Dyshidrotic Eczema Treatment in Dubai: Why Summer Makes Pompholyx Worse
A woman came to me a few years ago having just resigned from a job she had held for fourteen years. Nothing was wrong with her work. She simply could not keep shaking hands with clients. The tiny blisters across her palms had become something she felt she had to hide, and she had spent months keeping her hands behind her back when meeting anyone new.
That is dyshidrotic eczema. And in Dubai, it has a season.
What is dyshidrotic eczema?
Dyshidrotic eczema is a form of eczema that produces small, deep-set, fluid-filled blisters on the palms, fingers and soles. The blisters look like sago beads sitting just under the skin. They are intensely itchy, often painful, and they tend to appear in crops rather than one at a time.
The word breaks into Greek roots — dys (disordered) and hidros (sweat) — literally “disordered sweating.” For a long time it was believed that sweat alone caused it. It doesn’t, though sweat is very much part of the picture. It is related to but distinct from hyperhidrosis, which is excessive sweating without the blistering.
You will also hear it called pompholyx, from the ancient Greek pomphólux, meaning a water bubble or blister. It is pronounced POM-fuh-licks.
One thing worth knowing early: unlike ordinary eczema, which usually builds over months or years, dyshidrotic eczema can go from nothing to full flare in a matter of weeks.
Why Dubai makes pompholyx worse
This is the part most articles written elsewhere will never tell you, because they aren’t written for people living here.
The 45°C to 22°C shock
From June to November, outdoor temperatures in Dubai routinely sit above 40°C, and peak days push past 45°C. Your home and office are set to 22 or 23°C. Every time you walk out of a mall into a car park, or step off the street into a lobby, your skin absorbs a swing of more than twenty degrees in a few seconds.
That repeated shock is one of the biggest triggers I see. Not the heat on its own, and not the air conditioning on its own — the sudden switching between them, several times a day, all summer.
Handwash — and not just in the malls
Public washrooms in shopping centres use industrial-strength handwash, and people with pompholyx react to it almost immediately. But don’t stop there. The soap sitting on your own bathroom and kitchen sink is very often doing exactly the same thing, just more slowly, so you never connect it to the flare.
Construction dust and mould at home
Dubai construction dust is unavoidable — it is genuinely everywhere. What compounds it is mould, and almost every home here has some. It grows quietly inside the AC ducting, which is dark, cool and damp for months at a stretch. You cannot see it, but you are breathing it every night.
I’ve written separately on whether mould can make you sick and on environmental allergy treatment in Dubai, both of which go deeper on this.
Metals you touch without thinking
Nickel and cheap alloys are a classic trigger. Door handles, car door handles, lift buttons, keys, the underside of a desk drawer. You touch dozens of them a day without registering a single one.
The hidden triggers nobody finds on their own
Here is where people get stuck. They correctly identify heat and sweat, remove what they can, and still flare. That’s because there are layers of sensitivity underneath that produce no itching at the moment of exposure — so there is nothing to connect the dots with.
The common ones I find in the centre are dairy, wheat, nuts, and a plant protein called lectin, which is present in beans, pulses, grains and nightshades and rarely gets tested for at all.
Stress belongs on this list too. I have not met a person with pompholyx who wasn’t carrying a significant load of stress or anxiety. It is difficult to say which came first, and after a while it stops mattering — the two feed each other. It also tends to show up in adults far more than in children, and often in families where a sibling or parent has eczema or asthma. Both point to the same underlying picture: an immune system set to overreact.
Why IgG and IgE blood tests rarely give you the whole answer
They are useful. They are not sufficient.
A blood panel tells you what your antibodies are doing on the day of the draw. It will not capture heat, humidity, sweat, sudden temperature change, a specific handwash, or the mould in your bedroom vent — and for many of my clients, those are the dominant triggers. Working from blood results alone, people spend months or years eliminating foods one at a time and still can’t explain their flares.
If you want a sense of what testing actually costs here before you commit, I’ve laid it out in allergy testing cost in Dubai.
What gives relief while you’re finding the root cause
Steroids work like magic in the short term. That is exactly the problem — overuse thins the skin and, for some people, the rebound flare is worse than where they started. These are the measures I give people to hold the line while we do the slower work:
- Ice. Keep a pack in the freezer at all times. On a bad summer day it is the fastest relief you have.
- Potassium permanganate soak. Fifteen minutes, every alternate day, soothes the skin and helps prevent cross-infection. It must be diluted to a pale pink — roughly 1:10,000. Undiluted crystals will burn the skin, so please get the dilution shown to you once before doing it at home.
- Red light therapy. In the centre we use 1060 nm gated at 40 times per second, every three days. It takes the edge off the itch.
- Colloidal silver spray at 10 ppm, applied topically to open cracks, keeps bacterial growth down while they close. Topical only — never taken internally.
- Cotton socks over Crocs. Crocs are the single worst offender I hear about; the itch inside them at a desk is unbearable. Cotton socks at home give real relief.
- Bach flower remedies for the stress layer. There are 38, and the right one is almost always a combination — see a kinesiologist or someone trained in muscle response testing rather than guessing.
- Switch your bedding and washing to hypoallergenic — pillow covers, bed covers, duvet covers, soap and shampoo. Note that “natural” and “organic” are not the same as hypoallergenic, and in this condition they often don’t help at all.
How NAET identifies the triggers and desensitises them
Nambudripad’s Allergy Elimination Technique uses applied kinesiology — muscle response testing — to find what your body is actually reacting to, including the things a blood panel can’t see. Combined with bioresonance, it gives us a way to test heat, humidity, sweat, dust, mould, metals and foods directly.
We then desensitise them one at a time, starting with the Basic 15. Those fifteen are the foundation; they stabilise an overreactive immune system before we go after the specific environmental triggers.
I’ll be straight with you about the caveat: this takes time. It is not a quick fix. Steroids will clear your hands faster than I can. What NAET is trying to do is different — remove the reason your hands are blistering in the first place, so that next June doesn’t look like this one.
If you want the fuller explanation of the method, start with allergy elimination: is it possible with NAET? and natural eczema relief in Dubai: getting to the root cause. If stress is the piece you recognise most, read stress-induced allergy.
Frequently asked questions
No. It is an immune reaction, not an infection. You cannot pass it to anyone by shaking hands.
A typical crop of blisters runs two to four weeks, drying and peeling before it clears. Without addressing triggers, flares recur — in Dubai, most often through the summer months
There is no overnight cure. What can change is your reactivity. When the underlying sensitivities are identified and desensitised, flares become less frequent and less severe, and for many people stop returning.
Heat, humidity, sweat and the repeated swing between 45°C outdoors and 22°C indoors are all direct triggers. Construction dust and AC mould peak in the same months.
It is a type of eczema, but it behaves differently — deep blisters confined to hands and feet, and a much faster onset, weeks rather than years. More on the differences in eczema treatment in Dubai.
