You look at the love of your life and find that the passion has fizzled out. You no longer feel the blood rush to your brain or your heart thud in your chest and are at a loss to understand this. Well, help is at hand. Blame the "Love Molecule."
Italian researchers have found that the first year of romance is the best one since there is a high level of Nerve Growth Factor (NGF) that is released in the brain. The NGF is a protein and was found in high levels in the blood of 58 people who had just fallen in love than in those who had steady relationship for a long time. The Pavia University researchers also found that after the first year, the levels of this molecule dropped drastically thereby affecting the intensity of the romance. These levels were similar to those found in the people with long-term relationships.
The researchers have published their findings in the latest issue of the journal Psychoneuroendocrinology. They say that the link between falling madly in love and the higher levels of NGF was not all that clear, but it did have a significant effect on "social chemistry" between couples at the start of the romance.
The first rush of falling in love has been attributed to many things like a state of mind to harmony with nature, but this is the first time that a biochemical link has been found.
