How to start using and take maintenance of your Ereada® Amethyst or Gemstone Mat

  • Before your first session study the manual and the section about the useful tips completely.
  • Arrange your ambience. Prepare your Ereada® Amethyst Mat space to create tranquility and privacy atmosphere.
  • You can chose to cover your mat with a cotton sheet, towel or to cushion it with a special waterproof 3-D air layer protector. If you like it, and want to have better contact with crystals, you can lay on the soft suede or mesh surface.
  • It would be fine to have a blanket to cover yourself while session. Some people even use Ereada® Amethyst Mat MINI as a cover for more intensive both sides heating.
  • Have your player with relaxing music within easy reach.
  • The best is to use the Ereada® Pillow for your head.
  • Do not wear synthetic clothing on the Mat. Use only cotton or natural fiber clothes during the session. 
  • Your session should be calm and free of any disturbance. Turn off the phone signals, use the “Do Not Disturb” sign, put on an eye pillow or light protection band and your headphones, and relax.
  • Put the mat on the floor or on the bed with crystals upside. There are heat reflection layers in the mat directing heat upwards but anyhow the bottom of the mat can still heat up so better to put a towel under the mat. Cover the mat completely with a thick blanket to preheat and let it heat up for 30-60 minutes depending on the heat level chosen. If the mat stone surface is not covered entirely, you could disrupt the heat sensors.
  • You should cover your mat to catch the heat, or it will dissipate into the air. If you need to get the max temperature of 158°F (displayed as level 7 on the large mat controllers or 70°C on the mini mat controller) you should lie on the mat and use your own body to press the stones against the heating layer. Please, check for more information about the Ereada® mat heating here or in the Ereada knowledge base.
  • Use slow and continuous mode of increasing session intensity. A natural adjustment period is necessary. Begin with the low temperature levels and short time sessions of half hour or less. Increase one heat level setting at a time, until you find the setting that feels best for you. Once or twice a week sessions will be a reasonable way to start.
  • Main rule is to use the lowest temperature (level 1 or 2) settings to create a relaxing environment, for sleeping or longer time sessions. Medium temperature settings (3, 4 or 5 level) are the best for physicality and to encourage activity, some customers use them for extended time from 30 minutes to several hours. Highest temperature (levels 6-7) is for short time sessions less than 30-60 minutes deep heat and should not be used for prolonged time.
  • Try to get the cumulative effect. All humans are unique. Some people do fine on the lower settings, and get the same benefits over the long term as those who use the higher temperature settings. Ereada® Amethyst Mat provides cumulative benefits to mind and spirit on every setting. No need to hurry.*
  • The far-infrared heat deeply warms you up. It is not felt by our body in the same manner as direct heat. Only when the controller is on the high heat levels the mat may become hot to touch but usually it is felt as warm. That is why the energy is used more efficiently than in conventional heating pads warming mainly the surface layer and the ambient air. But the extra care should be taken during the learning curve to avoid overheating and unpleasant experience such as dry mouth, buzz feeling or dehydration.
  • You can gradually go up to use more powerful sessions as soon as your adaptation to the lower temperature settings is built up. Very good results are reported from incorporating ½-hour Ereada® Amethyst Mat high level sessions several times per week. For better sweating it may be beneficial to cover with several heavy natural fabric towels or blankets or to use the Ereada® Amethyst Mat Mini as a cover. You may not sweat during the first high level sessions, as you are not yet adapted. But after several procedures the healthy sweating will start.
  • Thermotolerance. For high temperature sessions with levels 6-7 after being heated, tissues develop resistance to heat, which persists for about three days and may reduce the effects of repeated heat sessions in this period. Russian and Japanese researchers suggest «cycles» up to four times a week apart.
  • Take a shower with a body scrub after every use of the Ereada® Far Infrared Amethyst Mat to remove sweat and toxins. If it is OK for you, you may finish with a slightly warm or cold water shower to close the pores.
  • Drink a lot of pure or mineral water during, before and after sessions. Proper rehydration is very important to get the Ereada® Amethyst Mat benefits and to avoid unpleasant experience such as dry mouth or buzz feeling.*
  • Do your best to arrange regularity and consistency in your sessions. Schedule the use of the Ereada® Mat into your daily routine. It is a key to get accumulated effects.*
  • Best time to use the Amethyst FIR Heating Pad or Mat for relaxation is ½-hour before bed. It will prepare your body for deepest, regenerative sleep. You can also sleep all the night on the Mat on the first or second temperature level or even with heating function off. The natural far infrared rays from Amethyst crystals will produce benefits even if the Ereada® Mat is off power. Do not use the mat on high level during the bedtime and consider using an extra plug-into socket timer set for an hour to double protect yourself in case you fall asleep.*
  • If you have a good experience of sweatingy and sports you may select higher temperature and cover your body with a blanket or the Ereada® Amethyst Mat Mini. This may increase benefits by retaining your body’s heat and may be especially effective.*
  • Please, use high heat levels with extra care. It is highly recommend to have a good training period with lower heat levels sessions experience and doctor’s approval before using the Ereada® Mat especially on the high heat levels.*
  • You can also use the Ereada® Mat when you are working, relaxing or sleeping. Regular sleeping on the mat has cumulative effect and may be extremely beneficial in promotion wellbeing. Do not forget to use the Ereada®  Mat Pillow for richer experience.*
  • In the negative ions only mode the Mats may protect you from the harmful positive ionization by electronic devices in your office.*
  • Ereada® Amethyst Mat can be used for short rest in revitalizing sessions or for a whole night sleep. Sleeping on the Amethyst Mattress may help for your practices to relieve stress and restore power. Sleeping should be done only on the lowest heat levels or in negative ions only, in no heat or non-powered mode.

The application of heat has a long history. Ancient Greeks, Romans and Egyptians used hot stones, wrapping into hot blankets or immersing into the hot water or sand.

Practitioners in ancient India used regional and whole-body hyperthermia for health purposes and anti-aging.

Asians heated by the sun the hand made mats with Amethyst, Agate, Tourmaline and Jadeite stones to accumulate the thermal healing power of the sun light which was transferred to the body while sleeping on the mat in the night.

Turkish bath, Russian banya and Finnish sauna are the other samples of traditional heat treatments that enhance wellbeing.

Thermal methods have great potential and the InfraRed Energy radiated by Amethyst crystals is the best source of such heat.*

Dr. Uwe, a famous naturopath from Germany, states in his bestseller book 98,6 F the Ideal Body Temperature as the Secret to Optimum Health that hypothermia, or low temperature, may be the cause or mark of many disorders and usually comes with age. 

The book linked above is only for informational purposes. It does not construe any medical advice or claims about Ereada® products, and like all research articles or literature, it may contain errors. The author is neither related to nor affiliated with Ereada Corp.

As per Dr. Uwe's data, hot crystals and hot stones may have great potential to support the reversal to optimal temperatures.

It is really very pleasant for almost everybody to lay on hot stones, especially in cold or chilly seasons, because of the warmth, coziness, and tranquility feeling you get from hot crystals.

All crystals, especially amethyst and tourmaline, crushed into small pieces provide an even distribution of warmth and may balance mental, physical, and spiritual wellness levels through two natural processes: negative ion emission and the release of far-infrared rays

Thanks to hot crystals, it is possible to manage comfort and wellness and naturally maintain the quality of life.

During hot seasons, the best practice may be to use the stones and crystals without heating so that they can create a comfortable environment, absorbing excessive heat and cooling you down.

It is the main way the unpowered gemstone mats are used in Asian countries.
