Benefits over time
Your PEMF journey, step by step
PEMF compounds. Real change happens on a timeline — here's what to expect from your first session through three months of daily use.
02
Week 1
Better sleep, less stress
After 5–7 sessions, alpha-theta brainwave activity strengthens. Falling asleep gets easier, you stay asleep longer, and waking-up energy noticeably improves.
03
Month 1
Inflammation calms down
Clinical studies show PEMF down-regulates inflammatory cytokines after ~4 weeks of consistent use. Stiffness, swelling, and recovery time from workouts measurably drop.
04
Month 2
Energy at the cellular level
PEMF stimulates ATP — your cells' fuel. Around the two-month mark, users report sustained energy through the afternoon and faster recovery from physical and mental fatigue.
05
Month 3
Chronic pain noticeably reduced
Three months of daily sessions consistently rank as the threshold where chronic-pain users report meaningful, durable relief — backed by the largest body of PEMF research.
660nm. The wavelength science studies most.
36 LEDs span the full-body mat, delivering even red light at 660nm — the wavelength with the largest body of research behind it.

Why 660 nanometers?
660nm sits at the peak of the visible red spectrum — the wavelength most studied for skin and cellular response. It penetrates the upper layers of the skin (3–5 mm), where it interacts with the mitochondria in your cells. 36 LEDs spaced across the mat deliver this light evenly across your entire body in a single session.
Skin renewal
At 660nm, red light is designed to stimulate fibroblast activity in the skin — supporting collagen production and a healthier-looking complexion over consistent sessions.
Cellular energy
Red light is shown to activate cytochrome c oxidase — an enzyme in the mitochondria that helps power ATP production, your cells' natural fuel.
Recovery support
Many users describe quicker post-workout recovery and reduced muscle fatigue when stacking red light with their PEMF Pain Relief preset in the same session.
Red light therapy at 660nm is one of the most extensively studied wavelengths for skin and cellular response, with hundreds of peer-reviewed papers behind it. Grooni is a wellness device, not a medical treatment — for specific health concerns, consult your clinician.

Frequently Asked Questions
We Have The Answers
What is PEMF therapy and how does it work?
PEMF (Pulsed Electromagnetic Field) therapy uses gentle electromagnetic waves to stimulate cellular activity, supporting natural recovery, reducing inflammation, and promoting overall wellness.
How long should I use the mat each day?
Most users start with 20–30 minutes per session, 1–2 times daily. You can adjust based on your goals and how your body responds.
Is PEMF therapy safe? Are there any side effects?
PEMF is non-invasive and considered safe for daily use. Most people experience no side effects. If you have a pacemaker or are pregnant, please consult your doctor before use.
What's the difference between the 5 frequency levels?
Each level (Restore, Ground, Relax, Focus, Pain Relief) corresponds to a specific brainwave frequency designed for different outcomes — sleep, balance, cognitive function, energy, and recovery.
Can I use my HSA/FSA funds to purchase?
Yes! Grooni Wellness has partnered with Truemed so you can use your pre-tax HSA/FSA funds at checkout. Save up to 30% on your purchase.
What warranty and return policy do you offer?
