A Story From the Field: "The Water Is Gone, but Mum Won't Come Inside"

Prae is in her thirties and lives with her mother, who is in her early sixties, in a modest one-and-a-half-storey house down a narrow soi in Pak Kret, Nonthaburi, not far from the Chao Phraya River. During the 2026 floods, the water came in roughly knee-high and stayed for almost two weeks. The two of them moved in with relatives across town. When the water finally went down, Prae came back alone to shovel out the mud, hose down the floors and drag the swollen wardrobe to the curb. She did everything she thought she was supposed to do.

What she was not prepared for was her mother. On the day they came home together, her mother stopped at the front door, looked at the long brown waterline that ran straight across every wall, and said quietly, "I don't want to go in yet. It smells just like the night the water came." That first night back, her mother woke up again and again, walking to the front room to check whether the water was rising. Every time it rained, her heart raced. Prae, exhausted from days of cleaning, found herself snapping at her mother over small things, something that had almost never happened before.

In her mother's bedroom, a ring of black mold spots had spread across the wall behind the wardrobe. The old mattress, lifted onto a table in time, still smelled damp. The curtains had been washed twice and still smelled sour. Every breath seemed to carry the house back to that night. "We've cleaned it three times," Prae said, "but it still doesn't feel like our home."

Prae's story is not unusual. Many families across Nonthaburi and the wider Bangkok area are living some version of it right now. The water has gone down, but the worry has not. In this article we look at why the condition of a home after a flood can weigh so heavily on the mind, how a clean, odor-free, mold-free home can help people rest and start to recover, and how you do not have to carry all of this alone.

Why a Flooded Home Can Be More Stressful Than You Expect

Feeling stressed after a flood is a common and understandable reaction to going through something big. It does not mean you are weak. Many people notice that they struggle to fall asleep, startle easily, feel tired even when they have not done much, or simply feel numb. The state of the house can make these feelings last longer, for several reasons.

• Smell is a powerful memory trigger: Musty odors, the smell of river mud and stagnant water become tied to the hardest days. Each time you catch that smell, it can feel like being pulled back to the moment the water came in.
• Stains and mold you see every day: The waterline on the walls and the black spots of mold are constant reminders that the house is not quite safe yet. It becomes hard to feel that you have truly come home.
• Health worries: Parents and caregivers worry about children or older relatives coughing, sneezing or getting rashes. They worry about leptospirosis, diarrhea from contaminated surfaces, skin infections, and allergies or asthma flaring up because of mold spores. These worries quietly drain energy every single day.
• Work that never seems to end: You scrub, and scrub again, and the smell is still there. The feeling that "no matter how much I do, nothing gets better" is exhausting and discouraging.
• Money and time: Damaged belongings, days off work, unexpected expenses. Each on its own is manageable; together they become a heavy weight.
• Sleep that does not restore you: A damp, smelly bedroom makes it hard to sleep well. The less you sleep, the more fragile everything feels.

For households where someone is already looking after their mental health, for example a person being treated for depression, an anxiety disorder or another psychiatric condition, a sudden change to the home and daily routine can make symptoms harder to manage. The most important thing is to keep taking medication as prescribed and keep medical appointments. If medication was lost or soaked in the flood, contact the hospital or clinic that provides treatment as soon as possible. The house is a secondary concern, and it is something other people can help with.

It is also worth remembering that caregivers feel the strain too. The person who organizes the clean-up, talks to relatives, deals with repairs and keeps everyone calm is often the one who forgets to rest. If that is you, please include yourself in the list of people who need looking after.

Signs Worth Paying Attention To, and When to Call 1323

You do not need to be an expert to notice how the people you love are doing. Try asking gently, "How have you been feeling lately?" and really listen to the answer. Signs worth paying attention to include:

• Trouble sleeping, or waking up again and again, for several weeks in a row
• Losing interest in food, not wanting to see anyone, withdrawing more than usual
• Irritability and frequent arguments at home, when this was not normal before
• Replaying the flood over and over, or feeling panicky whenever it rains
• Feeling hopeless, that nothing matters, or wishing to disappear

If you notice these signs, especially the last one, please call the mental health hotline 1323 at any hour, or talk to staff at your nearest hospital. You do not need to wait until things are "serious enough." Wanting someone to listen is reason enough to call. For more information on staying healthy after a disaster, see the Department of Health, the Department of Disease Control, and the WHO fact sheet on floods and health, which also notes that floods can affect mental wellbeing.

Why Common DIY Fixes Often Don't Bring Peace of Mind

Most families do their very best with what they have. These are the methods we see most often, and why they frequently leave people feeling that the job is never finished.

• Scrubbing with bleach alone: Bleach can make the surface of a wall look clean, but it does not soak deep into concrete, plaster, wood or fabric, so mold can come back from below. The strong chlorine smell can also sting the nose and cause headaches, which is the opposite of relaxing, especially for someone who is already sensitive to smells.
• Running fans all day: Fans do help surfaces dry faster, which is good. But on their own they also blow mold spores around the house and into bedrooms.
• Air fresheners and scented candles: These mask the smell for a short time. The mix of perfume and musty odor can actually cause dizziness and make the house feel even less like home.
• Painting over the stains right away: Paint applied to a wall that is still damp will bubble and peel, and mold underneath often reappears as black spots within weeks. The second disappointment can hit harder than the first.
• Doing everything alone: Many people try to carry the whole clean-up on their own shoulders until their body and mind run out of energy, even though some of the hardest steps can be handed over to professionals.

How a Clean Home Can Help the Mind Recover

A clean house is not a treatment for stress. But it can become a safe place where the body can rest and the mind can slowly find its footing again. When the musty smell is gone, the mold has been dealt with and the bedroom is pleasant to breathe in, many families tell us they start sleeping better and feel ready to live normally in their home again.

• Fewer triggers: When the smells linked to the flood disappear, the mind is pulled back to that night less often.
• A sense of control returns: Watching the house improve step by step, with a clear plan, helps people feel that life is back in their own hands.
• Less worry about germs: Knowing that the surfaces touched by floodwater have been professionally disinfected lightens the constant worry about children and older relatives.
• Time back for the family: Instead of scrubbing walls every evening, there is time to sit down for dinner, talk, and simply rest together.
• Better sleep: A bedroom free of damp odor and airborne spores is simply a more comfortable place to sleep, and sleep is the foundation of every other kind of recovery.

The Solution: Chemgene HLD4H Disinfection and Ozone Treatment, at a Pace That Respects the People at Home

World Health Disinfection (WHD) provides a professional disinfection fogging service using CHEMGENE HLD4H disinfectant applied through ULV equipment. The very fine mist reaches corners, the space under beds, the back of wardrobes and other surfaces that a cloth and bucket simply cannot reach. This is combined with our ozone shock treatment service, which helps deal with airborne mold spores and breaks down the odor molecules trapped in curtains, mattresses, sofas and wooden furniture.

For homes where someone is feeling stressed, or where a family member needs extra calm and predictability, the team can adapt the way it works. We can agree on a convenient time, explain every step in advance, work without rushing, keep noise and movement to a minimum where possible, and answer the same question as many times as needed. Nobody should feel that strangers have taken over their home.

Our Step-by-Step Process

1. Listen and survey: We start by listening to the story of the house, then inspect where the water came in, where mold has appeared, and which rooms matter most to the people living there, such as an older parent's bedroom or a prayer corner.
2. Clean-up advice: We help you decide what should be thrown away and what can be kept, which takes some heavy decisions off your shoulders. Items with sentimental value are set aside to be cleaned carefully rather than discarded in a hurry.
3. Disinfection fogging: Chemgene HLD4H is applied by ULV fogging across all flood-affected areas, including floors, the lower parts of walls, door frames, skirting and furniture.
4. Ozone shock treatment: Rooms are closed and treated with ozone at a level suited to their size and the strength of the odor, to tackle mold spores and stubborn musty smells.
5. Ventilation: Doors and windows are opened and the space is aired out thoroughly before anyone returns.
6. Re-check and aftercare advice: We check the smell and the high-risk spots again, then explain how to control moisture over the following days and weeks so that mold has less chance of returning.

Caring for Yourself While You Care for the House: Small Things You Can Do Every Day

These are simple, everyday ideas, not clinical advice. Take what helps and leave the rest.

• Break the work into small pieces: One room today is enough. The whole house does not have to be finished in a day.
• Start with the bedroom: The room where you rest should be put right first, because good sleep supports everything else.
• Let older relatives help in gentle ways: Choosing what to keep, folding clean clothes or sorting photographs, rather than lifting heavy furniture, helps them feel useful and in control.
• Keep familiar routines: Eat at the usual times, go to bed at the usual hour, keep up prayers, merit-making or an evening walk. Familiar rhythms help settle the mind.
• Limit flood news: Checking the essential updates once or twice a day is usually enough. Watching the news all day keeps the body on high alert.
• Talk to each other: No one has to be strong all the time. It is fine to say "I'm tired" and to thank each other for the small things.
• Drink water and eat regular meals: It sounds obvious, but in the middle of a clean-up many people skip meals and forget to drink, which makes tiredness and irritability worse.
• Ask for help: For the house, from neighbors, relatives or a professional team; for the heart, from the 1323 hotline or your local hospital.

Before and After

A Customer's Voice (Example Scenario)

"At first I thought it was only about the smell. But once the house stopped smelling, Mum agreed to sleep in her own room again. That night we both slept properly for the first time in weeks. The team explained everything slowly, and when Mum asked the same question several times, they answered every time. For the emotional side, we also called 1323 and talked things through. It felt like we weren't fighting this alone anymore."

Frequently Asked Questions

Q: Will the stress go away once the house is clean?
A: A clean home reduces triggers and makes it easier to rest, but it is not a treatment. If you still feel overwhelmed, cannot sleep for weeks, or feel hopeless, please call the 1323 mental health hotline or see a doctor.

Q: Someone in our home is receiving psychiatric treatment. How should we prepare before the team arrives?
A: Let the team know in advance if you would like them to work quietly or explain each step first; we can adapt. Plan for the person to have a familiar place to stay during the ozone treatment, and keep up with medication and appointments as usual.

Q: How long do we need to stay out during ozone treatment?
A: It depends on the size of the area and how strong the odor is. No people, pets or plants may be in the room while ozone is running. The team will tell you when it is safe to return after ventilation, and the work can be done one zone at a time.

Q: Does Chemgene HLD4H have a strong smell?
A: It does not have the sharp smell of chlorine bleach, so it suits households where people are sensitive to odors. You should still ventilate as the team advises.

Q: What about precious items such as photographs, letters or amulets?
A: Set them aside first and do not rush to throw them away on a day when you are not ready. Wet photos and papers should be air-dried in the shade with good airflow. Delicate valuables will be moved out or covered during ozone treatment.

Q: Can we do part of it ourselves?
A: Yes. Small, frequently touched spots such as door handles, tables and bathroom fittings can be treated with Chemgene HLD4H spray. Areas that were soaked for a long time or where mold has spread are better handled by professionals.

Q: Which areas do you serve?
A: Pak Kret, Mueang Nonthaburi, Bang Bua Thong, Bang Yai, Bang Kruai, Sai Noi and nearby areas across Bangkok and its surrounding provinces.
