Like you, we have been actively monitoring the latest news about the 2019 Novel Coronavirus (2019-nCoV) and remain committed to keeping you informed on how to protect yourself as the situation unfolds. You can absolutely strengthen your immune system to reduce the chance of your getting sick. After all, viruses can only make you sick if your immune system allows it. Beyond Cryotherapy offers several services to strengthen your immune system to keep you healthy to fight off threats from viruses, bacteria and germs! This blogpost highlights the immune boosting benefits of our Sunlighten Infrared Sauna.
The term “hormesis” refers to a small amount of stress that trains the body to get stronger. Exercise is a type of hormesis. Many health benefits from our Whole-Body Cryotherapy and the Infrared Saunas are due to hormesis.
Using an infrared sauna will generate heat stress and oxidative stress at specific low levels to help your body better deal with these stressors. Such heat exposures trigger the production of heat-shock proteins, which help other protein molecules fold correctly. In addition, heat-shock proteins also help the immune system fight off viruses (1).
Too much oxidative stress can damage tissues and immune cells, which reduces your ability to fight infections. At Beyond Cryotherapy, our Whole-Body Cryotherapy and Sunlighten Infrared Sauna generates small amounts of oxidative stress that increases your cell’s antioxidant capacity, reducing your risk of getting sick (2).
How Heat Improves Immune Function
When you have an infection or a virus, your immune system induces fever to stimulate immune function and make the body less habitable for the pathogens (3). Generally, fevers under 104°F (40°C) help the body fight off pathogens without the risk of febrile seizures.
According to the American College of Critical Care Medicine, fever is defined as a core temperature of 100.9°F (38.3°C) or higher, i.e. just above the upper limit of an average human temperature, irrespective of the cause (4). Beyond Cryotherapy’s Sunlighten Sauna can penetrate deep into tissues and raise core body temperature to approximately 102°F (39°C). Although the sauna heats you up differently than a fever does, the increased body temperature can provide many benefits of fever, such as improving immune functions and preparing your body for bacterial and viral threats making your antiviral and antibacterial immune responses more efficient.
Fever Induction Fights Infections
Many aspects of our immune fighting powers are heat-sensitive and designed to be readily mobilized in response to a fever. As a result, fever-range temperatures can help your immune system better remember germs that you are exposed to, so that the next time you encounter them, your body can fight them off better (5).
In addition to heating the body, the near-infrared light in Beyond Cryotherapy’s Infrared Sauna can also stimulate white blood cells and increase antibodies to protect the body against bacteria, viral and other germs by increasing cellular energy production (6).
Promoting Anti-aging for the Immune System
The immune system, which is continually replenished by immune stem cells in the bone marrow and thymus, is one of the most sensitive systems to aging. This is why the elderly (>65 years old) are more likely to get sick and develop complications from cold and flu.
As people age, their immune stem cells have a declining ability to regenerate more white blood cells. Interestingly, photobiomodulation, especially from the near-infrared spectrum, can stimulate the mitochondria of these stem cells and help mitigate age-related immune decline (7).
Stress significantly increases the incidences of colds by reducing the antiviral immune system, partly because cortisol suppresses the immune responses (9, 10, 11). Exposure to the far-infrared wavelengths of the Beyond Cryotherapy Sunlighten Infrared Sauna significantly reduces post-exercise cortisol, which may mitigate the immune-suppression effects of stress (12, 13).
Normalizing the Circadian Rhythm and Improving Sleep
Not all sleep is created equal. Deep sleep helps build your antiviral immune system, so you want to increase deep sleep in the winter (14).
During colder months, when the days are shorter and the sunlight is dimmer, your sleep could get thrown off. You may hardly notice it because you are still going to work and sleep on the same schedule, but you may experience changes in mood, fatigue, and more frequent colds partly because you are not sleeping as deeply.
According to board-certified sleep psychologist Dr. Micheal Breus, the steep drop in body temperature in the evening helps cue your body that it is time to sleep. Using the Beyond Cryotherapy Sunlighten Infrared Sauna in the afternoon can help you relax, allowing your body temperature to drop naturally at night to improve your sleep quality.
Using the Sauna Reduces Incidences of Common Cold
In an Austrian study, 25 healthy subjects who regularly used saunas had significantly fewer episodes of common colds than those who did not (15). This benefit becomes more significant, especially after 14 weeks of consecutive sauna use. Therefore, in order to fully experience the immune-strengthening benefits of sauna use, you want to use it regularly. At Beyond Cryotherapy, we recommend using the Sunlighten Infrared Sauna at least twice a week throughout the year.
Beyond Cryotherapy Sunlighten Infrared Sauna mPulse 3-in-1 Infrared Sauna
To maximize the synergistic immune-boosting benefits of the infrared sauna, use a full-spectrum infrared therapy. The near-infrared spectrum can stimulate immune cell growth and activity by stimulating your mitochondria. The mid-infrared spectrum penetrates deep into your tissues, ensuring that you benefit from the immune-stimulating effects of heat throughout your body and improving your sleep. Lastly, the far-infrared spectrum possesses great healing and anti-stress benefits.
At Beyond Cryotherapy, we offer the Sunlighten mPulse Sauna that provides true full-spectrum infrared therapy with separate heating elements to deliver each wavelength at their peak. Other sauna companies claim to provide “full spectrum” but only have one or two heating elements. They may produce light throughout the entire visible spectrum, but they can’t reach the peak infrared wavelengths to produce the health benefits.
The Beyond Cryotherapy Sunlighten Infrared Sauna is the only infrared sauna on the market designed to keep you healthy, boost your immune system to protect you from viruses, bacteria and germs while allowing you to meet your exact wellness goals.
