What causes women to suddenly become afraid of the cold?

Many people say that women are made of water. Yes, compared with men, women have more water in their bodies and more fat than men. So why are women afraid of cold?

Women’s skin is more sensitive

The "sensors" in women's skin are more sensitive than those in men's, and they transmit the "cold" information to the brain more quickly. After the brain receives the information, the metabolic system immediately speeds up its work, and the blood circulation system retreats from the skin and limbs to the torso. When the temperature drops to an unbearable level, the human body will instinctively overreact, the metabolic process will be faster, and the blood circulation will retreat faster.

Women have less muscle and more fat

Compared with men, women have less muscle and more fat. In the process of oxidizing carbohydrates and fat, muscles need to consume a large amount of calories and emit a large amount of heat energy. So men have a fast metabolism and women have a slow metabolism. Men consume more calories than women, and they have more muscles in their bodies, so their metabolism is faster than women. However, their blood circulation system retreats much more slowly than women, so women are more afraid of the cold.

Women with iron deficiency are more sensitive to cold

People with low tolerance to cold have insufficient iron in their blood, often accompanied by low plasma thyroid hormone levels. Women lose a lot of iron mainly due to menstruation. Iron is an important element for the production of hemoglobin. Hemoglobin is responsible for the body's oxygen transport and metabolism. If sufficient iron is not supplemented, women are prone to iron deficiency anemia, nutrients cannot be fully oxidized, heat production is insufficient, and they are more likely to feel chills.

Women's body temperature is affected by estrogen levels

When a woman's menstruation begins, her estrogen level rises, her blood vessels dilate, and blood flows to the skin extremities throughout the body, causing the body to feel warmer. On the contrary, when the estrogen level drops, blood vessels contract and blood will flow back to the trunk. In addition, the estrogen content in women is higher than that in men, and the heat in the body is easily converted into fat and stored under the skin. The metabolic rate is lower than that of men, and the synthesis of heat is greater than the decomposition of heat, resulting in less heat released from the body.

Insufficient thyroid hormone secretion

Thyroid hormone has a heat-generating effect, which can increase the body's basal metabolism, speed up blood circulation in the skin, and increase heat. When thyroid hormone secretion is insufficient, it can reduce blood circulation in the body, thereby reducing the body's ability to generate heat, resulting in cold hands and feet in winter and even becoming very afraid of the cold.
