The decision in one paragraph
Sauna blankets are cheaper, more portable, and deliver more intense heat — but they're claustrophobic and limit session length to 20–25 minutes. Sauna tents cost a bit more, take more floor space, and have less intense heat — but they're comfortable for 30–45 minute sessions because your head stays outside the heated chamber. Most regular users end up preferring tents; budget-conscious or space-constrained users prefer blankets.
Side-by-side

| Max temperature | 160–175°F | 140–150°F |
| Head position | Inside (with face hole) | Outside (head pops out top) |
| Max comfortable session | 20–25 min | 30–45 min |
| Claustrophobia risk | High (some users can't tolerate) | Low (head free) |
| Storage footprint | Folds to yoga mat size | Folds to large duffel size |
| Setup footprint | 6'×2' (yoga mat area) | 3'×3'×4' (chair + tent) |
| Read/watch TV during use | Difficult (arms inside) | Easy (head and arms free) |
| EMF exposure | Higher (full body wrap) | Lower (more distance from heating elements) |
Choose the blanket if
- You want maximum heat intensity (160–175°F vs 140°F for tents)
- You have limited storage space (blankets fold to yoga mat size)
- You don't mind (or enjoy) the cocooned feeling of being zipped in
- You want the premium crystal-lined experience (HigherDose is blanket-only)
- You travel with your sauna (blankets pack into a suitcase)
The HigherDose Infrared Sauna Blanket ($899) is the premium pick — crystal-lined, low-EMF, heats to 175°F. For budget buyers, the same factory makes decent unbranded blankets for $200–$400.
Choose the tent if
- You want to do long sessions (30–45 min) without discomfort
- You're claustrophobic or new to sauna use
- You want to read, watch TV, or use your phone during sessions
- You want lower EMF exposure (more distance from heating elements)
- You want to share the sauna with a partner (some tents fit two chairs)
The SereneLife Portable Infrared Sauna ($269) is the category leader — includes a folding chair, heated foot pad, and remote. Heats to 140°F in about 5 minutes.
The third option: sauna dome
Sauna domes split the difference — you lie down (like a blanket) but your head stays outside (like a tent). They offer 360° heat (most even of any option) and the most relaxing position. The trade-off is cost ($400–$700) and storage (domes don't fold up). The ZONEMEL Professional Infrared Sauna Dome ($549) is the best value.
What about EMF?
All infrared sauna devices emit some electromagnetic fields (EMF) from their heating elements. Quality brands (HigherDose, Sunlighten, Clearlight) publish EMF readings under 2 milligauss at the body surface — well below the 10 mG threshold most health agencies consider safe. Cheap unbranded blankets may emit 10+ mG.
If you're concerned about EMF, choose a sauna tent — the head-out design means more distance between your body and the heating elements. If you choose a blanket, stick with a brand that publishes EMF readings.
Whichever sauna you choose, pair it with your cold plunge for full contrast therapy. See our contrast therapy setup guide for the full protocol.
