The stimulation of receptors in the spine can influence the natural thermoregulation, scientific studies have revealed. This is why The Trick wear inserted exactly there a 3D-insulationzone, so that the body feels an overheating much earlier, at a point when the core temperature is still in an optimal range. The natural cooling process (sweating) sets in earlier, whereby the temperature increase can be provided earlier. The core temperature rises not as strong as normal, because of that the energy need for thermoregulation is lower. The Trick is available for running and biking.
