It's cold, my face is always red and hot.

The main causes of redness and fever in winter are: the blood circulation system is blocked, the blood vessel wall is congested, and then the face will look hot and red. Long-term wind, sun or high temperature stimulation. It will cause damage to facial muscles and lead to long-term expansion of blood vessels, so it will blush. In patients with insufficient sleep, the lack of vitamins or trace elements in the body will make the capillary wall lose elasticity. Patients are sensitive to skin and external stimuli, so they will be red and hot.

1, blushing and fever caused by temperature difference stimulation in winter

In the cold winter, when you go in and out of the room and switch the temperature at will, the facial skin is stimulated several times as much as usual. Coupled with cold air stimulation, dryness, high temperature, sandstorm climate, sun exposure and other stimuli, it will cause skin hypoxia, the number of red blood cells on the face will increase, and red blood will inevitably appear.

2, excessive beauty in winter leads to blushing and fever.

Many products in beauty salons contain fruit acid, which has a strong exfoliating effect, thus achieving the beauty effect. When the cuticle on the face becomes thinner, it is easy to have red blood.

3. Frequent exfoliation in winter leads to blushing and fever.

Too frequent exfoliation will lead to thinning of the skin on the face, which will lead to red blood on the face. It is best to exfoliate once every half month and choose mild and non-irritating products.

Eating too much spicy food in winter leads to blushing and fever.

Spicy food is easy to stimulate facial telangiectasia, and red blood will appear on the face. Be sure to control your mouth.

5. Improper cleansing methods in winter lead to blushing and fever.

Using strong alkaline or strong acidic facial cleanser, the water temperature is too high or too low, and the force is too strong, which is easy to produce red blood.

6. At extremely cold temperatures, blood vessels dilate abnormally, leading to blushing and fever.

Generally speaking, heat will dilate skin blood vessels, leading to facial flushing. Although cold makes blood vessels contract, when the temperature rises, blood vessels will rebound and expand, causing blushing. But some people, at extremely cold temperatures, will also blush because of abnormal blood vessel expansion. The clinical manifestations are filiform, punctate, star-shaped or flaky erythema on the face.

7. Blushing caused by too large temperature difference in winter.

When the temperature difference is too large, for example, from the cold wind blowing to the air-conditioned room, it is hot and cold, and the capillaries lose their elasticity in repeated contraction and expansion, which is reflected on the cheeks and nose, which will make the cheeks red and sting. At the beginning, the face can be restored to its original state immediately when it turns red, but if it continues repeatedly for a long time, the blood vessels contract, lose their expansion function, and harden in the state of overstretching, making the face look very red at ordinary times. In severe cases, facial flushing's symptoms will also appear after lowering the head and raising the head. This symptom is relatively calm in spring, summer and autumn, and becomes more serious in winter.

Precautions for fever in facial flushing in winter

In winter, we should avoid the cold environment and the sharp change of temperature, and pay attention to the moisturizing and warm work of the skin. In a particularly dry and hot room, if your face feels dry, you should replenish water in time and wash it with warm water. Scarves or masks can be used outside to prevent cold air from directly attacking the face, avoid excessive humidity difference and temperature difference, and make the dilated capillaries contract rapidly when they are cold, forming red blood. People with a history of facial frostbite should always wipe their faces in winter to promote blood circulation.
