How long should I lie on Ereada® mat and at what temperature level?

There is general guidance in our user guide, but the time and temperature are for you to choose. 

People use amethyst heating mats from one hour at high temperature to 12 hours at warm temperature daily for pleasure. You can try and see what kind of sessions gives you the most benefits.

We always recommend starting with the lowest or medium temperature levels 1-3 or 30-45°C for short periods of 20 - 30 minutes to see how your body reacts and then gradually increase the temperature and the length of the session over time. 

Of course, if you are an experienced FIR sauna user, you can start with the maximum temperature level or even use two mats (sandwiched procedures). Still, we always recommend checking with your doctor first.
