How to stay healthy in Vietnam's humid weather

Stay hydrated with electrolyte drinks, wear breathable cotton or linen clothing, and take breaks in air-conditioned spaces every 2-3 hours. Carry oral rehydration salts and shower twice daily to prevent heat rash and fungal infections.

Pack the right clothing. Bring loose-fitting cotton or linen shirts, breathable underwear, and moisture-wicking socks. Pack 2-3 extra changes of clothes per day since you'll sweat through everything. Avoid synthetic fabrics except for quick-dry travel pants.
Manage your hydration strategy. Drink 3-4 liters of water daily, but add oral rehydration salts (ORS) to 1-2 bottles to replace electrolytes. Vietnamese pharmacies sell ORS packets for 5,000-10,000 VND each. Drink before you feel thirsty.
Plan around the heat. Schedule outdoor activities before 10am and after 4pm. Use the 11am-3pm window for indoor attractions, malls, or cafes with air conditioning. Take a midday break at your accommodation to shower and rest.
Prevent skin problems. Shower twice daily with antifungal soap to prevent heat rash and fungal infections. Dry thoroughly, especially between toes and in skin folds. Apply talcum powder to feet and groin area before getting dressed.
Recognize heat exhaustion signs. Watch for headaches, dizziness, nausea, or fatigue. If you experience these, immediately move to air conditioning, drink ORS solution, and rest for 30-60 minutes. Seek medical help if symptoms worsen.
