ホット パック 効果。 玄米カイロ・ホットパックで体を温める事の効果8つ|手作りの作り方は?

In silica gel that contains water, convection of water molecules is prevented by semi-solidification in a gel state. The high specific heat gives the gel a large heat capacity, and the absence of convection makes it possible to convey the thermal energy to the body slowly. The results also confirmed that thermal stimulus by hotpack therapy is effective in parts at some distance from the treated area. The results revealed that the skin temperature reached its maximum 18min after starting the therapy, maintained the same temperature for 9min, and then gradually decreased after the completion of therapy. The silica gel used in this method is a porous substance that has an extremely high specific heat. A study of the optimal treatment time for hotpack therapy was conducted using three indicators, namely, skin temperature, deep temperature, and blood flow under the skin, all of which are characteristics of heat transfer in hotpack therapy. Among various types of thermotherapy, hotpack therapy is often used because of its simplicity and ease of application. Deep temperature reached its maximum 26min after starting the therapy, maintained the same until 1min after the completion of therapy, and then gradually decreased. The volume of blood flow under the skin increased to its maximum 30min after starting the therapy, and although it gradually decreased, the volume after the completion of therapy was higher than that before therapy. Based on these results, a hotpack therapy time of 20-30min is considered necessary. Deep temperature was higher 30min after completion of therapy than before therapy. Skin temperature was higher 30min after the completion of therapy than before therapy. The experiment was carried out by measuring the skin temperature, deep temperature, and blood flow under the skin when hotpack therapy was given on the lower right leg for 30min, and the optimal treatment time was obtained based on the changes in these indicators. Both skin temperature and deep temperature showed some rise on the opposite side. The skin temperature and deep temperature on the opposite side from the treated area were also measured at the same time to study the changes in other areas.
