Today’s Wonder of the Day was inspired by Kathryn from jasper, IN. Kathryn Wonders, “How does your body know if you are taking a nap or going to bed?” Thanks for WONDERing with us, Kathryn!

Yaaaaawwwwnnnn. Do you ever feel drowsy in the afternoon? After a big lunch, it can be hard to focus at school or work. That's why many people take afternoon naps.

Wait, aren't naps for babies? Yes, naptime is an important part of a baby's day. However, naps also help some kids and adults. Naps make them feel more alert and productive. Many adults find a quick nap is as helpful as a cup of coffee!

Afternoon naps are traditional in some countries. In Spain, they call them siestas. Many Spanish businesses close midday so people can nap. However, not all countries are as approving of naps. Many in the United States see napping as a sign of laziness. With so many opinions floating around, it's difficult to decide what to think!

Are naps good for us? Sleep studies have found both pros and cons of napping. NASA studied what happened to astronauts who took naps. They found that naps helped them stay more alert and get more work done. After a nap, the astronauts also had better mood, memory, and creativity.

Are you thinking about taking a nap? There are a few steps you can take to get the most benefit from a nap.

First, experts say the best naps last 20-30 minutes. That means you should set an alarm for your nap and get up when it goes off. No pressing "snooze"! Long naps can cause sleepiness for the rest of the day.

Second, take your nap right after lunch. Naps later in the day will make you sleep less deeply that night. Most experts say you should nap between noon and 4 p.m.

Finally, find the right place for your nap. The ideal spot is quiet and a little chilly. Nap in a dark room where others won't interrupt your sleep.

Napping has gained popularity over the last few years. Are you ready to join the ranks of nappers? You'd be in good company! Winston Churchill, Eleanor Roosevelt, and Albert Einstein are just a few famous people known to nap. In fact, 85% of mammals nap throughout the day!

Still, napping isn't for everyone. Some wake from their naps with more energy. Others don't seem to get any napping benefits. To decide whether naps are for you, pay attention to how you feel throughout the day. Do you feel drowsy after lunch? Are you more or less alert in the afternoon? The only person who knows whether you need a few ZZZs is you!
