Oxytocin

"The "love hormone" oxytocin is responsible for some of the positive emotions associated with attraction and sexual desire."

"Oxytocin has two main physical functions: stimulating uterine contractions during labor and childbirth, and stimulating contractions of breast tissue to aid in lactation after childbirth."

"The physical affection shown between adults can cause oxytocin to be released, which can in turn make the bond between them stronger. Oxytocin is known as one of the happy hormones because it has such a positive effect on emotions and mood, so it's no wonder that it's often thought of in a positive light."

"When you hug or kiss a loved one, your pituitary gland releases oxytocin, which is especially important for pair bonding, like in romantic relationships, as it elevates your mood and makes you feel more "attached" to your romantic partner."

"In the brain, oxytocin works as a chemical messenger and plays an important role in many human behaviors, such as sexual arousal, recognition, trust, and romantic attachment. It also plays a role in mother-infant bonding."

"Oxytocin is sometimes called the "love hormone" or the "cuddle hormone" because it is released when people fall in love or hug. Oxytocin is also released during sexual activity and childbirth."

"Oxytocin is released by the body in response to various stimuli, such as during labor, breastfeeding, sexual activity, or even just simple things like touching or being touched."
