What science teaches us about happiness: 5 habits to transform your daily life

Is happiness a state of mind, a feeling that comes and goes? Modern psychology debunks this common misconception and proves that it's the very concrete result of a well-structured daily routine. Based on recent scientific research, researchers have identified five fundamental habits that help build lasting well-being.

According to science, here is the recipe for happiness that lasts over time:

Maintaining quality social relationships is, without a doubt, the most decisive factor. The Harvard Study of Adult Development, conducted over more than 80 years, demonstrates that the quality of our emotional connections influences fulfillment, health, and longevity more than wealth, professional success, or IQ. As a result, researchers have elevated “social well-being” to the status of a daily priority—a behavior essential for both physical and mental health.

Spending money to “buy back” time: another key lever in building lasting happiness. Researcher Ashley Whillans of Harvard Business School demonstrates that a chronic lack of time severely impacts mental health. Paying to free oneself from burdensome tasks and to outsource them thus brings far greater well-being than the purchase and accumulation of material goods.

Seeking psychological fulfillment through various challenges adds depth to one’s life. A 2022 study published in the Psychological Review also reveals that travel, voluntary discomfort, personal and creative challenges, as well as continuous learning (though sometimes demanding), make life more colorful, stimulating, and… memorable!

Spending (and not just money) on others rather than on oneself fosters subjective well-being. According to a 2023 systematic review, whether through gifts, purchases, direct assistance, or even volunteering, investing our resources for the benefit of others activates our reward circuits, strengthens our sense of purpose, and deepens our social connections—regardless of our income level.

Spending at least 120 minutes a week in nature is the final key to lasting happiness. A landmark 2019 study, published in Scientific Reports, indicates that this threshold—easily achievable through daily 20-minute walks—significantly improves health and mental well-being. According to the researchers, this habit should be considered a non-negotiable biological need.
