There is a chemical chain of reaction triggered in our bodies ultimately . Vasopressin is termed as an important hormone to promote long-lasting relationships. Falling in love can make you feel all sorts of crazy and wonderful things. "By producing more of these hormones, your brain is effectively There's a lot of empathy in relationships where couples are deeply bonded together. Known as the love hormone, oxytocin influences social behavior, emotion, and sociability. Oxytocin is produced in the hypothalamus, a part of the brain. Find out more about oxytocin's complex role in relationships.

Lust Lust is said to be the initial stage of getting involved with love. The feel of lust is basically backed up or instigated by the sexual hormones within the body. Limbic processes in the brain in response to lust have health-promoting and stress-reducing potential. In addition, lust, love, and pleasure ensure the endurance of mankind through mating. The mating process is a discrete interrelated process initiating attraction.

Attraction Second stage of acquiring love is attraction. This phase is said to be one of the beautiful moments of life. This is the phase when a person actually starts to feel the love. His or her impatience for attracting somebody leads to excitement, and the individual is left with no other option but to only think about that specific person.

The three sub-stages of attraction are adrenaline, dopamine, and serotonin. During labor, oxytocin increases uterine motility, causing contractions in the muscles of the uterus, or womb. As the cervix and vagina start to widen for labor, oxytocin is released. This widening increases as further contractions occur. Oxytocin also has social functions.

It impacts bonding behavior, the creation of group memories, social recognition, and other social functions. Oxytocin as a drug Oxytocin is used as a prescription drug under the brand name Pitocin.

Under medical supervision, an oxytocin injection is sometimes used to start birth contractions or strengthen them during labor, and it helps reduce bleeding after delivery. Side effects include a rapid heartbeat and unusual bleeding.

If too much oxytocin is delivered too rapidly, it can lead to a rupture of the uterus. Oxytocin can also be given to make the uterus contract and control bleeding after a delivery or a termination.

It can be used medically to induce a termination or complete a miscarriage.

Love, Actually: The science behind lust, attraction, and companionship - Science in the News

Inresearchers reported that people in the first stages of romantic attachment had higher levels of oxytocin, compared with non-attached single people. These levels persisted for at least 6 months. Sexual activity has been found to stimulate the release of oxytocin, and it appears to have a role in erection and orgasm. The reason for this is not fully understood, but, in women, it may be that the increased uterine motility may help sperm to reach their destination.

Love can be distilled into three categories: Though there are overlaps and subtleties to each, each type is characterized by its own set of hormones. Testosterone and estrogen drive lust; dopamine, norepinephrine, and serotonin create attraction; and oxytocin and vasopressin mediate attachment.

Love and the Brain

The evolutionary basis for this stems from our need to reproduce, a need shared among all living things. Through reproduction, organisms pass on their genes, and thus contribute to the perpetuation of their species.

The hypothalamus of the brain plays a big role in this, stimulating the production of the sex hormones testosterone and estrogen from the testes and ovaries Figure 1. As it turns out, testosterone increases libido in just about everyone.

The effects are less pronounced with estrogen, but some women report being more sexually motivated around the time they ovulate, when estrogen levels are highest. The testes and ovaries secrete the sex hormones testosterone and estrogen, driving sexual desire.

Dopamine, oxytocin, and vasopressin are all made in the hypothalamus, a region of the brain that controls many vital functions as well as emotion.

Several of the regions of the brain that affect love. Lust and attraction shut off the prefrontal cortex of the brain, which includes rational behavior.

Love is its Own Reward Meanwhile, attraction seems to be a distinct, though closely related, phenomenon. While we can certainly lust for someone we are attracted to, and vice versa, one can happen without the other.

In this case, these things include spending time with loved ones and having sex. High levels of dopamine and a related hormone, norepinephrine, are released during attraction. Interestingly, people who suffer from obsessive-compulsive disorder also have low levels of serotonin, leading scientists to speculate that this is what underlies the overpowering infatuation that characterizes the beginning stages of love.

The Friend Zone Last but not least, attachment is the predominant factor in long-term relationships. While lust and attraction are pretty much exclusive to romantic entanglements, attachment mediates friendships, parent-infant bonding, social cordiality, and many other intimacies as well.
