Flooding in Asia: Impacts on Tourism and How to Protect Your Health During Natural Disasters

Asia has long been one of the most popular destinations for year-end travel. Its unique tropical climate, stunning coastlines in Southeast Asia, charming historic cities in East Asia, and cool mountain landscapes in the northern region attract millions of travelers during the winter season. For many, this period is considered the perfect time to explore the diversity and natural beauty the continent has to offer.

However, despite being the winter season, several countries across East Asia have recently faced extreme weather conditions. Heavy rainfall has been reported in many areas over the past week, leading to widespread flooding in countries such as Thailand, Malaysia, and Vietnam—destinations that typically welcome a high number of tourists toward the end of the year.

Flooding : More Than Just Physical Damage

The impact of flooding often extends far beyond damaged homes, roads, and property. In many cases, families are forced to evacuate with little to no preparation, while some are unable to leave their homes in time. As people gather in evacuation centers or temporary shelters, the risk of illness increases significantly—especially when living conditions become crowded and humid.

Common flood-related illnesses include:

  • Respiratory infections caused by damp environments
  • Colds, nasal congestion, and a runny nose
  • Skin infections from contaminated water
  • Gastrointestinal diseases such as cholera and diarrhea

 

How to Stay Healthy During Flooding and Humid Conditions

Protecting your health is crucial during a flood. Here are some simple but effective ways to reduce your risk of illness:

1. Stay Dry and Avoid Prolonged Dampness

Humidity encourages the growth and spread of bacteria and viruses. Change into dry clothes as soon as possible if you get wet, and avoid sitting or standing on damp surfaces for long periods.

2. Wear a Mask in Crowded Areas

Evacuation centers and shared shelters can become hotspots for respiratory infections. Wearing a mask helps reduce the risk of spreading or catching common colds and viral illnesses.

3. Relieve Cold Symptoms and Breathe More Comfortably

Flooding often brings stale and humid air, which can worsen nasal congestion and make breathing uncomfortable. Aromatic natural remedies—such as essential oil–based inhalers or stickers—can help provide relief without strong medication.

 

For instance, Happy Noz Original Formula contains extract from a special variety of red onion oil, which helps relieve cold symptoms, nasal congestion, runny nose, and wheezing. Suitable for those with clear nasal discharge.

4. Strengthen Your Immune System

A strong immune system helps the body fight infections more effectively. Maintain a balanced diet, get enough rest, and manage stress as much as possible.

Some people also choose Happy Noz Anti-Virus Formula, which contains turmeric essential oil rich in antioxidants, which can help promote overall immunity—useful during unpredictable weather.

 

5. Avoid Direct Contact With Floodwater

Floodwater is often contaminated. Avoid walking through it unless necessary. If you must, wear protective footwear and wash thoroughly afterward using clean water.

Asia remains one of the most attractive regions for year-end travel, but unpredictable weather patterns have made flooding an increasingly important issue to monitor. Beyond disrupting travel plans, floods pose significant health risks for residents and visitors alike. Being well-prepared, taking proper care of your health, and using natural remedies when needed can help you stay safe and resilient during challenging weather conditions.
