Keep reading to learn more about SWTHZ, a new contrast therapy studio in Edgewater, New Jersey.
So… What is Contrast Therapy?
Contrast therapy studios are the latest wellness craze, and for good reason. The idea is simple: alternate between hot and cold temperatures using saunas and cold plunges. Deliberate exposure to heat and cold is scientifically proven to boost your physical and mental well-being, according to the SWTHZ team.
This is the setup at SWTHZ. Each session starts in the sauna, with infrared heat technology that aids in muscle recovery and helps detox the body. Unlike traditional saunas that heat the air inside, SWTHZ saunas heat the body directly and at a lower temperature. The team says that this method helps improve complexion, muscle recovery, mood + heart health, metabolism, and pain relief.
Following the infrared sauna is the Vitamin C-infused shower, a cool-down that rejuvenates the skin. After that, it’s time for the grand finale: the cold plunge. Here, guests will submerge in a 48-55ºF bath — an experience that sounds intimidating but can have lasting effects, reducing inflammation, improving circulation, focus, immune responses, and even sleep patterns.
SWTHZ recommends that guests alternate between the sauna and cold plunge a few times during a session to maximize benefits. This unique recovery journey is scientifically proven to promote optimal mental and physical performance, according to the SWTHZ team.

State-of-the-Art Amenities
The state-of-the-art studio, coming to Edgewater soon, features 10 thoughtfully designed private suites for relaxation and recovery.
Each suite is packed with luxury amenities, including an in-suite entertainment system for those who want to unwind with music, their favorite podcast, or TV show. But if it’s peace + quiet you’re looking for, the space can also be an oasis to unplug, meditate, and enjoy the calm. When it’s time to head out, there’s a beauty bar stocked with Dyson hair tools to help guests freshen up.
The studio has exclusive memberships available that locals can lock in at the lowest rates and enjoy early access before the official opening. With a membership, you’ll have access to the private suites, infrared saunas, cold plunge, and vitamin-C shower. Memberships are month-to-month with no upfront charges. SWTHZ is currently awaiting an official opening date but has assured HG that the Edgewater location will be up and running soon.
Don’t forget, SWTHZ has exclusive founding membership deals available.
SWTHZ is located at 725 River Road in Edgewater.
