The Amethyst Far Infrared Heating Pad (18" x 18") combines:

• Far Infrared (FIR) heat
• Heated natural gemstones (Amethyst, Tourmaline, and Obsidian)
• Natural Negative Ions and grounding support from the stones

This pad does not contain PEMF or Photon (red) lights—it’s focused on deep, even FIR warmth and grounding in a compact format.

This pad is designed as a localized solution for smaller areas of the body. It:

• Targets specific zones like the abdomen, lower back, hips, knees, or shoulders
• Uses a rich gemstone blend to evenly distribute heat across a smaller surface
• Is lightweight, portable, and easy to use on a sofa, chair, or bed
• Offers a more budget-friendly entry point into Far Infrared gemstone therapy compared with full-size mats

If you’re looking for something small, simple, and powerful for focused relief, the 18" x 18" is a strong choice.

Use this pad anywhere you’d like targeted warmth and relaxation, such as:

• Lower back or abdomen
• Hips and glutes
• Knees, calves, or feet
• Shoulders or upper back (while seated or lying down)

You can place it on a chair, sofa, or bed and rest the desired area directly over the pad. Adjust the temperature to a comfortable level and start with shorter sessions, especially if you’re new to Far Infrared heat.

This pad uses a single active therapy—Far Infrared heat generated by the gemstones. You can:

• Adjust temperature and session length with the controller
• Lie on the pad with heat off if you want a gentle grounding experience from the gemstones alone

Negative ions and grounding are naturally produced by the stones, especially when heated, so they’re not controlled separately by the controller.

Amethyst 1818 is designed for regular use, and many people build them into a daily routine. A good starting protocol is:

Week 1:

• 3–4 sessions per week
• 20 minutes per session on low–medium heat with gentle PEMF settings
• Drink a full glass of water before and after your session

Week 2 and beyond:

• Work up to daily use if it feels comfortable
• 20–40 minutes per session
• You can split this into a shorter morning focus/activation session and a longer evening wind-down session

For best results:

• Allow about 20–25 minutes for the mat to fully heat up before your main session.
• Use the included cover or a thin blanket if you prefer a softer surface—it won’t affect performance.
• Take a moment after each session to notice how your body feels and adjust time and temperature.

Everyone’s comfort level is different, so listen to your body and increase gradually rather than pushing for long or intense sessions right away.

You can fall asleep while using the pad, but we recommend:

• Keeping heat at a low setting if using it near bedtime
• Positioning it under the specific area you want to support, rather than your whole body
• Using the automatic shut-off timer so the pad turns off after a set period

Because it’s a smaller pad with gemstones, some users find it firmer than a typical cushion. If you’re sensitive to firmness, use it for pre-sleep relaxation and remove it before sleeping through the night.

HealthyLine products are designed with safety in mind and include:

• Adjustable temperature controls
• An automatic shut-off timer
• High-quality, heat-resistant materials

As with any heat-based device, consult your healthcare professional before use if you are pregnant, have reduced heat sensitivity, or have specific medical conditions. Always follow the user guide and begin with lower temperatures, increasing gradually as you get comfortable.

Yes, pets can benefit from these therapies, but start with lower settings and monitor their response. Always set the temperature below 104°F and make sure your pet can freely move off the mat or chair at any time.

No. The Amethyst Far Infrared Heating Pad does not contain PEMF or Photon lights. It focuses on Far Infrared heat, gemstones, Negative Ions, and grounding. If you’re looking for PEMF and Red Light therapy in addition to FIR, consider series like TAJ, Jet, Platinum, or Rainbow Chakra.

To clean your pad:

1. Turn it off and unplug it
2. Allow it to cool completely
3. Use a soft cloth lightly dampened with water to gently wipe the surface

This is the only recommended cleaning method. Do not use soap, alcohol, disinfectant wipes, sprays, solvents, or harsh cleaners, and never soak, spray, or submerge the pad in water. Let it dry completely before plugging it back in or using it again. Using a thin towel or cover on top can help keep the surface clean.
