Hard Water in Indian Cities and Psoriasis: Is Your Tap Water Silently Worsening Your Skin? – Several years ago, I treated a patient who asked me a rather simple question.
“Doctor, my psoriasis gets worse every time I am in the city. Is my water the problem?”
This may sound like a weird question, but when I started asking him about his daily activities, it made sense.
He said that he started feeling his skin tighter whenever he took a shower. His skin was dry, sometimes itchy, and the psoriasis rash was aggravated. He had changed the soaps. He had tried different creams. He even made some dietary changes.
However, no one ever thought about the water that he used every day. This made me realise how often we fail to pay attention to something as important as the water we bathe in.
In several Indian cities, people experience the problem of hard water, which refers to water that has more minerals, like calcium and magnesium. Depending on the water source, the hardness of the water in Indian cities may vary drastically.
So we are led to ask the question:
Is it really true that hard water may aggravate psoriasis?
The answer to this must involve some explanation. Hard water does not cause psoriasis, nor does psoriasis occur in someone who simply makes use of hard water. Psoriasis is a chronic immune-mediated ailment. However, hard water may worsen dryness of the skin and may contribute to the damage the skin barrier sustains.
What is hard water?
Hard water is water that has a high content of dissolved substances, particularly the salts of calcium and magnesium. Many individuals recognise hard water without knowing that it is hard.
You may notice:
- White deposits on taps
- Mineral marks on bathroom fittings
- Soap that does not foam properly
- A rough or sticky sensation on the skin after a bath
- Dry skin after a shower
The water itself may seem to be perfectly normal, but the mineralisation of the water may be high. That is why hard water is often an invisible aspect of our everyday life.
Does hard water contribute to psoriasis?
No, hard water is not believed to cause psoriasis. The disease happens due to an unusual response of the immune system and genetic disposition, environmental factors and others. There is, however, a considerable distinction between the cause of psoriasis and the aggravation of the disease.
For instance, assuming your skin is already affected by psoriasis, exposure to hard water may enhance the feeling of discomfort. To put it another way, if we draw an analogy between healthy skin and a protected wall, we can conclude that psoriasis and dry skin would weaken that protection.
When this happens, any subsequent irritants will contribute to the disease, further aggravating the situation. This is the reason why I do not tell my patients that their water is the only reason for psoriasis, but I make them consider the problem from a wider perspective.
What is it about hard water that causes dry skin?
The main reason behind this might lie in how minerals in hard water affect soaps and other cleaning agents. Hard water makes rinsing soap and other cleansers more complicated. Because of this, some individuals will notice that their skin feels dry, tight or irritated after washing.
The situation sounds uncomfortable for a person without any skin problems. Yet for someone having psoriasis, the additional irritation from hard water becomes more pronounced, considering the fact that skin is already dry, sensitive and irritated.
A patient’s bathing routine matters too
However, it doesn’t mean that all people suffering from psoriasis will react to hard water in the same way. Importance of Patient Bathing Habits: It is not uncommon for patients to complain about water quality. However, when their routine is examined, it becomes clear that there may be a lot more to the situation. Patients often take extremely hot showers. They may spend a lot of time soaking in the tub. They usually apply strong soaps. They may be scrubbing the patches of psoriasis too vigorously. They may continue scratching their skin if it becomes itchy. All of the above can bring about dryness of the skin, leading to irritation.
Therefore, before blaming water only, it makes sense to reconsider one’s bathing habits. A little change, such as using warm water instead of very hot water or avoiding strong soap, can make all the difference in comfort.
To what extent can hard water lead to psoriasis flare-ups?
Well, it is important to be clear about what research tells us. At this point, there is no conclusive evidence linking hard water to the occurrence of psoriasis flare-ups. However, anything that contributes to skin irritation or dryness may exacerbate existing symptoms.
Psoriasis may develop due to various factors, such as the following:
- Stress;
- Trauma to the skin or scratching;
- Infections;
- Not getting enough sleep;
- Some medications;
- Smoking;
- Drinking alcohol;
- Changing seasons;
- Personal triggers.
So when moving to a place with hard water, remember that it may not necessarily be the cause of psoriasis worsening. Changes in personal lifestyle, environmental factors, stress and many other things may play a role.
Should you install a water softener?
This is a question I get asked a lot by patients. There is no standard answer to the question of whether a person with psoriasis should install a water softener. Truth is, if you struggle with hard water and have issues with dry or irritated skin after bathing, you might want to consider improving that situation.
But I certainly wouldn’t want my patients spending ridiculous amounts on a water-softening solution when it is easier and cheaper to practice good skin care and treat psoriasis right.
Start with the basics:
- Use warm water.
- Do not spend too much time in the shower.
- Pick a mild soap.
- Do not rub or scratch the skin that is affected by psoriasis.
- Make sure to moisturise your skin right after bathing.
- If the skin continues to be irritated, visit your doctor.
- Moisturising Is Superior to Water-Cry Blaming
The simplest piece of advice I have always given to people with psoriasis is to moisturise on a regular basis.
Moisturising is more important than blaming the water
Skin that is prone to psoriasis is usually dry, as it is often hard to maintain the skin barrier, and it is very important for the everyday skincare routine. After taking a bath, it is better to pat the skin gently instead of rubbing it with a towel.
Following this step, apply a good moisturiser to the skin while it is still damp. This will help to prevent the skin from becoming dry and uncomfortable to some extent. The only thing is that many of my patients spend an enormous amount of time trying to find the most effective water filter but forget about this simple habit.
What to do if you see your psoriasis getting worse?
If you find that your psoriasis is getting worse over time, don’t just think that hard water is to blame.
Think and ask yourself these questions:
- Have I had a lot of stress lately?
- Am I getting enough sleep?
- Have I been injured or scratched?
- Have I changed any of my treatments or products?
- Have I experienced an infection in recent times?
- Has the weather changed?
- Have I experienced changes in my lifestyle?
- And, of course, am I following my doctor’s advice when being treated for my condition?
- When is it Necessary to Seek Medical Attention?
If your skin still has dry, itchy, painful, or inflamed spots even after a careful skin care routine, you must see a doctor.
You should also see a doctor when:
- Visible areas of psoriasis are spreading or getting worse
- There are new patches appearing
- There are cracks or sores
- Your nails are changing
- You haven’t been able to move joints normally
- Your symptoms are disturbing your sleep
- Your current therapy is not working
Remember, not all itchy and dry spots on your body are psoriasis. Some other skin conditions have similar appearances, and a diagnosis is essential.
Conclusion:
Does your tap water negatively affect your psoriasis? Hard water itself does not cause psoriasis but can worsen dermatitis in people whose skin is already dry or damaged. Instead of worrying about your water quality, focus on taking good care of your skin.
Remember to use mildly warm water, avoid harsh soaps or scrubbing your skin too much, and keep the skin well-hydrated and protected from injury. If you know you are living in an area with hard water and your skin gets dry or irritated after taking a shower, ask your doctor about it and whether improving the quality of your water can help.
In fact, psoriasis can rarely be managed by just changing one thing. The aim is not to be afraid of your tap water but to learn about your skin and how to take care of it.
Frequently Asked Questions
1. Can hard water cause psoriasis?
No. Hard water is not considered a direct cause of psoriasis. Psoriasis is a chronic immune-mediated condition influenced by genetic, environmental, and other factors. However, hard water may contribute to skin dryness or irritation in some people, which can make already sensitive psoriasis-prone skin feel worse.
2. Can hard water make psoriasis worse?
Hard water has not been proven to directly cause psoriasis flare-ups. However, the minerals in hard water, combined with soaps or cleansers, may contribute to dryness and irritation. For someone who already has psoriasis, this may increase skin discomfort.
3. How does hard water affect psoriasis-prone skin?
Hard water contains minerals such as calcium and magnesium. It may interact with soaps and cleansing products and can sometimes leave the skin feeling dry or irritated. Since psoriasis can already compromise the skin barrier, additional dryness may make the skin feel more uncomfortable.
4. Is bathing with hard water bad for people with psoriasis?
Not necessarily. Many people with psoriasis live with hard water without experiencing a noticeable problem. If you regularly experience dryness, itching, or irritation after bathing, however, your bathing habits and water quality may be worth discussing with a doctor.
5. Should people with psoriasis avoid hot showers?
Yes, it is generally better to avoid very hot and prolonged showers if you have psoriasis-prone skin. Hot water can increase dryness and irritation. Lukewarm water is usually a better choice for maintaining skin comfort.
