Short answer
A sauna blanket is a portable, dry, zip-up heater you use at home with your head outside. A steam room is a sealed room filled with humid steam, usually around 110–120°F, that you sit in and breathe. The blanket is cheaper and private; the steam room needs a gym or a built-in install. Neither one detoxes you or burns fat.
Both make you warm and sweaty, but they work in very different ways. Here is a plain comparison of heat, humidity, cost, setup and safety, using manufacturer specs rather than marketing claims.
Sauna blanket vs steam room at a glance
| Sauna blanket | Steam room | |
|---|---|---|
| Heat | Infrared heating elements around your body | Steam from a generator fills a sealed room |
| Humidity | Dry air; the moisture is your own sweat | Very humid air you breathe |
| Temperature (example) | HigherDOSE: settings up to 175°F (element setting) | MrSteam control: about 80–120°F, default 110°F |
| Session (example) | HigherDOSE: start with 30–40 minutes | MrSteam control: 20-minute default |
| Your head | Outside the blanket, in room air | Inside the steam |
| Setup | Standard outlet; HigherDOSE lists 350–420 W | Enclosed, insulated, sealed shower plus generator on 208 V or 240 V |
| Where | Home or travel | Gym, spa, or a built-in home steam shower |
How each one heats you
A sauna blanket wraps around you like a sleeping bag. HigherDOSE describes far-infrared heating elements, a one-hour timer and levels 1 to 9, and tells users to wear long sleeves, pants and socks or an insert so skin does not touch the heated surface. Your head stays out, which some people find easier to tolerate.
A steam room is a sealed space where a generator boils water and pumps steam in until the room reaches its set temperature. MrSteam’s iTempo control manual lists a range of 80°F to 120°F with 110°F as the default and a 20-minute default session. You breathe the warm, wet air, which is the main difference from a blanket. For how steam compares with other heat, see sauna and steam room temperatures.
Cost and setup
A sauna blanket plugs into a normal outlet and folds away. HigherDOSE listed its blanket at $699 on 17.10.2026; many others cost less. See how much sauna blankets cost for the range, and plan for an insert or cotton clothes to keep it clean.
A home steam room is a building project. MrSteam says the shower must be enclosed, insulated and sealed, with no heating, venting or air-conditioning parts inside, vapor-sealed lights, a water line, steam line and drain line, and household power at 208 V or 240 V. It recommends a licensed contractor. Most people use a steam room at a gym or spa instead.

Breathing and a blocked nose
Warm, humid air can feel soothing when your nose is stuffy. That is comfort only; it does not treat a cold. A sauna blanket does not change the air you breathe, so it offers no such effect. If you have a fever or feel unwell, skip both. More in using a sauna when you are sick.
Sore muscles after exercise
Heat often feels good on tired muscles. A study often quoted for “moist heat” (Petrofsky et al., 2013) tested chemical heat wraps on the thighs of 100 young adults after squats, not steam rooms or sauna blankets. Moist wraps applied right after exercise gave the most pain relief, and dry wraps a smaller effect. So it says little about choosing between the two. Use whichever you find more comfortable, and see sauna vs steam room after a workout.
Weight loss and calories
You will weigh less after either session, but that is sweat. It comes back when you drink, and neither one burns off belly fat. Details in steam room vs sauna for weight loss and does the sauna burn calories.
Safety for both
- Drink water before and after, and avoid alcohol before heat. Harvard Health also advises cooling down gradually afterwards.
- Get out if you feel dizzy, sick, get a headache or cramps. These can be signs of heat exhaustion.
- Pregnant people: ACOG advises against saunas and hot tubs early in pregnancy, because a rise in core temperature can be harmful.
- If you have a heart condition, low blood pressure or take regular medication, ask a doctor first.
- Never fall asleep in a sauna blanket. See are sauna blankets safe.
Which should you choose?
Pick a sauna blanket if you want a cheap, private session at home and do not mind lying down. Pick a steam room if you like humid heat, want to sit up and already have access through a gym or spa. If you have both, you can use them on different days. For other comparisons see sauna blanket vs infrared sauna and infrared sauna vs steam room.
Frequently asked questions
Is a sauna blanket better than a steam room?
Neither is better for everyone. A sauna blanket is cheaper, private and fits in a cupboard. A steam room gives humid heat you breathe and room to sit up, but you need a gym, spa or a sealed, built-in steam shower.
Which is hotter, a sauna blanket or a steam room?
The numbers are hard to compare. HigherDOSE lists blanket settings up to 175°F, which is the heating element setting. MrSteam residential controls run from about 80°F to 120°F of humid air, with 110°F as the default. Humid air feels hotter at the same temperature.
How long should a session be?
Follow the product or the facility. HigherDOSE suggests starting with 30 to 40 minutes in its blanket. MrSteam’s control has a 20-minute default session. Get out sooner if you feel dizzy, sick or too hot.
Does a steam room help a blocked nose?
Many people find warm, humid air soothing when their nose is stuffy. That is comfort, not a cure, and a sauna blanket does not humidify the air you breathe. Skip both if you have a fever.
Do sauna blankets or steam rooms help you lose weight?
Not fat. The weight you lose in either one is mostly sweat, and it comes back when you drink. Use them to relax, not as a weight-loss tool.
Can I use a sauna blanket and a steam room on the same day?
Healthy adults can, if they cool down between sessions, drink water and stop at the first sign of feeling unwell. Do not stack long sessions back to back, and avoid alcohol.
