PYEONGCHANG, South Korea — The Americans are wearing battery-powered parkas, while the Canadians are using heated snow pants. The Norwegians brought their own hot chocolate.

Then there’s the scene at the moguls skiing hill, where yoga mats — or things that look like yoga mats — are used to create a barrier between one’s feet and the freezing turf.

The conditions here are severe. The men’s downhill ski racing event, scheduled for Sunday, was postponed to Thursday because of strong winds and the unfavorable forecast. Some training sessions scheduled for Monday were canceled.

So at this unusually chilly Winter Olympic Games — with wind chills expected to make it feel below 0 degrees Fahrenheit (minus 18 Celsius) — elite athletes long accustomed to cold weather are trying anything and everything to stay warm.
