FREQUENTLY ASKED QUESTIONS

general questions

Yes! As a membership holder, you can use any SweatHouz location! Please note a surcharge may apply at some studio locations.
Your introductory session includes two modalities. First, most clients start their session off with an infrared sauna session and then try out either the cold plunge or the recovery room. Your infrared sauna session is 60 minutes in your private suite equipped with an infrared sauna and vitamin-C-infused shower. After your sauna session, you can choose to cold plunge or visit the recovery room and use the hydromassage bed and Hyperice recovery tools.
We encourage our guests to dress up or down to their comfort level. We do recommend loose fitting clothing to wear after your session.
We do have water for purchase in the studio.
Each of our suites are private so you can change comfortably in the privacy of your own suite.
Yes! Each private suite comes with a vitamin-C infused shower.
You can ask a staff member to change the color of your chromotherapy light panel prior to the start of your session or you can tap the black tab on the side of the light panel to change the color.
“The American College of Obstetricians and Gynecologists (ACOG) recommends against using saunas and hot tubs throughout pregnancy. Raising the core body temperature in pregnant women is linked to poorer pregnancy outcomes, like neural tube defects.

ACOG recommends that pregnant women avoid letting their core body temperature rise above 102.2º F, which can occur in just 10-20 minutes of hot water or hot air immersion. SweatHouz is aligned with ACOG, and staff should direct members to seek guidance from their physicians. Our client intake waiver does mention pregnancy when discussing the risks of our Services.”
Yes! We provide towels as well as shampoo, conditioner, and body wash in your private suite.
No worries, please note that your appointment has a specified start and end time to allow our staff to properly sanitize the room before the next appointment so you will lose time on your session if you arrive late.

Yes! You may bring a guest with you to accompany you in your sauna suite for an additional fee. This plus one price is only associated with infrared sauna sessions and varies based on studio. Contact your local SweatHouz to learn more and book a plus one!

“A ) Your core body temperature increases during a sauna session, after which your body works hard to thermoregulate and ‘cool off.’

B) Taking a very hot shower essentially prolongs your exposure to heat stress, slowing down or impeding your body’s ability to thermoregulate. This may not be safe or advised for everyone. Thus, we recommend trying out a lukewarm shower, where the water temperature doesn’t feel cold or hot to the touch (98 – 105°F), to allow your body to naturally cool down after your sweat.”

infrared sauna

Our infrared saunas are set to 140 degrees Fahrenheit. You can lower or raise your sauna’s temperature once you start your session on the control panel inside the sauna. You can notify the staff to note your preferred temperature on your profile so your sauna will always be set to the correct temperature.
Each sauna session is 60 minutes. We recommend using the infrared sauna for up to 45 minutes and then using the rest of the time in your private suite to shower and get dressed. We suggest starting off with a lower temprature (140 degrees F) and/or spending less time in the sauna (25-30 minutes) for your first couple of appointments.
Frequent infrared sauna use provides a multitude of benefits. Our favorite benefits are increased collagen and elastin production, muscle recovery, and detoxification.
Members are encouraged to use the infrared sauna at least 2x/week to notice longer-term physiological changes. But, listen to your body. Use caution after a vigorous intensity workout, especially. Monitor for signs of lightheadedness, dizziness, confusion, shortness of breath, sweating less than normal, etc. Monitor hydration status and consider shorter exposure time and/or lower temperature.
From a physiology perspective, an infrared sauna session increases your core body temperature. Your core body temperature is already elevated if you have a fever. Our goal is to avoid hyperthermia, as internal temperatures of 104*+ in adults can be life threatening. Placing adults with fever into the sauna may pose serious risk. A narrative review published in 2021 by Dr. Rhonda Patrick and her team concludes that “individuals with acute illness accompanied by fever or those with inflammatory skin conditions should avoid sauna use.”
There is some evidence to suggest that exposure to deliberate heat stress, like the sauna or a hot tub, may negatively impact sperm health in the short-term. However, there are many factors that should be considered when discussing sperm health and fertility overall. Thus, we recommend that you touch base with your healthcare provider for any individualized health-reated questions.
From Clearlight®: “The EMF levels in your Clearlight PremierTM and Clearlight SanctuaryTM saunas will be mostly below 1mg when tested directly on the heater itself. Where you are sitting in the sauna, the EMF levels are virtually 0mg. The ELF levels in your Clearlight Infrared SaunaTM are 3 – 5 times below the threshold of concern.”
“Pacemakers send electrical pulses to help your heart beat at a normal rate and rhythm. They also help your heart chambers beat in sync so your heart can pump blood more efficiently to your body. The NIH recommends that people with pacemakers use caution around devices that emit radiation. Individuals with pacemakers and other electrical implants should speak with a healthcare provider before using our infrared saunas.”
Persons under the influence of alcohol are strongly advised not to use the sauna, cold plunge, or any of our SweatHouz modalities. Using the sauna while under the influence of alcohol likely increases the risk of cardiac or other adverse event.
“We encourage you to speak with your healthcare provider for any individualized questions. Clearlight, the manufacturer of our infrared saunas, has informed us that it is safe for most women with breast implants to utilize an infrared sauna.

The majority of breast implants in the US are made of either saline (12%) or silicone (88%). Silicone breast implants melt at a much higher temperature (300*F+) than they would reach in an infrared sauna.”
“A ) Depending upon the water temperature in the shower, cold showers can mimic the physiological response to cold plunging (i.e., vasoconstriction, analgesic/pain relief, reduced inflammation) and may provide a time efficient way to add deliberate cold exposure to a sauna session. B ) Contrast therapy, or immediately transitioning from the infrared sauna into a cold shower or plunge (< 59°F), has been investigated as an effective way to improve circulation and speed up recovery from acute injury, among other benefits.

C ) Importantly, contrast therapy has significant vascular implications – i.e., vasoconstriction of the blood vessels in the cold and vasodilation in the heat – and may not be recommended for individuals who have current heart conditions, are pregnant, or have uncontrolled blood pressure.

D ) Safety is relative to the person. For this reason, we recommend a conservative approach of waiting a few minutes between hot and cold exposures.”

cold plunge

A cold plunge is cold water immersion. Cold plunge, most commonly recognized in sports recovery and physical therapy, has grown increasingly popular to the public for its many health benefits. Three to five minutes in our Renu Cold Plunge can help you recover faster, feel more alert and invigorated, think clearer, reduce inflammation and pain, and burn calories.
Cold plunging can help improve circulation and mood, boost your immunity, increase thermogenesis, boost your metabolism, reduce inflammation, reduce chronic pain, improve sleep, and boost energy!
The cold plunge is set to 50 degrees Fahrenheit.
Your cold plunge room is reserved for 15 minutes. We recommend cold plunging for up 3 to 5 minutes. If you are new to the cold plunge, aim for 30 seconds of exposure using a box breathing technique (inhale for 4 seconds, hold it for 4 seconds, exhale for 4 seconds, hold it for 4 seconds). You can build up toward the 3 minute mark over time and with practice.
We recommend trying the box breathing technique while in the cold plunge. Box breathing involves inhaling for 4 counts, holding for 4 counts, exhaling for 4 counts, and holding for 4 counts. Focusing on a breathing technique can help you stay present and committed to the deliberate cold exposure.
Cryotherapy uses liquid nitrogen in a specialized chamber. Like cold water immersion, cryotherapy also lowers core body temperature, causes vasoconstriction and redistribmution of blood flow, can provide temporary pain relief, and more.Cold plunge is more customizable (partial immersion), accessible, safer, and some research suggests it may be more effective at reducing feelings of soreness and recovery post-workout.

recovery room

Your recovery room is reserved for 25 minutes. Most guests like using the hydromassage bed for 15 minutes and then use the remaining time to utilize the Hyperice recovery tools.
The recovery room contains a hydromassage bed equipped with a Celluma LED light therapy device that helps treat acne, wrinkles and pain. The room also has various Hyperice tools to help further your recovery.
Most research studies have shown positive results after using Redlight Therapy several times per week for 4 or more weeks. Consider accessorizing your sweat with Redlight Therapy at least once per week, depending on your membership package.
We recommend having clean, dry skin while using the Redlight Therapy. Following your Services, utilize our private en suite showers and Beauty Bar as needed.
Chromotherapy, also called Color Therapy, is a holistic health tool that may alter your mood. Chromotherapy is available as part of our infrared sauna experience to help members create a relaxing environment customized to their preferences. Redlight therapy, in contrast, is an FDA-approved class II medical device that uses LED light to promote skin health and cell regeneration.

vitamin-c shower

A ) Skin is our largest organ and plays important roles in protecting us from the external environment. For example, skin is our first line of defense against UV-induced damage, and even dehydration.

B ) Healthy, normal skin contains large amounts of the antioxidant Vitamin C. Studies suggest that topical Vitamin C, when used consistently, may improve skin tone and texture, help the skin stay hydrated, and contribute to a brighter complexion. You can read more about Vitamin C and the skin in this article.
