Since the very start of the pandemic I have been recommending hydrothermal therapies such as hot baths, saunas, hot springs etc as simple, cheap, widely available and effective ways to prevent and treat respiratory viral infections. This recommendation was based on my knowledge of basic physiology and immunology, my personal experience with these therapies, and my decades of researching and practicing natural medical treatments, which includes publishing a review of clinical benefits of sauna bathing and conducting studies of sauna bathing and hot springs bathing. I was therefore surprised when many of my posts and recommendations were getting censored and I was somewhat dismayed when I began to be personally attacked by social media trolls who accused me of being ‘irresponsible’ for promoting treatments that no ‘respectable doctor’ would promote, because ‘hydrothermal treatments are unscientific’.
The justification people used for attacking me were not based on any scientific studies. Instead they were based on statements from the WHO which (still) says “your normal body temperature remains around 36.5 C to 37 C regardless of the temperature of your bath or shower“, along with statements from multiple mainstream media outlets such as the BBC, which quote ‘experts’ such as Prof Bloomfield. who says “Once the virus is in your body, there’s no way of killing it – your body just has to fight it off. . . And having a hot bath or drinking hot liquids won’t change your actual body temperature, which remains stable unless you are already ill.”
There are also literally dozens of ‘fact-checking’ sites such as AFP Fact-check, which quote so-called ‘experts’ such as Dr. Benjamin Neuman, (not a medical doctor) who says “Breathing from saunas or a hair dryer would not have any effect on preventing or treating coronavirus, and both are downright weird”, and Health Analytics Asia which states: “Our body temperature ranges between 36.5 to 37.5 degrees Celsius and hot showers or liquid won’t change this temperature.” While these sites have an air of authority and any social media posts that contradict these statements are censored and removed from Facebook, YouTube etc for “violating their community guidelines”, these statements are blatant lies.
You don’t have to take my word for it. Anyone with a hot bath and a thermometer can prove the WHO is lying. There are also multiple studies that demonstrate an increase in core body temperature of 1-3 degrees occurs when bathing in hot water [1-6] and with the use of an infrared saunas  or Finnish saunas  and there is a wealth of research showing an increase in body temperature can boost immunity. The lies about heat represent dangerous misinformation as they prevent people from using cheap, effective and widely available interventions, and give the impression there is no way to enhance your own immunity and must therefore wait in fear until a vaccine is available.
This is certainly not the case.
In response to the attacks on me from social media trolls and the false and misleading statements being put out by the WHO and other health authorities, I wrote a scientific peer-reviewed paper that reviews the evidence for using heat to treat COVID-19. This paper titled “Turning up the Heat on CoVID-19: heat as a therapeutic intervention” documents the evolutionary, historical, epidemiological, clinical, laboratory, and randomised controlled trial evidence that shows raising your body temperature using baths, steam-rooms, saunas or other hydrothermal therapies is an effective way to overcoming viral pathogens. Furthermore, when used regularly, heat treatments not only prevent respiratory viral infections, they also prevent most chronic diseases such as cardiovascular disease and Alzheimer’s disease and reduce all-cause mortality.
Before you go about disproving the WHO statements for yourself, be aware that even though hydrothermal therapies are very safe and effective, and do not require specific medical supervision or prescription, heat is a powerful force and like any powerful intervention it has the potential to either hurt or help you. There are, therefore, some common-sense safety principles that need to be followed when raising your body temperature using heat treatments.
These common-sense safety principles include:
- Drink: Ensure adequate hydration with a good quality water is maintained and safe physiological limits are not exceeded;
- Take care: Avoid burns or scalds near sources of heat and sudden changes in posture that could lead to dizziness or fainting;
- Know your limits: Use your comfort level as a guide to safe exposure. Do not to go beyond the point where you are ‘comfortably uncomfortable’. Heat tolerance varies widely between individuals and within the same individual at different times. It is important to gently explore your limits and not force yourself beyond the state of ‘forced mindfulness’;
- Be aware: Tune into your senses and monitor your tolerance. Avoid extremes of temperature when under the influence of alcohol or drugs that impair your judgement;
- Rest: Alternate exposure to hot or cold with re-balancing periods. Spend at least as much time resting and coming back into physiological balance as spent in extremes of temperature.
Hydrothermal therapies let you receive the benefits of fever without the metabolic cost by outsourcing the generation of heat to the environment. These therapies not only activate your immune system, they also activate your biochemistry, physiology and psychology and serve to create community cohesion and wellbeing, as they’ve done since time immemorial. In addition to simulating fever and boosting the immune system, heat also directly inhibits and destroys viruses, and is now used to sterilise police cars in the US, which are heated to 55 degrees for 15 minutes to destroy coronavirus.
Since publishing my peer-reviewed paper up on heat, I have also published a post on how saunas are a solution to helping your body and mind overcome COVID-19, and a position paper on why hydrothermal therapies need to be considered ‘essential services’ during a pandemic. Yet, while this paper has been published by the Global Wellness Institute’s Hydrothermal and Hot Spring Initiatives and the World Federation of Hydrotherapy and Climatotherapy (FEMTEC), and has been translated into Russian and Chinese and sent to various government health officials around the world, government restrictions have closed down public bathing and sauna facilities, and denied people access to beaches and natural water sources, despite them being the safest, healthiest and most desirable places to be during a pandemic.
Water is the most basic requirement for life and bathing is the cheapest, simplest and most effective health intervention on earth. Bathing offers global health benefits beyond any pharmaceutical drug, vaccine, or any other medical technology. If the money currently being spent on vaccines was spent on clean water, then most infectious diseases in the world would be eradicated, and global health would be boosted to a level where we could all travel freely without fear of infection. Our security would then come from the health and prosperity of all people, rather than power enforced through a military-industrial complex and it’s chemical, nuclear, biological, cyber and psychological weapons.
Yet, before we can bathe the world, we will first need to win the information war that is waged on us by authorities willing to promote brazen lies that anyone with a thermometer can expose.
