All protocols

Supplement vitamin A only when dietary intake is likely insufficient or a deficiency risk is present; for most people, food sources are enough. Small amounts included in a foundational or multivitamin formula are generally considered fine, but routine high-dose standalone use is usually unnecessary and can raise toxicity concerns.

A structured rehabilitation approach that uses purposeful daily activities to help the brain and nervous system relearn function after injury or illness. It can be paired with vagus nerve stimulation to amplify neural activation during therapy sessions, with the goal of improving recovery and functional independence.

Spend regular time outdoors in natural settings with trees, shrubs, grass, and other greenery, especially forest-like environments. The idea is that these spaces can act as a biological and psychological reset, with proposed benefits including lower inflammation and mortality, potentially helped by greater exposure to infrared-reflecting vegetation.

Keep blood glucose well controlled, with attention to maintaining a good hemoglobin A1c. This is recommended to lower the risk of diabetic retinopathy and to reduce diabetes-related inflammation and damage to white matter and the hippocampus, which may also help protect against Alzheimer’s-related decline.

A closed-loop training method that uses real-time feedback to help you learn how to downshift sympathetic nervous system arousal, especially during pain. By practicing control over signals like breathing, heart rate, or muscle tension while monitoring the feedback, you can build better self-regulation and reduce the body’s stress response.

This is the practice of addressing problematic alcohol use directly, either by gradually cutting back or stopping altogether. The common thread is to choose a deliberate reduction plan rather than letting heavy drinking continue, while recognizing that anxiety and stress can rise during the transition. A structured approach helps people move out of a harmful pattern more safely and with better odds of sticking with it.

Keep your body moving throughout the day rather than sitting for long stretches, with walking as the main tool and a practical floor of about 7,000 steps daily. The goal is to reduce stagnation and support lymphatic flow, making movement a steady background habit instead of a single workout.

Use stevia in place of sugar or other sweeteners when you want sweetness without meaningful calories. It is generally treated as having little to no effect on blood glucose and, based on the cited recommendations, does not appear to harm the gut microbiome. The appeal is a naturally sourced sweetener that can reduce sugar intake without the usual metabolic downside.

Using hearing aids to correct hearing loss, especially when it is present and functionally meaningful. The idea is to restore auditory input early and consistently rather than “toughing it out,” because untreated hearing loss is linked to faster cognitive decline. Better hearing may reduce cognitive load and social isolation, which is why it’s often framed as a practical step for lowering dementia and Alzheimer’s risk.

Take a short walk every day as a simple baseline movement practice, aiming for about 20 minutes when possible. Keep the pace easy and stop short of aggravating pain or injury. This low-friction routine helps maintain mobility and circulation while making it easier to stay consistent with movement even during recovery.

A rehab approach that uses targeted physical therapy after injury to help restore movement and function. In the cited protocol, it’s paired with vagus nerve stimulation to better activate neural pathways, which may improve recovery outcomes beyond standard rehab alone.

Generally keep high-glycemic and high-sugar foods out of your regular diet, especially away from the post-workout window. The idea is to reduce repeated large insulin and blood-glucose spikes, which may help lower acne-promoting signaling through pathways like mTOR, androgens, sebum production, and keratinocyte activity.

A morning supplement routine using green tea in capsule form, typically taken as a couple of capsules after waking. It’s used as a convenient way to capture green tea’s bioactive compounds without brewing tea, often for a mild stimulant and antioxidant effect that supports alertness and general metabolic health.

A generally lower-carbohydrate eating pattern built around minimally processed foods, with carbs reduced but not eliminated. The emphasis is on whole foods and avoiding inflammatory, highly refined items to support steadier blood sugar and better insulin sensitivity, which can be especially helpful for PCOS.

Aspirin is a common over-the-counter pain reliever used for headaches, typically taken at the first sign of pain. It can reduce headache discomfort by dampening inflammation and pain signaling, but it may be a poor choice for migraine in some people because migraine can involve blood-vessel changes that aspirin may not address well.

Use a steam room or steam sauna after cold exposure, or whenever your nasal and oral passages feel dry. The goal is to raise core and skin temperature enough to drive heat exposure while the moist air helps rehydrate irritated airways and passages.

For night-shift workers, wear sunglasses or otherwise avoid bright light on the way home and before sleep. Reducing light exposure after a nocturnal shift helps prevent your brain from getting a daytime wake-up signal, making it easier to fall asleep and recover.

Licorice root is used in very small doses to help raise cortisol, which can be useful when someone is trying to support low stress resilience or adrenal output. Start with the lowest possible capsule dose because it can be potent, and avoid it during pregnancy, breastfeeding, or if you have high blood pressure.

Limit contact with common environmental chemicals and contaminants in your food, water, air, and household products. The practical goal is to avoid unnecessary exposures by choosing cleaner inputs and safer surroundings, which can reduce the body’s toxic burden and lower the chance of getting sick over time.

Include fruit as part of an overall whole-food diet, rather than avoiding it outright. For people at higher risk of tooth decay, it may be wise to limit fruit intake or be more mindful of frequency because its fructose exposure can contribute to dental caries risk.

A steady run of about 3 miles, used as a regular aerobic session rather than an all-out workout. The practice is valued for its mental effects: it can improve mind wandering, creativity, and problem solving, and may also make intrusive or compulsive feelings seem less immediate.

Deliberately build in periods of true rest that shift the body out of stress mode and into parasympathetic recovery. This can mean quiet downtime, lying down, slow breathing, or other low-stimulation pauses that let the nervous system downregulate. The goal is to restore baseline function and support overall health by reducing chronic physiological strain.

Use behavioral speech therapy techniques that slow and stabilize speech, such as speaking more deliberately, tapping out a rhythm, and adjusting auditory feedback. These sensory-motor strategies help coordinate timing and articulation, which can reduce stuttering and improve fluency.

When you feel sleepy or mentally sluggish, tilt your eyes upward toward the ceiling and hold that gaze for about 10–15 seconds. This simple eye position can help trigger wakefulness-related circuits and briefly increase alertness.

Use a Snellen eye chart at home as a simple visual-training tool, checking your distance vision regularly and practicing the chart as part of a structured routine. The idea is to give your eyes repeated, measurable focus work, which may help track changes in acuity and support visual training over time.

Eat naturally occurring vitamin A sources such as dark leafy greens and carrots, ideally in as close to their raw form as practical. This helps preserve nutrient content while supporting adequate vitamin A intake, which is important for maintaining healthy vision and preventing deficiency.

Get a professional eye exam when you need an accurate prescription or are considering corrective lenses or laser surgery. An ophthalmologist is especially useful for severe eye problems or significant differences between the two eyes, because a detailed measurement can catch issues that a basic screening may miss and helps ensure the right treatment choice.

Perform repeated high-intensity anaerobic intervals in sets of about 3–12, typically 1–3 times per week. Keep the work-to-rest ratio anywhere from roughly 3:1 to 1:5, adjusting pace so each effort can be completed with good, safe form. This builds anaerobic endurance by training the body to sustain hard efforts and recover quickly between bursts.

Deliberately raise or lower body temperature to influence your state across the day. Warming yourself tends to promote alertness and wakefulness, while cooling down helps the body transition toward sleepiness and sleep onset. The basic mechanism is that temperature changes act as a circadian cue, nudging arousal up or down.

Use humming as a calming breathing-and-vibration practice, often by emphasizing the "h" sound so the vibration feels more in the back of the throat than the lips. The idea is that the sound mechanically engages vagal branches around the larynx, which may help downshift the nervous system and promote relaxation; some discussions also note a vasodilating effect.
