It’s fairly common knowledge that the London Underground isn’t the cleanest or most pollution-free place in the world – or that these things aren’t great for our skin.
However, not all tube lines were created equal in this regard.
The experts at SpaSeekers have looked at a range of factors to try to determine which underground lines are the worst for our skin.
To do this, they measured things like the presence of bacteria, pollution levels, carriage temperature, humidity, the length of the line and the number of weekly riders.
According to their findings, the Northern line comes claims the top spot for being bad for our skin.
The line exposes riders to pollution levels a whopping six times above the World Health Organisation limit, has what the research describes as ‘high’ levels of both bacteria and PM2.5 (the air pollutant thought to have the biggest impact on our health) and transports 1.1 million riders each week.
The Victoria line comes in second place, with 955,000 weekly users also coming into contact with high levels of bacteria and PM2.5.
In third place? The Piccadilly line, which is one of the hottest tube lines of them all with no air-con to its name adding sweat and dehydration to the mix along with its high bacteria levels.
As for the tube line that will have the least impact on your skin, that’s Hammersmith & City, thanks to its low bacteria and PM2.5 levels, shortness and comparatively small number (231,000) of weekly riders.
If you have to travel on the tube lines or any other type of public transport for that matter, it’s best to try and touch as little of your surroundings as possible and avoid touching your face, because your hands can help bacteria spread from surfaces to your face.
The SpaSeekers team also recommends washing your hands after your commute, staying hydrated and double cleansing when you get home to get your skin as clean as possible after the tough day it’s had.
