Why does my face get hot and red when I get hot?

The skin on the human face is thin and rich in blood vessels. When someone is excited or shy, the blood vessels will expand and blush, which will disappear afterward. This is a normal physiological phenomenon. However, if for some reason the skin reacts particularly strongly to some physical and chemical factors such as sunlight, cold and heat, and certain cosmetics, reducing tolerance and even causing skin damage, this is an allergy. Such diseases are related to genetics, metabolic abnormalities, systemic conditions, exposure locations, age, gender, etc.

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

From a medical perspective, blushing refers to a person who is more likely to turn red than other people due to changes in temperature or mood, and the color is deep and lasts a long time. There are blood vessels in the skin, which expand or contract under the influence of nerve factors. Especially the cheeks are rich in capillaries, so the cheeks are more likely to be red.

When the temperature difference is too large, such as going from the cold wind to an air-conditioned room, and it is hot and cold, the capillaries lose their elasticity during repeated contraction and expansion, which is reflected in the cheeks and nose, causing the cheeks to swell. Red stinging. In the early stage, the red face can return to its original state immediately, but if it continues repeatedly for a long time, the blood vessels will constrict, lose their dilation function, and harden in an over-expanded state, making the face look red even at ordinary times. In severe cases, facial flushing may occur when you lower your head and then raise your head. This symptom is relatively calm in spring, summer and autumn, and often becomes severe in winter

Doctors recommend that you should avoid cold environments and rapid changes in temperature in winter, and pay attention to moisturizing and keeping the skin warm. During extremely dry conditions, In rooms with higher temperatures, if your face feels dry, you should replenish it in time, and wash your face with warm water. When going outdoors, you can use a scarf or mask to prevent cold air from directly attacking your face, and to avoid excessive humidity and temperature differences, which can cause the expanded capillaries to shrink rapidly when exposed to cold, forming red blood filaments. People with a history of facial frostbite should rub their face frequently in winter to promote blood circulation.

In terms of diet, doctors say that people who blush easily should eat less foods that increase blood vessel dilation, such as coffee, tea, cola and other caffeinated foods. Supplementing some vitamin B1 can also help nerve repair and calm the nerves. In addition, you should avoid sun exposure, alcohol, spicy and stimulating food, and avoid being angry, nervous or over-excited, as these will cause facial redness.
