That “connection” we sometimes feel with someone—even when nothing happens—has a biological and psychological basis.
Research in evolutionary biology shows that the body can detect chemical signals linked to genetic compatibility. Through body odor, the brain perceives differences in the immune system (MHC), and these variations can generate unconscious attraction.
From an evolutionary perspective, a different genetic combination would imply greater diversity and, therefore, a biological advantage.
Physiological synchrony also plays a role. Studies published in Nature Human Behaviour demonstrated that when two people are attracted to each other, their heart rates and breathing tend to align even without physical contact.
The body interprets this synchrony as a connection and activates the same brain circuits related to reward and anticipation.
Feeling that “energy” doesn’t always mean real compatibility. Sometimes it stems from emotions, past experiences, or simply personal interpretations. Biology can play a role, but it doesn’t determine human behavior.

Falling in love is easy, loving is a bit more difficult
The experience of romantic love goes through different stages and is experienced in different ways. It can range from love at first sight to a deeper assimilation that takes months, even years, to reach maturity.
In real life, instant love, what we call love at first sight, is the exception, not the rule. In this regard, it’s worth asking ourselves the following question: Is being in love the same as loving? It’s common to confuse some emotional and psychological states. As is the case with love and being in love.
These two emotions are undoubtedly very similar, but they are not the same. Therefore, it’s necessary to distinguish between loving and being in love. If there’s confusion about these, you can’t make the best decisions for a life as a couple.
