In the past, many people believed that ‘love’ came from the heart. Because every time you feel love heart often beats fast And every time I’m broken-hearted The heart hurts more than any other part.
but in the latter era when people believed in science make me realize that it’s true Love comes from the brain, not the heart, because the brain is the center that controls thoughts, emotions, feelings, and expressions. While the heart only works to pump blood to the body according to the brain’s command.
When love is proven where it comes from So we would like to invite you to understand love. from the start of love to heartbreak in terms that can be easily explained with science
#1 Start falling in love
When you see that person’s face and your heart flutters, your cheeks turn red, or you blush until you can’t stand your balance, it’s called ‘falling in love’, which is caused by the hypothalamus brain. (Hypothalamus) produces Dopamine (Dopamine) come out
Dopamine is an important chemical that is released after a person feels satisfied. or love with something It is also a precursor of hormones. Epinephrine (Epinephrine) or adrenaline (Adrenaline) Therefore, when hormones are released Will cause the body to be excited and excited until the heart and other organs do not work properly, such as being embarrassed until your heart beats fast when meeting someone who matches your specification in real life Or meet your favorite idol on TV
The symptoms of falling in love that tend to cause people to accidentally act weird without knowing it, such as accidentally smiling, drooping, messing with their hair, etc., are caused by hormones. Serotonin (Serotonin) which serves to transmit signals between nerve cells in the brain and control emotions, feelings, and muscle function
#2 Falling in love over and over again with the same person and during pro
In addition to falling in love Dopamine and serotonin are also involved in the reward-seeking process. and happiness for oneself also known as ‘Reward Circuit’ which is an instinct to live normally of living beings Because when you reward yourself, both hormones will be released. make happy There is a mania, obsession or so-called love frenzy. Therefore, it is not strange that when falling in love We tend to put ourselves where he exists, trying to make up stories (on purpose), chance upon, or repeatedly following his work. To fill happiness every day
However, dopamine has a limited range of action. depends on living and environment of each individual making moments of mad love or as many people call ‘promotion period’ of each couple is different Some pairs may last only 3-6 months, while others may last for years.
#3 Binding after promotion ends
Even if love enters the end of the promotion But it’s not that every couple must be out of love. and always breaking up because of falling in love can turn into a bond which is a long term deep relationship
Binding is caused by two key hormones:
1. Oxytocin (Oxytocin) It’s released during close contact, such as holding hands, hugging, kissing, and having sex. which stimulates feelings of satisfaction and a sense of security to people as well One reason is because Oxytocin can be found in the reproductive organs.
2. vasopressin (Vasopressin) affecting mood and the desire to live together In a study in rats, it was found that Male rats receiving vasopressin have defensive behavior and spending time with the female than the group of males who did not receive hormones
#4 Crazy in love until blind
The symptom that love makes people blind It can be explained by science as well. Because even though the hormones that cause love will make people happy but if there is too much It can also cause negative effects, such as too much dopamine and oxytocin. May cause people to be anxious until they lose their consciousness in analytical thinking. and jealousy or unreasonably aggressive
#5 Broken heart
for the doubt that When love comes from the brain Why does it hurt when breaking up in the heart, not the brain?
That’s because When heartbroken in love, we experience sadness, stress, and anxiety, just like any other physical emergency. causes the adrenal glands to secrete hormones Cortisol (Cortisol) and adrenaline comes out automatically To help stimulate the heart to pump blood to the body normally. But what’s different is that in heartbreak, the body doesn’t need those hormones like in an emergency. So it tends to cause too much hormone in the body. until the heart is working hard and cause pain
The heartbreak symptoms may become more severe and become ‘Broken Heart Syndrome’ myocardial infarction And can die, so if the heart hurts until it is unbearable Don’t wait to see a doctor.
Science and Love 101: When Love Comes from the Brain, Not the Heart It’s just a part of the story of love. that can only be explained by science Because before we feel loved until we fall out of love, there are many complications.
