How to Chimney Effect Keeps Me Cool


HTMC 38 - How the Chimney Effect Keeps Me Cool.001


As you may know, I was born and raised in the mountain town of Lillehammer, Norway.

The local people joke that because the terrain is so steep, they always have to walk uphill to get anywhere.

Now, a hill never stopped me; I love to exercise. But one thing that always bugged me is that I got sweaty.

Especially when it was cold and I was wearing a winter jacket.

The thing is, I usually wore my jacket closed, using both the zipper and the press studs.

How the Chimney Effect Keeps Me Cool

When I was in the Royal Norwegian Navy, I learned two ways to keep sweat-free and ventilated while wearing a jacket:

  • Wearing it open
  • Closing the press studs, but not the zipper

The thing is, as soon as you close the zipper, your jacket becomes almost airtight, which means it doesn’t breathe.

Heat and moisture build up inside your jacket, making you feel sweaty.

When you close your jacket with the press studs only, the warm, humid air can escape between the gaps.

Just as hot smoke from a fireplace rises up through a chimney …

… the hot air under your jacket floats outwards between the press studs and is replaced with dry, cool air that’s sucked in from underneath your jacket.

Now, if you don’t have a jacket with press studs, I highly recommend that you get one.

That way, you can benefit from the chimney effect when you’re active in the winter.

Just be sure you know which colour jacket to buy before you spend your hard-earned money.
