Strengthen Immunity this Winter Season with Infrared Sauna

Immunity, Holistic Wellness

Winter in Australia often brings clear skies and crisp mornings, perfect for outdoor activities and despite the cooler weather, many Aussies still embrace winter with enthusiasm, enjoying outdoor activities such as skiing, running and hiking. However, winter is also an extremely important time for us to hibernate and nurture our well-being. With the winter season soon upon us, the battle against the common cold and flu is at an all-time high.

But what if there was a way to fortify our defences and bolster our immune system, so that we can enjoy the simple pleasures of the cooler season without the hindrance of a cold or the flu? While there is no effective method of prevention and treatment for the cold and flu entirely, infrared saunas have the power to reduce our susceptibility to the winter flu blues.

Understanding the Science

The body's natural defence mechanism against infections is fever, which creates a hostile environment for pathogens. Infrared saunas, such as those from Sunlighten, elevate core body temperature, priming the immune system for combating seasonal illnesses.

Infrared saunas penetrate deep into tissues, raising core body temperature to approximately 102°F (39°C), thus preparing the immune system for the challenges of cold and flu season.

Heat sensitivity plays a crucial role in immune function, as fever-range temperatures prompt the immune system to better remember encountered pathogens, enhancing its ability to combat future exposures.

The concept of hormesis further elucidates the immune-boosting potential of infrared saunas, as controlled heat stress promotes adaptability and resilience.

Navigating Stress and Aging

Stress, a common companion in modern life, weakens immune resilience by elevating cortisol levels. Infrared saunas counteract this effect by reducing post-exercise cortisol and inducing mild oxidative stress.

Aging poses challenges to immune health too, with declining stem cell activity impairing the body's ability to replenish immune cells. Photobiomodulation, particularly from near-infrared wavelengths, shows promise in stimulating mitochondrial function and mitigating age-related immune decline.

Embracing Circadian Rhythms and Sleep

Deep sleep is pivotal in nurturing the antiviral arm of the immune system. However, disruptions to circadian rhythms, exacerbated by diminished light exposure in winter, can compromise this defence. Infrared saunas offer a potential solution by mimicking the body's natural temperature fluctuations, thus restoring sleep patterns, and reinforcing immunity.

The Sunlighten Advantage

Sunlighten's mPulse Smart infrared sauna is the first and only sauna to offer 3 in 1 full-spectrum infrared therapy, integrated with red-light to further enhance the wellness benefits for you to enjoy.  Programmed, personal and precise, the mPulse sauna is meticulously calibrated to deliver each wavelength at its peak, providing the most comprehensive approach to immune enhancement.

The near-infrared spectrum stimulates immune cell growth by activating the mitochondria, bolstering white blood cell production, and augmenting germ-fighting antibodies. These benefits are amplified by combining red-light with the near infrared to further increase the production of white blood cells to strengthen your body’s protection against disease.  While mid-infrared wavelengths, absorbed by the body, harness the immune-stimulating effects of heat, promoting overall well-being and enhancing sleep quality.

Charting a Course to Resilience

In the quest for immune resilience this winter, understanding the interplay between environmental stressors, bodily responses, and therapeutic interventions is paramount.

By harnessing the restorative power of infrared saunas and embracing hibernation and healing, individuals can forge a path towards strengthened immunity, arming themselves against the harsh winter ahead.
