Spring brings more sunlight, which affects hormone levels such as serotonin and dopamine. This can increase energy, optimism, and the desire for change. People sometimes reevaluate their lives and relationships when they feel more "alive" than in winter.
Social media also circulates the "April theory," where users claim that this month sees the highest number of breakups.
Spring and summer are often associated with new beginnings (e.g., vacations, weddings, travel), which can prompt people to reassess existing relationships and seek changes if they are unsatisfied.
Our mood is closely linked to the seasons. As symptoms of seasonal affective disorder begin to diminish, many people feel more motivated, sociable, and open to change. For some, this renewed energy helps them reconnect with their partner. For others, it highlights a disconnect they can no longer ignore.
Alongside spring cleaning at home, some people also experience a "cleaning" of their emotional life situation when they feel ready for a fresh start.
Some social media and dating app research shows increased activity in breakups and seeking new relationships during the spring months, particularly around March and April.
The most well-known analysis is by American psychologist Brian Dunn in 2018, which shows an increase in breakups and the search for new relationships in March and April.
