saunas aren’t just a luxury spa thing anymore — they’re becoming a regular part of many Kiwis’ health routines. Whether you’re looking to support heart health, ease muscle tension, improve sleep, or just find a moment of calm in a busy week, saunas can offer real benefits. And yes, the science backs it up.

If you’re considering adding sauna sessions to your health plan, here’s everything you need to know — including the types available in NZ, where to go, what it costs, and how often to use them.

What Types of Saunas Are Available in NZ?

There are a few main types you’ll come across:

1. Traditional Finnish Sauna (Dry Heat)

  • Uses heated stones to create dry heat (80–100°C)
  • Can be wood-fired or electric
  • Often found in gyms, spas, or home setups
  • Home units start around $4,000–$10,000 depending on size and build

2. Infrared Sauna

  • Uses infrared light to heat the body directly (lower temp: 45–60°C)
  • Popular for people who prefer gentler heat
  • Often found in wellness clinics or as portable home units
  • Home units range from $2,000–$6,000

3. Steam Room (Wet Sauna)

  • Uses steam to create high humidity and moderate heat
  • Great for respiratory health
  • Found in spas, pools, and some gyms
  • Less common for home use due to plumbing needs

Where Can You Go for a One-Off Sauna in NZ?

If you’re not ready to commit to a home sauna, there are plenty of places to try one out:

  • Gyms: Many commercial gyms (like Les Mills or CityFitness) have traditional saunas included in membership
  • Spas and wellness centres: Infrared and steam saunas available for casual bookings
  • Float and recovery studios: Often offer infrared sauna sessions alongside massage or float therapy
  • Hot pools and thermal resorts: Places like Polynesian Spa (Rotorua) or Hanmer Springs offer sauna access with entry

Expect to pay around $20–$40 per session, depending on location and type.

What Are the Health Benefits?

Saunas aren’t just about sweating — they’re about supporting your body in multiple ways. Here’s what the research shows:

Cardiovascular Health

  • Regular sauna use improves circulation and lowers blood pressure
  • Finnish studies show people who sauna 4–7 times/week have up to 50% lower risk of heart disease

Detoxification

  • Deep sweating helps eliminate toxins like heavy metals and chemicals
  • Supports liver and kidney function by reducing their load

Respiratory Health

  • Steam and heat can open airways, reduce mucus, and improve lung function
  • Helpful for asthma, chronic bronchitis, and sinus congestion

Mental Health

  • Heat triggers endorphin release — your body’s natural feel-good chemicals
  • Reduces stress, anxiety, and promotes better sleep

Muscle Recovery and Pain Relief

  • Heat relaxes muscles, reduces soreness, and improves joint mobility
  • Great post-workout or for chronic pain conditions like arthritis

Skin Health

  • Sweating helps cleanse pores and improve skin tone
  • May support collagen production and skin elasticity

How Often Should You Sauna?

To get the most benefit, consistency is key.

  • 2–3 times per week is a great starting point
  • 4–7 times per week is ideal for cardiovascular and mental health benefits (based on Finnish studies)
  • Sessions can be 15–30 minutes, depending on heat tolerance and type

Just like exercise, it’s about building a habit — not going all in once and burning out.

Final Thoughts: Sauna as Part of a Bigger Health Plan

Saunas can be a powerful tool — but they’re not a standalone fix. Think of them as part of a broader lifestyle approach that includes, nourishing food, regular movement, good sleep and stress management.  And they are a great to have some “me” time, prioritising yourself and your health above other stressors in your life.
