DOES THE TREES SLEEP AT NIGHT LIKE US?
How do they do it and why do they sleep? Do they have to rebuild like us, do they have thoughts other than ours, do they dream?
A study reveals how the trees sleep at night and I want to share it with you.

Although they do not snore or dream like humans and other animals do, trees also “sleep” at night. This is confirmed by a fascinating study carried out by a team of scientists from Austria, Finland and Hungary.
Nature has many wonders to teach us: Trees also sleep at night, according to research by scientists from Austria, Finland and Hungary. The purpose of the study was to find out if the trees followed day and night cycles similar to those observed in small plants.
To demonstrate this, they used laser scanners targeting two birches. Scientists recorded physical changes indicative of a night's sleep, with the tips of the birch branches dropping up to 4 inches toward the end of the night. Musician translates tree rings into music for record player
"Our results show that the entire tree falls overnight, which can be seen as a change of position in the leaves and branches," said Eetu Puttonen of the Finnish Geospatial Research Institute in a statement. "The changes are not too big, only up to 10 cm for trees with a height of about 5 meters, but they were systematic and within the precision of our instruments."
In an article published this month in Frontiers in Plant Science, the scientists explained how they scanned two trees, one in Finland and one in Austria. Both trees were scanned independently, on calm nights and around the solar equinox to ensure a similar duration of the night. The results showed that the branches of the tree fell lower just before dawn, while they returned to their original position in just a few hours.

The researchers believe that the drop effect is caused by a decrease in the tree's internal water pressure, a phenomenon known as turgor pressure. Since photosynthesis, responsible for driving the conversion of sunlight into simple sugars, is not performed at night, trees likely conserve energy by relaxing branches that would otherwise be angled toward the sun.

"It was a very clear effect and applied to the entire tree," András Zlinszky, from the Center for Ecological Research in Tihany, Hungary, told New Scientist. "No one has seen this effect before on the whole tree scale, and I was surprised by the magnitude of the changes." The following plans involve applying lasers to other forest species to see if they also exhibit a circadian rhythm.
