Have you ever imagined winning the lottery, becoming financially free and living happily ever after? Research shows that kind of happiness may be far more short-lived than you think.

Studies have found that many lottery winners stay happier only for a while; afterwards their happiness may fall back to where it was before they won, or even lower.

What is hedonic adaptation?

American social psychologist Philip Brickman studied how major life events affect happiness, focusing on lottery winners and people who had been paralyzed.

He made an important discovery:
happiness adapts to major changes over time and gradually returns to a baseline.
He called this survival mechanism “hedonic adaptation.”

The study: happiness among lottery winners and paralyzed accident victims

Method

The researchers divided participants into three groups:
1. Lottery winners: people who had recently won a large prize.
2. Paralysis patients: people paralyzed after an accident.
3. A control group: ordinary people who had experienced neither extreme.

They surveyed all three groups on:
• their self-reported current happiness
• how much they enjoyed small everyday things
• their outlook and expectations for the future

Findings

Lottery winners' happiness

At the moment of winning, they were indeed happier than ordinary people — but they got less satisfaction than others from small everyday things. Activities like eating with family, exercising or going for a walk felt noticeably less enjoyable.

Paralysis patients' happiness recovers

Right after the injury, their happiness was clearly lower than average. But over time — after about a year — it gradually rose back close to normal. Some even found it easier to enjoy small things in daily life, showing strong adaptability and resilience in the face of adversity.

The control group stayed steady

Their happiness was stable, with no obvious ups and downs.

Conclusions

1. We adapt to both happiness and pain

Whether it's something wonderful like winning the lottery or something devastating like paralysis, the effect on happiness is temporary. Happiness doesn't stay high or low forever; the mind adjusts itself and eventually returns to a stable baseline.

2. Marginal happiness diminishes

Lottery winners had noticeably fewer sources of everyday joy. After winning, their expectations for life rose, which lowered their satisfaction with small things. The happiness wealth brings doesn't grow in a straight line; it gradually diminishes.

3. We adapt to adversity remarkably well

Even after something as extreme as paralysis, people could still find happiness in small everyday things. After all, once you've been through that, what storm could knock you down?

Hedonic adaptation in everyday life

The study shows that major events, good or bad, affect our happiness only temporarily. So how does this show up in daily life?

Examples are everywhere:
a new relationship, a new phone, a promotion, a raise, a new car, a new home, a trip, a great meal.

All of these bring happiness at first, but as time passes the feeling fades.

If hedonic adaptation can't be avoided, how can we make our happiness last longer?

The next article will look at how to fight hedonic adaptation.
