Infrared Sauna for Stress Relief: What the Research Says

Some stress lives in your head. Some of it lives in your shoulders, your jaw, and the tight knot between your shoulder blades. Infrared sauna for stress relief works on both, which is a big part of why it's one of our most-booked therapies at Rejuvenate Mind Body in Glendale, Arizona.
Let's look at what the research says, and what a session actually feels like.
What sauna does for your stress response
Cleveland Clinic notes that sauna use* may help reduce stress, support heart health, ease pain, and soothe sore muscles. A physician there also shared that there's evidence sauna use helps people in high-stress work or personal situations, and that it appears to improve anxiety.
A review in Mayo Clinic Proceedings adds historical context: sauna bathing* has long been used for pleasure and relaxation, which evidently help ease the stresses of everyday life. In other words, people have been sweating their way to calm for a very long time.
Why heat calms the body
While researchers are still working out the mechanisms, there are a few leading ideas:
Muscle relaxation: Heat helps tense muscles soften, and a looser body often signals a calmer mind.
A nervous system handoff: Heat is a gentle, controlled stressor. Your heart rate rises, your body warms up, and then, as you cool down, many people feel their system shift toward "rest and digest" mode. That calm-down window is a big part of why people feel so settled afterward.
Feel-good chemistry: Warmth and a light rise in heart rate may prompt the release of endorphins, the body's natural mood lifters. It's one reason that post-sauna glow feels a lot like the calm after a good walk or workout.
A forced pause: There's no phone, no inbox, and nowhere to be. That quiet may matter as much as the heat.
The cool-down: Many people feel deeply relaxed afterward, which is one reason evening sessions are popular for sleep.
Stress and sleep go hand in hand
Stress and poor sleep tend to feed each other: a restless night makes the next day's stress feel heavier, and a stressful day makes it harder to wind down at night. Many members tell us an evening session helps break that loop. Warming up and then cooling down may help your body ease into rest, so you get to bed more relaxed than you started the day.
Why consistency matters
One session can leave you feeling lighter, but stress relief tends to build with practice. Making sauna a regular rhythm gives your body a dependable place to downshift, and gives you a weekly appointment with calm. Think of it as a small, steady habit rather than a one-time fix. Most members find that once it's on the calendar, it becomes the part of the week they protect.
What makes infrared different
Traditional saunas heat the air around you. Infrared saunas use light wavelengths that warm the body more directly. Ours runs at about 165°F, and most members feel a deep, comfortable heat without the intensity of a traditional sauna.

What a session at Rejuvenate looks like
Duration: Most members spend 10 to 20 minutes. Step out if you feel dizzy or overly uncomfortable.
Hydration: Drink 16 to 24 oz of water beforehand and rehydrate after. LMNT electrolytes are available at the studio.
Clothing: Light shorts or swimwear. Less clothing means more infrared exposure.
Breathing: Breathe slowly through your nose and let your exhale run longer than your inhale. It's a simple way to lean into the calm.
After: Let your body cool naturally, or follow with a cold plunge for contrast therapy.
Arizona has plenty of heat already, so it's fair to wonder why you'd seek out more. The difference is choosing it: a controlled, hydrated, phone-free kind of warm.
The bottom line
Infrared sauna isn't a cure for stress, but it's a genuinely restorative way to slow down. Research on sauna use* suggests it may help lower stress and ease anxiety, and the calm most people feel afterward speaks for itself.
