Consumer behavior is a fascinating field that combines psychology, neuroscience and economics to understand why and how people make purchasing decisions. One of the most intriguing areas of this field is the study of how what we consume can influence the purchase decision. Among the most common and accessible are coffee and tea, beverages that are part of the daily routine of millions of people around the world. But did you know that drinking coffee or tea before shopping favors impulse buying? This phenomenon has been the subject of several recent studies and offers a fascinating insight into how our choices can be shaped by something as simple as a cup of coffee.
Caffeine, the active component in coffee and tea, is a stimulant that affects the central nervous system. Consuming caffeine increases the release of neurotransmitters such as dopamine and norepinephrine. These neurotransmitters are associated with alertness, concentration and pleasure. When released in increased amounts, they can improve our mood and make us feel more energetic and optimistic. This increase in mood and energy can lead us to behave more impulsively. In the context of shopping, this means that we are more likely to make unplanned purchases. Thus, we may give in to temptations that we might otherwise resist.
The neuroscience of consumption also tells us that caffeine can influence the perception of risk and reward
When we are under the effects of caffeine, our risk assessments are altered. Therefore, we tend to underestimate the potential dangers of our decisions. This, combined with an increased perception of immediate reward, can lead us to spend more money and make less rational purchasing decisions. This effect is particularly strong in shopping environments that are designed to maximize the attractiveness of products. For example, shopping malls and online stores with their visually appealing marketing strategies and limited-time offers.

Drinking coffee or tea before buying promotes impulse buying
In addition, caffeine can reduce our capacity for self-control. Self-control is fundamental to rational decision-making, as it helps us consider the long-term consequences of our actions. However, when self-control is compromised, we are more prone to get carried away by momentary impulses. In a store, this can mean the difference between buying only what we need and walking out with a cart full of extra items.
Neuroscience research also suggests that the environment in which we consume coffee or tea can amplify these effects. For example, having a cup of coffee in a social setting, such as a coffee shop, can further increase feelings of well-being and reduce inhibitions. This in turn can translate into more impulsive buying behavior.
In short, drinking coffee or tea before shopping can lead to a significant increase in impulse buying behavior. This is due to how caffeine affects our central nervous system, altering our mood, risk perception and capacity for self-control.
