Red Light Therapy Basics: What Photobiomodulation Means
Photobiomodulation, or PBM, uses non-ionizing red or near-infrared light. The research spans LEDs and lasers, wavelengths roughly from 600 to 1100 nm, and highly varied doses and treatment areas. A useful reading rule is therefore simple: match the study's wavelength, irradiance, time, body area, and population before applying its result to a home device.
Red Light Basics
Understanding 660 nm and 850 nm Red Light
660 nm is visible red light; 850 nm is near-infrared and may look dim even when active. The LED component sheet used for the current rePretty Mat specifies red peaks from 650 to 665 nm and infrared peaks from 840 to 860 nm. Those component values identify the two light bands used by the current mat and help explain why the infrared channel looks dimmer to the eye.

How Long and How Often to Use a Red Light Therapy Mat
For the current rePretty Mat, begin with 10 minutes at P1 or P2, three times in the first week. If those sessions are comfortable, progress to 15 or 20 minutes, three to five times weekly. The manual caps a session at 90 minutes, which is a maximum rather than a target. Increase only one setting at a time and keep the routine comfortable enough to repeat.

Choosing a Device
How to Choose a Full-Body Red Light Therapy Mat
Choose a full-body red light mat by measuring the use surface, confirming the exact dimensions and controls, checking the finished-model measurement method, and reading the manual, care, warranty, and return path. For the current rePretty Mat, the usable facts are 72 by 33 inches, 1,436 three-channel LED packages, 660 and 850 nm bands, three modes, five levels, and a 10-to-90-minute timer.
Choosing a Device
Red Light Mat vs. Panel: Which Format Fits Your Routine?
Choose a mat when you want supported, broad, contact-based coverage and fold-away storage. Choose a panel when you prefer upright, non-contact use and can repeat the same distance and body position. Compare posture, coverage, available space, setup consistency, and how easily each format fits your routine.
Choosing a Device
How to Choose a Red Light Device Without Chasing Hype
Choose a red light device by verifying the exact model, dimensions, posture, controls, manual, warranty, and measurement method. Then check whether research claims match the same wavelength, irradiance, dose, body area, and population. A 2025 pilot measured five home devices and found inconsistent optical performance and consumer instructions, so precise-looking numbers still need a traceable method.

Everyday Routines
Building a Calmer Evening Routine Around Red Light
Use an evening red light session as a cue to reduce stimulation, not as a treatment for insomnia. Keep the room dim, silence work notifications, use a conservative 10-to-20-minute manual-based setting, and leave time to cool down before bed. Human studies show that longer-wavelength evening light can reduce melatonin suppression, but red light has not produced consistently better sleep.

Use, Care and Safety
How to Use a Full-Body Red Light Therapy Mat at Home
For the current rePretty Mat, unfold it on a dry supported surface, connect the mat, controller, and supplied adapter, then start at P1 or P2 for 10 minutes. Use it three times in the first week; if comfortable, move toward 15 to 20 minutes, three to five times weekly. Keep the controller within reach and never exceed 90 minutes.

Red Light Safety, Eye Protection, and When to Pause
Check the mat, controller, cable, and adapter before use. Keep liquids away, follow the eye-protection instructions for the exact product, and pause if the setup feels damaged, unusually hot, or uncomfortable. Use the dedicated safety guide for the full checklist.
