πŸ” Wisdom Unpacked

Delving deeper into the key ideas.

1. Mind and body practices enhance immune function and recovery.

The mind and nervous system play a crucial role in controlling the immune system's function. Adequate sleep, sunshine, exercise, and a balanced diet are foundational practices to enhance immune function. Additionally, specific actions like elevating the feet during sleep, supplementing with 5-HTP or tryptophan, and stimulating specific areas of the body can further boost the immune system's response. These actions can enhance the function of the immune system and promote faster recovery from illness and injury.

2. Immune system defense involves physical barriers, rapid response, and specific targeting.

The immune system has three main layers of defense: the physical barrier of the skin, the openings to the body, and the mucus lining of the tubes. The innate immune system, the second layer, involves the rapid response to invaders, while the adaptive immune system, the third layer, involves the recognition and targeting of specific invaders. The immune system also includes different cell types that actively go to the site of invasion and try to surround and kill the invader. The adaptive immune system recognizes and attaches to the shape of invaders, creating imprints and producing antibodies specific to them, creating a memory of prior infections. To keep the defense systems against infection tuned up, it is important to maintain a healthy mucus lining and promote a healthy microbiome.

3. Boost immunity by nasal breathing, avoiding eye contact, and consuming fermented foods.

The nasal microbiome is a powerful tool in combating infections, particularly through nasal breathing. It's crucial to avoid touching your eyes after touching other people or surfaces, as this can be an entry point for bacteria and viruses. To enhance the health of your mucus tract, consume fermented foods like sauerkraut and kimchi, which reduce inflammatory cytokines and promote a healthy gut microbiome. Additionally, keep your hands clean, be a nasal breather, and avoid wiping your eyes. These practices can boost your immune system and combat infection.

4. Sickness behavior and major depression share similarities and can be influenced by behavioral patterns.

Sickness behavior, a natural response to illness, involves a slowing of activity, loss of grooming, and loss of appetite. This behavior is designed to combat infections and promote healing. It's a motivated state that slows blood circulation, increases lymph circulation, and reduces the probability of infecting others. Sickness behavior and major depression share similarities in terms of increased levels of inflammatory cytokines, suggesting that interventions targeting these cytokines could help prevent or alleviate illness. Certain patterns of thinking and behaviors can enhance our immune system function, such as reducing iron intake. Loss of appetite is common in both sickness behavior and major depression, suggesting a connection between the two.

5. Vagus nerve triggers body response to infection, altering perception and promoting rest.

The vagus nerve, a key player in the body's autonomic nervous system, plays a crucial role in the body's response to infection or injury. It triggers the sickness behavior pathway, which includes the fever response and increased body temperature to kill off the invader. The vagus nerve also sends signals to the brain, altering our perception of the outside world and leading to symptoms like photophobia and headaches. Additionally, it triggers the desire to rest and sleep, which is also regulated by the hypothalamus.

6. Sickness involves inflammatory pathways in the body and brain.

When you're sick, your body and mind work together to avoid light and reduce behavior, aided by two pathways. The fast pathway involves inflammatory cytokines like IL-6 and IL-1, which increase in your circulation and communicate to the brain, causing inflammation and changes in cognition. The slow pathway involves tissues in the brain called choroid, which release inflammatory signals. Both pathways help the brain cope with the infection.

7. Hot showers and saunas can combat infection, but 'starve a cold' is still mysterious.

Taking a hot shower or using a sauna can help combat infection by increasing body heat, which can be beneficial for combating infection. However, it's important to avoid getting into a sauna if you already have a fever. The phrase 'feed a fever, starve a cold' may have originated from the adaptive function of fever, which increases body temperature and makes it challenging for intruding viruses and bacteria to survive. Eating increases body temperature through the thermogenic effect of food, supporting the 'feed a fever' part. However, the 'starve a cold' part is still mysterious and lacks logical reasoning.

8. Sympathetic nervous system activation enhances immune function.

Research suggests that the sympathetic nervous system, associated with epinephrine release, can enhance immune function and combat infection. This is evident in a study that found a behavioral protocol involving cyclic hyperventilation and breath retention increased the release of anti-inflammatory cytokines and reduced the release of pro-inflammatory cytokines. The study also showed that the sympathetic nervous system plays a role in enhancing immune function and combating infection. Additionally, a recent study explored the neuroanatomical basis for electro-acupuncture to drive the vagal adrenal axis. The study found that stimulation of the body with electro-acupuncture can increase inflammation, while stimulation of the lower limbs can activate nerve endings in the fascia and stimulate the vagal adrenal reflex, leading to reduced inflammation. This understanding can lead to the development of new and more effective protocols, such as breathing techniques that can be done anywhere and anytime.

9. Thoughts can directly influence our physiology, potentially causing illness.

Our thoughts can directly influence our physiology, potentially making us sick. This is evident from research showing that psychogenic stress can activate a corticolimbic pathway in the brain, leading to fever and illness-like behavior. This pathway originates in the cortex and feeds into the hypothalamus, which controls basic physiological processes. By associating certain stimuli with stress, subjects can activate this pathway and experience symptoms even in the absence of a traumatic event. Blocking certain stations along this pathway can prevent the illness-like behavior, suggesting that our thoughts can directly impact our health.

10. Hope and dopamine stimulation can accelerate recovery from illnesses.

The sense of hope, associated with the dopamine system, can significantly impact recovery from illnesses and injuries. This system, responsible for reward, motivation, and movement, can be stimulated by thinking about a positive future, reducing the size of tumors, accelerating wound healing, and promoting recovery. Augmenting the dopamine system can also increase the rate of healing. However, it's crucial to consult with a doctor before taking any supplements or engaging in activities that increase dopamine. The dopamine system, when activated, can accelerate healing by reducing inflammatory cytokines and increasing anti-inflammatory cytokines. Cold water exposure and breathing techniques can also increase dopamine levels and enhance the function of the immune system.

11. Spirulina reduces rhinitis symptoms by inhibiting mast cells.

Spirulina, a form of algae, has been found to reduce symptoms of rhinitis and inflammation of the nasal passages. It can inhibit the formation and/or activity of histaminergic mast cells, which contribute to rhinitis. Mast cells, containing histamine, release it when there is an injury or irritant, causing swelling and inflammation. Spirulina can be used effectively to treat seasonal allergies by reducing histamines in mast cells. However, it can be a problem for people with a genetic mutation called PKU. Spirulina can have minimal side effects for most people.
