Why Infrared Saunas Are Different

Unlike traditional saunas that heat the air around you to extreme temperatures (often 180-200°F), infrared saunas use light waves to heat your body directly. This means they operate at lower, more comfortable air temperatures (typically 120-170°F) while still producing deep, satisfying sweat.

The result is a sauna experience that many people find more comfortable for longer sessions, uses less energy, heats up faster, and can fit in more spaces since ventilation requirements are less demanding.

Types of Infrared Heaters

Far Infrared (FIR)

Far infrared is the most common and most studied type. Operating at wavelengths of 3-100 microns, far infrared penetrates the skin to heat your body's core, promoting sweating and circulation. Most affordable infrared saunas use far infrared heaters exclusively. Sun Home's Solstice line uses far infrared carbon fiber panels.

Near Infrared (NIR)

Near infrared operates at shorter wavelengths (0.7-1.4 microns) and penetrates deeper into tissue. It's associated with cellular energy production and skin health. Near infrared is what you find in red light therapy panels, and having it in your sauna adds another dimension of therapy.

Full-Spectrum

Full-spectrum saunas combine near, mid, and far infrared wavelengths for the most comprehensive experience. This is the premium option and what Sun Home's Equinox and Luminar lines offer. If budget allows, full-spectrum delivers the broadest range of potential benefits.

Wood Types Matter

The wood used in your sauna affects durability, appearance, aroma, and heat retention. Here are the most common options:

  • Canadian Red Cedar: The classic sauna wood. Naturally resistant to moisture and decay, aromatic, beautiful grain. Used in Sun Home's Solstice line.
  • Eucalyptus: Dense hardwood with natural antimicrobial properties. Contemporary look with a warm honey tone. Used in Sun Home's Equinox line.
  • Carbonized Cedar: Thermally treated cedar with increased density and weather resistance. Ideal for outdoor saunas. Used in Sun Home's Luminar line.
  • Hemlock/Basswood: Common in budget saunas. Lighter, less durable, and less aromatic than cedar or eucalyptus.

Sizing: How Many People?

Sauna capacity ratings are marketing numbers. Here's the reality:

  • 1-person saunas: Great for solo use, minimal space required. Best for dedicated personal wellness.
  • 2-person saunas: Comfortable for one, cozy for two. The most popular size for home use.
  • 3-person saunas: Comfortable for two with room to stretch, fits three if they're friendly.
  • 4-5 person saunas: Subtract one from the rating for comfortable seating. A "5-person" usually seats 4 adults comfortably.

When in doubt, go one size up from what you think you need. The extra space improves comfort dramatically.

EMF Safety: What to Look For

EMF (electromagnetic field) emissions are a legitimate consideration for infrared saunas since you sit in close proximity to electrical heating elements for extended periods.

Look for saunas with low-EMF certification, meaning emissions have been tested and verified below safety thresholds (typically under 3 milligauss at the body surface). All Sun Home Saunas are low-EMF certified.

Avoid saunas that don't publish EMF data or claim "zero EMF" - any electrical device produces some electromagnetic field. The goal is verified low levels, not impossible zero claims.

Electrical Requirements

Infrared saunas come in two electrical configurations:

  • 120V (Standard Outlet): Plugs into any household outlet. No electrician needed. Slower heat-up time. Best for 1-3 person saunas. Sun Home Solstice and Equinox offer 120V options.
  • 240V (Hardwired): Requires professional electrical installation ($500-$1,500). Faster heat-up, more consistent temperature. Required for larger saunas. Sun Home Luminar requires 240V.

Features Worth Having

  • Chromotherapy: LED color therapy adds visual relaxation to your sessions.
  • Bluetooth Speakers: Stream music or meditation guides for enhanced relaxation.
  • Mobile App Control: Pre-heat your sauna remotely and set schedules. A genuine convenience feature.
  • Digital Controls: Precise temperature setting with clear displays.

Skip features like ionizers, salt walls, and "detox programs" - these are marketing additions with minimal evidence behind them.

What to Spend

Quality home infrared saunas fall into three tiers:

  • Budget ($1,000-$3,000): Basic construction, far infrared only, shorter warranties. Functional but may lack durability.
  • Mid-Range ($3,000-$6,000): Better wood, low-EMF heaters, more features. The Sun Home Solstice line sits here.
  • Premium ($6,000-$10,000+): Full-spectrum, premium materials, smart features, long warranties. Sun Home Equinox and Luminar are in this range.
