Why do capillaries bleed? You must know these factors

As we all know, there are blood vessels distributed under the skin of every part of the human body, especially the capillaries, which are too fragile. A little force may cause the capillaries to rupture, resulting in bleeding symptoms. In medicine, there is a disease called capillary bleeding. What are its causes?

Causes of capillary bleeding:

1. Climate and environmental factors. Long-term living in a relatively harsh living environment, such as thin air in the plateau, hypoxia in the skin, leads to an increase in the number of red blood cells and compensatory dilation of blood vessels. Over time, vascular contraction dysfunction causes permanent capillary dilation. Or sailors, chefs, farmers and athletes who are exposed to wind, cold and heat for a long time.

2. Physical factors, such as temperature changes, can cause the tolerance of capillaries to exceed the normal range, leading to capillary dilation and rupture. Excessive sun exposure can cause chronic photodermatitis and dry skin.

3. Abuse of cosmetics or long-term "monthly skin care" and improper skin resurfacing can cause sequelae. The acidic components of skin resurfacing products destroy the protective effect of the skin's stratum corneum and the elasticity of capillaries, causing capillaries to dilate or rupture.

4. Complications of certain local or systemic diseases.
