Not just flowers and chocolate: How love affects your health

When thinking about Valentine's Day, flowers, chocolates, and romantic dinners usually come to mind. But behind these small gestures lies a significant impact on health. Recent studies show that high-quality social and romantic connections not only contribute to mental well-being but are also linked to better physical health.

According to a comprehensive report published by the World Health Organization (WHO) in 2025, loneliness and social isolation are not just unpleasant feelings, but actual health risk factors. The report indicates that approximately 871,000 people worldwide die each year from causes related to loneliness and social disconnection. Furthermore, loneliness is linked to an increased risk of heart disease, type 2 diabetes, depression, and anxiety.

The heart benefits from good connections

The American Heart Association (AHA) emphasizes that partners influence each other's health habits—for better or worse. Couples tend to adopt similar lifestyle habits, so mutual encouragement regarding physical activity, a balanced diet, sufficient sleep, and adherence to medical care can benefit the health of both partners.

At the same time, new studies have found that feelings of loneliness are linked to an increased risk of heart valve disease, even after accounting for known risk factors such as age, smoking, and underlying conditions. Researchers believe that reducing loneliness could be an additional goal for improving heart health.

Love is not just about romantic relationships

Experts emphasize that there is no need to be in a romantic relationship to enjoy the health benefits of human connection. Close relationships with family members, friends, or the community provide emotional support, reduce stress, and contribute to mental and physical health. In fact, the World Health Organization calls for "social connection" to be seen as an integral part of health, alongside physical and mental well-being.

So what can be done today?

In honor of Valentine's Day, experts recommend investing not only in gifts but also in quality time. A real conversation, going for a walk together, a home-cooked meal, or visiting an elderly family member—all of these contribute not only to the relationship but also to your health.

The message of the study is clear: love is not a medicine, but meaningful human connections are an integral part of a healthy lifestyle. Whether it is a partner, a close friend, or family, investing in relationships is an investment in your health.
