This is the EMF Channel database of light therapy study doses. After getting the results, click to view more study details. Only successful studies are included. 99% of the studies here are on humans, not animals. This database is a work in progress. Many thanks to Vlad for his PBM database. When the data here references his work, the detail page includes a link to the PBM spreadsheet.
Amber Light (590 nm) Induces the Breakdown of Lipid Droplets through Autophagy-Related Lysosomal Degradation in Differentiated Adipocytes
Researched irradiated human fat with 410 nm, 457 nm, 505 nm, 530 nm, 590 nm, and 660 nm low level light. 590 nm “significantly reduced the concentration of lipid droplets” and increased lipid autophagy (broke down fat). In documenting the science of photobiomodulation, I rarely come across a study that finds significant effect at one wavelength, and no effect at nearby wavelengths. That did happen in this study. 590 nm affected fat breakdown and 505 nm did not. The abstract did not mention the other wavelengths tested. Presumably they were also insignificant, so it’s unclear why 505 nm was singled out as ineffective.
A double-blind, placebo-controlled randomized trial evaluating the ability of low-level laser therapy to improve the appearance of cellulite
Use green 532 nm diodes without massage or mechanical manipulation to improve the appearance of cellulite in thighs and buttocks.
Researchers treated 34 women with low-energy green light.
Subjects receives three treatments a week for 2 weeks (6).
Researchers treated subjects’ hips, thighs, a waist. Treatments lasted 30 min.
Subjects had significant:
decrease in circumference of treated areas
decrease in baseline body weight
reduction in BMI
reduction in cellulite
Low-Level Laser Therapy for Reducing the Hip, Waist, and Upper Abdomen Circumference of Individuals with Obesity
Use green light therapy to reduce hip, thigh and abdomen circumference. Subject lost an average of 15.21 cm circumference after 12 sessions of low dose green light.
Efficacy of Low-Level Laser Therapy for Body Contouring and Spot Fat Reduction
635-680 nm red light of unknown dose reduced girth at waist by 2.15 cmin men and women over 4 weeks of treatment.
Effect of 635nm Low-level Laser Therapy on Upper Arm Circumference Reduction
Use 635 nm red light to reduce upper arm circumference more than 1.5 cm.
Low-Level Laser-Assisted Liposuction: A 2004 Clinical Study of its Effectiveness for Enhancing Ease of Liposuction Procedures and Facilitating the Recovery Process for Patients Undergoing Thigh, Hip, and Stomach Contouring
Emulsify fat before liposuction extraction.
Efficacy and safety of long pulse 1064 and 2940 nm lasers in noninvasive lipolysis and skin tightening
Reduce waist circumference and total body fat, decreased fat thickness, and improve skin stiffness.
Fat Liquefaction: Effect of Low-Level Laser Energy on Adipose Tissue
Release fat from fat cell.
Reduction of Subcutaneous Fat and Improvement in Cellulite Appearance by Dual-Wavelength, Low-Level Laser Energy Combined With Vacuum and Massage
Reduce thigh fat and circumference.
Laser Acupuncture Reduces Body Fat in Obese Female Undergraduate Students
Reduce body mass index, body fat mass, waist girth, hip girth, and wast to hip ratio.
About the EMF Channel Light Dose Database
Many people purchase red light therapy or neuromuscular electrical stimulation devices without knowing optimal doses for the results they want to see. The right dose is especially key to light therapies, which have optimal windows of wavelength and energy delivered. Treatment doses outside of those windows will nullify results or harm the user. I took the results from successful EMF studies when these studies included:
- Photobiomodulation (Red Light Therapy, Blue Light Therapy, Low Level Light Therapy)
- Transcutaneous Electromagnetic Nerve Stimulation (TENS)
- Pulsed Electromagnetic Field (PEMF) Therapy
- Neuromuscular Electrical Stimulation (NMES)
Many studies do not report exact dose parameters they used. They are therefore not included here, even the study reported a therapeutic result.
