Skin and stress: eczema, psoriasis and rashes under pressure

“Whenever things are at their worst, my skin flares up too. As if my body wanted to betray me completely.”

I hear this sentence, in different versions, more often than I would have expected. It is said by someone who has had eczema since childhood and knows it will flare again in the crook of their elbows before they defend their thesis. Or by someone with psoriasis who first noticed scaly patches on their scalp after their parents divorced. Or by someone who woke up during the most stressful week at work to find hives all over their stomach. They have two things in common: the skin reacted precisely when things were already hard — and all of them felt a little guilty about it, as if they should somehow have prevented it.

In this post I want to explain what we know about the link between skin and stress, why that link is not “all in your head”, and what psychotherapy can add to the treatment led by a dermatologist. It cannot replace it. I want to say that right at the start, too.

The dermatologist first, everything else after

Eczema, psoriasis, hives, acne, rosacea, hair loss — all of these are conditions with their own physical mechanisms and their own treatments. Some are chronic and come in flares; others may be a sign of an allergy, an infection, a hormonal imbalance or an illness that needs different treatment. A rash that appears suddenly and does not go away, a change in a mole, a wound that will not heal, or skin that becomes inflamed together with a fever and joint pain are all reasons to see your GP, who will refer you to a dermatologist if needed.

So the rule is simple: examination first, thinking about stress second. Not the other way round. Once there is a diagnosis and treatment is under way, though, something often becomes clear that almost everyone living with a chronic skin condition notices: it gets worse in periods of tension and better when life settles down. This is not imagination. But it is also easy to read the wrong way.

What psychosomatics means in the broader sense, what it means when the tests show nothing, and why the phrase “it’s just psychological” misses the point, I have described in more detail in “The tests are normal, but it still hurts”. This post is about something else: skin conditions that do have a clear diagnosis, and the question of why stress is so good at waking them up.

Skin and the nervous system share the same origin

As an embryo develops, the skin and the nervous system both form from the same germ layer, the ectoderm. It sounds like a curiosity from a biology textbook, but it says something important: the skin is not just a wrapping that separates us from the world. It is an organ densely woven with nerve endings, with its own immune cells, and it responds to the same stress hormones as the rest of the body.

When we are under pressure, the axis between the hypothalamus, the pituitary gland and the adrenal glands is activated and releases cortisol. In the short term this is useful: the body prepares for effort. But when stress lasts for weeks and months, the balance of the immune system shifts. For people with inflammatory skin conditions, this means a fire that is already smouldering is easier to fan. Researchers also describe local pathways: nerve endings in the skin release substances that activate mast cells — the cells responsible for the itching and swelling of hives.

One of the clearest studies on this was carried out with students during exam period. Researchers carefully removed the top layer of skin with adhesive tape and measured how quickly the skin barrier recovered. During exams, when students reported more stress, the barrier recovered more slowly than during the holidays. For people with eczema, whose skin barrier is already weakened, this is an important part of the story: stress does not “cause” eczema, but it makes it harder for the skin to repair itself.

A circle that keeps turning by itself

The biggest trap with skin conditions and stress is not that stress makes the skin worse. The trap is that the opposite happens too — and that the two currents start feeding each other.

When the skin itches, we scratch. Scratching brings relief for a few seconds — sometimes almost pleasure — and then the skin becomes more inflamed, the itch grows stronger and small sores appear. At night, when there is nothing to divert your attention, the itch is louder; sleep becomes shallow and broken. Someone who has not slept is more irritable the next day and less resilient to stress. And when the stress is greater, the itching rises again.

Then comes a layer people talk about less: how you feel around others when you have a visible skin condition. Many start wearing long sleeves in summer and avoiding swimming pools, intimacy, photographs, handshakes. Each of these retreats is understandable. But they are part of the circle too — the more you hide, the more time you spend alone with thoughts about your skin.

When skin becomes a subject of shame

Skin is an organ other people can see. With back pain, you can decide whom to tell. With psoriasis on your hands or eczema on your face, you cannot. That is why shame is so common with skin conditions — the feeling that something is wrong with you and that others will reject you for it.

A large European study of dermatology outpatients in thirteen countries found that around ten per cent of patients with skin conditions met the criteria for clinical depression — compared with less than half that proportion in a control group without skin conditions. Rates of anxiety and suicidal thoughts were also higher. This does not mean that skin conditions “cause” depression, but it does show that the burden of a skin condition is much greater than what is visible on the skin.

People who have had eczema since childhood often carry something else with them: the memory of how their parents responded to their skin. Some remember constant warnings — “don’t scratch” — hands being pulled away from their face, creams applied at bedtime in a way that was both tender and full of worry. Others remember classmates’ teasing. These experiences shape a relationship with one’s own body that lasts long after the skin calms down. I have written about how body image changes over a lifetime in Self-image and ageing: when your body and roles change.

When you feel it is your own fault

A common sentence goes something like this: “If stress makes my skin worse, then it’s my fault for not being able to calm down.” The thought is understandable, but wrong — and it becomes a new source of stress in itself.

Stress is only one factor. Flares are also triggered by infections, weather, dry air during the heating season, hormonal changes, some medicines, allergens and often nothing you could identify at all. If the skin reacted only to stress, people with skin conditions would be free of symptoms in calm periods. Most are not. So there is no point in looking for someone to blame. The useful question is which of the many things affecting your skin are within your influence — and stress is one of the few that are.

Here it helps to know the difference between guilt and responsibility. Guilt says: “I did this to myself.” Responsibility says: “I can’t choose whether I have psoriasis, but I can choose how I look after myself while I have it.” The first thought paralyses; the second opens space for action.

What happens in relationships

In relational work I am also interested in how a skin condition lives within relationships. Because it is visible and touched, it is often present in everyday moments between partners. Some people withdraw from touch during a flare, and their partner reads it as rejection. Others start “monitoring” their partner with questions about whether they have put the cream on, whether they have been scratching again. What starts as care can turn into a dynamic in which one feels like a child and the other like an exhausted carer.

In therapy, such a conversation might sound like this (a composite, not a real person):

“I can’t stand her asking whether I’ve put the cream on any more. As if I were a child.”
“What happens inside you when she asks?”
“It’s as if she only sees my skin. Not me.”
“And what do you think she feels before she asks?”
Silence. “She’s probably scared. Last year I was in hospital with an infection.”
“Perhaps you could tell her what you need instead of the question.”
“That sometimes she just holds me. Even when I look like this.”

In a moment like that, skin stops being only a medical subject and becomes a bridge to something that has long gone unsaid: fear, the need to be accepted, sadness that the body is not the way we would like it to be.

What research shows about psychological approaches

The field that deals with the link between skin and mind is called psychodermatology. Its studies are smaller than drug trials, but a few findings are convincing enough to mention.

In one of the most frequently cited studies, people with psoriasis receiving light therapy listened to a guided mindfulness meditation during their treatment sessions. In those who meditated, the skin cleared faster than in those who received light therapy alone. The study was small and should be read with caution, but it opened a question researchers are still exploring today.

A research team in the United Kingdom offered people with psoriasis a cognitive-behavioural symptom management programme alongside their usual treatment. Compared with a group receiving usual treatment alone, participants reported less distress and fewer everyday limitations, and the severity of their symptoms also improved. Similar approaches are used for atopic dermatitis, including habit reversal training for scratching.

Importantly, none of these studies shows that psychological work could replace skin treatment. They only show that it can help it along.

So in therapy I do not promise clear skin. What we can do together is explore when the flares come, what is happening in your life and relationships at those times, how you talk to yourself when you look in the mirror, and what could help you break the circle before it turns all the way round.

Exercise: a diary of your skin and your day

This exercise is not meant to help you find the “real” cause. It is meant to help you start noticing patterns you cannot see in the everyday rush. You need a notebook or your phone and a few minutes each evening for at least two weeks.

1. Rate your skin on a scale from 0 to 10 — itching, inflammation, how much you notice it. Don’t think too long; write down the first number.
2. Rate your day on the same scale: how much tension, pressure or worry it held. Write one line about what was hardest.
3. Note when you scratched the most and what you were doing or thinking at the time. It often turns out that scratching is a response not only to itching, but also to boredom, anger or restlessness.
4. Choose a substitute for that moment. Clench your fist for thirty seconds, apply a cool compress, press the itchy spot with your palm instead of scratching it. Note whether it helped.
5. After two weeks, look at the whole record. What do you notice? Does your skin get worse a day or two after a tense event? Or the reverse — does worry rise only once the skin gets worse? You can take this to your dermatologist too.

If self-criticism shows up along the way (“I scratched again, I have no willpower”), don’t take it literally. The diary is observation, not judgement. For more on how to treat yourself more kindly when something doesn’t work out, see the entry on self-compassion.

Where this story does not apply

I want to be honest here, because public talk about the link between skin and mind is full of oversimplifications.

Not every skin problem is linked to stress. In some people the condition changes not with periods of tension but with the seasons, hormones or exposure to allergens. If after a few weeks your diary shows no connection, that is valuable information too. Let’s not force the skin into a story that isn’t there.

Calming down is not a treatment for inflammation. Even the calmest person with moderate or severe psoriasis needs treatment. Biologic medicines and other modern treatments have changed many people’s lives — and if someone tells you that you don’t need them because you have to “sort out your emotions first”, that is not good advice.

“The skin is the mirror of the soul” is a lovely sentence, but as an explanation of illness it can do harm. If the skin really were the mirror of the soul, people with psoriasis would be less at peace with themselves than others. They are not. They have a condition that stress can make worse — just as stress can make asthma or diabetes worse.

When thoughts appear that you can’t go on, talk to someone. In Slovenia, the crisis line Klic v duševni stiski is available on 01 520 99 00 (every day from 7 pm to 7 am), and the Samaritans helpline Zaupni telefon Samarijan on 116 123 (24 hours a day). In an emergency in Slovenia, call 112.

How to decide whether to talk to a therapist

Psychotherapy can make sense when you notice that you are withdrawing from people because of your skin, that shame or worry about your skin takes up a large part of your day, that you have had trouble sleeping for weeks, or that your skin is causing friction in your relationship. It can also make sense when skin problems appear during a period of major life change — a separation, a loss, the birth of a child, a new job — and you feel your body is carrying more than you can manage. I also work with English-speaking clients in person in Ljubljana.

If, on the other hand, you notice that your main worry is whether it might be something more serious, and that worry does not go away even after examinations, you may find Health anxiety: when every symptom means the worst helpful. If your skin condition comes with long-lasting fatigue, low motivation and pain, read Depression and the body: pain, fatigue and digestion.

Psoriasis is an immune-mediated condition, so a related question is what role stress plays in other immune conditions — that is the subject of Autoimmune disease and stress: what the research really shows. Which methods genuinely calm the body is gathered in How the body calms down: methods with evidence, not just advice.

What to remember

• With any skin problem, see your GP and dermatologist first — stress is not a diagnosis.
• Stress does not “cause” skin conditions, but it can weaken the skin barrier, intensify itching and trigger a flare in an existing condition.
• Itching, scratching, poor sleep and shame form a circle that can be broken at several points.
• Psychological approaches can complement skin treatment, but not replace it.
• A flare is not your fault. But you can choose how you look after yourself when it happens.
