Pollution in January?

Question

A group of friends are planning to travel in January, visiting major cities like Beijing/Shanghai/Chengdu/etc. I'm concerned about air pollution as I heard it is worse in winter. Can anyone confirm? One friend has weak lungs so I'd rather we not go and end up in a hospital.

Answer

Air pollution in China can indeed be worse during the winter months, particularly in northern cities like Beijing. Cold weather, increased heating demands, and less wind can cause smog and higher particulate matter levels. Southern cities such as Shanghai and Chengdu typically experience better air quality than northern cities in winter, but pollution can still be moderate at times.

Health considerations are especially important if one of your friends has weak lungs or respiratory issues. Exposure to high pollution levels can exacerbate asthma, bronchitis, or other respiratory conditions.

Key points to note about winter air pollution in major Chinese cities:

Beijing: Often experiences higher PM2.5 levels in January due to heating emissions and stagnant air. Days with heavy smog are common, though government measures have improved air quality over the years.
Shanghai: Pollution is generally lower than Beijing, but winter haze can still occur. PM2.5 levels may be moderate.
Chengdu: Winter air can be damp and sometimes foggy. Pollution tends to be moderate, though it can fluctuate depending on weather patterns.

Precautionary measures:

Monitor daily air quality forecasts for each city. Apps and websites provide real-time AQI (Air Quality Index) readings.
Bring or purchase N95 or KN95 masks for outdoor activities, especially in Beijing.
Limit outdoor exposure on days with high pollution readings.
Consider staying in well-ventilated accommodations with air purifiers.

Alternative strategies:

If your friend’s health is a major concern, consider visiting southern cities like Guangzhou, Shenzhen, or Hainan in winter, where air quality is generally better and temperatures are milder.
Plan indoor activities for days when air quality is poor.

In summary, January can pose air pollution risks, particularly in northern cities like Beijing. For someone with weak lungs, it is crucial to monitor air quality, use protective measures, and possibly adjust the itinerary to prioritize cities with better winter air conditions.
