Less Oxygen in cold weather

[Beemocat1]

I read years ago that when the air is below freezing it’s harder for the O2 to be absorbed by the lungs- hence why very cold runs feel harder.

Fact or fiction?

I did W2D1 in -3 today- it was horrible and my face hurt it was so cold 😥😄

I think it's something to do with the body using energy to stay warm instead of letting you use it for running.

Air is actually "thicker" or more dense when it's cold so theoretically you're getting more oxygen per lung full, not less.

Yes I didn’t even sweat so that would make sense- it felt as hard as my very first run. Interesting!

Get a Buff... they are brilliant..keep out the cold and the rain and the snow... I love mine.. and as I get horrible pain when my face gets cold, find it invaluable! Lots of places sell then.. and online too.. Amazon do

I have always thought as IainlW, above. Certainly works that way in an internal combustion engine, giving more oxygen for a given volume.

Cold air constricts bronchial tubes, so may make it more difficult to breathe, and can trigger asthma in those who are susceptible. Oldfloss's suggestion of a buff, is the way I go, whenever the temperature drops. There are cheaper, and perfectly good, alternatives to the rather pricey original buff.

Well done on your run.
