Embrace the effects of hot and cold with Tranquil Tides

Researchers from the University of Eastern Finland tracked 2,300 middle-aged men for an average of 20 years. They categorized the men into three groups according to how often they used a sauna each week. The more frequent the visits to the sauna, the more significant a drop was found in all-cause mortality. Cardiovascular improvements lead better circulation, oxygenation and in turn lower risks of heart disease, stroke, and Alzheimer's.
For centuries, diverse cultures around the world have harnessed the benefits of alternating heat and cold exposure. Only recently, however, has the science uncovered mechanisms behind these practices, such as heat shock and cold shock proteins, which are linked to increased longevity. These findings are validating the traditional wisdom of numerous societies—from the sweat lodges of American Indians to the steamy banyas of Russia to the mineral-rich onsens of Japan and of course the Swedish bastu and Finnish sauna are all now being viewed in a new light, as modern science confirms the health advantages these cultures have celebrated for generations.

Hot Sauna
Finnish Style Sauna!
Our Finnish style wooden sauna will reach over 185 degrees Fahrenheit triggering your heat shock proteins and longevity boosting benefits. To increase steam inside, there is nothing more lovely than adding water onto the rocks and hearing them sizzle. We will provide you with towels and electrolyte blends to ensure hydration is maintained.
Cold Plunge
Scandanavian Iskallt dopp!
Some prefer dunking into cold water prior to a relaxing sauna, but most traditional experiences start with a long sauna, and finish with a quicker cold plunge! We will leave that decision up to you. Our cold plunge water is generally in the 40 degree Fahrenheit range with ice floating on the top layer of the water. Cold shock proteins will be triggered, and your body will be flooded with endorphins after you use it leaving you feeling fantastic for hours.
