DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) This invention relates to a health information display device that notifies current environmental information and health information based on temperature and humidity.

(Prior Art) It is well known that a person's health condition is generally affected by the temperature and humidity of the air.

For example, during the hot and humid summer months, you sweat a lot, which is uncomfortable, and if you exhaust your physical strength, you may catch the so-called summer cold due to the azone virus, which tends to breed in hot and humid conditions. In addition, in the low temperature and low humidity conditions of winter, the movement of the human nasal mucosa becomes weak, and influenza, which prefers low temperature and dry conditions, becomes prevalent.

In view of this point, the Japan Meteorological Agency and other organizations have traditionally disseminated dry weather advisories, discomfort indexes, information regarding influenza, etc. through the mass media.

(Problem to be solved by the invention) In the case of the above-mentioned conventional technology, the above-mentioned information is only provided based on the general outside temperature and humidity, and it is not something that can be specifically recognized in individual households. . Moreover, in a typical household, one usually only knows the temperature using a thermometer, but there is no way to specifically know the current humidity of the room or what the environmental condition is; it is simply a person's intuition. I could only rely on.

This invention was made in view of the above-mentioned problems, and it is possible to display information on specific human health conditions based on current temperature and humidity, so that health information can be easily and accurately recognized at each location. The purpose of the present invention is to provide a health information display device that provides improved health information.
