My face gets hot and red when it gets hot

Our face is not only the first impression we make on others, but also a reflection of our physical signs. For example, if we have acne on our face, it may be because our body is getting hot, or for many girls it may be because of endocrine disorders. Some people's faces may be oily, which is most likely due to problems with an organ in the body. Some people's faces will get hot and red when it's hot. Why is that?

The skin on the human face is thin and rich in blood vessels. When you are excited or shy, the blood vessels dilate and you blush, which then disappears. This is a normal physiological phenomenon. However, if for some reason the skin reacts particularly strongly to physical and chemical factors such as sunlight, cold and heat, and certain cosmetics, and tolerance is reduced, or even skin damage is caused, this is an allergy. This type of disease is related to genetics, metabolic abnormalities, general condition, light exposure, age, gender, etc.

In medicine, this condition is called "facial flushing."

From a medical point of view, blush refers to the condition in which the face turns redder more easily and lasts longer than other people due to changes in temperature or emotion, and the color is darker and lasts longer. There are blood vessels in the skin, which expand or contract due to nerve factors. Especially the cheeks are rich in capillaries, so the cheeks are more likely to turn red.

When the temperature difference is too great, such as when you go from a cold room to an air-conditioned room, and the temperature fluctuates between hot and cold, the capillaries lose their elasticity due to repeated contraction and expansion, which is reflected in the cheeks and nose, causing the cheeks to become red and stinging. In the early stages, the face will turn red and return to its original state immediately, but if it continues for a long time, the blood vessels will contract, lose their dilation function, and harden in an over-dilated state, making the face look red even at normal times. In severe cases, facial flushing may occur after lowering the head and then raising it again. This symptom is relatively mild in spring, summer and autumn, but becomes more severe in winter.

Doctors recommend that in winter, you should avoid excessively cold environments and sudden temperature changes, and pay attention to moisturizing and keeping your skin warm. In extremely dry and hot indoor environments, if your face feels dry, you should replenish water in time and use warm water mainly for washing your face. When you go outdoors, you can use a scarf or mask to prevent cold air from directly attacking your face, and avoid large differences in humidity and temperature, which will cause the dilated capillaries to contract rapidly when exposed to cold, forming red blood vessels. People with a history of facial frostbite should rub their faces frequently in winter to promote blood circulation.

In terms of diet, doctors say that people who blush easily should eat less foods that increase vasodilation, such as coffee, tea, cola and other caffeinated foods. Supplementing with some vitamin B1 can also help nerve repair and have a calming effect. In addition, you should avoid sun exposure, alcohol, spicy and irritating food, and avoid anger, tension or excessive excitement, as these will contribute to facial blushing. La Roche-Posay has a soothing spray that is quite effective for this symptom. You can try it.
