FAQ

What is far infrared ray (FIR)?

Far Infrared Ray (FIR) is a type of electromagnetic radiation with wavelengths ranging from about 5 um-14um, situated between mid-infrared and microwave radiation on the electromagnetic spectrum.

FIR is thermal radiation, meaning it is emitted by objects at temperatures found in everyday life (e.g., human body, heaters, sunlight).Unlike near-infrared (which can feel like direct heat), FIR penetrates deeper into tissues (a few millimeters) without burning the skin.

Therapeutic Uses:

FIR saunas (promote relaxation, detoxification, and circulation).

Pain relief (used in physical therapy for muscle/joint pain).

Wound healing (some studies suggest FIR improves blood flow and tissue repair).

What is PEMF (Pulsed Electromagnetic Field)?

PEMF stands for Pulsed Electromagnetic Field, a type of therapy that uses electromagnetic fields to promote healing and reduce pain and inflammation.

PEMF devices deliver controlled electromagnetic pulses at varying frequencies and intensities, which penetrate tissues and cells.

Common Uses of PEMF Therapy:

Pain Management (arthritis, back pain, neuropathy)

Bone Healing (fractures, osteoporosis)

Sports Recovery (muscle repair, reduced soreness)

Mental Health (anxiety, depression, sleep disorders)

Chronic Conditions (fibromyalgia, Lyme disease)

What are the functions of the Energy Stones and the Crystals?

Hot energy stone therapy is beneficial in alleviating minor muscle spasms and improving flexibility. It can also work to soothe your body and mind, increasing your sleep abilities and energy levels.

Hot energy stone, such as amethyst, jade, and tourmaline, release far-infrared rays and negative ions when heated. This combination helps relax muscles, improve circulation, and ease stiffness by delivering deep, soothing heat.

The energy stones and crystals also stimulate pressure points, helping to release tension, enhance flexibility, and promote overall relaxation.

What is the function of 660nm and 850nm light?

The 660nm (red light) Penetration Depth: ~1–5 mm (superficial layers of skin and muscles)

850nm (near-infrared, NIR) light Penetration Depth: ~5–10 cm (reaches deeper tissues, muscles, joints, and bones)

Synergistic effect for superficial + deep tissue therapy.

Used in LED light therapy for pain relief, skin rejuvenation, athletic recovery, and anti-inflammatory effects.
