Why does the hair dryer feel cold after taking a shower?

When people take a bath, the skin temperature will drop due to the alternation of hot and cold water. In order to maintain the body temperature, the body will constantly lose heat, so that the heat inside the body will be radiated through the surface layer of the skin, resulting in heat loss. When we walk out of the bathroom, the body heat loss continues, and the skin surface is still in a state of heat dissipation. If we use a fan or a hair dryer to blow air immediately, we will easily feel cold in this state.

2. Moisture has an evaporative cooling effect on the skin surface

When a person takes a bath, water will remain on his body and hair, which will evaporate immediately when he encounters air. Heat will also be lost in the process of evaporation of water, which will lead to the drop of body temperature, thus making people feel cold. Coupled with the relatively high wind speed of the blower, the evaporation speed will be faster, thus aggravating this cooling effect.

3, the body's sensitivity to temperature changes increases

When taking a bath, the water temperature and air temperature are in a relatively warm environment, and the human body will adapt to this warm state at this time. However, when we blow dry our bodies with cold air, the ambient temperature will suddenly drop, and the human body has no time to adapt to this change, which leads to an increase in the sensitivity of the body to temperature, thus feeling colder.

4, physical fatigue and decreased immunity lead to colds

Too long blowing time after bathing will lead to increased physical fatigue and decreased immunity, which will easily lead to colds and other diseases. In addition, you should avoid using cold air to dry your hair or body after bathing, otherwise it will easily cause adverse reactions such as headache and muscle spasm.
