You probably know, in a general way, that you enjoy humor. You know you like to laugh. You may have a favorite comedian, a friend who always cracks you up, a type of comedy that reliably makes you feel better. But if someone asked you to describe your humor life with any precision—how often you laugh in a day, what triggers it, who you are with when it happens, how your mood and body feel before and after—most of us would draw a blank. We experience humor the way we experience breathing: constantly, automatically, and almost entirely without conscious attention.

This chapter proposes that paying attention to humor—deliberately, systematically, and over time—can transform it from a pleasant accident into a genuine tool for mental health. The vehicle for this attention is the laughter log, also called a humor diary: a simple, structured practice of recording what makes you laugh and how you feel afterward. It is the humor equivalent of a food diary, a sleep log, or a gratitude journal—and, like all of those practices, its power lies not in the recording itself but in the awareness the recording creates.

The Evidence: Why Tracking Humor Works

The strongest evidence for humor logging comes from the University of Zurich, where researchers Sara Wellenzohn, René Proyer, and Willibald Ruch conducted a series of placebo-controlled studies testing what they called the “Three Funny Things” intervention. Modeled on Martin Seligman’s influential “Three Good Things” exercise from positive psychology, the Three Funny Things intervention asked participants to write down three amusing, entertaining, or funny things that happened to them each day for one week.

The results were striking. In a 2016 study with 632 adults, all five humor-based interventions the researchers tested enhanced happiness, and three of them—Three Funny Things, applying humor in daily life, and counting funny things—produced improvements that remained stable at the six-month follow-up. The effects on depression were also significant, though they were most pronounced immediately after the intervention period. In a follow-up study testing who benefits most, the researchers found that humor-based interventions were equally effective for people who already considered themselves humorous and those who did not—a crucial finding suggesting that you do not need to be a naturally funny person to benefit from paying attention to humor.

The mechanism appears to involve two processes working simultaneously. The first is an attentional shift: when you know you will be recording funny moments at the end of the day, you begin scanning your environment for them, which means you notice humor that would otherwise pass unregistered. The second is savoring: the act of writing down a funny experience recreates the amusement, producing a second dose of the positive emotions—the dopamine, the endorphins, the parasympathetic activation—that accompanied the original experience. You laugh twice: once when it happens, and once when you remember it.

This dual mechanism distinguishes humor logging from simply watching more comedy. Consuming humor is passive; logging humor is active. It requires you to notice, select, remember, and articulate what was funny—a set of cognitive operations that engages the same reappraisal circuits that make humor such an effective coping mechanism in the first place. You are not just experiencing humor. You are practicing the skill of finding it.

What a Laughter Log Can Reveal

People who keep humor diaries consistently for even a few weeks report several kinds of insight that surprised them.

Your Humor Fingerprint

Everyone’s humor profile is different, but most of us have never examined ours with any specificity. A laughter log reveals patterns you may never have noticed. You may discover that your funniest moments almost always involve the same person—a colleague, a child, a partner. You may find that physical comedy makes you laugh more than wordplay, or that absurdity amuses you more than satire. You may notice that you laugh more on certain days of the week, in certain environments, or at certain times of day. This is your humor fingerprint: the unique configuration of triggers, contexts, and companions that produces laughter in your particular life. Knowing it allows you to seek it out deliberately.

Your Emotional Baseline

A humor diary that includes brief mood ratings before and after laughter events creates a personal dataset about humor’s effects on your emotions. Over time, you can see whether humor consistently lifts your mood, whether certain types of humor are more effective than others, and whether the effects are lasting or fleeting. Some people discover that a single genuine laugh in the morning shifts the emotional tone of their entire day. Others find that humor’s effects are real but brief, better understood as a reset button than a permanent fix. Both discoveries are valuable, because they replace vague beliefs about humor (“laughing makes me feel better”) with specific, personal knowledge (“observational humor with my sister consistently moves my mood from a four to a seven, and the effect lasts about an hour”).

Your Humor Gaps

Perhaps the most important thing a laughter log reveals is the absence of laughter. If you commit to recording three funny moments each day and find, on a Tuesday evening, that you cannot think of a single one, that is information. It does not necessarily mean something is wrong—some days are simply not funny. But if the pattern persists for a week, two weeks, three weeks, it becomes a signal worth attending to. In her research on depression, Andrea Samson has shown that reduced humor appreciation is one of the earliest and most reliable indicators of declining mental health—sometimes appearing before other symptoms become clinically visible. A humor diary can serve as an early warning system, a canary in the coal mine of your emotional life.

Your Social Humor Map

Robin Dunbar’s research on laughter as a social bonding mechanism suggests that tracking who you laugh with is as revealing as tracking what you laugh at. A humor diary that notes the social context of laughter events creates a map of your most vitalizing relationships—the people who bring out the best in you, the contexts where connection comes most naturally. It can also reveal isolation: if your laughter log shows that you almost never laugh with anyone, or that your laughter is confined to screen-mediated experiences rather than face-to-face interaction, that is worth knowing. Laughter is a fundamentally social act, and a diary that captures its social dimension can guide you toward the relationships and environments where you are most fully alive.

How to Keep a Laughter Log

The practice is flexible, and the best format is the one you will actually use. What follows are three approaches, ranging from simple to comprehensive, along with guidance for adapting each to your needs.

Approach 1: The Three Funny Things (Minimal)

This is the approach with the strongest research support and the lowest barrier to entry. Every evening, write down three funny things that happened during your day. That is it. They do not need to be hilarious—a mildly amusing observation, a child’s unexpected comment, a dog doing something ridiculous, a typo that changed the meaning of an email. The only requirement is that each entry represents something that genuinely amused you, not something you think should have been funny.

Wellenzohn and colleagues found that this intervention was most effective when participants wrote about events from the current day rather than the past or future, suggesting that the practice works best when it captures fresh experience. They also found that participants who enjoyed the intervention showed the largest long-term gains—so if this feels tedious, give yourself permission to adjust the format. The goal is to notice humor, not to complete an assignment.

A Three Funny Things entry might look like this:

1. The barista misspelled my name as “Kevlar” on my coffee cup. I am now Kevlar. 2. My daughter asked if dogs have their own language, and then tried barking at the neighbor’s golden retriever to find out. The retriever just stared at her. 3. During a work call, someone’s cat walked across their keyboard and accidentally unmuted the entire team. Chaos.

Approach 2: The Laughter Log (Moderate)

This approach adds structure to the Three Funny Things by tracking context, type, and emotional impact. It is best suited for people who enjoy self-reflection and want to build a more detailed picture of their humor life. Each entry records what happened, who was involved, what type of humor it was, and a simple before-and-after mood rating.

The following template can be adapted for a journal, a spreadsheet, or a notes app:

Date/Time	What Happened	Who Was There	Humor Type	Mood Before → After (1–10)
Mon 9am	Colleague’s deadpan comment about the new email policy	Work team	Observational / affiliative	4 → 6
Mon 7pm	My kid’s drawing of our family where the cat is the biggest	Family	Unintentional / innocent	5 → 8

The “Humor Type” column is intentionally informal—you do not need to use Rod Martin’s precise categories, though you are welcome to. Common labels include observational, physical, absurd, self-deprecating, dark, wordplay, sarcastic, unintentional, situational, and insider. Over time, the pattern of labels reveals your humor fingerprint far more accurately than any questionnaire could.

Approach 3: The Comprehensive Humor Diary (Deep Dive)

This approach is designed for readers who want to use humor tracking as a genuine tool for self-understanding. It is particularly useful for people working with a therapist, in a recovery program, or navigating a period of emotional difficulty. In addition to the elements in Approach 2, the comprehensive diary adds reflective questions:

What made this funny to me? Was it the surprise? The recognition? The incongruity? The timing? The shared context? Understanding why something is funny to you specifically is a form of self-knowledge that most people never develop.

What was my body doing? Did I laugh out loud? Smile? Snort? Feel warmth in my chest? This tracks the physiological dimension of humor—the vagal activation, the muscle relaxation, the endorphin release that we explored in the neuroscience chapters.

How long did the effect last? Did the amusement fade in seconds, or did I return to it throughout the day? Did I share it with anyone else? Humor that gets retold has a longer psychological half-life than humor that stays private.

Was this humor I found, humor I created, or humor that found me? This distinction matters because, as the chapter on Creating vs. Consuming Humor showed, actively generating humor has deeper psychological benefits than passively receiving it. Over time, this question reveals the ratio of active to passive humor in your life—and whether you might benefit from shifting the balance.

Is there anything this humor helped me cope with? Sometimes a laugh is just a laugh. But sometimes humor serves a coping function—it reframes an anxiety, softens a disappointment, transforms an awkward situation into a shared joke. Tracking this function over time reveals how much you already use humor as a coping tool, even without consciously thinking of it that way.

Weekly and Monthly Reviews

The daily practice creates raw material. The real insight comes from reviewing it periodically.

The Weekly Check-In

At the end of each week, spend ten minutes reviewing your entries and asking yourself a few questions. What was the funniest moment of the week? Was it humor you found, created, or received? Who were you with during your best laughter moments? Were there days when humor was notably absent? If so, what else was happening on those days? Is there a type of humor that showed up more than others?

The weekly check-in is where patterns begin to emerge. You might notice that your humor is concentrated on weekends, suggesting that your work environment could benefit from more lightness. You might find that your partner or a specific friend appears in your entries far more than anyone else, revealing the central role they play in your emotional life. You might observe that physical comedy entries are associated with bigger mood shifts than clever wordplay, or that absurd humor lifts you out of low moods more effectively than observational humor.

The Monthly Reflection

Once a month, look at the broader arc. Is your humor life expanding or contracting? Are you laughing more or less than you were four weeks ago? Have new humor sources entered your life? Has the balance between humor found, humor created, and humor received shifted? Most importantly: how does your humor life correlate with your overall mental health this month?

This is where the humor diary becomes genuinely therapeutic. If you can see that weeks with more laughter entries correspond to weeks of better mood, more social connection, and greater resilience, you have personal evidence—not just research findings, but data from your own life—that humor matters to your well-being. And if you can see that weeks with fewer entries correspond to declining mood, increased isolation, or rising anxiety, you have an early warning system that can prompt you to seek support before a difficult period becomes a crisis.

Humor Diary Variations

The formats above can be adapted for different needs and contexts.

The Couples Humor Diary

Jeffrey Hall’s research shows that shared humor is one of the strongest predictors of relationship satisfaction. A couples humor diary, kept jointly or in parallel, tracks the moments of shared laughter in a relationship. Each partner records what made them laugh together, and the couple reviews the entries weekly. This practice does three things: it increases attention to the positive moments in the relationship (which is itself a well-established intervention for relationship satisfaction), it creates a shared archive of good times that can be revisited during difficult periods, and it reveals the specific humor dynamics of the relationship—what makes this particular pair laugh, and how that laughter functions in their bond.

The Therapy Companion Diary

For readers in therapy, a humor diary can serve as a companion to clinical work. Entries can be brought into sessions as material for discussion: the humor that helped you cope with a stressor, the joke that masked pain, the laughter that signaled genuine healing, the absence of humor that indicated a worsening of symptoms. Therapists trained in cognitive-behavioral approaches may find humor diary entries particularly useful as examples of spontaneous cognitive reappraisal—real-time evidence of the client’s capacity to shift perspective on difficult experiences.

The Gratitude-Humor Hybrid

Some practitioners combine the Three Funny Things practice with the more widely studied Three Good Things gratitude practice, recording both each evening. Research suggests that these practices work through overlapping but distinct mechanisms—gratitude shifts attention toward things that are good, while humor shifts attention toward things that are absurd, incongruent, or surprising. Together, they train two complementary forms of positive attention: appreciation and amusement. The hybrid format also provides a natural comparison: on days when you can easily list good things but struggle to find funny ones, or vice versa, the discrepancy itself becomes data about your emotional state.

The Family Humor Board

For families with children, a shared humor board—a whiteboard, a corkboard, a shared digital document—where family members post the funniest thing that happened to them each day creates a communal version of the humor diary. The 2024 Penn State study on humor in parenting found that sixty-three percent of adults who reported having an excellent relationship with their parents described those parents as using humor frequently. A family humor board does not just track laughter; it normalizes it as a family value, teaches children to notice and articulate what amuses them, and creates a daily ritual of shared attention to the lighter side of family life.

The Recovery Humor Diary

For people recovering from depression, grief, trauma, or a mental health crisis, a humor diary can track the return of humor as a sign of healing. As Gary Gulman described after his hospitalization for depression, the capacity for humor comes back—but it comes back gradually, unevenly, and sometimes so quietly that you miss it unless you are looking. A recovery humor diary does not require three entries every day. It requires only one question: did anything strike me as even slightly amusing today? A single “yes” in a week of “nos” is not a failure. It is evidence that the capacity for humor is still there, still functioning, still waiting for the conditions to improve enough for it to re-emerge.

Common Questions and Concerns

What if I am not a funny person?

The humor diary is not about being funny. It is about noticing humor. These are entirely different skills. You do not have to generate the humor that goes in your diary; you just have to recognize it when it shows up. Wellenzohn and colleagues specifically tested whether humor-based interventions work differently for people with high versus low senses of humor, and found that they were equally effective for both groups. You do not need to be funny to benefit from paying attention to what is funny.

What if I cannot find three funny things?

First, lower the bar. A funny thing does not need to be hilarious. A slight smile, a moment of wry recognition, a small absurdity counts. Second, look in unexpected places: the behavior of animals, the unintentional humor of bureaucracy, children’s logic, the gap between how your day was supposed to go and how it actually went. Third, if you genuinely cannot find a single moment of amusement across an entire day, that is still a valid diary entry. Write: “Nothing struck me as funny today.” Then note how you feel. As one participant on the Greater Good Science Center’s Three Funny Things page observed: the practice can serve as a measure of how you are doing. If you can find funny things, you are probably okay. If you cannot, some adjustment might be helpful.

How long should I keep the diary?

The research suggests that even one week of consistent Three Funny Things recording produces measurable effects on happiness, with some benefits persisting for up to six months. However, like any awareness practice, the benefits are greatest when the practice is sustained. Think of it less as an intervention with a set duration and more as a habit—something you do most days, not because a study told you to, but because it makes your life slightly better. If the nightly writing becomes tedious, switch to a weekly format: review your week and record the three funniest moments. If writing feels too effortful, use voice memos. The format matters less than the attention.

Will this work if I have depression or anxiety?

The research evidence is promising but nuanced. Wellenzohn and colleagues found that humor-based interventions produced short-term improvements in depression symptoms in all participants, though the effects on depression were less durable than the effects on happiness. For people with clinical depression, the humor diary is best understood as a complement to treatment, not a substitute for it. It can be a valuable part of behavioral activation—the evidence-based practice of deliberately engaging in activities that produce positive emotions, even when depression makes them feel effortful or pointless. If you are managing a mental health condition, consider sharing your humor diary practice with your therapist. It may reveal patterns, strengths, and vulnerabilities that enrich your clinical work together.

A Sample Week

To make the practice concrete, here is what a week of moderate-format laughter logging might look like for an imaginary diarist:

Day	What Happened	With Whom	Type	Mood Shift
Monday	Autocorrect changed “meeting” to “mating” in an email to my boss. Caught it just in time.	Alone	Situational	3 → 5
Tuesday	My toddler insisted on wearing rain boots to bed. Negotiated for one boot. She accepted.	Family	Innocent	5 → 8
Wednesday	Nothing struck me as funny today. Rough day at work. Headache.	—	—	3 → 3
Thursday	Friend texted a photo of her cat sitting in a salad bowl with the caption “Julius Seize-her.”	Friend (text)	Wordplay / visual	4 → 6
Friday	During a presentation, my slide showed the wrong graph. I said “That one’s aspirational.” Room laughed.	Colleagues	Self-enhancing	5 → 7
Saturday	Watched a comedian’s bit about grocery store self-checkout. Recognized every observation.	Partner	Observational	6 → 8
Sunday	Played a board game. My mom accused my dad of cheating. He had been. Drama ensued.	Family	Situational / affiliative	7 → 9

Even this brief sample reveals patterns. The diarist’s biggest mood shifts happen with family and friends. Wednesday’s blank entry coincides with a physically and emotionally difficult day. The most effective humor moments are social, not solitary. And Friday’s entry—where the diarist created humor spontaneously under pressure and successfully landed it—produced a notable mood boost, consistent with the research on creating versus consuming humor. A week of entries is a snapshot. A month creates a portrait. A season creates a map of your emotional landscape.

The Deeper Practice: From Logging to Understanding

At its simplest, a humor diary is a record. At its deepest, it is a form of self-knowledge.

The practice asks you to do something that our culture rarely encourages: to take humor seriously. Not to analyze the joy out of it, but to treat it as information—real, specific, personal information about who you are, what you need, and how you are doing. Your laughter reveals your values, because you laugh hardest at the things that matter most to you, seen from an unexpected angle. Your humor reveals your relationships, because the people who make you laugh are the people who see you most clearly. And the absence of your laughter reveals your pain, because humor is often the first capacity to go when we are struggling and the last to fully return.

Victor Frankl observed that humor was one of the soul’s weapons in the fight for self-preservation. A laughter log is a way of taking inventory of your armory. It does not give you weapons you do not have. It shows you the ones you do.

Getting Started

You do not need to buy a special journal. You do not need an app, though several exist. You do not need to write beautifully or in complete sentences. You need only this:

Tonight, before you go to sleep, ask yourself: what was the funniest thing that happened today?

Write it down.

Tomorrow, do it again.

That is the entire practice. Everything else—the templates, the weekly reviews, the mood ratings, the reflective questions—is optional enhancement. The foundation is simple: notice, record, repeat. The humor is already happening. The diary just helps you see it.
