In our culture, normal human emotions like temporary sadness are often treated as disorders. Manipulative advertising, marketing and self-help industries claim happiness should be ours for the asking. Yet bad moods remain an essential part of the normal range of moods we regularly experience.
Despite the near-universal cult of happiness and unprecedented material wealth, happiness and life satisfaction in Western societies has not improved for decades.
It’s time to re-assess the role of bad moods in our lives. We should recognise they are a normal, and even a useful and adaptive part of being human, helping us cope with many everyday situations and challenges.
A short history of sadness
In earlier historical times, short spells of feeling sad or moody (known as mild dysphoria) have always been accepted as a normal part of everyday life. In fact, many of the greatest achievements of the human spirit deal with evoking, rehearsing and even cultivating negative feelings.
Greek tragedies exposed and trained audiences to accept and deal with inevitable misfortune as a normal part of human life. Shakespeare’s tragedies are classics because they echo this theme. And the works of many great artists such as Beethoven and Chopin in music, or Chekhov and Ibsen in literature explore the landscape of sadness, a theme long recognized as instructive and valuable.
Ancient philosophers have also believed accepting bad moods is essential to living a full life. Even hedonist philosophers like Epicurus recognized living well involves exercising wise judgement, restraint, self-control and accepting inevitable adversity.
Other philosophers like the stoics also highlighted the importance of learning to anticipate and accept misfortunes, such as loss, sorrow or injustice.
What is the point of sadness?
Psychologists who study how our feelings and behaviors have evolved over time maintain all our affective states (such as moods and emotions) have a useful role: they alert us to states of the world we need to respond to.
In fact, the range of human emotions includes many more negative than positive feelings. Negative emotions such as fear, anger, shame or disgust are helpful because they help us recognise, avoid and overcome threatening or dangerous situations.
But what is the point of sadness, perhaps the most common negative emotion, and one most practising psychologists deal with?
Intense and enduring sadness, such as depression, is obviously a serious and debilitating disorder. However, mild, temporary bad moods may serve an important and useful adaptive purpose, by helping us to cope with everyday challenges and difficult situations. They also act as a social signal that communicates disengagement, withdrawal from competition and provides a protective cover. When we appear sad or in a bad mood, people often are concerned and are inclined to help.
Some negative moods, such as melancholia and nostalgia (a longing for the past) may even be pleasant and seem to provide useful information to guide future plans and motivation.
Sadness can also enhance empathy, compassion, connectedness and moral and aesthetic sensibility. And sadness has long been a trigger for artistic creativity.
Recent scientific experiments document the benefits of mild bad moods, which often work as automatic, unconscious alarm signals, promoting a more attentive and detailed thinking style. In other words, bad moods help us to be more attentive and focused in difficult situations.
In contrast, positive mood (like feeling happy) typically serves as a signal indicating familiar and safe situations and results in a less detailed and attentive processing style.
Psychological benefits of sadness
There is now growing evidence that negative moods, like sadness, has psychological benefits.
To demonstrate this, researchers first manipulate people’s mood (by showing happy or sad films, for example), then measure changes in performance in various cognitive and behavioral tasks.
