Blush all over the cheek that appears after frost, it seems, should not upset us. Worse, when the nose turns red – it is ugly, but not only. The fact is that such sharp jumps in temperature are a risk factor for rosacea – a disease associated with loss of elasticity in capillaries. As a result of this, microcirculation is disturbed, the nutrition of the skin is deteriorating, the networks of blood vessels, asterisks appear on it.
Such a flow from the nose represents the protection of the body from microbes and the restoration of the normal functioning of this organ. Our nasal cavity is usually wet, covered with mucus, which collects dust and pathogenic microbes, without passing them into the body. Then all this dirt is removed by cilia, which constantly oscillate in the direction of exit from the nose. At low temperatures, the vessels in the nose narrow, the mucous membrane of the nose dries up, the movement of the cilia slows down. In the warmth, the vessels expand, a secret is produced (those same snot), which moisturizes the mucous membrane and removes “debris” from the nose – after all, in the cold, the nose cleaning system worked half-heartedly. Usually snot stops after 10-15 minutes. Continue reading
