Is it normal to have mood swings in relationships?

Absolutely. We've all been there—one moment you're feeling deeply connected with your partner, and the next, you're wondering why everything feels off. Relationships are emotional by nature, and it's normal for moods to fluctuate. It's not just you or your partner, it's part of the rhythm of any close relationship.

Mood swings can come from stress at work, family dynamics, or even internal anxieties we don't always recognize right away. Our emotions affect our interactions, and that's where these swings can feel most intense. Dr. Sue Johnson, author of Hold Me Tight, says, “Emotional vulnerability is where the real work of love lies.” In relationships, those mood shifts expose vulnerabilities—both yours and your partner's.

But don't worry. These shifts don't mean there's something wrong with your relationship. Mood swings can be an invitation to look deeper into what's driving them and how to better connect through those moments.

What do mood swings feel like?

Mood swings feel like a sudden shift in the emotional atmosphere—one second everything seems calm, and the next, the air feels heavy, tense, or unpredictable. You might find yourself feeling agitated for no apparent reason, or your partner's words may trigger an unexpected reaction in you.

For some, these mood changes are like quick storms—sudden and intense. For others, it's a slow build-up of emotions that eventually spills over. When mood swings happen in relationships, they can feel confusing or even alarming. One minute you're sharing a laugh, and the next, you're not sure why the conversation feels strained. That's because our moods are linked to complex factors like stress, diet, and even sleep. When they shift, it can feel like you're standing on unstable ground.

Author and relationship therapist Esther Perel highlights this emotional complexity: “We all come to relationships with baggage. Sometimes, we just don't know what's in our suitcase until it starts spilling out.” Understanding mood swings in yourself and your partner means recognizing that there's often more happening beneath the surface than either of you may realize in the moment.

5 potential causes of mood swings in relationships

Mood swings don't just happen out of nowhere. When we dig deeper, we can find a range of causes that might be influencing the emotional highs and lows in our relationships. Some of these causes are external, like stress from work, while others are more internal, such as hormonal shifts. Let's take a closer look at five of the most common culprits.

Stress and overwhelm

One of the biggest contributors to mood swings is stress, which can creep in from all areas of life. Whether it's work deadlines, financial pressures, or family responsibilities, stress builds up and eventually spills over into our relationships.

Feeling overwhelmed can make even small things feel insurmountable, triggering emotional reactions that seem out of proportion. You may find yourself snapping at your partner over something minor or withdrawing because everything feels too much. When stress is high, it's hard to think clearly, and patience tends to run thin.

According to Dr. John Gottman, a renowned relationship expert, “Stress and how we handle it is one of the biggest predictors of relationship success.” We can't avoid stress, but how we manage it can determine whether it causes unnecessary friction or strengthens our connection.

Hormonal changes

Hormones play a huge role in how we feel on a day-to-day basis, and they can cause mood swings that are completely out of our control. Hormonal fluctuations, especially in women during their menstrual cycle, pregnancy, or menopause, can create emotional ups and downs that feel overwhelming. But it's not just women—men experience hormonal changes too, often linked to aging or stress.

These changes can create feelings of irritability, sadness, or even anxiety. One day, you might feel great and connected with your partner; the next day, you could feel emotionally distant without knowing why. It's important to recognize these hormonal shifts to prevent them from creating unnecessary misunderstandings in relationships.

In the book The Female Brain, Dr. Louann Brizendine explains, “Hormones are nature's mood-altering drugs,” highlighting how much control they have over our emotional states. Being aware of these fluctuations allows us to be more compassionate with ourselves and our partners when mood swings strike.

Lack of sleep

We've all had those days where we're running on empty after a terrible night's sleep. When sleep is compromised, it's not just our physical energy that takes a hit—our emotional resilience does too. Sleep deprivation can cause mood swings, making you more prone to anger, frustration, and emotional outbursts.

In relationships, this lack of sleep can manifest as irritability, impatience, or feeling emotionally off-kilter. You might find yourself getting annoyed over little things, or your partner might seem distant because they're exhausted. These reactions are natural when your brain hasn't had time to reset and recover overnight.

Research from Harvard Medical School suggests that chronic sleep deprivation can impact the parts of the brain responsible for emotional regulation. In other words, when we're tired, it's harder to keep our emotions in check, which can create turbulence in a relationship that wouldn't normally exist.

Diet and nutrition

What we put into our bodies has a direct impact on how we feel emotionally. Poor nutrition, or diets high in sugar and processed foods, can cause energy crashes that leave you feeling irritable or anxious. If you've ever felt a sudden dip in mood after eating junk food, you've experienced this firsthand.

On the other hand, a well-balanced diet full of fresh fruits, vegetables, and healthy fats can stabilize your mood and help you manage stress better. Omega-3 fatty acids, for example, have been shown to boost mood and reduce symptoms of depression. When you and your partner are mindful of what you're eating, it's much easier to maintain emotional balance in the relationship.

Dr. Mark Hyman, author of Food: What the Heck Should I Eat?, notes, “The food you eat is either the safest and most powerful form of medicine or the slowest form of poison.” When we're conscious of how our diet influences our emotions, we're better equipped to keep mood swings at bay and communicate more effectively with our partners.

Mental health concerns

Sometimes, mood swings are a symptom of deeper mental health issues like anxiety, depression, or bipolar disorder. These conditions can cause unpredictable shifts in emotions, from extreme highs to overwhelming lows, often without a clear trigger. If one or both partners struggle with mental health concerns, mood swings can feel even more intense and difficult to manage.

It's crucial to address these concerns head-on. Ignoring them or hoping they'll resolve on their own can lead to a breakdown in communication and understanding. Seeking professional help—whether through therapy, counseling, or medical treatment—can make a world of difference in how you manage mood swings in a relationship.

Psychologist Dr. Kay Redfield Jamison, a leading expert on mood disorders, writes in An Unquiet Mind, “Mood disorders shape the emotional landscape of those affected, but they do not define them.” Understanding that mental health plays a role in emotional fluctuations allows us to approach our relationships with greater empathy and patience.

Mood swings in men vs women: Are there differences?

While both men and women experience mood swings, the causes and expressions of these shifts can vary between genders. Women often face mood changes tied to hormonal fluctuations, such as during menstruation, pregnancy, or menopause. These hormonal cycles can make mood swings more frequent or pronounced at certain times of the month or life.

Men, on the other hand, experience mood swings that may be more closely linked to external stressors like work pressures or financial concerns. Testosterone levels also fluctuate in men, particularly as they age, which can contribute to changes in mood and energy. However, men are often socialized to hide their emotions, which means their mood swings may come out in different ways—through withdrawal, irritability, or even anger.

Understanding these differences can help couples recognize the unique challenges they face and approach each other with greater compassion. It's important to avoid gender-based stereotypes when discussing mood swings and instead focus on the individual's unique experience.

How mood swings affect relationships: 7 ways

Mood swings don't just affect the individual experiencing them—they ripple through the relationship, creating emotional friction that can be hard to navigate. Here are seven common ways mood swings can impact relationships:

Communication breakdown: When moods shift quickly, it's easy to misinterpret what the other person is feeling, leading to misunderstandings or arguments.
Emotional distance: If one partner is overwhelmed by their emotions, they may pull away, creating a sense of detachment or isolation for the other person.
Lack of predictability: Constant mood changes can make the relationship feel unstable, leaving both partners unsure of what to expect next.
Strain on patience: It takes energy and patience to deal with mood swings, and over time, that patience can wear thin, leading to frustration or resentment.
Impact on emotional intimacy: When moods are unpredictable, it can be hard to feel close or emotionally connected, as both partners may be on edge.
Increased tension and arguments: Mood swings can lead to heightened emotions, causing small disagreements to escalate into full-blown conflicts.
Reduced trust and security: If mood swings create a sense of unpredictability, one or both partners may start to feel less secure in the relationship, leading to doubts or fear of emotional instability.

Each of these effects is manageable, but only if both partners are aware of what's happening and are willing to work together to address the root causes of the mood swings.

Communication breakdown

Mood swings can easily lead to a breakdown in communication. When emotions are high or unpredictable, it's hard to express yourself clearly or understand your partner. You might say things in the heat of the moment that you don't mean, or worse, you might shut down completely, avoiding the conversation altogether.

On the receiving end, your partner could misinterpret your emotional state, assuming you're angry at them or frustrated when in reality, you're just overwhelmed or stressed. This breakdown in communication often leads to confusion, hurt feelings, and an increased emotional gap between you and your partner.

Effective communication is the foundation of any healthy relationship. When mood swings disrupt this foundation, it's essential to hit the pause button and revisit the conversation when emotions are more balanced. “Clear communication is the key to healthy relationships,” says Dr. Harriet Lerner, author of The Dance of Connection. “We must learn to stay connected even when emotions run high.”

Emotional distance

When mood swings cause emotional turbulence, it's easy for emotional distance to creep into the relationship. One partner may withdraw to protect themselves from the intensity of their feelings or the perceived volatility of the other person. This emotional distancing, while often subconscious, creates a barrier between partners.

Over time, this distance can lead to feelings of isolation or loneliness within the relationship. If one or both partners are dealing with mood swings and pulling away emotionally, it becomes harder to maintain a sense of connection. In the long term, this emotional distancing can erode trust and intimacy.

The key to overcoming emotional distance is recognizing when it's happening and making a conscious effort to close the gap. Sometimes, it's as simple as asking for a hug or making time for a conversation when you're both in a better headspace. Other times, it might require more deliberate actions like spending quality time together or seeking counseling to address the underlying issues.

Lack of predictability

One of the most challenging aspects of mood swings in relationships is the lack of predictability they create. When your partner's mood can shift suddenly, it becomes difficult to anticipate how they will react in different situations. This unpredictability can lead to anxiety or hesitation about starting certain conversations or planning activities, as you're unsure of what version of your partner you'll be facing.

This instability can make the relationship feel shaky, as neither partner feels they have a clear emotional landscape to rely on. Predictability in emotions is a form of emotional security, and when that's taken away, it can erode trust and comfort in the relationship.

We all crave some level of stability in our connections. Without it, even the most loving relationships can feel unstable or fragile. It's crucial for both partners to work together to create as much emotional steadiness as possible, even in the face of mood swings.

Strain on patience

Dealing with mood swings can stretch your patience to its limits. When you're navigating your partner's emotional ups and downs, it's easy to feel drained or frustrated, especially if it feels like the mood changes are happening frequently or without explanation.

Over time, this strain can lead to resentment. You might start to feel like you're always the one trying to stabilize the relationship, or that your partner's emotional volatility is taking a toll on your well-being. Patience is a finite resource, and if mood swings continue unchecked, it can leave you feeling worn out or emotionally exhausted.

Maintaining patience requires both empathy and self-care. It's important to recognize that your partner's mood swings aren't necessarily something they can control. At the same time, taking care of your own emotional health—through boundaries, rest, or seeking support—is key to sustaining patience in the long run.

Impact on emotional intimacy

Emotional intimacy thrives in an environment of openness, trust, and stability. When mood swings disrupt the emotional flow in a relationship, they can create barriers that prevent partners from feeling close. One minute you might feel deeply connected, and the next, a sudden mood shift can create emotional distance that feels hard to bridge.

This inconsistency can make it difficult to maintain the sense of vulnerability that emotional intimacy requires. When you're unsure how your partner is going to react, it's natural to put up emotional walls to protect yourself from potential hurt. Unfortunately, these walls also block the very connection both of you crave.

In her book The Seven Principles for Making Marriage Work, Dr. John Gottman points out that emotional intimacy is built through everyday interactions. When mood swings interrupt these interactions, it's easy to miss out on those small but meaningful moments that strengthen emotional bonds.

Increased tension and arguments

Mood swings often lead to heightened tension, and when emotions are running high, small issues can quickly escalate into full-blown arguments. What starts as a minor disagreement can spiral into a major conflict when one or both partners are emotionally on edge. The unpredictability of mood swings means that even the most mundane conversations can turn into heated debates.

When arguments become frequent due to mood swings, they can start to feel like a permanent feature of the relationship. Both partners may find themselves walking on eggshells, unsure of when the next blow-up might occur. This constant tension isn't just exhausting—it also makes it harder to resolve conflicts in a healthy way.

It's essential to recognize when mood swings are the root cause of arguments and take steps to defuse the situation before it escalates. Sometimes, stepping away from a conversation to cool down can prevent unnecessary conflict and give both partners time to regain emotional clarity.

Reduced trust and security

Trust and security are the pillars of any strong relationship. When mood swings create unpredictability, they can erode that sense of safety both partners rely on. If you never know how your partner is going to react, it becomes harder to trust that they'll be emotionally available when you need them. This emotional instability can lead to doubts about the strength of the relationship or fears that things could fall apart at any moment.

Over time, this loss of trust can impact the very foundation of the relationship. You might start second-guessing your partner's intentions or feel unsure about how secure your bond truly is. It's important to address these feelings early before they create deeper issues of insecurity and mistrust. Open, honest conversations about the impact of mood swings on your emotional safety can help rebuild trust and strengthen your connection.

5 ways to manage mood swings in relationships

While mood swings can feel overwhelming, there are concrete steps you and your partner can take to manage them and minimize their impact on your relationship. Here are five effective strategies for navigating mood swings together:

Talk to them: Open communication is essential. If you notice your partner's mood shifting, ask how they're feeling instead of making assumptions.
Validate their feelings: Acknowledge their emotions without trying to fix them right away. Sometimes, simply knowing they're understood can ease the intensity of a mood swing.
Remain empathetic and understanding: Remember, mood swings aren't always within your partner's control. Approach them with compassion instead of frustration.
Offer to help: Ask if there's anything you can do to support them, whether that's giving space, listening, or helping with tasks that feel overwhelming.
Learn how to control mood swings naturally: Encourage healthy habits like regular sleep, balanced nutrition, and stress management techniques to keep mood swings in check.

By actively working together to manage mood swings, you can not only reduce their negative effects but also strengthen the emotional resilience of your relationship.

Talk to them

One of the most effective ways to manage mood swings in a relationship is through open and honest communication. When you notice your partner's mood shifting, instead of retreating or making assumptions about what they're feeling, ask them directly. Something as simple as, “Hey, I noticed you seem a bit off. Want to talk about it?” can open the door to understanding what's really going on.

By initiating the conversation, you're showing that you care and are willing to engage, even if it's uncomfortable. Avoiding the issue only builds tension, while talking about it can release some of that pressure. Keep the conversation gentle and non-judgmental—your goal is to create a safe space where they feel comfortable opening up.

Dr. Gary Chapman, in his book The Five Love Languages, emphasizes the importance of talking through emotions. He writes, “Love is a choice you make every day, and part of that choice is choosing to engage with your partner, even in difficult moments.” This reminder shows us that dialogue, even during emotional storms, strengthens the foundation of your relationship.

Validate their feelings

When your partner is experiencing a mood swing, one of the most powerful things you can do is validate their feelings. Instead of dismissing their emotions or trying to fix the situation right away, acknowledge how they're feeling. Saying something as simple as, “I understand you're feeling frustrated right now, and that's okay,” can go a long way in helping them feel heard and supported.

Validation is not about agreeing with everything they say or feel, but rather recognizing their emotional experience as valid. Too often, mood swings are met with frustration or dismissal, which can make the person experiencing them feel isolated or misunderstood. When you validate their feelings, you're creating a sense of emotional safety, which is crucial during turbulent times.

Relationship expert Dr. Brene Brown notes, “Rarely can a response make something better; what makes something better is connection.” By validating your partner's feelings, you're building that connection, showing them they're not alone in what they're going through.

Remain empathetic and understanding

Empathy is the glue that holds relationships together, especially when mood swings make things feel shaky. Instead of reacting to your partner's emotional shifts with frustration or anger, try to approach the situation with empathy. Ask yourself, “How would I feel if I were in their shoes right now?” Understanding that mood swings often come from stress, hormonal changes, or other factors outside their control can help you respond with kindness rather than impatience.

Being empathetic doesn't mean ignoring your own feelings—it's about balancing your emotional needs with your partner's. Sometimes, just saying, “I know this is hard for you, and I'm here” can provide a sense of comfort and connection. Empathy allows you to stay emotionally engaged, even when it's tough, and reminds your partner that they aren't alone in their struggles.

As relationship therapist Esther Perel says, “Empathy is the antidote to shame.” When we approach our partner with empathy during their mood swings, we dissolve any feelings of embarrassment or guilt they may have, and create a space where healing and connection can flourish.

Offer to help

When your partner is in the middle of a mood swing, offering to help can make a big difference. Sometimes, they may not know exactly what they need, but your willingness to step in and provide support can be incredibly reassuring. Whether it's taking care of a task that's overwhelming them or simply sitting with them in silence, your offer of help shows that you're in this together.

You don't have to fix everything—mood swings can't always be solved with action. But offering to help, whether it's through practical support or emotional reassurance, signals that you're there for them. Ask open-ended questions like, “Is there anything I can do to make things easier for you right now?” and be prepared to follow through on their response, even if they just need space.

Sometimes, the most meaningful form of help is just being present. According to Dr. Sue Johnson, the creator of Emotionally Focused Therapy, “In moments of vulnerability, knowing that we can rely on our partner to show up is one of the most powerful reassurances we can receive.” Offering to help, even in small ways, reinforces that emotional safety and trust.

How to control mood swings naturally

While mood swings can feel overwhelming, there are natural ways to help stabilize them and reduce their impact on your relationship. The key is adopting habits that promote emotional balance and resilience. Here are a few methods to try:

1. Prioritize sleep: A lack of sleep is one of the biggest contributors to mood instability. Make sure both you and your partner are getting enough rest, aiming for 7-9 hours of quality sleep each night. Creating a calming bedtime routine can also help your body and mind unwind.

2. Eat a balanced diet: As we mentioned earlier, what you eat has a direct effect on your emotions. Avoid processed foods and sugars, and incorporate more mood-boosting nutrients like omega-3 fatty acids, leafy greens, and lean proteins.

3. Exercise regularly: Physical activity is a natural mood booster. Whether it's yoga, running, or a brisk walk, movement helps release endorphins that improve your emotional state. Even short bursts of exercise can have a lasting impact on your mood.

4. Practice mindfulness and relaxation techniques: Meditation, deep breathing, and mindfulness exercises can help calm your mind and regulate your emotions. These techniques provide tools to manage stress before it leads to a mood swing.

5. Stay connected: Emotional support from friends, family, or a therapist can help you stay grounded during difficult moments. Sometimes, talking through your feelings with someone you trust is all you need to prevent a downward spiral.

By incorporating these natural strategies, you can help control mood swings before they escalate, creating a more balanced emotional environment for both you and your partner.
