The invention provides a life-saving device including means for allowing the
wearer to be found easily, and a body temperature adjuster for maintaining the
body temperature of the wearer at a proper body temperature by fine-adjusting the
body temperature of the wearer depending on the outside temperature or the body
temperature until the wearer is rescued. The life-saving device includes heating
members disposed so as to contact both sides of the neck where common carotid arteries
run through and both armpits where axillary arteries run through when the main
body of the life-saving device is worn, a power source for supplying electricity
to the heating members, a body temperature detecting means for detecting the body
temperature, an outside temperature detecting means for detecting the outside temperature,
and a temperature controller for adjusting the temperature of the heating members
in response to the temperature detected by the body temperature detecting means
and the outside temperature detecting means, so that the body temperature of the
wearer can be maintained at a proper temperature in case of emergency.
