Why Psoriasis Flares Up
Many people living with psoriasis notice that their symptoms can appear to worsen without warning. One day the skin may seem relatively calm, and the next day redness, itching, or scaling may suddenly increase. These sudden changes are known as psoriasis flare ups.
A flare up occurs when psoriasis symptoms become more active or severe for a period of time. While psoriasis is a chronic condition that tends to come and go, flare ups can often be linked to specific triggers such as stress, illness, environmental changes, or skin irritation.
Understanding what causes psoriasis flare ups can help people manage the condition more effectively and reduce the likelihood of sudden worsening symptoms.
What Is a Psoriasis Flare Up?
A psoriasis flare up refers to a period when symptoms temporarily worsen. During a flare up, people may experience:
-
Increased redness or inflammation
-
Thicker plaques forming on the skin
-
More intense itching or irritation
-
Increased skin scaling or flaking
-
New patches appearing in previously unaffected areas
Flare ups can vary greatly from person to person. Some people may only experience mild increases in symptoms, while others may develop widespread plaques that require additional treatment.
Learning about the different psoriasis treatment options available can help people manage flare ups when they occur.
Common Psoriasis Triggers
Although flare ups sometimes seem random, they are often linked to identifiable triggers. Recognising these triggers can help reduce the frequency or severity of flare ups over time.
Stress
Stress is one of the most commonly reported psoriasis triggers. Emotional stress can affect the immune system, which may increase inflammation in the body and contribute to psoriasis symptoms.
Periods of high stress can sometimes lead to flare ups that appear suddenly, especially if other triggers are also present.
Skin Injury
Injury to the skin can sometimes trigger psoriasis patches in the affected area. This phenomenon is known as the Koebner response.
Examples of skin injuries that may trigger flare ups include:
-
Cuts or scratches
-
Sunburn
-
Insect bites
-
Skin irritation from harsh products
Because the scalp is particularly sensitive, irritation in this area can also worsen symptoms related to scalp psoriasis causes and treatments.
Weather Changes
Cold and dry weather conditions can sometimes make psoriasis symptoms worse. During winter months, lower humidity levels may dry out the skin and increase irritation.
Reduced sunlight exposure during colder seasons may also contribute to flare ups for some individuals.
Illness or Infection
Certain infections can trigger psoriasis flare ups. In particular, infections such as strep throat have been associated with sudden psoriasis outbreaks in some people.
When the immune system becomes more active during illness, psoriasis symptoms may temporarily worsen.
Why Flare Ups Sometimes Seem Random
Even when someone understands their common triggers, psoriasis flare ups can still appear unpredictable.
This is because psoriasis is an autoimmune condition, meaning the immune system plays a central role in the development of symptoms. Changes in immune activity, hormonal shifts, stress levels, and environmental factors can all influence when flare ups occur.
For some individuals, flare ups may develop after a combination of triggers rather than a single cause.
According to the National Psoriasis Foundation’s guide to psoriasis triggers, many people experience flare ups when multiple contributing factors occur at the same time.
How to Reduce Psoriasis Flare Ups
While it may not always be possible to prevent flare ups completely, certain lifestyle habits may help reduce their frequency.
Managing Stress
Stress management techniques such as exercise, meditation, or relaxation practices may help reduce stress-related flare ups.
Protecting the Skin
Avoiding harsh skin products and protecting the skin from injury may help minimise irritation that could trigger psoriasis patches.
Maintaining Skin Hydration
Keeping the skin moisturised may help reduce dryness and scaling, which can make psoriasis symptoms more noticeable.
Identifying Personal Triggers
Tracking flare ups and identifying potential triggers can help people better understand patterns in their symptoms.
When to Consider Treatment Options
For some individuals, flare ups may occur frequently or become difficult to manage with basic skincare alone.
In these cases, exploring different treatment approaches may help control symptoms. Options may include topical treatments, medicated shampoos, or light-based therapies.
Some people also explore treatments such as UVB light therapy treatment, which can help slow skin cell growth and reduce inflammation associated with psoriasis.
For individuals experiencing scalp symptoms during flare ups, using products such as a coal tar psoriasis shampoo may help support scalp care as part of a broader management approach.
Final Thoughts - Why Psoriasis Flares Up
Psoriasis flare ups can be frustrating and unpredictable, but understanding common triggers can help people manage their symptoms more effectively. Stress, skin irritation, infections, and environmental changes are all known factors that may contribute to flare ups.
While flare ups cannot always be prevented, identifying personal triggers and exploring suitable treatment options can help reduce their impact over time.
Because psoriasis affects everyone differently, finding the right combination of treatments and lifestyle adjustments may take time. By learning more about triggers and management strategies, many people are able to better control their symptoms and reduce the frequency of sudden flare ups.
