From the brains behind brains on, this is the Moment of Um.

Moment of Um comes to you from APM Studios. I'm Janet Jaguar.

Um... You've caught me at the perfect time. I'm riding my bike home from the office.

As I'm sure you know, I'm a high-powered business cat working in New York City.

I design advertisements for some of the top brands in the world,

Perizon, Kitty Bank, and of course, PetFlix. My job is extraordinarily stressful, or at least it

used to be. I realize life is too short to spend all my time thinking about work.

That's why I'm doing more of the things I love, like riding my bike.

Out of my way, extremely relaxed cat coming through.

And when I get home, I like to make myself a cup of piping hot tea. Mint, ginger, green

tea, I love them all. Some of my human friends like chamomile tea, too. It's made from the flowers

of the chamomile plant, and I've heard it makes them feel all warm and sleepy. Mm, sounds nice.

I wonder why chamomile tea makes humans feel tired.

Greta and I both want to know.

What part of the chamomile plant makes you feel sleepy?

Camamil is a common tea that people drink, and people often ask, what is it in chamomile that makes us sleepy?

My name's Chris Winter, and I'm a neurologist or brain doctor and sleep specialist.

There are a variety of chemicals in chamomile that tend to relax or make us feel sleepy.

There's a chemical called a pigeonon that is most likely to create that effect.

It has an effect like certain drugs that people use to make them feel sleepy.

There's a chemical on our brain called GABA that this chemical interacts with to make us feel sleepy.

Also, just the warmth of the tea at night can sometimes have an effect on people's sleep.
