Is Rewatching Shows a Sign of Mental Illness? Here’s What Psychology Says

You’ve been there—scrolling through endless streaming options, only to click play on the same series you’ve already watched three times. Maybe it’s The Office, Friends, or that childhood favorite that feels like coming home. And then comes the nagging thought: Does this mean something’s wrong with me?

Let’s settle this once and for all.

No, rewatching the same TV show is not, by itself, a sign of mental illness. Period.

But here’s the thing—while the behavior itself isn’t a red flag, why you’re doing it and how much you’re doing it can tell a more nuanced story. Let’s break down what psychology actually says about this habit.

What Does It Mean to Rewatch a TV Show?

Rewatching familiar content is incredibly common. In fact, it’s so widespread that psychologists have given it serious attention. According to research cited by Social and Personality Psychology Compass, more than 95% of people have rewatched a movie or TV episode for comfort and emotional regulation.

Psychologists use terms like “comfort TV” and even “cinematherapy” to describe how familiar media can improve mood and reduce stress. When you rewatch a show, your brain isn’t being lazy—it’s actually engaging in a form of emotional self-care.

Dr. Chivonna Childs, a psychologist at Cleveland Clinic, explains that comfort shows give us “a break from the normal things that are going on in life right now”. They’re stories we resonate with, characters we connect with, and worlds we feel safe in.

Is Rewatching Shows a Sign of Mental Illness?

The short answer is no. Rewatching familiar content is not considered a mental illness on its own.

Mental health conditions are diagnosed based on a constellation of symptoms that significantly impair daily functioning—not on a single behavior like watching the same show repeatedly. The DSM-5 (the diagnostic manual used by mental health professionals) doesn’t list “rewatching TV shows” anywhere as a criterion for any disorder.

As one analysis put it: “Compulsive, distress-driven rewatching can overlap with symptoms of depression, anxiety, OCD, ADHD, and PTSD, but the behavior alone doesn’t diagnose any of them“. The key distinction is whether the behavior is driven by compulsion and distress, or by choice and comfort.

Why Do People Rewatch the Same Shows?

There are several scientifically-backed reasons why people return to familiar content:

1. Predictability Reduces Anxiety

When you know exactly what’s going to happen, your nervous system can relax. There’s no suspense, no emotional whiplash, no uncertainty. For someone with anxiety, this predictability is especially powerful. As the Cleveland Clinic notes, “someone with anxiety may like rewatching the same show because they already know what’s going to happen in the end”.

2. Lower Cognitive Load

Your brain has to work harder when processing something new—new characters, new plotlines, new rules of the world. Familiar shows require less mental effort, allowing your brain to shift into a lower-energy mode. Research indicates that watching familiar TV shows can restore our feelings of self-control after periods of mental exertion.

3. Emotional Regulation and Comfort

Rewatching favorite shows helps people manage their emotions. When we’re stressed or emotionally depleted, we naturally gravitate toward known stories because they offer a contained emotional experience. As Psychology Today explains, “when rewatching familiar shows, we receive the stories and emotions we expect. We know how the episodes end and—more importantly—how we’ll feel when they end”.

4. Nostalgia and Connection

Nostalgia is a powerful emotion that can boost mood, increase feelings of belonging, and even reduce anxiety. Rewatching older shows can reconnect people with specific memories, routines, or phases of life. Plus, when you repeatedly watch a series, characters can begin to feel emotionally familiar—almost like reconnecting with old friends.

5. The Mere Exposure Effect

Simply put, we like things more the more we’re exposed to them. With shows we enjoy, repetition deepens our appreciation and attachment.

Can Anxiety Make You Rewatch Familiar Shows?

Yes—and this is where it gets interesting. Anxiety can absolutely make you more likely to rewatch familiar content.

When you’re anxious, your brain is already processing a high cognitive load. New shows present unexpected twists and turns, while familiar shows give your brain a rest. The pandemic era made this pattern especially visible—many people turned to old favorites rather than new content because they were already overwhelmed.

Research shows that people are more likely to start rewatching the same show repeatedly when they feel depleted or emotionally drained. When we feel overwhelmed, our brains crave the familiar.

This doesn’t mean anxiety causes rewatching, or that rewatching means you have anxiety. Rather, it’s one possible coping strategy that anxious individuals might use—and a generally healthy one at that.

Is It a Coping Mechanism?

Yes, rewatching familiar shows is often a coping mechanism—and that’s not necessarily a bad thing.

Research from the University at Buffalo found that people often use favorite television shows as a coping mechanism during periods of stress, rejection, or emotional fatigue. In many cases, comfort TV acts as a form of emotional regulation, helping people decompress, relax, and temporarily disconnect from daily stress.

Psychologists call this “emotional regulation”—the process of managing your emotional state. Watching a familiar show is one way to do that. It’s not so different from listening to a favorite song, eating comfort food, or looking at old photos.

However, like any coping mechanism, it becomes problematic when it’s the only way you cope, or when it starts interfering with other aspects of your life.

When Could It Be a Concern?

While rewatching shows is generally harmless—and can even be emotionally beneficial—there are times when it might signal something worth paying attention to.

Here are some signs that your rewatching habit might be cause for concern:

As psychotherapist Jill Lewis, MA, LCSW, puts it: “There is a point when a couple episodes turns to a dozen a day and you may need to reevaluate”.

It’s also worth noting that binge-watching, specifically, has been linked to increased depression, anxiety, and stress in some studies. But there’s a difference between rewatching a favorite show for comfort and binge-watching compulsively to escape.

When Should You Talk to a Mental Health Professional?

If you’re wondering whether your rewatching habit is a problem, ask yourself these questions:

1. Is it causing significant distress? Do you feel guilty, ashamed, or anxious about how much you watch?
2. Is it interfering with your life? Is it affecting your work, relationships, or physical health?
3. Is it your primary coping mechanism? Do you have other ways to manage stress and difficult emotions?
4. Is it escalating? Are you watching more and more, or finding it harder to stop?

If you answered “yes” to several of these, it might be worth talking to a mental health professional. Not because rewatching is inherently bad—but because the underlying reasons (anxiety, depression, avoidance, etc.) might benefit from professional attention.

Remember: A qualified mental health professional should evaluate symptoms in the context of a person’s overall experiences and functioning. One behavior alone—even a frequent one—is never enough to diagnose a mental health condition.

Bottom Line

Rewatching the same TV show over and over is not a sign of mental illness. It’s a common, normal, and often healthy way to regulate emotions, reduce stress, and find comfort in an unpredictable world.

The behavior becomes worth examining only when it’s compulsive, distressing, or interfering with your daily life. If you’re rewatching because you enjoy it, because it helps you relax, or because it brings you comfort—you’re in good company.

As one psychologist put it: “Rewatching familiar content is usually a healthy form of emotional regulation, not a symptom of any disorder”.

So go ahead—hit play on that familiar intro one more time. Your brain might just thank you for it.
