Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Curiosity.com.

I'm Cody Goff.

And I'm Ashley Hamer.

Today we'll answer a listener question about why things sound louder in the morning.

Then you'll learn about a trick to stay motivated

from physicist and entrepreneur Safiva Call.

You'll also learn about the science of the winter solstice.

Let's satisfy some curiosity.

We got a listener question from Kendra who writes,

During the school year, I'm up before everyone else in the house to get ready.

Okay, so first off light waves don't affect waves, so we can cross light right off the list.

But what about temperature? This one is possible.

Sound does carry farther in cold weather.

Basically, when a sound wave in the cold hits a pocket of warm air

higher in the atmosphere, it bends and comes back down to the ground,

which carries it farther.
