Can I use my Ereada® mat for every night sleeping?

Ereada® amethyst mats can be used for sleeping every night, and many customers use them this way.

The most important thing is to avoid overheating.

FIR hot stone mats do not work the same way as conventional heating pads or electric blankets. Most of the mat’s energy is produced in the form of Far Infrared radiant heat, especially at lower temperature levels. This heat is transferred mainly by radiation, similar to sunlight, rather than by direct conduction like the heat from a cup of hot coffee.

If you place a thick towel or blanket on a standard heating pad or electric blanket, it will block most of the heat. However, when you cover an FIR mat, you mainly reduce the conductive heat portion (about 20–40%, depending on the temperature). The infrared rays can still pass through towels, blankets, or covers.

FIR crystal mats also do not heat the surrounding air as much as standard heating pads do. Conventional heating pads often feel very hot to the touch, while an amethyst mat may feel only warm even at higher settings, although the internal temperature may be much higher. Our skin senses conductive heat immediately, but radiant infrared heat is felt more gradually.

For this reason, the mat should generally be used at lower temperature levels than traditional heating pads, especially for overnight use. Extra care is recommended when using larger mats, which are more powerful and may cause an overstimulating sensation if used at higher temperatures for long periods. For sleeping, it is best to use only the lowest heat settings.

A common routine is to have a short relaxing session before bedtime, about 30 minutes at levels 3–4 (out of 7) together with Negative Potential mode on larger mats, or about 45–50°C on Mini mats. After that, the temperature can be lowered to levels 1–2 (around 30–40°C) for sleeping.

If you feel overstimulation or a buzzing sensation, lower the temperature further or use the mat without power. This can be especially comfortable in summer, when the crystals can absorb some excess body heat.
