heat therapy

This section is for those of you who want to dive a little deeper and understand the mechanisms of action. “Let’s get scientific”, will explain, in simple terms, the body’s response to heat exposure with references that support the claims made of them.

Before explaining the physiology associated with heat exposure, it is important to understand that Mind over Matter Practice is primarily focused on training you to become more resilient to stress. The reason this is mentioned here first is because we do not claim to cure disease. Rather, we offer to move your mind beyond its current definition of discomfort. Through your willingness to expose yourself to the unknown, not only will you develop your self-assurance, but also the ability to control your brain’s biological regulation of the stress response internally (Meine et al. 2021).

Welcome to our stress adaptation method, where we harness the power of hormesis and classical conditioning to unlock your body's incredible potential for functionality and tolerance. Get ready to embark on a transformative journey!

Hormesis is all about pushing your body to embrace stress at sub-threshold levels, triggering remarkable biological and physiological adaptations that elevate your overall well-being (Calabrese & Mattson, 2017). But we don't stop there. We combine this powerful concept with classical conditioning, creating a unique experience that blends varying temperatures with pleasurable sensations to unlock your body's true potential (Kim & Anderson, 2023).

As you step into our full-spectrum hybrid stream sauna, you'll be greeted by an immersive combination of heat and or infrared radiation, setting the stage for a remarkable transformation. Your skin and internal temperature will rise, activating sensory nerves that signal your brain to initiate an incredible nerve response.

Prepare to witness the magic as blood vessels just beneath your skin widen, redirecting circulation away from your internal organs and towards the surface for a refreshing cooling effect (Crandall et al., 2008). This incredible response is driven by heat stress-induced activation of enzymes, unleashing a surge of nitric oxide (NO) that orchestrates the mesmerizing dance of vasodilation (Kellogg Jr, Zhao & Wu, 2009).

But that's not all. Your body's natural intelligence kicks into high gear as specific glands in your skin start to release sweat, an ingenious mechanism designed to keep you cool through evaporation (Baker, 2019). And here's the icing on the cake: sweating not only cools you down but also helps eliminate those unwanted heavy metal toxins, including arsenic, mercury, lead, and cadmium (Sears, Kerr & Bray, 2012).

Your heart, the incredible powerhouse of your body, rises to the occasion. With blood redistribution, your heart's contraction force increases to compensate for the shifting dynamics within your circulatory system. Pressure-sensing nerves within your blood vessels sense the changes and nudge your nervous system to adjust your heart rate accordingly (Crandall & Wilson, 2015).

This orchestration of physiological marvels has far-reaching benefits. Research suggests that it can lead to improvements in arrhythmias, heart function, blood vessel function, and exercise tolerance, making it a game-changer for individuals with hypertension (Radtke et al., 2016). And guess what? It's not just about mimicking exercise; the thermoregulatory response takes center stage in delivering these physiological wonders (Hussain et al., 2022).

But the magic doesn't stop there. As your heart takes on the challenge, your respiratory rate increases, and your energy demand skyrockets, supercharging your metabolism like never before (Wingo, Ganio & Cureton, 2012). Brace yourself for an incredible journey towards weight loss, intensified with each session. And here's a secret: the larger your body mass, the greater the impact (Podstawski et al., 2019).

Now, let's talk about the incredible nitric oxide (NO). It's not just a vasodilator; it's a superhero that protects and enhances your cardiovascular system. It regulates your heart's rhythm, contractility, structure, and shields it from oxidative stress, a true champion for heart health (Zhang et al., 2014). And considering that inflammation, oxidative stress, elevated blood pressure, and cardiovascular function play a role in neurocognitive diseases, sauna therapy becomes a powerful ally in reducing these risk factors (Zeki Al Hazzouri & Yaffe, 2014). In fact, studies have shown an intriguing inverse association between sauna therapy and Alzheimer's disease and dementia (Laukkanen et al. 2017).
