There are many people in the room. They are in the museum.

The room temperature is higher than 0 degrees Celsius.

But there is a device under the ice that can keep the ice below 0℃

Athletes have been training and competing in such venues for a long time.

I'm used to this temperature (besides, physical work like brushing ice will make me sweat)

But on the whole,

It's still cold

Just look at the clothes in the audience.

Athletes will also put on their coats to keep warm immediately after the game.
