The skin on your face turns red when it gets hot

It is a normal physiological phenomenon that the skin on your face turns red when it gets hot. This is mainly because the skin is relatively thin. When the skin gets hot, it causes the capillaries to expand, causing the skin to appear red. For this symptom, we can pay more attention to skin care in daily life. We should hydrate and moisturize our face more often, so as to avoid the symptoms of thinning skin. You can learn about the specific causes of the disease below.

What are the reasons for blushing when exposed to heat?

1. The facial stratum corneum is too thin

Some people are born with a very thin facial stratum corneum, so it is easy to see the capillaries on their faces and the red bloodshot on their faces are more obvious. When this type of people are exposed to heat, the capillaries on their faces expand rapidly. Their pores are small and it is not easy to dissipate heat. Their blood vessels are less elastic, which can easily cause the skin's stratum corneum to become allergic, leading to blushing.

There is another type of people who do not take good care of their face, which often causes their face to be dehydrated, with obvious dryness and flaking. However, every time a layer of skin is peeled off on the face, the stratum corneum becomes thinner, and the facial skin is prone to allergic blushing when encountering external stimuli. For this type of people, they should apply an appropriate amount of hydrating and moisturizing skin care products on their face to repair the skin's moisture-locking layer, and do not use any exfoliating products to damage the skin.

2. Better peripheral blood circulation

Some people have better blood circulation in the facial extremities, and they will blush when they move a little. When the face is exposed to heat, the capillaries continue to expand and peripheral blood circulation speeds up, which can be clearly seen as blushing. This type of people should strengthen physical exercise to enhance the skin's resistance and relieve the condition of frequent skin redness.

3. Excessive temperature difference

According to the principle of thermal expansion and contraction in physics, heat will cause the blood vessels in the human skin to dilate, while cold will cause the blood vessels in the skin to contract. When you're outdoors in the winter, your blood vessels quickly contract when they encounter cold air. Once you get indoors and the temperature rises, your blood vessels slowly begin to expand, causing the blushing phenomenon we see. However, frequently moving back and forth between extremely cold and hot places will cause the capillaries in the skin to lose their original elasticity due to repeated contraction and expansion. Generally, in the early stages, facial flushing can recover immediately; once the capillaries are repeatedly dilated for a long time, they will lose their elasticity and may even be unable to recover, causing the face to remain red and develop patchy redness.

In winter, you should keep your face warm to prevent your skin from losing elasticity due to sudden temperature changes. Hydrate your face in a dry room and try to wash your face with warm water to avoid irritation from cold water. In the summer, you should do a good job of sun protection on your face to avoid direct exposure to sunlight on your face, which would damage your skin and cause redness on your face.

After seeing the above three reasons for blushing when exposed to heat, I believe you can identify which type you belong to.

So what other reasons can cause capillaries to dilate and aggravate facial flushing when exposed to heat?

1. Drink less coffee, tea and other caffeinated beverages

The caffeine contained in beverages such as coffee has a stimulating effect on human blood vessels. If people with sensitive skin drink them frequently, it will cause the capillaries to dilate and lose elasticity. When exposed to heat, the capillaries on the face lose their previous elasticity, which is not conducive to heat dissipation and blood circulation, resulting in facial flushing.

2. Eat less alcohol, chili peppers and other spicy foods

Spicy foods can also aggravate the dilation of capillaries and cause redness on the face. Long-term consumption will cause the capillaries to lose elasticity, causing the face to become redder when exposed to heat.

Since the skin is already very dry and dehydrated in spring, and the characteristics of spring make the skin even drier, Meimei recommends using skin care products with good hydrating and soothing effects. It does not contain any ingredients that may irritate sensitive skin and can hydrate and soothe the skin. The deep repair ability can also relieve skin redness, nourish the skin well, relieve dry and dehydrated skin in spring, and repair the damaged skin barrier to relieve red blood streaks.
