I read in the safety instructions that I shouldn't use the Warmers while sleeping – Why not?
The heat generated by the Thermopads, should be distributed through the body by blood circulation. This process can be disturbed if a warmer is pressed firmly against the skin, impeding the circulation of blood. This can happen during sleep. If this happens, the heat cannot be distributed optimally, and is concentrated on just a small part of the skin, which is heated disproportionally strongly. This can lead to light burns known as “low temperature burns”. Should this occur through inappropriate use, cool the affected area and seek medical advice.



Can Thermopad Active Charcoal warmers cause a fire?
Under normal circumstances of use it is not possible for a warmer to cause a fire. However, if some factors outside of the normal expected use of a Thermopad warmer are combined, (a high concentration of oxygen together with a large amount of opened Thermopads) then it is possible that a fire could occur.



My Thermopads don’t get warm. What can I do?
The heat development depends on the following components: temperature, oxygen, isolation and dry environment.
Therefore the chemical reaction of the warmers can vary.
Further information



I think my child / my pet has swallowed some of the contents of a warmer – what should I do?
The contents of the warmers are non-poisonous. However, there is always the risk that a child or a pet could choke on the packaging.
If you think your baby or small child may have swallowed the contents of a warmer, seek medical advice immediately.
If you think your pet may have swallowed the contents of a warmer, seek veterinary advice.



How long can I keep the Warmers?
Depending on the type of warmer and storage, the warmers can be kept for between one and several years. Please check each individual packet for the printed use-by date information.



Can I still use Thermopad Active Charcoal warmers after the Use-by date?
After the specified use-by date, the typical properties of the Active charcoal warmers decline. The maximum temperature will increase, and the heating duration will decrease. Please be aware of this if the warmer is used after the Use-by date.



How do I dispose of Thermopad Active Charcoal warmers?
The contents of the warmer are non-poisonous, and can be disposed of in the normal general waste bins.



History of the warmers
The Japanese Association for Active charcoal warmers places the roots of the current Active charcoal warmers back in the years between 1950-1953. It was discovered at that time that Iron heats quickly when it is oxidised. An American soldier, stationed in the Korean peninsular, found a way to exploit this process by filling a container with iron powder and salt, and using it as a warmer. In 1978 the first disposable warmers in the form used today were produced. In Japan there are now over 150 different types of active charcoal warmers available for the most diverse applications.



Why do women get colder than men?
It doesn't depend on too loose clothing, nor does it depend on hormone balance, or even on different body temperature. Above all, it depends on the average (!) Body Fat percentage, which is around 25% for females, and around 15% for males. Men have a higher percentage of muscles - metabolically active bodymass. The muscles, receiving the most blood circulation, serve as an internal heating system. Another reason for the increased sensitivity to the cold in women could be thinner skin. The male epidermis is around 15% thicker than that of the female. However it doesn't work as you might imagine, with thicker skin providing more insulation against the cold than a thinner skin. With a threatened loss of body heat, the circulation to the skin is reduced, which works more effectively with thinner skin. In this way the temperature difference between the skin surface and inside the body is much higher in women than in men. So, the next time 'she' is cold, don't think that she is just moaning. It is anatomically and medically justifiable. And finally, we can always help. As long as evolution doesn't compensate for this problem in another way, then happily, we have Thermopads. Incidentally, 55% of our private customers are female, at least those making the orders. What percentage of these warmers are used by women we don't know. But perhaps we'll do a survey soon...




What do the different temperature and heat duration figures mean?
Maximum temperature: The highest value from ten samples taken during the total duration of heating. The Highest value will not be exceeded, but can in isolated cases be 30% lower
Average Temperature: The average temperature of ten samples taken during the duration of heating, during which the warmer exceeded a temperature defined for each warmer type. Can vary +/- 10% from stated value. Heat duration: Average duration from eight samples, during which the warmer exceeded a temperature defined for each warmer type. Usually this is above the stated value.
