Humans spend about one-third of our lives sleeping, and although many of us have a very good understanding of this, scientists are still looking at a lot about sleep. They are looking at why humans and other animals need to sleep and also think about sleeping trees at night. Sleeping trees at night is a fact, trees can get an afternoon nap at night.
It is known that most living organisms can adjust their behavior to the rhythm of night and day. Now, using laser and scanners, many scientists study the rhythm of night and day on trees, and it turns out that sleeping trees at night is also real.
Many people wonder whether sleeping trees at night comes after a long day. Scientists say it depends on how they define "sleep." They say that trees relax and their branches at night, which may be a sign of snoozing.
In the only study published on sleep trees at night, researchers explained that they used lasers to measure the movements of two silver birch trees at night, one in Finland and the other in Austria, which were observed from dusk until a dry morning , Laser scanners used infrared light to illuminate different parts of the tree, and the researchers said that these details were sufficient to set each tree within minutes.
They surprised the researchers when they found that the branches of the birch tree began to slow down at night. They also noticed that it was slowly returning to its place a few hours before sunrise and then again in the early hours of the next morning.
It is clear that the researchers have relied on the rhythm of their internal biological clock, but they have ruled out the fact that some branches that return to place during the day already before the sunrise may be doing so according to the hour of the internal daily.
The researchers said that these results were a bit surprising, but it is strange that it has not been studied so far, most organisms have a day and night rhythms every day, and also trees, any gardener notes that some plants bloom in the morning and some trees close their trees at night It is called sleeping trees at night.
The phenomenon of sleeping trees in the night was also studied in plants when the famous botanist Carl Linius found that the flowers are confined in a dark cellar and are still opening and closing. The naturalist Charles Darwin also noted that the night movement of plant leaves and stems resembles sleep.
However, their studies focused on small plants grown in pots, so the researchers' findings on trees were the first study of laser use to accurately measure the night movements of many wild trees.
