“There are the following reasons for cold feet when blowing on air conditioners.
Blowing air conditioning easy feet cold more because of their own weakness, such as anemia, or usually eat less, excessive weight loss, the body stores less blood or fat, the ability to generate heat and maintain the normal temperature of the body is not strong; peripheral circulation blood volume is relatively small, less heat production.
When blowing into the cold air of an air conditioner, the temperature of the body’s surface drops and the body needs to produce heat and transport it to various parts of the body in order to maintain a suitable temperature.
When the blood flow to the ends of the limbs, such as the legs and feet, is insufficient, the heat is reduced, causing the feet to become cold, even below the temperature in the air-conditioned room.”
