People, especially East Asians, use mouth coverings and nasal masks to prevent droplet/air infections, but those with nasal obstruction sometimes feel uncomfortable to breathe with the mask. One of the reasons might be lack of heat and humidification. It has been reported that local thermotherapy, such as in the facial eyelid region and in the neck region, was useful to ameliorate mental stress and fatigue. Based on these background findings, our first attempt was to develop a new mask which can add heat and humidification, and then investigation was performed to identify whether the mask can improve nasal resistance and subjective feelings including relaxation, nasal symptoms, and so forth. Furthermore, additional evaluation was conducted to examine whether breathing pattern is modulated by our newly developed mask, with the assumption that the mask can change breathing route due to decreased nasal resistance.
The publication scheme for the epub_identifier. This is put inthe Dublin Core metadata. For published books the scheme is 'ISBN'. Ifyou use the project homepage, 'URL' seems reasonable. The default valueis 'unknown'.
The reason for breathlessness is that the body needs more oxygen than it is getting. So you breathe faster to try to increase the flow of oxygen-rich air into the lungs. From the lungs, oxygen gets into the bloodstream and is pumped round the body by the heart.
