Why Other People’s Moods Rub Off on You, According to Therapists

You know how some mornings just feel effortlessly good? It’s a sunny day, your coffee hits just right, you look great in your new clothes. You’re happy as anything.

But then your partner walks into the room, and you know something’s off. They don’t say anything — they don’t need to — but suddenly it feels like your inner weather has flipped. You try not to take it personally, but you can literally feel their negative energy chewing up your good mood, and before long, the two of you are banging around cups and huffing at one another.

What’s actually happened here?

Being affected by other people’s moods is human, and there’s a scientific reason it happens. It turns out that while we can all get caught in the crossfire of another person’s feelings, some of us are far more susceptible to it than others.

Why Other People's Moods Rub Off On You

Being affected by other people’s moods is no accident. We’re wired to live in groups, and tuning in to each other helps us stay safe and connected; it’s a survival instinct. So when we’re around someone who is experiencing a strong emotion, the part of our brain that handles empathy kicks in. Empathy is the ability to sense and understand what someone else is feeling, and in many cases, to emotionally “join” them there.

As Charity Hagains, a licensed professional counselor and co-founder at NOYAU Wellness Center explains: “When we perceive another person's emotional state, our brain automatically activates empathy-related networks. This includes the mirror neuron system and limbic structures such as the amygdala and anterior insula. When activated, they allow us to simulate others’ emotions.”

In plain English, your brain is mirroring what it sees and feels in the other person, which is why their bad mood can suddenly feel like yours. This process is automatic and happens to most of us. However, the degree to which we experience empathy differs, depending on both your brain’s structure and your personality. 

Why You Feel It More Than Others

The Big Five theory of personality measures five broad traits — Openness, Conscientiousness, Extraversion, Agreeableness and Neuroticism. How highly you score on each trait gives an insight into why you think and behave the way that you do, and research shows a clear connection between certain Big Five traits and how empathetic a person may be. Let’s break it down.

Agreeableness: When you can’t relax if someone’s upset

Agreeable people are kind and friendly; they’re all about keeping the peace and being liked by others. If someone else is unhappy or upset, it messes with the harmonious balance they strive to create, so people who score highly on this trait are more likely to be tuned in to other people’s feelings and try to account for them.

In many cases, this can be a good thing. Agreeable people are more likely to care for those around them and lend a shoulder to cry on. However, there are times when you’re too empathetic and give more than you can afford to, leaving yourself feeling drained.

Neuroticism: When worry turns up the volume

Sprinkle in a little Neuroticism, and hold tight, you’ve got a recipe for real emotional overload. Neuroticism measures a person's tendency to experience negative emotions like anxiety, anger and vulnerability, and the study mentioned above found a strong link between Neuroticism and the distress someone feels when dealing with people's pain.

As Hagains explains, if you score high on both of these traits, you may find it hard to separate yourself from other people’s bad moods. “Individuals higher in Agreeableness and Neuroticism tend to be more sensitive to others' emotional states, making them more prone to emotional contagion,” she explains. If you’re wondering about “emotional contagion,” it’s simply the idea that emotions can spread from one person to another, much like a yawn or a laugh.

Openness: Big imagination, big feelings

The same research found that Openness only has a mild correlation with empathy, but it still plays a role. People who score high in this trait are usually imaginative, curious and interested in ideas and experiences, and that rich inner world can make it easier to step into someone else’s shoes.

“Those high on the Openness scale may have the ability to create an emotional picture so vibrant that they enter the very core of the others’ suffering,” explains Aubrey B. Hunt, a psychotherapist, LCSW, LCADC, CCS, CCTP, at Willow Ridge.  Since Open people find it easy to imagine what a friend, partner or even a client is going through, they may end up feeling the same emotions quite intensely.

The Calm Ones Have an Edge

Emotional stability is essentially the opposite of high Neuroticism. If you’re low on Neuroticism, it means you are calm, less emotionally reactive and resilient under pressure. You won’t be surprised to learn that all of these tendencies act as a kind of buffer when you’re confronted with someone else’s emotions.

People who are naturally emotionally stable (i.e. low in Neuroticism) are more likely to remain chilled and avoid getting swept up in the tsunami of another person’s feelings. Since they aren’t as reactive, they can keep their own feelings in check without absorbing anyone else’s.

Conscientiousness may also play a role here. While the study found only a modest link between someone’s Conscientiousness and their level of empathy, we know that Conscientiousness is all about being organized, reliable and goal-oriented. These traits may well help a highly Conscientious person stay on top of social responsibilities without getting knocked off course by someone else’s feelings.

While not conclusive, the research goes some way toward showing us why some people absorb people’s emotions more than others. In particular, those high in both Neuroticism and Agreeableness are likely to “catch” someone’s bad mood.

How to Stop Soaking Up Everyone Else’s Mood

Your personality, and how you score on the Big Five personality test, is relatively static over time, but that doesn’t mean you are destined to feel overwhelmed by other people’s feelings forever. As Hagains puts it, “Being empathetic and having the ability to tune in to those around you is not a liability, but a real gift; one that simply needs refinement.” With that in mind, let’s take a look at some of the science-backed ways you can protect your emotional well-being when others’ moods get in the way.

First Step: Check If It’s Even Your Mood

When a bad mood hits, is it always yours? Some people aren’t even aware that what they're feeling is someone else’s mood of the moment, so if your sunny mood suddenly turns stormy for no obvious reason, Hunt says you should pause and look for three telltales: “...quick changes in your emotions that do not correspond to your situation, feeling tired or nervous after meeting with certain people, or having physical tension that seems to go with another person's mood.”

If that sounds familiar, take a second to scan what’s been happening around you and who you’ve been with. Noticing that you’re reacting to someone else’s emotional state, rather than your own situation, is a powerful first step in shifting it.

Not My Circus, Not My Mood

You’ve heard the saying “Not my circus; not my monkeys.” It describes the feeling of deciding something is just not your problem, and the same mindset can apply to emotions. Let’s say you’ve noticed that an emotion is not yours, so you stop for a moment and label it. That can mean quite literally thinking, “Oh, that feeling is not mine to carry.”

Hagains calls this “cognitive reprisal,” and explains that having the skill to change how you look at the emotions you notice can make a big difference in how you react to them. She recommends starting by asking yourself a simple question: “Does this belong to me?” If the answer is no, you can start reframing the emotion by using some of the following phrases aloud or in your head: or 

• “This is their experience, not mine.”
• “My friend is feeling X. That doesn’t mean I have to.”
• “I am not responsible for their feelings.”
• “I can support someone without taking on their emotional state.”

Reframing the emotion as someone else’s gives you the breathing room to get in touch with how you feel, instead of how they feel. It may feel a little weird at first, especially if you’re used to being the “emotional sponge” in your relationships. However, do it a few times and it will start to feel more natural.

Come Back to Your Own Headspace

Mindfulness and grounding techniques are always worth pursuing, especially if you want to get in better touch with your own emotions. Practices like breathwork, body scans, or noticing your senses in the moment can help you build resilience and a stronger sense of self.

The upshot is that you may approach situations in a calmer and more measured way. When your own emotional base feels steadier, other people’s moods are less likely to knock you completely off balance.

When It’s Time for Extra Support

Of course, if taking on others’ emotions is hindering your everyday life, you may need more support. This can be especially true if you identify as a highly sensitive person (HSP), tend to people-please, or often feel responsible for everyone else’s happiness.

Talking to a therapist can help you unpack why you absorb so much, where those patterns came from, and how to set healthier limits. As Hunt notes, “Cognitive-behavioral techniques that sharpen your perception of thinking, feeling and sensing can also be a tool for you to stop and label the source of your emotional reaction.” In practice, that might mean learning to spot your triggers, challenge unhelpful thoughts and practice new ways of responding.

If someone has a tendency to fawn or be overly sympathetic, working on assertiveness and personal boundaries can also be helpful. A therapist can guide you in expressing your needs without guilt, so caring for others doesn’t always come at the cost of yourself.

You Can Have Empathy Without Mood Exhaustion

While your personality can certainly play a role in how empathetic you are, and how much you absorb other people’s moods, how you manage it is up to you. Being empathetic is a powerful, human trait, but if it tips over into constant emotional contagion, you may need better boundaries. “To strengthen emotional boundaries, practice these skills regularly,” Hagains says. “The goal is to care for others without losing your peace."
