Longevity and Immunity
The Remedies (17)
Longevity Protocols
An overview of healthspan strategies studied in aging research, including fasting, exercise, sleep, nicotinamide adenine dinucleotide (NAD+), rapamycin, metformin and senolytics.
Read the deep dive →Oxidative Stress
The imbalance between free radicals and antioxidant defenses, its links to chronic disease, lab tests for it, and trials where antioxidant supplements backfired.
Read the deep dive →Immune Boosting
A naturopathic regimen built around vitamin D, zinc, vitamin C, mushrooms, elderberry, gut health and sleep, with cautions for autoimmune conditions.
Read the deep dive →Salt In Socks
A viral folk remedy of salt-filled socks; warm feet aid sleep, the salt adds little, and it poses risks for diabetic feet.
Read the deep dive →Cold Exposure
Cold showers, ice baths and winter swims, studied for recovery, mood and metabolism, with the cold-shock drowning risk flagged first.
Read the deep dive →Senolytics
Drugs designed to kill worn-out senescent cells; striking in mice, but human trials remain small, early and unproven for slowing aging.
Read the deep dive →Sauna
Regular heat bathing, mostly the Finnish kind, which large Finnish studies link to lower rates of heart disease, dementia and death.
Read the deep dive →Hyperbaric Oxygen
Breathing pure oxygen in a pressurized chamber, well established for a short list of serious conditions but marketed for many unproven uses.
Read the deep dive →Cold Flu Treatments
A naturopathic approach to colds and flu covering zinc lozenges, elderberry, vitamin C, steam, rest, fluids and signs that need a doctor.
Read the deep dive →Cryotherapy
Cold used as treatment, from ice packs and whole-body chambers to surgical freezing, with evidence ranging from well established to thin.
Read the deep dive →Brain Aging
A look at how neurons, blood vessels and sleep change with age, and which modifiable risk factors studies link to dementia.
Read the deep dive →Grounding Earthing
Bare skin on the earth, or wired indoor mats, claimed to pass calming electrons into the body; researchers describe the evidence as weak.
Read the deep dive →Float Therapy
Floating in warm, heavily salted water with light and sound shut out, studied in small trials for stress, anxiety, pain and sleep.
Read the deep dive →Hydrotherapy
Using water's warmth, cold, buoyancy and pressure, from the Kneipp tradition to therapy pools, with the strongest evidence for warm-water exercise in arthritis.
Read the deep dive →Forest Bathing
Japan's shinrin-yoku, slow mindful time among trees, studied mainly for stress hormones, mood and blood pressure, plus an immune-cell finding.
Read the deep dive →Contrast Therapy
Alternating hot and cold, from contrast baths to sauna and plunge, used for workout recovery and swelling, with modest supporting evidence.
Read the deep dive →Red Light Therapy
Red and near-infrared light aimed at the skin, studied for wrinkles, hair loss, muscle pain and mouth sores during cancer care.
Read the deep dive →Prescription and over-the-counter drugs now have their own section: Pharmacology › Drugs.
Thermal and environmental exposures, and the pharmacological and protocol-level attempts at slowing ageing. The longevity drugs here rest largely on animal data, which the pages state plainly rather than extrapolating.
A remedy is filed here by what it claims to do, not by a judgement that it works. This section deliberately covers practices whose own pages conclude they do not — read the page before the category name.
