Rötung

Rötung, also known as erythema, is a common physiological response characterized by redness of the skin or mucous membranes. It occurs when the small blood vessels in the skin dilate, allowing more blood to flow to the area. This increased blood flow causes the skin to appear red. Rötung can be triggered by a variety of factors, both internal and external.

Common causes of rötung include heat, such as that experienced during exercise or exposure to a warm environment. It can also be a reaction to sunlight, leading to sunburn. Certain foods, particularly spicy ones, can induce flushing and rötung due to their effect on blood vessels. Emotional states, such as embarrassment or anger, can also cause temporary rötung. Additionally, rötung can be a symptom of underlying medical conditions.

Allergic reactions, infections, and inflammatory processes can all manifest with skin redness. Certain medications can also cause rötung as a side effect. In some cases, rötung can be persistent and indicative of chronic conditions like rosacea or lupus. While often benign and temporary, persistent or widespread rötung should be evaluated by a healthcare professional to determine the underlying cause and appropriate management. The intensity and duration of rötung can vary greatly depending on the cause and individual sensitivity.
