If you’re a regular reader of this blog, by now you’ve gathered that anxiety is more than just a psychological issue and can manifest itself in a myriad of different ways. One unusual physical symptom sometimes attached to anxiety is the way fear can cause you to itch or break out with a rash or hives.
Anxiety can cause or make skin problems worse
The itchiness can be related to skin problems that anxiety makes worse, or caused by anxiety directly. People can even experience stress urticaria, or stress hives, that develop due to chronic stress, anxiety or tension, and appear as red, raised and swollen areas on the skin that appear suddenly. These stress hives can cause itching, and some people report having a burning or stinging sensation whenever they appear. Stress hives can appear on any part of the body – face, hands, feet, arms, etc., – and can vary in size from as small as a pencil eraser to as large as a dinner plate. Stress hives have been known to spread from place to place on the body, and smaller areas of hives can blend together to form larger areas. Urticaria can be acute, meaning that hives last less than six weeks, and also chronic, which is when hives last longer than six weeks.
Stress and your immune system
Itchy skin or hives caused by anxiety aren’t exactly “common” in the general sense, but anxiety causes a significant amount of stress, and stress can have a detrimental effect on organs and on the body’s immune system. Since the skin is the largest organ on the body, anxiety can lead to a rash, hives, and an overall itchy feeling. Furthermore, when the immune system starts to falter from stress, it starts sending histamine into the body to fight off what is ailing it – all the anxiety. So, in the simplest terms, the body forms an allergic reaction to stress. The stress can’t be eliminated with histamine, so the histamine causes hives to appear on the body.
Connection between stress and urticaria
Dermatologists are learning that there is a definite link between the mind, the immune system and the skin. More research is focusing on the relationship between stressful life events and the onset of urticaria. Dermatologists are seeing that it’s not uncommon to see urticaria occur after a major life stressor, or that the patients who are most impaired by urticaria have more limited stress management skills. They can see a connection in patients with relatively minor dermatological symptoms and a seemingly disproportionate amount of distress about these symptoms, which might suggest the patients don’t have the capacity to recognize the psychological component to their distress and/or suffering.
Examples of stress related skin problems
It’s very difficult to determine the exact cause of itchiness from anxiety without a full examination, because it could be caused by a variety of different factors. But, the most common causes include:
- Stress hives. As previously mentioned, hives are itchy bumps on the body that can be triggered by stress. Anxiety causes a considerable amount of stress on the immune system, so those prone to hives are likely to get them.
- Sweat rash. Anxiety also causes sweating, and sweating can lead to a sweat rash, otherwise known as a heat rash. This type of rash is non-threatening, but can be extremely itchy and may take as long as two weeks or more to disappear.
- Specific triggered itch. Although less common, anxiety also triggers skin conditions that a person already has. Anxiety is known to trigger eczema, herpes, psoriasis, and other skin disorders. None of these is life threatening or dangerous if triggered.
- Worse or heightened sense of itch. Itching and rashes are fairly common experiences in life, even when nothing is the matter. However, if one suffers from anxiety, physical sensations can often feel worse than they would if he/she didn’t suffer from anxiety. Thus, it’s possible that a very light rash that could otherwise be ignored feels much worse, and causes the person to focus on it more.
- Unexplained. It’s also possible to experience an itch for reasons that simply can’t be explained.
What to do about it
At any time, if your stress hives are coupled with swelling of any part of the throat or face and it causes restricted breathing, you should seek treatment immediately from your closest emergency room.
Some cases of hives will go away on their own without any course of treatment. If something is definitively causing a person to experience hives, the doctor will recommend avoiding that trigger. Particularly with stress hives, the trigger that is causing anxiety needs to be addressed with the help of a trained therapist.
If hives are very itchy, the doctor may recommend taking an antihistamine (medicine) to block the release of histamine to the bloodstream. It may take some time for your doctor to help you find the right treatment. Most of the time, once the anxiety trigger(s) are addressed, hives will go away on their own. Even chronic hives can sometimes clear up on their own within a few months to a year. Stress hives have shown significant improvement with histamine when treated with relaxation techniques and other anxiety management tools.
