(NC) Wellness may seem like a buzzword, but it has been embraced by cultures all around the world for generations. Public bathing, for example, dates back centuries, with large bathing facilities used in ancient Rome as early as 25 BC.
Today, heat and cold are being used as tools to support rest, balance and recovery. With the popularity of hot Nordic saunas with cold-water plunges, many North Americans are rediscovering why thermal practices have survived the test of time.
Technically known as contrast therapy, the practice involves alternating between hot and cold temperatures. While saunas have had a more consistent presence at spas, gyms and wellness centres over the years, cold therapy has only recently gotten more popular. Once associated mainly with post-performance recovery for elite athletes, it’s now part of broader conversations about fitness and mental well-being.
That growing interest is also shaping the design of wellness spaces, with companies such as Therme Group among those incorporating sauna, cold-water and bathing rituals into modern facilities.
But beyond the trend, what does moving between heat and cold actually do?
How it helps:
Contrast therapy is often described as a workout for the vascular system. The exposure to heat widens blood vessels, which can increase blood flow and support circulation while also helping muscles relax. Heat may also help calm the nervous system and support the release of endorphins.
Cold has a different effect on the body. Short, controlled exposure, which beginners can start with for as little as one to two minutes, can help activate the nervous system and increase alertness. When practiced safely, cold exposure may also help support recovery and reduce temporary muscle soreness.
The mental health impact
Many people spend extended periods in a state of stress, often described as “fight or flight”. Over time, this can affect sleep, energy and overall well-being. Thermal experiences may offer a natural reset by creating a structured pause from daily stress, with many people reporting feeling calmer afterward.
The idea of using water and temperature as part of a wellness routine is not new. In ancient Rome, these rituals were part of daily life and connected to both physical and social well-being.
Consistency over intensity
Like exercise and healthy eating, consistency matters more than intensity. Regular thermal experiences may offer more meaningful benefits. For many people, a few 20 to 30-minute sessions each week can be a practical place to start, depending on personal comfort and health status.
