Longing for but also avoiding touch: a more nuanced view of our “hunger for touch” during the time of COVID
During the COVID-19 pandemic, social isolation did not increase the general desire for touch but rather narrowed tactile interactions to close networks, while the study found that receiving affective touch improved mood whereas an unmet desire for touch was linked to higher stress and loneliness, highlighting the distinct emotional roles of experienced versus desired touch.

The Great Human Hug-ometer
Imagine your brain has a special, invisible dashboard just for human connection. One of the most important gauges on this dashboard is "touch." We all know that a warm hug, a gentle pat on the back, or a high-five isn't just about skin rubbing against skin; it's a secret language our bodies use to say, "You are safe," "I like you," and "We belong together." Scientists call this "affective touch." It's the kind of contact that makes us feel calm and connected, distinct from a handshake or a doctor's exam. But here's the tricky part: just like a car that won't start if the battery is dead, our social batteries sometimes run low when we can't get enough of this special contact. This is often called "skin hunger."
For a long time, people assumed that if you locked people away from each other—like during a global pandemic—they would instantly start craving hugs like a plant craves sunlight. The story seemed simple: no touch equals more hunger for touch. But human brains are messy, complex, and full of surprises. They don't just react to empty space; they react to who is in that space. Are we talking to a best friend or a stranger? Are we feeling safe or scared? This paper dives into that messy middle ground to see if isolation really makes us all desperate for a cuddle, or if it just changes who we want to cuddle with.
The Great "Hug vs. Stranger" Experiment
During the height of the COVID-19 pandemic, a team of researchers decided to test the "skin hunger" theory with a massive, global experiment. They didn't just ask people if they missed hugging; they asked 1,788 people from 61 different countries to fill out a detailed survey. They wanted to know two very specific things: How much touch were people actually getting? And how much touch did they want? They also asked people to rate how pleasant they imagined being touched on different parts of their bodies, like the back, the arm, or the face.
Here is the twist they found: The world wasn't exactly what everyone expected. The big, dramatic idea that "isolation makes you crave touch" turned out to be a bit of a myth. The study suggests that being isolated didn't automatically make people want more touch in general. Instead, isolation acted like a filter or a spotlight. It didn't increase the overall "hunger" for touch; it just changed the menu.
People who were isolating reported getting more touch from the people they lived with—like partners, parents, or kids—but significantly less touch from strangers. It's as if their social circle shrank down to a tiny, cozy circle, and the door to the outside world was locked tight. While they were getting more hugs from their "inner circle," they weren't suddenly desperate for a hug from a stranger. In fact, the desire for touch from strangers stayed low, or even dropped a little. The study found that isolation didn't predict a general increase in wanting touch; it just reshaped who people were touching.
The "Wanting" vs. "Getting" Paradox
One of the most fascinating discoveries in the paper is the difference between "getting" touch and "wanting" it. The researchers found that these two things actually pull in opposite directions when it comes to our mood.
Think of it like a thermostat. If you are getting a lot of affectionate touch from people you know, your mood tends to be better. You feel less lonely, less stressed, and less sad. It's like the thermostat is set to "comfort." But here's the weird part: if you want more touch than you are actually getting, your mood gets worse. The more you crave a hug that isn't happening, the more stressed and lonely you feel.
The study suggests that "wanting" touch isn't just a neutral wish; it's a signal that something is missing. When people reported wanting more touch, it was a strong predictor of negative feelings like stress and loneliness. It's as if the brain is sounding an alarm: "Hey, we need that connection right now!" But interestingly, just being isolated didn't automatically turn on that alarm. The alarm only went off if the person felt they weren't getting enough touch despite their situation.
The Body Map and the "Imaginary Hug"
To get even more specific, the researchers used a digital "Body Map" tool. Imagine a blank outline of a human body on a screen, and you have to color it in. If you think a stranger touching your head would be gross, you color it red. If you think a partner touching your shoulder would be nice, you color it blue.
The results were super clear. Everyone, regardless of whether they were isolated or not, hated the idea of strangers touching them, especially in private areas like the head or shoulders. But women were even more cautious than men about stranger touch. When it came to people they knew, the "blue" zones (the pleasant spots) were much bigger.
The team also asked people to imagine being touched in videos. They found that people who were already getting lots of touch rated these imaginary touches as less pleasant. It's like if you've just eaten a whole pizza, a slice of pizza doesn't look as delicious. But for people who wanted more touch, those imaginary touches looked incredibly pleasant and vivid. Their brains were essentially saying, "Oh wow, that looks amazing!" because they were hungry for that connection.
The Bottom Line
So, what's the takeaway from this massive study? The idea that isolation makes us all desperate for a hug is too simple. Instead, isolation seems to act like a funnel. It narrows our world down to the people we trust most. We get more touch from our families and partners, but we shut the door on strangers.
The study suggests that our mood depends less on how isolated we are and more on whether we are actually getting the touch we need from the people around us. If you are getting good, warm touch from your inner circle, you're probably doing okay. But if you are craving touch and not getting it, that's when the stress and loneliness kick in. It turns out that it's not just about having a "hunger" for touch; it's about whether the kitchen is open and serving the right food to the right people.
