Why Stress Can Make Psoriasis Flare And Why Scratching Makes It Worse

Psoriasis is often described as a skin disease, but anyone who lives with it knows that the problem does not always stay on the skin. Stress, poor sleep and the constant irritation from itching can all become part of the picture. And sometimes, a flare can become another source of stress, creating a cycle that is difficult to break.

Stress does not cause psoriasis in everyone, and it is certainly not the reason someone develops the disease. But for people who already have psoriasis, emotional and physical stress can trigger or worsen a flare. We spoke to Dr Sunitha Pendyal, Senior Consultant-Clinical & Aesthetic Dermatologist, KIMS-Arete Hospital, who shared link between stress and psorisis flare.

Why does stress affect the skin?

"Psoriasis involves an overactive immune response that causes skin cells to build up much faster than normal. Stress can influence inflammatory pathways in the body, and in some people this seems to be enough to set off a flare or make an existing one worse," said Dr Pendyal.

It is not always a major life event that does it. A demanding period at work, poor sleep, family problems or simply being under pressure for weeks can sometimes be enough. Different people have different triggers, which is why there is no single list that applies to everyone.

"This is also why telling someone with psoriasis to 'just relax' is not particularly helpful. Stress management can be useful, but it should be part of managing the disease, not a substitute for treating the psoriasis itself," added Dr Pendyal.

The itch-scratch cycle is real

Itching can be one of the most frustrating symptoms of psoriasis. The natural reaction is to scratch, especially when the itch is keeping someone awake or becoming difficult to ignore.

"The problem is that scratching injures the skin. That injury can make the existing psoriasis worse and, in some people, can cause new psoriasis lesions to appear at the site of the injury. This is known as the Koebner phenomenon. Scratching can also make plaques thicker and, particularly with scalp psoriasis, can lead to bleeding and temporary hair loss," explained Dr Pendyal.

So there is often a frustrating cycle: the psoriasis itches, scratching gives temporary relief, the skin gets irritated, and the psoriasis becomes harder to settle.

"The best way to stop scratching is often to get the psoriasis under control. Moisturising regularly can help with dryness, while treatment prescribed by a dermatologist can reduce the inflammation and itching itself. A cold compress can also provide short-term relief when the urge to scratch is particularly strong," advised Dr Pendyal.

It is also worth paying attention to what happens before a flare. Some people notice a clear connection with stressful periods, while others may find that infections, certain medicines, weather changes, alcohol or smoking are more important triggers. Keeping a simple record can help identify a pattern.

Don't blame yourself for a flare

One of the more difficult aspects of psoriasis is that the skin can become a visible reminder of something that may already be causing emotional stress. A flare can affect confidence, sleep and social life, which can add to the stress that may have triggered it in the first place.

The answer is not to eliminate every stressful situation - that is rarely realistic. It is to treat the psoriasis properly, protect the skin from unnecessary injury and find practical ways of managing stress.

"Psoriasis is a chronic condition, and occasional flares can happen even when someone is doing everything right. The aim is not to blame stress or scratching for the disease, but to recognise that both can make an existing problem harder to control," concluded Dr Pendyal.
