Why does sensitive skin get hot? How to quickly solve the problem of sensitive skin getting hot?

Sensitive skin will turn red, hot, and even have red blood streaks when exposed to cold or heat. Why does this phenomenon occur? What causes sensitive skin to get hot? Also, how to quickly solve the problem of hot face with sensitive skin?

Why does sensitive skin get hot?

Because the sebum membrane and stratum corneum of sensitive skin are damaged, the skin's resistance and defense are weakened, so the capillaries are very easily dilated by external stimuli. The temperature of the skin changes with the external temperature, and the blood flow rate in the skin also changes. Therefore, when the outside temperature rises, the body's temperature will also rise, and blood circulation will accelerate. In order to balance the temperature, the skin will automatically begin to dissipate heat. As a result, the skin will turn red and hot when it encounters heat. This is the skin dissipating heat.

Analysis of the specific reasons for redness and hotness of sensitive skin

1. We need to start with the heat dissipation pathway of the skin. Skin temperature plays a dominant role in regulating heat dissipation, and the level of skin temperature is determined by the amount of blood flow in the skin. The skin microcirculation has a rich capillary network, venous plexus and a large number of arteriovenous anastomoses, which allow the skin blood flow to vary within a wide range. The skin and subcutaneous tissue have low thermal conductivity and act as a thermal insulation layer. The contraction and relaxation of skin blood vessels is mainly due to reflex activity caused by changes in environmental temperature, which stimulate the skin's temperature receptors.

2. The body temperature regulation mechanism controls the caliber of blood vessels through the sympathetic nerves. For example, in a cold environment, the sympathetic nerve tension increases, the skin blood vessels constrict, the blood flow decreases, the skin temperature drops, and the heat dissipation decreases. When the skin blood vessels constrict to the highest degree, there is almost no blood in the skin. In a warm environment, the opposite change occurs and the heat dissipation increases. That is to say, the temperature of the skin changes with the external temperature, and the blood flow rate in the skin will also change. When the outside temperature rises, the body's temperature will also rise, and blood circulation will accelerate. In order to balance the temperature, the skin will automatically begin to dissipate heat. As a result, the skin will become red and hot when exposed to heat. It turns out that the skin is dissipating heat. When you are exposed to cold, the lower external temperature stimulates the blood vessels, causing them to rupture and become unable to contract. Therefore, when the face is exposed to cold, it will also turn red but not hot.

3. Generally speaking, capillaries are invisible to the human eye, so when they are unobstructed, what we don’t see is just facial flushing, or in layman’s terms, a red face. Moreover, this situation will only occur in people with skin and physique that are sensitive to external temperature. Therefore, children's faces will become noticeably red when they exercise or walk outside in winter. As they grow older, the redness will gradually disappear as their immunity increases. Although healthy skin will also turn red, the area is smaller and it will quickly disappear on its own. People with sensitive skin are special. In addition to genetically sensitive skin, blushing of sensitive skin is due to improper skin care that damages the sebum membrane and stratum corneum, causing the skin's resistance and defense to be weakened, so the capillaries are easily dilated by external stimuli.

How to quickly solve the problem of hot sensitive face

1. Cold compress to quickly cool down

Many people's faces become red and hot when they come back from going out. This may be caused by your skin being allergic to ultraviolet rays. At this time, you only need to prepare a basin of cold water, a towel and a few ice cubes, soak the towel in cold water, wring it dry, and then put the ice cubes in the towel. Apply cold compresses to the hot and burning areas on your face for about 20 minutes and the facial symptoms will be alleviated. If not, it is recommended to repeat cold compresses until relief is achieved. Therefore, people with sensitive skin should take good sun protection measures when going out.

2. Use skin care products to solve the root cause

The hotness and redness on the face are caused by the damage and thinning of the stratum corneum, which damages the barrier muscle. Therefore, repairing the skin barrier is the ultimate and effective way to solve the problems of red blood streaks, redness and hotness of sensitive skin. At this time, you can use some repairing skin care products, which can effectively relieve the symptoms of redness and hotness. Professional sensitive skin repair products can repair the damaged skin barrier, rebuild the skin's normal growth environment, help the skin lock in moisture, start from the root cause, and effectively repair sensitive skin problems.

3. Eat more fruits and vegetables to regulate your body from the inside

Fruits and vegetables are natural skin care products. Regular consumption of seasonal fruits and vegetables can replenish the vitamins missing in the skin. Lack of vitamins will reduce the skin's resistance, causing redness and hotness in hot and cold environments. Timely supplementation of natural vitamins can enhance the skin's ability to resist oxidation and improve skin quality problems, thus alleviating the symptoms of redness and hotness on the face.
