Trees Have a “Heartbeat,” Scientists Discover

‍‌Researchers discover trees have a “heartbeat,” it’s just so slow we’ve never noticed before

Until now, scientists thought water moved through trees by osmosis, in a somewhat continuous manner.

Now they’ve discovered the trunks and branches of trees are actually contracting and expanding to “pump” water up from the roots to the leaves, similar to the way our heart pumps blood through our bodies.

The only difference between our pulse and a tree’s is a tree’s is much slower, “beating” once every two hours or so, and instead of regulating blood pressure, the heartbeat of a tree, regulates water pressure.

“We’ve discovered that most trees have regular periodic changes in shape, synchronized across the whole plant … which imply periodic changes in water pressure,” András Zlinszky of Aarhus University in the Netherlands told New Scientist.

In his 2017 study, Zlinszky and his colleague Anders Barfod used terrestrial laser scanning to monitor 22 tree species to see how the shape of their canopies changed.

The measurements were taken in greenhouses at night to rule out sun and wind as factors in the trees’ movements.

In several of the trees, branches moved up and down by about a centimeter or so every couple of hours.

After studying the nocturnal tree activity, the researchers came up with a theory about what the movement means. They believe the motion is an indication that trees are pumping water up from their roots. It is, in essence, a type of “heartbeat.”

Zlinszky and Barfod explain their theory in their newest study in the journal Plant Signaling and Behavior.

“In classical plant physiology, most transport processes are explained as constant flows with negligible fluctuation in time,” Zlinszky told New Scientist. “No fluctuations with periods shorter than 24 hours are assumed or explained by current models.”

But the researchers still don’t fully understand how the “pumping” motion works. They suggest maybe the trunk gently squeezes the water, pushing it upwards through the xylem, a system of tissue in the trunk whose main job is to transport water and nutrients from roots to shoots and leaves.

In 2016, Zlinszky and his team released another study demonstrating that birch trees “go to sleep” at night.

The researchers believe the dropping of birch branches before dawn is caused by a decrease in the tree’s internal water pressure. With no photosynthesis at night to drive the conversion of sunlight into simple sugars, trees likely conserve energy by relaxing branches that would otherwise be angled towards the sun.

These birch movements are circadian, following the day-night cycle.

Their new discovery is something entirely different, they say, because the movements happen at much shorter intervals.

    I have heard trees drinking after a drought, not just one tree but a whole city block of trees. The sound and volume was quite surprising.

      My understanding of divine creation is that God is in the trees. Trees (soul) are on the gross plane, after stone. Stone moves very slowly and plants, attached to the earth, move faster, up the planes to worm…who is able to crawl rather than being attached, like trees and plants. In the elemental kingdom of trees, evolution gives life to God’s creation. Worm turns into honeybee, and it is the first stage of leaving the earth and going airborne. Honeybees (and pollinators) are the first to express pure Love in creation. They do what they do in unison with the hive and the Love permeates survival of the whole. Love is what goes on the the hive in order for all bees to survive. Same with all pollinators…they create life out of pure love.

        Beekeeper here, I take it you have not studied or worked closely with bees. They raid other waker hives, they sometimes kill queens they feel are not performing well, they produce far more drones than are needed which are then forced out to starve or freeze in the fall air, a new queen kills the old queen, so on and so forth. They are decidedly not focused on love. They are analytical, opportunistic, and efficient.

          I spontaneously applauded you for this actualised answer tearing apart this romantic rigmarole of the lovey-dovey bee…
          Then again, I would find it interesting to give it a second thought. How sure can we be about the absence of “love” in a bee? We might need to alter and adapt our human definitions of love (ranging from grace of charity, altruism to desire etc.) a little in a more biologistic, less Christian way.
          What may love be for a bee?
          Can she feel desire?
          Could killing a useless male or royal possibly be an act of love? Just wondering…

          1. Kent Paul Dolan Avatar

            It helps in positing emotions for a bee to conceptualize the colony as the individual and the bee as a sub-entity of the hive. Then the evolved behaviors of the hive, such as efficiently replacing queens, can be mapped onto human concepts like self-love.

            For what it is worth.

      Was this in SoCal?
      After the 5 year drought in Sta Barbara, when the rain came, you could hear the ground sigh as the moisture permeated the clay, and feel the plants breathe, the roots expand as they drank up the water. It went on for a full year as gentle rains soaked in. In time the leaves and branches stopped drooping, the full color was restored to the bark, the fiber swelled. The sound was visceral and rather subsonic, but when you walked the back country away from cars it was a burbling stream quietly running upwards.

    so many trees are dying?.. just cut? .. what a shame, if that is a case, plant another forest nearby.. wtf

    1. PGTips Avatar

      There’s a saying, from little acorns do large oak trees grow. A forest takes decades of tree growth, there will be no trees left if they are all cut down & replaced with younger ones. The planet will become a giant tree nursery,young trees in a baking hot climate & little oxygen left for us humans ect. Big trees, more oxygen for us less harmfull gasses. Think of it like saying, every kid that reaches a certain age is too old so has to be killed. Where do the next adults come from? Just saying.

      1. Diane Avatar

        Trees are lungs of the Earth, once they are gone, the Earth, and everything on it will cease to exist. Trees make the oxygen we all need to live.

        1. Mike Avatar

          Diane, though trees very much help regulate climate and water in local areas, they do contribute to our local air quality, but do not be mistaken that the majority of the oxygen that we breathe on this earth comes from phytoplankton photosynthesis…in our oceans!

    2. Christina Avatar

      Towns in Connecticut prefer to remove trees because of the taxable income from golf courses & shopping centers. Homeowners remove trees because they don’t want to take leaves in the Autumn. Trees naturally cool houses not only because of the shade, but also because cooler air… next to hot air… creates a breeze. Once the tree is cut… the homeowner is compelled to buy a better A.C. system. Great.

      You cannot replace ancient trees or ancient woodland, it has taken over 400 years to achieve that level – new trees/woodland planted today will never achieve the same status as we no longer have the soil structure to create it…wtf

And Bonnie, I and many others agree with you completely — it’s just that that wave of understanding and experimentation came and went and now newer waves of approach have taken over. But I’ll always believe that those of us who were there and alert and healthy and ‘daring’ enough at the time will never forget how great it was. Thanks!

          So true! I didn’t do the drugs, but meditated and achieved altered states to “become” trees, animals and even stones. It was so very magical to experience life as a tree and to slow WAY down and feel what it felt like to be a stone. Everything is alive! They all have consciousness and think and communicate and have personalities! Wish I could still do that!

It’s in the bark.They’ll say I’m crazy, but 50 years from now, they’ll say the same thing and only they could know because after all a machine told them so.

        there is a study going on that implies that if children are not exposed to nature by age 9 or 10 (can’t remember) they really won’t ever have a connection to it.

      I have experienced this on regular basis after morning meditation, when i walk and sit under our maple trees. Early morning, when sun starts to fall, is on great time to observe this. they are a bit more animated, the subtle water noises are not linear, its a bit more animated. at some point, the synchronicity and correlation with other trees near by becomes apparent. to be honest they feel so alive, as in like sitting with a large friend … elephants or something…

      it is one of the joys of human life to discover, and i encourage everyone who have not tried it to do so. but one needs to be slow… their processes happen so slowly. even the tree song of rustling water movements … very slow for a human mind. cheers !

      There was a time when I was extremely depressed- could barely get out of bed to tend to work. But I had the impulse to walk in the woods, which helped some. And then one day on one of the walks, I had the urge to sit with my back against a large tree. So I did. I curled up at the bottom and put as much of myself against the trunk as I could. I was wrapped inside the tree’s energy. I could feel it. It was so much bigger and steadier than mine. And I had a few hopeful images that came to me while I was there. I got up from there a while later and felt good for the first time in s long while. I did that periodically until I got on an even keel again.

    If Humans chop bits off anything else with a ‘Heartbeat’ it is considered Grievous Bodily Harm and they can be imprisoned, so should trees now be treated differently and protected as a Living being?? Perhaps experiments should be done when trees are being chopped at to see if the Trees groan (as in pain) as then perhaps Trees would be considered Sentient and left alone…

    If you know how to use a pendulum, you can communicate with your plants. I used this method to gauge watering indoor plants. They seem to grow better when watered only when they are ready. Don’t forget to actually touch the plant with one hand and use the pendulum in the other.

Plants are almost always communicating – but our human ears can’t pick up their frequency. This machine “interprets” their song for our human ears. So wonderfully awesome!!

    I have just returned from Puerto Rico. The damage to the trees is heartbreaking, I could feel the pain and loss. I could also see the recovery by so many trees that were able to withstand the storm. There is a ceiba tree in Ponce whose roots extend approximately 15-20 minutes away, she is magnificent.

    Being a tree hugger this scientific breakthrough makes my heart sing! I’ve had the fortunate experience of hearing trees ‘talk’ – at first I thought people were hiding and whispering but there was nobody around. I couldn’t discern the muffled tree voices but they were really talkative, and I got the sense they were well aware I was eavesdropping which they seemed to be celebrating. Beautiful, life changing experience. My appreciation of trees has soared exponentially since… absolutely breaks my heart when people cut trees down!!!

      That reminds me of one of my experiences years ago when I was being a tree, and I was looking around me on both sides and seeing severed arms and legs up and down the street, and my pain was unbearable seeing my family and friends needlessly destroyed like this. Nobody can tell me that what the electric company does to remove all the branches that grow too close to the elec. lines doesn’t hurt the trees. How would you feel if you were one of those trees?

    BUT…..they say that the heart is NOT a pump! What of this?

    Why do so many people pay no attention to this?

    I grew up surrounded by trees. I played among them and later worked among them. Day and night I could hear them rustling with the wind or with the chatter of the creatures that live in them or among them. The forest was full of life of all sorts, and that life depended on the trees for shelter, concealment, oxygen, even food and water. We need to protect the trees, especially from the ravages that some of our own species inflicts upon them in the name of profit.

    Lived in a rented place last year and there were some flowering plants, neglected and on the verge of death. I watered them and soon they were healthy. One day as I was walking besides them I got a feeling as if I just drank water after feeling parched. There was no reason for me to feel that way because I was neither feeling thirsty nor was I drinking water. Then I realised it was those plants sending that feeling as Thank You to me. Changed the way I look at plants now not only did they recognised me they sent a Thank You too…

    Everyone who is interested in this should read the novel “The Overstory” by R. Powers. Amazing book about this very reality of the world of trees.

    Trees remind me of the spine going up to the brain.

    So beautiful.

    I think this research is fantastic and just let’s us know that we still have a lot to learn .I am a plants man and I live for plants and I am so excited by these revelations.I always believed that plants were like humans in so many ways.I would love to keep in touch and congratulations on your scientific discovery.

    Not only trees, all plants and life forms on the earth have their ‘heartbeat’… all life are living with universe rhythms. Therefore, herbal medicine is natural medicine. Albert Einstein said: ‘Future medicine will be the medicine of frequencies.’ …
    There is a Chinese saying: “Truthfully talking is from heart.’ Trees can talk with us and can cure our emotional disorders and pure our sprits… try to feel it..

    Trees are breathing creatures with skin, veins, circulation and nerves. You can feel pain and be happy, have paranormal abilities and soothing healing powers. You can communicate with humans, heal your soul and body, change your character, and give comfort.

    We are living in a condo in Portland, Oregon that looks directly into Washington Park, the gateway to Forest Park and over 26 miles of hiking trails. I can sit for hours on our balcony looking at the Giant Sequoia (which is designated a Heritage tree by the city of Portland) and the numerous Douglas Firs in Washington Park. I can feel the energy of the trees even from afar. When I practice my gratitude meditation each morning, I thank the universe for the privilege of being near these magnificent giants.

      So true, Nancy. It’s refreshing!


    Really now, what took them so long. A tree is like a spine, you have the trunk and then all the nerve ending are the branches. If one of the branches get caught the wrong way it is considered a pinched nerve and then there starts the pain (sciatica), so to me that would go to reason that the tree has to have a heart. Even the spine of a book has a heart, if that breaks the book could fall apart showing that it has lost its beat

    Those heart beats are as a result of xylem refilling process in the night as well as in the day( xylem water breaks make a sound of heart beat).

    When I took acid and listened to the trunk of a tree for ages, I heard plumbing noises. Quiet tinkering and clicking and flowing of water, I was convinced it was the functioning of the tree!!

    Trees have a heartbeat, trees sleep and trees communicate through mats of underground fungi..the day is not long off when we have the same regard for plants as we do for animals ( some of us).
