What Is Urticaria?
Urticaria, commonly referred to as hives, is a skin reaction characterised by raised, itchy welts. These welts can vary in size and shape, and may appear suddenly, either as a single episode or as recurring outbreaks over time. The condition may last minutes, hours, or even persist for days depending on the trigger and individual skin response. While the appearance can seem alarming, urticaria is not considered contagious.
How Hives Present on the Skin
Hives typically show up as red or pale raised areas on the skin’s surface. These marks often shift locations, come and go quickly, and may merge into larger patches. Unlike other forms of rash, hives can be triggered by internal factors such as allergies, stress, or temperature shifts, not just contact with external irritants. Understanding the differences between urticaria vs rash can help clarify why hives behave in such a temporary and shifting way.
Types and Triggers
There are several types of urticaria. Acute urticaria often occurs in response to allergens or infections and resolves within a short time. Chronic urticaria, however, persists for six weeks or more and may not have a clearly identifiable cause. Physical urticaria can be triggered by pressure, cold, heat, or sunlight. Because the condition varies widely, many turn to urticaria specialists to help identify patterns or hidden contributors. Although hives are not contagious, they can seem unpredictable without a clear source.
Living with Urticaria
The spontaneous nature of hives can be distressing. Whether they appear once or recur over months, urticaria often brings both physical irritation and uncertainty. The sensation of itching or burning may interfere with sleep or comfort, especially during flare episodes. For those who experience frequent outbreaks, even mild cases can raise questions about long-term skin sensitivity, environmental triggers, and underlying factors. Knowing the type of urticaria involved can offer valuable clarity.
