Here’s the science
Have you ever walked out to the field in a bad mood, maybe after a tough day at school or an argument at home, and noticed that your pony seemed different? More unsettled, or harder to catch, or just a little less relaxed than usual?
You probably assumed you were imagining it. But here’s the thing: you weren’t. Scientists have actually proven it.
Your pony can tell how you’re feeling. Not in a vague, fuzzy way, but in a real, measurable, scientific way. And the research behind it is one of the most exciting discoveries in horse science in recent years.
How did scientists find this out?
Researchers in France wanted to know whether horses could pick up on human emotions so they designed a clever experiment.
They showed groups of horses videos of people displaying two different emotions: fear and joy. The horses couldn’t touch the people or smell them; they could only watch the screen, just like you watching television.
While the horses watched, the scientists measured two things:
- The horses’ heart rates (how fast their hearts were beating)
- The temperature around their eyes (which rises when an animal is feeling stressed or emotionally activated and scientists can measure this with a special camera)
The results were remarkable. When the horses watched people expressing fear, their heart rates went up and the area around their eyes got warmer – signs that they were feeling more alert and emotionally activated. They also stood in a tense, watchful posture for longer.
Watching someone else’s fear made the horses feel more fearful too.
Scientists have a name for this: emotional contagion. It means emotions can be ‘caught,’ a bit like a cold – one individual experiences an emotion, and it spreads to another. Scientists thought this mainly happened between horses. Now we know it happens between horses and humans too.
🌟 WOW FACT
Horses can catch your emotions from watching your face alone – even on a screen, without being able to hear you, touch you, or smell you. Your face is sending your pony a constant emotional broadcast, whether you realise it or not.
Why would horses evolve this ability?
Horses are prey animals – animals that are hunted by predators in the wild. For a prey animal, picking up on fear signals from others in the group is a life-saving superpower.
If one member of the herd spots a predator and reacts with fear, the others need to pick up on that instantly – not after a long discussion. The faster they catch the emotional signal, the faster they can run.
Over thousands of years of evolution, horses became extraordinarily sensitive to emotional signals in those around them. And when horses began living closely with humans – around 4000 years ago – that sensitivity expanded to include us too.
Your pony isn’t just responding to your body language or your tone of voice. They’re reading your emotional state from your face, processing it, and responding to it, in real time.
It works both ways
Here’s something even more interesting. The same research showed that horses don’t just respond to negative emotions like fear. They also respond to positive ones like joy, though in a different way.
When horses watched the joy videos, their heart rates also changed, but differently, suggesting a more relaxed, curious kind of attention rather than the sharp alertness triggered by fear. Scientists think responding to positive emotions helps horses stay socially bonded with the humans they work with.
So when you’re happy and relaxed around your pony, they really do pick that up. Your good mood isn’t wasted on them. They feel it too.
What this means for you and your pony
This science changes something important about how we think about riding and handling horses.
It means your emotional state isn’t separate from your pony’s experience of a session – it is part of their experience. A rider who arrives tense and anxious is creating tension and anxiety in their horse before they’ve even put a foot in the stirrup. A rider who arrives calm and positive gives their horse a head start toward feeling safe.
This doesn’t mean you have to pretend to be happy when you’re not. Horses can’t be fooled that easily, and you shouldn’t have to perform emotions you don’t feel. But it does mean that taking a few deep breaths before you approach your pony, bringing your own heart rate down before you handle them, isn’t just good for you. It’s good for them.
The best riders in the world know this intuitively. Now the science has confirmed it.
🐴 Try this
Next time you go to see your pony, try a little experiment.
Round 1: Walk to the field or stable when you’re feeling a bit stressed or rushed. Notice how your pony responds to you – do they come to you easily? Do they stand quietly? How do they seem?
Round 2: On a different day, take two minutes before you approach to stand still, breathe slowly, and let yourself feel genuinely calm and unhurried. Then walk to your pony the same way. Notice the difference in how they respond.
You might be surprised by what you find. Scientists call it emotional contagion. Pony people just call it connection.
