Application notes
Do not delete!
The heat development of our thermopads depends on the following components: Ambient temperature, oxygen, insulation and dry environment. The reaction can therefore vary slightly for each warmer.
The respective instructions for use must be observed. For example, most thermal pads require an insulating layer (e.g. shoes, clothing, gloves, etc.). This is the only way to control the circulating air and thus the heat development.
Or to put it another way, even the best heating system in an apartment is useless if the windows are wide open.
The warmers only contain non-toxic substances and must be disposed of with the residual waste. The foil packaging must be disposed of in the yellow bag. All Thermopad packaging has the Green Dot.
Depending on the type of warmer and storage conditions, warmers generally have a shelf life of several years. In individual cases, please check the expiration date printed on the package. However, the warmer can only be used once.
After the expiration date, the typical properties of an activated charcoal warmer decrease. The maximum temperature will increase and the specified heating time will be undercut. Please bear this in mind if you use the warmer after the expiration date.
Maximum temperature: Highest value from ten random samples during the entire heating period. The maximum value is not exceeded, but can also be 30% lower in individual cases.
Durchschnittstemperatur: Die Durchschnittstemperatur von zehn Stichproben während der Wärmedauer, d.h. während der der Wärmer einen für jeden Wärmertyp definierten Temperaturbereich überschreitet, liegt bei +/- 10% vom angegebenen Wert.
Heat duration: Average duration for eight samples during which the warmer exceeds a temperature range defined for each warmer type. This is usually higher than the specified value, i.e. the actual heating time is likely to be longer than specified, in contrast to non-Japanese products.

The heat generated by the thermopads should be transported and distributed throughout the body by the blood circulation. However, this process can be disrupted if the warmer is pressed firmly against the skin, slowing down blood circulation. This can also happen while sleeping. In this case, the heat cannot be distributed evenly and becomes concentrated on a small area of skin, which heats up disproportionately. This can result in minor burns. This condition is known as a “low-temperature burn.” If this occurs due to improper use, cool the affected area and consult a doctor.
Under normal circumstances, it is impossible for a fire to start. However, as soon as a number of factors outside the normal use of a Thermopad warmer come together (highly concentrated oxygen in combination with a large number of open Thermopads), a fire can start.
The ingredients of the warmers are non-toxic. However, there is a risk of swallowing or inhaling the ingredients. Furthermore, children may not be able to assess the heat development correctly. For these reasons, the warmers are unsuitable for children under the age of 6.
The ingredients of the warmers are non-toxic. However, there is a risk of “swallowing” or inhaling the ingredients. In this case, consult a doctor as soon as possible.
All heating pads generate heat, and if used excessively, they may feel too hot. To avoid burns, remove the heating pads immediately if they become too hot. People with sensory impairments (e.g., diabetics, patients with peripheral arterial disease, people with paralysis, etc.) may not be able to feel the heat and therefore cannot tell if the temperature is too high.
Heat pads generate heat at different maximum temperatures, and some of them also have an adhesive backing.
The combination of these characteristics dictates the appropriate use of each individual warmer.
If used improperly, these warmers may cause minor skin burns; therefore, they should only be used in accordance with the instructions for use.

The roots of activated carbon heaters go back to the years 1950-1953. At that time, it was discovered that iron heats up quickly when it oxidizes. An American soldier deployed in the cold on the Korean peninsula harnessed this chemical process by putting iron powder and salt in a container and using it as a warmer. In 1978, disposable warmers in their current form were produced for the first time. There are now over 150 different types of activated charcoal heaters in Japan for a wide variety of purposes.
When the feet cool down, the blood vessels in the nose contract. The reduced blood flow restricts the immune defense. Cold viruses, which are always present anyway, then have an easy time of it. That’s why we recommend our foot warmers. Available as toe warmers or sole warmers. And you’ll never have cold feet again!
It is neither due to clothing that is too airy, nor to hormonal balance, nor to a different body temperature. Above all, it is due to the average (!) fat percentage, which is around 25 % for women and only 15 % for men. Men, on the other hand, have a higher proportion of muscles and metabolically active body mass. As the tissue with the best blood supply, the muscles act as internal heating. Another reason for the increased sensation of cold in women is their thin skin. The male epidermis is around 15 % thicker than the female. However, this is not due to the effect that thicker skin provides more insulation than thinner skin. If there is a risk of heat loss, the blood flow to the skin is reduced, which works better with thin skin. This means that the temperature difference between the inside of the body and the surface of the skin is greater than in men. So please don’t take it as whining if “she” is cold again, it is anatomically and medically justifiable. And after all, you can help. As long as evolution does not compensate for these disadvantages in other ways, there are fortunately thermal pads. Incidentally, 55% of our private customers are women. At least the ones who order. We don’t know what percentage of the pads purchased are used by women. But maybe we’ll start a survey soon.
Medical warmers can be applied directly to the skin – therefore they generate a lower temperature (max. 42 °C) than our non-medical products (comfort warmers).
