The Hot&Fresh Warming Insole Camphor – Lavender (here insert images of oils and plants) Warming: The Hot&Fresh Warming membrane takes advantage of the properties of mineral salts and essential oils, including the properties of camphor and lavender, often used in cosmetics for the production of creams and ointments, for exercise preparation and against muscle contractions. These are substances that cause peripheral vasodilation; an increase in surface blood circulation. Thanks to Hot&Fresh technology, camphor and lavender can finally be used for the production of insoles and unlike other heating products, Hot&Fresh insoles do not require direct contact with the epidermis. They also give the feet and shoes a delicate scent.

The Hot&Fresh Refreshing Insole Menthol – Eucalyptus (here insert images of oils and plants) Refreshing: The Hot&Fresh Refreshing membrane takes advantage of the properties of mineral salts and essential oils, including the properties of menthol and eucalyptus, substances long used in cosmetics for the production of lotions, creams and refreshing gels. Menthol “interacts” with the corpuscles, the cold receptors present in our skin, so as to “perceive” a temperature lower than the real one. Thanks to Hot&Fresh technology, menthol and eucalyptus can finally be used for the production of insoles and unlike other refreshing products, Hot&Fresh insoles do not require direct contact with the epidermis and do not cause any redness. They also give the feet and shoes a delicate scent.

But, technically, how does our body feel hot and cold?

The difference in temperature between the human body and the environment is primarily appreciated by the skin. Among the many receptors of this sensory organ there are the so-called “thermoreceptors”, which transmit temperature information to the central nervous system.
The Krause corpuscles transmit sensations of cold, while Ruffini’s corpuscles transmit sensations of heat.

Then, can heat and cold be considered as sensations?

Heat and cold do are sensations and, as such, are influenced by the rate of heat transfer between the body and the environment.
The sensation of heat that our body can sense at an external temperature of 20 °C (equal to 68 °F) is greater in a state of rest, rather than in a windy environment. This is due to the contact of the air with our skin.
Similarly, at an external temperature of 10 °C (equal to 50 °F), as the atmospheric humidity increases, the sensation of cold that our body can sense becomes stronger. Water moisture has, in fact, a high heat capacity.

Then, why do damp summers seem to be hotter than dry summers?

At high temperatures, the water contained by the atmospheric moisture transfer a higher quantity of heat. Furthermore, it limits the evaporation of sweat and its cooling effect on the body.

How does Hot&Fresh act on the sensations of heat and cold perceived by our body?

To reduce the sensations of heat and cold, Hot&Fresh has patented some compositions that locally stimulate skin thermoreceptors to trigger physiological responses to heat and cold. These compositions are totally natural and eco-friendly.
Contained by cooling or heating membranes, Hot&Fresh compositions can be applied to foot supports, such as orthotics and insoles, as well as to cervical collars, back wraps, belts, sweatbands, headbands and the like.
