The secret of attractive people"s appeal revealed

Beauty and Health: Scientists Discover Link Between Attractiveness and Immunity

Researchers from Texas Christian University have revealed an intriguing biological pattern: a person's physical attractiveness is directly related to the state of their immune system. Science had previously established that people unconsciously choose partners with a pleasant scent, signaling good health. Now it turns out that appearance is also an important indicator: the stronger the immunity, the more attractive a person's face appears to others.

In the first part of the experiment, 159 students provided blood samples and participated in a photo session without makeup or accessories. Specialists evaluated the activity of their immune cells. In the second part, 492 participants ranked photos of the opposite sex according to attractiveness.

The results showed that people deemed most attractive had high levels of phagocytosis - the ability of immune cells to absorb harmful bacteria and viruses. Men also showed elevated levels of NK cells, which destroy infected and cancer cells. Interestingly, men preferred women with lower levels of NK cells, which, according to scientists, is related to hormonal background: high estrogen reduces NK cells, but can also be a sign of reduced fertility.

Researchers note that classic signs of attractiveness - clear skin, defined cheekbones, bright eyes, and full lips - have historically been associated with health, and not by coincidence. The human brain is essentially "programmed" to search for a partner with strong immunity.

"Attraction to beautiful people is not superficiality, but an evolutionary mechanism," explained lead study author Summer Mengelkoch in an interview with Daily Mail. However, she added that thanks to medical advances, partners can now be chosen not only by "biological signals" - the risk of deadly infections today is significantly lower than in the past.
