People often ask us why we always wear masks, well at the moment we are in one of the most polluted parts of Vietnam, Hanoi being the worst with an AQI (air quality index) of 211 which is very harmful, although this is an improvement on recent months, notice how London scores 27 which is good, even if you think London is polluted.
In Vietnam, around 60,000 deaths each year are air pollution-related, in the UK this figure is 28,000.
It’s not only the general air pollution, but also the dust and exhaust fumes from old vehicles that makes cycling these busy polluted roads more difficult due to difficulties breathing, this is then magnified in the heat.
