In the ever-evolving realm of wellness, trends come and go like tides in the ocean, and amidst all the chatter, cold water therapy is making a notable splash. The notion of willingly subjecting oneself to the icy clutches of cold water might raise eyebrows, yet beneath the surface, there appears to be more than meets the eye. Cold water therapy, often dubbed hydrotherapy or cryotherapy, involves brief immersions in chilly waters at temperatures that are physically uncomfortable and instigate a lot of physiological mechanisms in the body. Intrigued by its potential, we dug deeper to put together a list of cold therapy techniques suitable for beginners & to understand whether this is just a transient trend or if there’s genuine merit to its claims.
The Origin of Cold Therapy
While the practice of using the cold to treat various injuries and inflammation dates back to the ancient Egyptians, Cryotherapy as we know it goes back to the 19th century when localised cooling was employed to manage pain and address advanced cancers.
The advancement of vacuum flasks for storing liquefied gases played an important role in the evolution of cryotherapy. This eventually led to the utilisation of liquid carbon dioxide (-78.5℃) in the early 1900s by Lortat-Jacobs and Solente in Paris. They applied it to treat skin and gynaecological lesions.
Following World War II, liquid nitrogen (-196℃) became accessible. In 1950, Dr Ray Allington employed cotton swabs dipped in liquid nitrogen to treat various non-neoplastic skin diseases. However, the first clinical use of cryotherapy on skin diseases was reported by a physician, Campbell White, in the United States in 1899. The widely used nitrogen spray device that we use today was pioneered by Dr Douglas Torre in 1965.
Benefits of Embracing the Chill
Recent studies propose that temporary exposure to the cold can trigger a surge in heart rate and adrenaline, providing a natural boost in energy. A brisk cold plunge can invigorate your senses and enhance your focus, acting as a worthy replacement (or addition) to your morning cuppa.
Beyond the immediate effects, the benefits extend to better circulation too. Cold water exposure can amplify blood flow, purging toxins and facilitating the efficient conveyance of oxygen and nutrients throughout the body. The “fight or flight” response ignited by the cold also prompts a temporary elevation in metabolism.
But that’s not all—cold water may not solely impact the body but also influence mood. A study conducted in 2008 revealed that cold showers might serve as mood enhancers, potentially due to the endorphin rush experienced during the chilly encounter. Here’s the intriguing part though: Cold water therapy also has the potential to elevate motivation by unleashing the Neuromodulator Dopamine. This surge in dopamine heightens focus and attention, and even uplifts spirits. Short interludes of cold exposure could culminate in a sustained elevation of dopamine levels, ensuring motivation, enhanced focus, and an elevated mood.
Taking the Plunge
If you’re eager to explore cold water therapy, start small by adjusting your shower’s temperature. Rest assured, subjecting yourself to icy water isn’t the immediate goal. Start with your regular warm shower and progressively lower the temperature over a span of one to two weeks, until you find yourself comfortable with a cold shower. The key is to make it uncomfortably cold yet safe enough to endure for a few minutes.
Research implies that dedicating just 11 minutes weekly to cold exposure is sufficient to harness its rewards. Of course, if you’re inclined, you can do more, but this serves as the threshold for reaping the frigid benefits. Mind your body and advance cautiously though as your safety takes precedence, particularly if you contend with health conditions like hypertension or cardiovascular ailments.
Once you’ve acclimatised to the chill, you can elevate the experience with a specialised plunge or a professional cryotherapy centre. Whether it’s an elaborate setup with temperature controls or a modest container brimming with ice and water, the choice is yours to make. As with any health endeavour though, adopt a mindful approach and heed your body’s cues. If you suffer from underlying health conditions, make sure you consult a healthcare professional before you immerse yourself.
