Fever

Aajonus described a precise set of temperature thresholds at which different biological processes stop or start, and understanding these thresholds is essential to his framework for fever.

At approximately 99.7 degrees Fahrenheit, mold can no longer breathe or proliferate in the human body.

At 100 degrees Fahrenheit, bacteria stop reproducing entirely. No bacteria colony can grow or spread at or above this temperature. Aajonus stated this threshold multiple times in his workshops and consistently emphasized that this is the baseline temperature at which the body gains control over its bacterial environment. He also placed the cessation of viral production at approximately 100 degrees, stating that cells stop manufacturing virus at around this point, though he identified the threshold for stopping viral multiplication more precisely at 101 degrees in some passages.

At 100.2 degrees Fahrenheit, parasites cannot reproduce.

At 102 degrees Fahrenheit, cellular division accelerates significantly. Aajonus described this as the temperature at which cells begin dividing rapidly, provided that adequate nutrients are available. He compared the heat generated by this rapid cellular division to the heat produced during sexual activity, noting that both processes involve the same kind of rapid cellular multiplication and generate warmth as a byproduct.

Fungus, in one passage, is treated somewhat differently. Aajonus stated that while bacteria, parasites, and molds cannot grow above 100 degrees, fungus can still multiply. This is one of the few distinctions he drew between different categories of microbe in relation to temperature thresholds, and it represents a point of nuance within his broader teaching that fever halts detoxification microbes.

At 104 to 106 degrees, the healing process is operating at maximum intensity. Aajonus stated that he had seen children on the Primal Diet reach fevers of 106, 106.2, and even 106.5 degrees without any resulting brain damage, and that in fact these children went on to demonstrate exceptional cognitive development. He cited a child who entered fourth grade at age five and a seventeen-year-old who had just graduated from Yale after being placed on the diet at one year old, and connected their intellectual development explicitly to having experienced high fevers during their healing processes.

Aajonus drew a clear distinction between two phases of what the body is doing during an illness. The detoxification phase, which can last many months or even up to two years, is the period during which bacteria, parasites, fungus, and viral activity work to break down damaged, degenerate, or toxic tissue. This phase is mostly invisible from the outside. What people call a cold or flu is not this phase. It is the end of this phase, when the breakdown products that have been accumulating in lymph nodes and glands are suddenly released and expelled through mucus, sweat, vomiting, and diarrhea.

Fever arrives at this transition point. When the body reaches 100 degrees, the detoxification processes are shut down. Aajonus described this as the body saying, in effect, that it is done cleaning and is moving into repair. Because detoxification generates toxic byproducts, the fever also serves the purpose of ensuring that all those broken-down substances have been cleared away before cellular reconstruction begins, so that the healing process is not contaminated by residual poisons.

He described one specific case of a person who went on the diet and felt great initially, then entered a seven-week detox period, and finally emerged from it with a fever accompanied by mucus and other discharge. The actual bacterial activity had been running for the entire seven weeks; the visible symptoms and fever appeared only at the end, which is why Aajonus repeatedly stressed that the healing crisis is called a healing crisis rather than a detox crisis.

Night fevers and night sweats receive specific attention in his writing. He described them as "usually a combination of friction from mass cellular division (cellular reproduction) and cessation of intense detoxification," and characterized them as "cause for joy," a sign of intense rejuvenation in which the body is producing new cells.

Aajonus's explanation of why fever supports healing centers on the relationship between elevated temperature and the rate of cellular reproduction. He explained that when body temperature climbs to 102 degrees, cells begin dividing rapidly, and this rapid division itself generates additional heat. This is why fevers tend to escalate. The process is self-reinforcing in a productive direction as long as nutrients are available to support it.

He described the situation using the analogy of sex: when people have sex and generate body heat, what is actually occurring at the cellular level is rapid cell division. Fever creates the same physiological condition systemically. The implication is that suppressing fever with pharmaceutical drugs is the equivalent of shutting down the body's primary mechanism for growing new tissue.

At 102 degrees and above, Aajonus stated, cellular division becomes fast enough to produce meaningful tissue regeneration, but this speed depends on nutritional availability. This is why he recommended specific foods during fevers rather than medical suppression. The body must have adequate raw fats, proteins, and minerals to execute the cellular reproduction that fever facilitates.

Aajonus was direct and consistent in his condemnation of the medical response to fever. He identified three categories of pharmaceutical intervention that suppress fever: antibiotics, analgesics, and sulfur-based compounds. Each of these, in his framework, terminates the healing crisis artificially, preventing the body from completing its repair cycle and leaving the person to age and deteriorate faster as a result.

He stated that if fever is suppressed, the healing that would have occurred during that period simply does not happen. The person will, as he put it, "get old and feeble" and will fail to repair what needed repairing. The damage from suppression is not immediate or dramatic but cumulative, representing every healing opportunity that was aborted by pharmaceutical intervention.

He drew a direct comparison in healing speed. A person who rides out a fever without suppression will, in his description, be back to full function within approximately one week, sometimes in a few days on the Primal Diet. A person who takes aspirin and other suppressive drugs will typically take around six weeks to return to the same baseline, and even then will not have completed the cellular regeneration the fever would have provided.

On antibiotics specifically, Aajonus made a more severe argument. When a child with a fever of 102 is given antibiotics, the digestive tract is devastated. He stated that the growth of beneficial bacteria in the infant digestive tract is arrested for at least four to five years, and that this arrested development directly impairs the mental capabilities of the child, because the gut-brain relationship depends on a healthy microbial ecosystem in the digestive system. He described the loss of digestive function from antibiotic exposure as depriving the child's brain of the biological infrastructure it needs to develop fully.

He also described the medical practice of packing patients in ice, which he experienced personally, as something that causes a "brain hemorrhage" through thermal shock and constitutes genuine trauma rather than treatment. Ice suppresses the healing process not by addressing any underlying condition but by forcing the body's temperature back down mechanically, which prevents cellular division, allows bacteria and parasites to resume proliferating, and leaves the patient worse off at a biological level than before the treatment.

The medical argument for suppressing fever rests primarily on the fear of brain damage, and Aajonus addressed this directly and repeatedly. He characterized the claim that fever causes brain damage as "myth and fiction," and stated that in his experience with large numbers of people who had had fevers, including very high fevers in infants and children, he had not encountered a single case of fever-induced brain damage in people eating a raw diet.

He qualified this position in an important way: he consistently attached the safety of high fevers to the condition of eating a predominantly raw diet. He stated that "convulsion and irreversible brain damage has not happened from fever" when the person is eating predominantly raw food. His explanation for why the raw diet changes the outcome involves the availability of nutrients, the absence of processed chemical residues, and the clean biochemical environment that raw food creates, all of which allow the fever to run its proper course without generating secondary complications.

Children on the Primal Diet, in his experience, not only survived fevers of 106 degrees without damage but demonstrated superior cognitive outcomes compared to children whose fevers were suppressed. The children he described as having gone through high fevers were the same children he pointed to as examples of exceptional intelligence and accelerated development.

A central practical implication of Aajonus's fever framework is his use of hot baths as a deliberate method for inducing a fever-like state without waiting for the body to generate one spontaneously. He described this approach explicitly, noting that hot baths produce "the same effects produced by fever" in terms of relaxing bacteria into hibernation and discouraging cells from producing virus.

The lymphatic bath protocol he described requires water temperature maintained between 102 and 105 degrees Fahrenheit for sixty to ninety minutes. He emphasized that the body must be fully immersed, because when immersed in water at this temperature the body cannot cool itself through air circulation, meaning internal temperature actually rises in a way that exercise or sauna cannot replicate. Even extreme athletic exertion, in his description, never raises internal body temperature above 100 degrees, which is why exercise alone cannot achieve the lymphatic melting and cellular division that a properly executed hot bath can produce.

The mechanisms at work in the hot bath, as Aajonus described them, are specifically the melting and liquefaction of congested lymphatic material, the softening of hardened and crystallized fats stored in the lymphatic system, and the initiation of the same cellular division that fever induces. He recommended 45-minute baths for daily detoxification of the material just under the skin, and 60 to 90-minute baths for reaching the deeper lymphatic glands and nodes, noting that it takes approximately 60 minutes of immersion before the heat begins to melt the congestion deep in the lymphatic system, after which a further 30 minutes are needed to liquefy enough material to allow it to be perspired out.

Aajonus's practical guidance for managing fever is built around supporting rather than suppressing the process, with specific foods and behaviors that either sustain the healing cycle or, in cases of extreme distress, bring the temperature down moderately without destroying the healing mechanism entirely.

For general support during fever, he recommended raw cream mixed with raw carrot juice, or raw cream mixed with orange or watermelon juice, describing these as "often the most soothing." He also recommended getting plenty of sleep, fresh air, and sunshine, stating that "most healing occurs during those states."

He recommended eating plenty of raw meat during and after fever cycles, connecting this specifically to the need for protein to support rapid cellular division. He mentioned eating one eighth teaspoon of royal jelly with raw meat and raw fat daily during fever cycles to increase the body's ability to reproduce and strengthen cells.

For a fever reaching 105 degrees or above, he gave a specific protocol: drink chilled fresh blended raw tomatoes, or fresh raw fruit purees made from red and orange raw foods. He also described a formula specifically for infants: two ounces of fresh raw celery juice, one ounce of fresh raw carrot juice, one ounce of fresh raw tomato puree, and one raw egg, which he said keeps fever at a comfortable temperature without danger. Applying moist cool compresses (not cold compresses) to the forehead was also mentioned as a way to reduce fever in the head when it reaches 104 to 105 degrees.

He gave a recipe from We Want to Live for managing very high fevers specifically through the tomato drink on page 263, and recommended smoothies and milkshakes over juices during fever, noting that juices tend to cause more detoxification rather than supporting the healing state. He mentioned that eating a small amount of cheese often helps during this period because the minerals in cheese are needed to handle the large quantity of toxic fluid being moved through the body during viral detoxification.

For parents who find themselves panicking over a child's high fever, Aajonus recommended feeding tomatoes or other items from his fever-reducing protocol as a way to bring the temperature down slightly, for example from 106 down to 105 or lower. But he consistently framed this as a concession to parental anxiety rather than a medically necessary intervention, and he was explicit that lowering the fever slows the healing process and that the child will not recover as quickly as one whose fever is allowed to run.

He also suggested, for those who struggle with the heat of fever, a practical cooling measure: a bowl of cold water with ice cubes and a washcloth placed on top of the head, with open fists immersed in the water when the heat becomes distressing, as an alternative to suppressing the fever pharmaceutically.

Aajonus recommended that during fever a person should ride it out "like it's a hot day," covering themselves with hot water bottles, wearing warm clothing to sweat it out, and treating the sweating as productive work the body is doing rather than a symptom to be relieved. He described this approach as comparable to having no air conditioning for a couple of days and simply enduring the heat, noting that the payoff is rapid and deep cellular regeneration.

Aajonus applied his fever framework broadly, including to conditions such as malaria and rheumatic fever, which conventional medicine treats as diseases requiring aggressive pharmaceutical suppression of fever.

In his newsletters, he described malaria symptoms as flu-like and characterized fever in that context as "always the body reducing detoxification and initializing a healing cycle," adding that the lethargy following such fevers can last from one to twenty weeks. His recommendation for managing fever in this context included eating no-salt-added raw cheese and clay to draw poisons from the blood into the stomach and intestines.

Rheumatic fever, in his framework, is described as a detoxification of connective tissue linking muscles, cartilage, and bone, occurring mainly in children ages four to eighteen whose lymph systems are impaired. He connected it to vaccine exposure, antibiotic use, medications, and toxins consumed by the mother during fetal development, and stated that when a wholesome raw diet was not maintained during the process, the RNA and DNA sustained further damage, leading to residual conditions including heart disease, arthritis, and tissue problems.

One of the practical claims Aajonus made about fever is that the Primal Diet dramatically shortens the duration and intensity of the fever cycle. He described people on his diet recovering from flu in a few days rather than weeks, attributing this to the availability of raw fats and proteins to support rapid cellular division during the fever, as well as to the cleaner biochemical environment that raw food creates.

He contrasted this with people who suppress fever through pharmaceutical means, whose recovery stretches to approximately six weeks, and he attributed the prolonged recovery not to the illness itself but to the interruption of the healing cycle. The illness essentially has to restart or continue at a lower level, without the benefit of the elevated cellular division rate that fever enables, and so progress is slow and incomplete.

For people on the Primal Diet who have already cleared significant stored toxins, the healing crisis itself may be shorter and less severe, because there is less accumulated material waiting to be released. This is consistent with his broader teaching that long-term raw eating reduces the size and frequency of detoxification events by giving the body adequate resources to process toxins gradually and continuously rather than accumulating them for a massive periodic purge.
