<p>An apparatus for keeping body temperature of the present invention comprises a warming body surrounding the face, mouth, nose, ears, and neck of a human body; and a respiratory outer air heating device heating outer air flowed into the nose or mouth to the a certain temperature. Therefore, a body temperature increasing device is coupled with a mask to heat the respiratory outer air to be inhaled to a certain temperature, so decrease in the body temperature caused by inhalation of cold air is prevented, thereby helping prevention of cold in winter or change of seasons and release of migraine by helping smooth blood flow in the airway, and shortening time for recovering from cold.</p> |
