As an item aimed at fighting against the H1N1 flu, which has recently become a global issue, an approach that focuses on flu prevention by improving hand hygiene has been adopted. This 'influenza protector' is made of flexible material, thereby ensuring convenient use. When it is worn on both arms, far-infrared rays are concentrated in one direction to measure the hand's contamination level, based on which an automatic on/off operation takes place. A person who sneezes can combine the bands on both arms into one to wear around the neck, thereby reducing the possibility of infecting others. By using far-infrared rays that are good for the human body, this influenza protector helps to remove bacteria that cause various diseases. Other effects include speeding up of metabolism, sound sleep, dehumidification, and skin care. The product can be especially useful in high influenza risk zones, such as the airport. It will be effective in preventing infection of various diseases, in addition to the H1N1 flu.
