Cambodia has real, often seasonal or localized pollution worth knowing about, especially if you have asthma or allergies.
Not typically needed for most travelers, but if you have asthma or allergies, it's a cheap, compact backup worth packing regardless of destination.
This reflects typical/baseline conditions, not a live reading — actual air quality varies day to day with weather, season, and wildfire or burning activity. If you have asthma, allergies, or another respiratory condition, check a real-time index (like IQAir or AirVisual) for your specific destination before travel, and pack a mask if the level is elevated.
Hospital bills abroad are the single most expensive travel surprise — and exactly the kind of risk pages like this one can't protect you from. For trips to Cambodia, a travel medical plan like SafetyWing Nomad Insurance covers new illnesses and injuries, hospital stays, emergency evacuation and lost luggage across 180+ countries, works on a flexible 4-week subscription, and can even be bought after you've already left home.
