Health Devices

Photobiomodulation · Panels & LED Masks

Real mitochondrial mechanism, genuine skin and soreness signals, marketing that sprints ahead of the data.

Photobiomodulation (PBM) deviceNo FDA approval for general red light wellness claims. Specific devices hold 510(k) clearances for narrow indications: Joovv Generation 3.0 panels are 510(k)-cleared Class II devices; many LED masks (certain Omnilux, CurrentBody units) carry 510(k) clearances for wrinkles or acne. Most at-home panels are sold as general-wellness products with no clearance. Clearance signals reasonable safety and substantial equivalence, not proof of efficacy.

Sauna Bathing · Finnish & Infrared Heat

The strongest human longevity signal for any heat protocol comes from one Finnish town followed for two decades.

Passive heat therapySaunas are sold as general wellness products and are not FDA-cleared to treat, prevent, or cure any disease. No medical device clearance underwrites the heart-health or longevity claims marketed by manufacturers.

Cold Water Immersion · Ice Baths & Plunge Tubs

Real recovery and mood signals, but skip the ice bath right after lifting if muscle is your goal.

Thermal recovery practiceNot an FDA-regulated medical treatment. Cold plunge tubs and chillers are sold as general wellness or recreational products, not cleared devices, and carry no approved disease claims.

Hyperbaric Oxygen · Pressurized O2 Therapy

Pressurized oxygen with ~14 solid medical uses; the home soft-chamber wellness boom rests on far thinner evidence

Pressurized oxygen therapyFDA clears HBOT chambers as Class II devices via 510(k). UHMS lists ~14 to 17 approved indications (decompression sickness, CO poisoning, gas gangrene, radiation injury, diabetic foot ulcers, sudden hearing loss). Anti-aging, autism, long-COVID and sports recovery are off-label; FDA has warned that unproven uses can delay real care.

Oura Ring · Smart Sleep & Recovery Ring

Finger-worn ring that infers sleep stages, HRV, temperature trends and a daily readiness score

Smart ring wearableGeneral wellness device, not FDA-cleared for diagnosis; Oura pursuing FDA pathways for blood-pressure and metabolic features as of 2025

TENS · Electrical Pain-Gating Therapy

Skin-surface electrical stimulation that aims to dampen pain signaling; mechanism is well grounded, clinical results vary

Electroanalgesia deviceFDA Class II under 21 CFR 882.5890; cleared via 510(k). Available both over-the-counter (general and arthritis pain) and by prescription. New units clear on substantial equivalence, usually without fresh efficacy trials.

Whoop · Strain & Recovery Band

Membership-only wrist band that turns nightly HRV and heart rate into proprietary recovery, strain and sleep scores

HRV recovery wearableWHOOP MG ECG software got FDA 510(k) clearance (K243236, April 2025) for AFib detection; a July 2025 FDA warning letter says the Blood Pressure Insights feature lacks clearance. Core strain and recovery scores are unregulated wellness features.

Zone 2 Training · Aerobic Base Method

Training mostly below the first lactate threshold to build aerobic base, fat oxidation and mitochondrial capacity

Endurance training methodNot a regulated product; exercise training method, no FDA oversight.

Continuous Glucose Monitor · 24/7 Skin Sensor

A coin-sized arm patch that streams your blood sugar to your phone every few minutes.

Metabolic wearable sensorFDA-cleared as a medical device. Stelo by Dexcom cleared March 5, 2024 as the first OTC glucose sensor in FDA history; Abbott Lingo and Libre Rio cleared June 10, 2024. Prescription CGMs for diabetes long predate these OTC clearances.

Pneumatic Compression · Recovery Boots

Air-pumped sleeves that squeeze the limbs in waves; modest help for soreness, weak evidence for real performance gains

Mechanical recovery deviceMedical IPC pumps hold FDA 510(k) clearance for lymphedema, venous ulcers and DVT prophylaxis; consumer athletic recovery boots use the same mechanism but their faster-recovery and performance marketing claims sit outside any cleared indication.

PEMF · Pulsed Magnetic Fields

Real clearances for stubborn fractures and spinal fusion; the glowing wellness mat is a different, weakly-supported product

Electromagnetic stimulationFDA cleared/approved ONLY for narrow uses: bone-growth stimulators for fracture nonunion (Class III PMA, 1979) and as a lumbar spinal-fusion adjunct; ActiPatch 510(k)-cleared 2017 for knee OA and plantar fasciitis. Consumer wellness mats (HealthyLine, Bemer) are at most FDA-listed, which is NOT clearance and certifies no efficacy.

Wim Hof Method · Breath, Cold & Commitment

Cyclic over-breathing, breath holds and cold exposure. One real immune study; most claims still outrun the evidence

Breath and cold protocolNot an FDA-regulated product; no drug or device clearance. Marketed as wellness training, not medical treatment.
