Overview of skin flushing

Skin flushing or blushing describes feelings of warmth and rapid reddening of your neck, upper chest, or face. Blotchiness or solid patches of redness are often visible when blushing.

Flushing happens as a result of increased blood flow. Whenever there is more blood flow to an area of skin (such as your cheeks), the blood vessels enlarge to compensate. This enlargement is what gives skin the “flushed” effect.

Flushed skin is a common physical response to anxiety, stress, embarrassment, anger, or another extreme emotional state. Facial flushing is usually more of a social worry than a medical concern.

However, flushing may be linked to an underlying medical issue, such as Cushing disease or a niacin overdose. Be sure to check with your healthcare provider if you have recurring skin flushing or blushing.

Many different conditions can cause skin flushing. Here is a list of 13 possible causes.

Cushing syndrome

  • Symptoms include weight gain, obesity, and fatty deposits, especially in the midsection, the face (giving it a round, moon shape), and between the shoulders and the upper back (causing a buffalo hump).
  • Purple stretch marks on the breasts, arms, abdomen, and thighs, and thinning skin that bruises easily and heals slowly are other symptoms.
  • Additional symptoms include acne, fatigue, muscle weakness, glucose intolerance, increased thirst, bone loss, high blood pressure, headaches, and increased risk of infection.

There are many specific causes of facial flushing, such as a heightened emotional state or eating spicy food. Several medical conditions are also linked to skin flushing. Listed below are some common causes of flushing.

Cushing syndrome

Cushing syndrome is a result of high levels of cortisol in the body.


A niacin (vitamin B-3) overdose can cause redness. This happens when you take too much over-the-counter niacin medication to lower your cholesterol. Other medications that can cause flushing include:

  • corticotropin-releasing hormone
  • doxorubicin
  • glucocorticoids
  • vasodilators (e.g., nitroglycerin)
  • calcium channel blockers
  • morphine and other opiates
  • amyl nitrite and butyl nitrite
  • cholinergic drugs (e.g., metrifonate, anthelmintic drugs)
  • bromocriptine used in Parkinson’s disease
  • thyrotropin-releasing hormone (TRH)
  • tamoxifen
  • cyproterone acetate
  • oral triamcinolone
  • cyclosporine
  • rifampin
  • sildenafil citrate

Spicy foods

Consuming spicy foods, such as peppers or products derived from the Capsicum (pepper) genus of plants, can cause sudden redness in the face or neck. These include cayenne pepper, paprika, chili peppers, and red peppers.

Eating these foods may raise your body temperature, increasing blood flow and causing facial redness. Handling these types of foods can also cause skin redness and irritation.

Emotional triggers

Extreme emotions can trigger redness in the face or red face. For example, if you become deeply embarrassed or anxious, your face or neck may appear splotchy.

Experiencing feelings of extreme anger, stress, or sadness may also cause skin flushing. Crying can often cause red blotches on the face and neck.

All of these emotions can also coincide with an acute increase in blood pressure. Still, high blood pressure itself is not a cause of flushing, according to the American Heart Association.


Rosacea is a skin condition that may produce swelling, redness, and acne-like sores.

While the cause of rosacea is unknown, inflammation of the blood vessels from stress, spicy foods, and hot temperatures may worsen the condition. Fair-skinned females between the ages of 30 and 50 are the most susceptible.

Fifth disease

Fifth disease is caused by a virus and can result in a red rash on the cheeks, arms, and legs. It’s commonly spread among elementary school-aged children and usually results in mild flu-like symptoms. A red rash from fifth disease is more likely to appear in children than adults.

Other causes

Other, less common causes of facial blushing or red face include:

There are several home health options available to help you decrease your flushing episodes.

If home health options don’t prevent or lessen the frequency of these episodes, see your healthcare provider immediately. It may mean that you have an underlying medical condition causing this sudden redness.

Home health options

Home health options include avoiding specific triggers, such as spicy foods, hot beverages, toxins, bright sunlight, and extreme cold or heat. Removing yourself from high-stress situations may also help prevent flushing.

If your flushing doesn’t subside, make an appointment with your healthcare provider.

Flushing does not commonly result in serious medical problems. However, in some instances, a serious condition can be the underlying cause of flushing. It’s important to talk to your healthcare provider about all of your symptoms.

Also, pinpointing your triggers can help prevent bouts of flushing. If your trigger is emotional, flushing can become more prevalent if you don’t develop adequate coping skills to help manage your emotions.

There is no definitive method for preventing flushing. However, there are some things you can do to reduce the risk of these episodes:

  • Limit the amount of alcohol you drink. Some people are more prone to redness and warmth on the skin after drinking alcohol. In these people, an enzyme that helps break down alcohol is inactive.
  • Limit your handling and eating of spicy foods, especially those derived from the Capsicum genus (peppers).
  • Try to avoid extreme temperatures and excessive bright sunlight.
  • Limit your niacin intake to the daily recommended allowance of 14 to 16 milligrams for adults, unless your healthcare provider tells you differently. Consuming more than 50 milligrams of niacin can cause flushing.
  • Employ coping skills to regulate extreme emotions, such as anxiety.

Helpful coping skills include relaxation techniques and cognitive behavioral skills. Also, hypnosis may be effective in treating some emotional issues that produce flushing.

In many cases, occasional flushing is more of a hassle than a medical concern. Taking preventive steps to address your flushing can be very helpful in reducing your symptoms.

However, it’s important to seek immediate medical care for unusual symptoms of flushing. You should also see your healthcare provider for recurring episodes, since flushing can be linked to serious medical conditions.

Talk to your healthcare provider if your flushing becomes a persistent issue or if it occurs with other symptoms, such as diarrhea.

Your healthcare provider will likely want to take an inventory of your symptoms to determine the underlying cause of your flushing. They may ask you about the frequency, duration, location, and context of your symptoms.

A medical exam and history will help supply required information for your healthcare provider to make a diagnosis. Be sure to mention other co-occurring symptoms, such as diarrhea, shallow breathing, or hives, so that your provider may evaluate them.

If your provider finds your symptoms are emotionally based, they may refer you to a psychotherapist. These professionals can teach you skills to help you cope with extreme emotional events and prevent flushing.
