The Psychology of Money: Why Do We Spend More When We're in a Good Mood?

It would seem that when we are happy, we should be more rational.
But in practice, it is the opposite.
A good mood often makes us… financially weaker.
And this is not a coincidence, but a completely logical behavior of the brain.

1. Emotional uplift = less control

When we are in a good mood, the brain goes into a state of “everything is fine”.

In this mode, it lowers the level of alertness and stops looking for risks.

Happiness → turning off financial “brakes” → impulsive purchases.

This is similar to the effect of alcohol, only milder.

2. Reward for achievements
After a successful day or a pleasant event, we automatically want to “reward ourselves”:
— a cafe,
— new clothes,
— a small purchase,
— something that “I have long wanted”.

The problem is that rewards become a habit.
And then the brain starts looking for even the smallest reason to “treat ourselves”.

3. The illusion of financial stability
A good mood creates a feeling that everything is under control.
Even if the real financial situation is far from ideal.

We think:
“But then I’ll catch up”
“The next paycheck will solve everything”
“One small expense won’t change anything”

This illusion is the reason why people spend the most precisely when everything is good.

4. Psychology of “I can afford it”
When we are in a resource, the brain increases self-esteem → increases tolerance for spending.
Therefore, the thought arises:
“I am a good person today - I have the right to spend more.”

This is a very human, but dangerous belief.

5. Social factor: good mood = more communication
When we are happy, we meet more often, go to cafes, plan entertainment.
And this is almost always money.
Often, it is imperceptible small amounts that add up to large expenses.

How to avoid “happy spending”?
1. The 24-hour rule

When you want to buy something in a state of euphoria, pause.
After a day, 70% of desires disappear.

2. Budget for emotional purchases
Select a separate category:
“emotional spending — 10%.
You invest within the limit — everything is great.

3. The ritual of checking the balance before buying
One short opening of the application is the best antidote.

4. Replace the reward
Not a purchase, but:
— a walk
— a movie
— favorite music
— delicious coffee (the most budget-friendly reward)

5. Conscious pause
Ask yourself:
“Is this purchase for pleasure or for utility?”
In 50% of cases, it becomes clear that it is not necessary.

Conclusion

A good mood is a great resource, but it makes us less rational about money.
Understanding this mechanism allows you to maintain a balance:
enjoying life, but not harming your financial goals.
