Infrared Sauna Austin: What New Research Says About Sauna and Immune Cells
Infrared Sauna Austin: What New Research Says About Sauna and Immune Cells
Quick answer: A 2026 Finnish study found that a single 30 minute sauna session briefly increased every type of white blood cell in the bloodstream, which makes regular sauna time a reasonable, cozy habit to pair with your flu shot this fall, though it is not a way to prevent illness.
Fall is coming, the germs first
Austin still feels like August. The cold front is not here yet, but respiratory season is. Flu vaccines for the 2026 season are already in Austin pharmacies, and local doctors say flu sometimes shows up as early as late September or October.
So this is a good week to think about the habits that carry you through the next six months.
What the new sauna study found
Researchers at the University of Eastern Finland put 51 adults, average age 50, through a 30 minute Finnish sauna session with a short cold shower halfway through. They drew blood before and after.
Every type of circulating white blood cell went up, including neutrophils and lymphocytes, two of the body's main infection fighters. Those levels settled back to normal within about 30 minutes afterward. The researchers think heat moves immune cells out of storage and into circulation, similar to what happens during exercise.
What it does not mean
The team was clear about the limits. They measured one session, in a traditional Finnish sauna, not an infrared one. The study cannot say whether regular sauna use changes immune function over time or keeps anyone from getting sick. We read it as an interesting piece of the puzzle, not a promise.
A simple fall immune season routine
Get your flu shot. October is the sweet spot, and nothing in a sauna replaces it.
Protect your sleep. A warm session in the evening can help you wind down.
Keep moving, since exercise triggers a similar immune cell shift.
Book regular heat. Two to three sessions a week in our Infrared Sauna Suite or the full spectrum Cabana builds a rhythm you can keep.
Add full body red light therapy on busy weeks for skin and muscle recovery.
Hydrate well before and after every session, especially while Austin is still in the 90s. Skip the sauna if you already feel sick or feverish, and check with your doctor first if you are pregnant, take medication, or have a heart or blood pressure condition.

Frequently asked questions
Does a sauna boost your immune system?
A 2026 study found one 30 minute session temporarily raised white blood cell counts in the blood, and levels returned to normal about 30 minutes later. Researchers do not yet know whether regular sessions change immune function long term.
Can a sauna prevent the flu?
No. No sauna study shows it prevents flu. Treat sauna time as one supportive habit alongside vaccination, sleep, and handwashing.
Should I use a sauna when I am sick?
It is best to skip the sauna if you have a fever or feel unwell. Rest, fluids, and your doctor's advice come first, and staying home also protects other guests.
How often should I use an infrared sauna in the fall?
Two to three sessions a week is a common rhythm. The intro pack, 3 sessions for $99, is an easy way to test it.
Is infrared sauna the same as a Finnish sauna?
No. A Finnish sauna heats the air around you. An infrared sauna warms your body more directly at a lower air temperature, which many people find easier to tolerate. Most published immune research used traditional saunas.
