On cold winter days, having a foot warmer really helps.

We were saved from the threat of infectious diseases thanks to the vaccine.

I like to ski in winter.

It's very cold today, isn't it?

On cold days, warm coffee is the best.

On a cold winter night, hot cocoa is the best.

The cold has become severe.

It's difficult to go outside in this coldness.

Winter is my favorite season.

Please bring out the winter clothes.
