Why are women so afraid of the cold?

Generally speaking, women are more afraid of the cold than men. Not long ago, two experts from an American institute of human health conducted a group experiment on female volunteers. The experimental report found that people with low cold tolerance have obviously insufficient iron content in their blood. The main cause of iron deficiency in women is menstruation, which leads to a large loss of iron. As we all know, iron is an important raw material for producing hemoglobin, which is the main functional substance in red blood cells and is responsible for the transportation and metabolism of oxygen in the body. Iodine and tyrosine are the main raw materials for making thyroxine. Iodine needs to be continuously ingested from food, while tyrosine is generally synthesized by itself in the body. Long-term iodine deficiency will affect the synthesis of thyroxine and reduce the body's ability to keep out the cold.
