Therm-ic has a long history, which began with the invention of heating systems for ski boots. Building on the developments and patented technologies of the last 20 years, our range of products now includes a variety of high-quality solutions in the field of portable heating systems, which are proven to provide warmth.
We became cold experts, and our know-how was requested more and more often. Our team started talking to people around the world, convincing brands, companies and end-consumers that there was a real solution to cold in the extremities.
It is important…
to take care of our hands and feet in all circumstances. When the body’s endogenous insulation is insufficient, external insulation is necessary for a balanced body temperature and well-being. The aim is to keep your body in the ideal comfort zone, eg. A temperature of 37° C.
Our body operates at 37° C as long as the blood flow functions at a normal rate. The flow rate depends on temperature and pressure. It is highest in the body core (40cm/sec) and up to 1/1000 times lower (0,4mm/sec) when it finally reaches the most distant extremities (fingers, toes) and before it pushes back to the core. The blood has now reached its lowest speed, is the coldest and uses additional energy to keep flowing. This process can result in cold pain or even hypothermia (undercooling). At an outside temperature below 0° C, the hands and feet can reach levels as low as 28° C.
Muscle Power and Endurance Comparison
Up to 75% of our muscle power falls victim to the cold. When cold pain is reported to the brain, over 90% of the available energy is sent to warm the affected muscles. This results in reduced muscle power and endurance as well as shivering.
Hand Challenge Comparison
The skin is a complex organ with 93% cold sensors and 7% warm sensors. The sensitive
structure consists of two mutually dependent layers, the outer epidermis and internal dermis, which rest on a thin brown fat layer serving as insulation. The functionality of the hand is ensured when the blood circulation works at a normal rate. At the hands and feet, and especially in the case of women, the skin surface is disproportionally larger compared to the overall volume and the thickness of fat insulation, causing an exceptional sensitivity to cold and deceleration of the blood circulation.
