This is actually true though, when I was in the Army we were always told to be careful during cold weather deployments due to this and if you had surgery within 72 hours you skipped the cold weather drop.
In 1984 they dropped my group deep in Alaska backwood during early Spring, we were at a pretty low altitude and had to hike 40 miles through primal territory to get to the pickup location in two days, but the path went right over a mountain range and altitude went up something like 2000 feet then back down if I recall. At the crest of the mountain the temperature was around 10 degrees.
We were working over the top and there was no snow falling but there was some on the ground, it was a slog for sure. We were all under 25 - I was the oldest one and the least athletic of them all. Janey, this wirey dude who was super smart and was a long distance cyclist, collapsed suddenly and we had to radio in and hike him to an emergency pickup spot. He ended up dying on the helicopter ride to our home base and it turned out to be a blood clot from the cold - he weighed 120lbs tops, 22 years old, and was healthy as a horse.
More Babylon Bee type headlines coming to pass. The tragic comedy continues. As The Clown World Turns.

Wow, they say that if your house is colder than 18C (64.4F), your blood will get cold and thicken and you'll be at risk of blood clots.
"It adds that when we start to get cold, our blood becomes thicker, which can lead to blood clotting - this is when it clumps together and hardens."
They must think their audience is a bunch of ignorant children. They likely are correct.

Yes. But this is not some critical issue when your house is 65 degrees inside and you're wearing a sweater.
