Do Trees Sleep At Night?

You're not the only one who gets shut-eye at night. Turns out trees do a little snoozing, too.

If A Tree Sleeps In The Forest...

Can you picture a napping tree? It sounds silly, but for the first time, researchers have observed trees "sleeping" in what appears to be a nighttime ritual. The study, published in February of 2016, noted that the trees dropped their branches down as far as 3.9 inches (10 centimeters) at night, and they began to rise again just before the sun came back up. The changes weren't huge but they were systematic, and suggest that trees have their own circadian rhythm. It's unknown whether or not these movements are active or passive, but the researchers believe the findings may help related industries, like timber and rubber, understand more about a tree's internal water cycles.

That's Cute, But Why Should I Care?

It's easy to take the world around us for granted, but there's so much we can learn from nature—even the world right outside your window.
