It starts as a tiny, hot coal in your chest. You’re scrolling through Instagram or maybe just sitting in a meeting when someone mentions a coworker's promotion. Suddenly, you aren't just happy for them. You’re scanning for reasons why they didn't deserve it. This is jealousy, or at least, that’s what we call it in casual conversation. But honestly? Most of us are actually talking about envy, and the distinction matters more than you think for your mental health.
Jealousy is a three-person game. It’s the fear of losing something you already have—like a partner or a best friend—to a rival. Envy is the two-person game where you want what someone else has. We use the terms interchangeably, but the brain doesn't see them the same way. When you feel "the one with all the jealousy," you’re often stuck in a neurobiological loop that researchers like Dr. Richard Smith, a leading expert on the subject at the University of Kentucky, have studied for decades.
It’s painful.
The Neuroscience of the Green-Eyed Monster
When you experience intense envy or jealousy, your brain isn't just "being petty." It’s reacting to a perceived threat to your social standing. In the evolutionary past, being at the bottom of the tribe meant less food and fewer chances to survive. Your brain still thinks it’s 10,000 BCE.
Studies using fMRI technology show that when people feel envy, the anterior cingulate cortex lights up. This is the exact same region of the brain that processes physical pain. So, when you say it "hurts" to see your ex with someone else, you aren't being dramatic. Your brain is literally registering a social wound as a physical one.
Then there’s the flip side: Schadenfreude. If that person you're jealous of fails, your brain’s ventral striatum—the reward center—gets a hit of dopamine. It’s a dark cycle. You feel pain when they succeed and pleasure when they fall. This isn't just a character flaw; it’s a hardwired survival mechanism gone haywire in a world of constant digital comparison.
Why Social Media Made Everything 10x Worse
We weren't built for this. Human beings evolved to compare themselves to the twenty people in their immediate village. Now, we compare our "behind-the-scenes" footage to the "highlight reels" of eight billion people.

Social psychologists call this Upward Social Comparison. If you follow someone who seems to have the perfect life, perfect body, and perfect career, your brain doesn't naturally say, "Well, they probably have a team of editors and a lot of debt." Instead, it says, "I am failing."
Leon Festinger, the psychologist who pioneered Social Comparison Theory back in 1954, noted that we have an innate drive to evaluate ourselves by looking at others. But in 2026, the data points we're using are skewed. They’re fake. We are feeding our brains junk data and wondering why we feel like we're starving.
The Difference Between Benign and Malicious Envy
Not all jealousy is created equal. Researchers often split envy into two distinct categories.
Benign envy is actually a motivator. It’s that feeling of "Wow, they did it, maybe I can too." It lacks the desire to see the other person fail. It’s aspirational. You see a friend run a marathon, and instead of feeling bitter, you go buy running shoes.
Malicious envy is the dangerous one. This is the "one with all the jealousy" that leads to bitterness, gossip, and a desire to pull others down to your level. It’s destructive. It leads to what sociologists call "crabs in a bucket" syndrome, where instead of climbing out, the group pulls back anyone who makes progress.
How do you tell which one you’re feeling? Ask yourself: If this person lost what they had tomorrow, would I feel better? If the answer is yes, you’re in the red zone.

Real-World Consequences of Chronic Comparison
Living in a state of constant jealousy isn't just a mood killer. It has physical consequences. Chronic stress from social comparison keeps your cortisol levels spiked. High cortisol is linked to everything from sleep deprivation to weakened immune systems and even heart disease.
Basically, being the one with all the jealousy is slowly poisoning your body.
In the workplace, this manifests as "Tall Poppy Syndrome." It’s especially prevalent in cultures like Australia or certain corporate environments where people are criticized or resented for being too successful. When a team is infected with jealousy, productivity dies. Nobody wants to share ideas because they’re afraid someone will steal the credit or resent the success.
How to Actually Stop Feeling This Way
You can't just "stop" feeling an emotion. That’s not how biology works. If you try to suppress it, it just comes out sideways as passive-aggression.
Instead, you have to practice Cognitive Reframing. When that spike of jealousy hits, name it. "Okay, I am feeling envious right now." This moves the activity from your emotional amygdala to your logical prefrontal cortex. It gives you space.
Another trick? Gratitude practice. It sounds like something on a cheesy Pinterest board, but it’s actually a neurobiological "hack." You cannot feel deep gratitude and intense envy at the same exact moment. They use the same emotional real estate. By forced-focusing on what you actually possess, you starve the jealousy of the attention it needs to grow.

The Surprising Connection Between Jealousy and Ambition
Sometimes, jealousy is a map.
If you are constantly jealous of your friend’s travel photos but you couldn't care less about their new car, that tells you something. It means you value experiences and freedom over material goods. Your jealousy is pointing toward your unfulfilled desires.
Instead of hating the person who has what you want, use that feeling as data. It’s a signal that you are neglecting a part of yourself that wants to grow. The person you’re jealous of is just a mirror showing you what you haven't given yourself permission to pursue yet.
Actionable Steps to Neutralize the Green-Eyed Monster
- Perform a Digital Audit. If someone’s posts consistently make you feel "less than," mute them. You don't have to unfollow them and make it a "thing," but you need to stop the daily micro-doses of inadequacy.
- Practice "Rejoicing" (Mudita). This is a concept from Buddhist philosophy. It’s the practice of finding joy in the good fortune of others. It feels fake at first. Do it anyway. Send the "congrats" text. Buy the celebratory drink. Eventually, your brain starts to believe the signal you’re sending.
- Audit Your Own Worth. Spend five minutes writing down things you’ve accomplished that have nothing to do with anyone else. Internalize your "wins" so your foundation isn't built on being "better than" Neighbor Joe.
- Humanize the Target. Everyone has a "junk drawer" in their life. The person you're jealous of might have a great career but a failing marriage or a chronic health issue. Remembering that everyone is fighting a battle you know nothing about levels the playing field.
- Turn Envy into Mentorship. If you’re jealous of someone’s skill, ask them how they did it. Changing the dynamic from "rival" to "teacher" instantly kills the malice.
Jealousy is a heavy burden to carry. It’s an old-school survival instinct that has become a modern-day toxin. By recognizing the pain for what it is—a biological signal of perceived threat—you can start to dismantle its power over your daily life. You don't have to be the one with all the jealousy anymore; you can just be someone who sees a target and decides to go after it yourself.
Start by closing the app. Look at your own life. There is usually more there than you’re giving yourself credit for.
