Flushing is a sensation of warmth and redness that usually affects the face, neck and chest. Flushing can occur for various reasons, such as emotions, temperature, food, alcohol, medications or medical conditions. Flushing is usually harmless and temporary, but it can sometimes be a sign of a more serious problem. In this blog post, we will discuss the causes, symptoms and treatment of flushing, as well as some tips on how to prevent and cope with it.
What causes flushing?
Flushing is caused by the dilation of the blood vessels under the skin, which increases blood flow and heat to the affected area. Flushing can be triggered by different factors, such as:
• Emotions: Flushing can occur when you feel strong emotions such as embarrassment, anger, anxiety or excitement. This is because emotions can activate the nervous system, which releases hormones that affect blood pressure and blood vessel dilation. Flushing due to emotions is also called blushing and it usually affects the face and neck.
• Temperature: Flushing can occur when you are exposed to heat or high humidity. This is because your body sweats to cool itself down and dilates the blood vessels to release heat. Flushing due to temperature is also called thermoregulatory flushing and it can affect any part of the body.
• Food: Flushing can occur when you eat certain foods that are hot, spicy or contain chemicals that affect blood vessels. Some of the common foods that can cause flushing are chili peppers, curry, garlic, cheese and chocolate. Flushing due to food is also called gustatory flushing and it usually affects the face and chest.
• Alcohol: Flushing can occur when you drink alcohol or have alcohol intolerance. This is because alcohol can affect the way your body metabolizes a substance called acetaldehyde, which causes blood vessel dilation and inflammation. Flushing due to alcohol is also called alcohol flush reaction and it usually affects the face, neck and chest.
• Medications: Flushing can occur when you take certain medications that have flushing as a side effect or interact with your body’s temperature regulation. Some of the common medications that can cause flushing are antibiotics, antihistamines, anticonvulsants, immunosuppressants, chemotherapy drugs and nonsteroidal anti-inflammatory drugs (NSAIDs).
• Medical conditions: Flushing can occur when you have certain medical conditions that affect your hormones, blood pressure or blood vessels. Some of the common conditions that can cause flushing are menopause, hyperthyroidism, infections, fever, cancer, acromegaly, lymphoma, leukemia or malaria.
