The short answer
Kathmandu's dry-season air can be dusty and polluted, and traffic adds smoke. A fitted mask, a hotel away from main roads, and fewer hours in heavy traffic help. At altitude and on clear days the sun is strong; the UV is higher than at sea level, so wear sunglasses, a hat and high-factor sun cream, and reapply it.
Lip balm with sun protection, a neck cover and light long sleeves reduce burns. Drink enough water to offset dryness.

City air and dust
Kathmandu can be dusty and smoky, especially in dry months and on busy roads. A fitted mask, glasses and a hotel away from main traffic can make a difference. Rest in cleaner places, such as gardens, when you can.
People with breathing problems should plan extra care and carry their medicines. Rain often clears the air for a while.
Sun at altitude
The sun is strong at altitude, even when it feels cool. Wear sunglasses with good protection, a hat, sun cream and lip balm. Cover your neck and the backs of your hands.
Drink more water than you think you need, since dry air and sun increase dehydration. Reapply sun cream often, especially on snow or light surfaces.
Insider tip
Pick a hotel on a side street or with a garden.
Avoid this
Do not rely on cloud cover to prevent sunburn at altitude.
