A dryer for controlling a drying temperature based on a body temperature of a drying target, comprising: a fan configured to blow air; a heater (H) configured to heat the blown air; an external temperature sensor (S1) configured to detect the body temperature of the drying target; an air temperature sensor (S2) configured to detect a temperature of the heated air; and a controller configured to: specify the drying target with one of a plurality of drying targets previously stored in the dryer; derive, based on information on the specified drying target, a suggested temperature (PT) and a reference temperature (ST) which is lower than the suggested temperature (PT) by a given temperature; operate a pre-warm mode when the body temperature is lower than the reference temperature (ST) and thereby to control the heater (H) so that drying is performed with the heated air of a pre-warm temperature (HT) which is higher than the body temperature and lower than the reference temperature (ST) in the pre-warm mode, the pre-warm temperature (HT) increasing as the drying proceeds in the pre-warm mode; release the pre-warm mode when the body temperature is higher than the reference temperature (ST); and when the pre-warm mode is released, perform drying with the heated air of the suggested temperature (PT). a fan configured to blow air; a heater (H) configured to heat the blown air; an external temperature sensor (S1) configured to detect the body temperature of the drying target; an air temperature sensor (S2) configured to detect a temperature of the heated air; and a controller configured to: specify the drying target with one of a plurality of drying targets previously stored in the dryer; derive, based on information on the specified drying target, a suggested temperature (PT) and a reference temperature (ST) which is lower than the suggested temperature (PT) by a given temperature; operate a pre-warm mode when the body temperature is lower than the reference temperature (ST) and thereby to control the heater (H) so that drying is performed with the heated air of a pre-warm temperature (HT) which is higher than the body temperature and lower than the reference temperature (ST) in the pre-warm mode, the pre-warm temperature (HT) increasing as the drying proceeds in the pre-warm mode; release the pre-warm mode when the body temperature is higher than the reference temperature (ST); and when the pre-warm mode is released, perform drying with the heated air of the suggested temperature (PT). specify the drying target with one of a plurality of drying targets previously stored in the dryer; derive, based on information on the specified drying target, a suggested temperature (PT) and a reference temperature (ST) which is lower than the suggested temperature (PT) by a given temperature; operate a pre-warm mode when the body temperature is lower than the reference temperature (ST) and thereby to control the heater (H) so that drying is performed with the heated air of a pre-warm temperature (HT) which is higher than the body temperature and lower than the reference temperature (ST) in the pre-warm mode, the pre-warm temperature (HT) increasing as the drying proceeds in the pre-warm mode; release the pre-warm mode when the body temperature is higher than the reference temperature (ST); and when the pre-warm mode is released, perform drying with the heated air of the suggested temperature (PT). <EOS>
