In everyday life, there are many actions that seem to be ingrained in our subconscious. And of course, it is also easily explained by science.

Cheating on your partner

There are many reasons to explain someone's infidelity, but according to human scientists there is also a gene of 'deception' in your DNA. They discovered a gene called RS3 334 , which is understood simply as a divorce gene . In a recent survey, both men and women were asked to fill out a detailed table of their marriages. Surprisingly, husbands with one or more RS3 334 genes score relatively low and often experience difficulties or feel unhappy with their marriage.

Hug

In life, there are quite a few actions that we ourselves often wonder why do so. Often, we often use hugging action as a means to express our feelings for others. But for scientists, the nature of hugging is in fact closely linked to the production of Oxytocin, a hormone that helps to build attraction and trust. It is also known as love Hormone, or chemical of love, that is secreted and governs the brain during sexual and emotional processes. This hormone is quite important in regulating a number of human actions and it can also be released through eye contact, generous gestures or like patting a dog.

Do not like strangers

Children are mostly afraid of contact with strangers, which is entirely explainable. Still the hormone Oxytocin, but in this case, it helps us feel more comfortable with our acquaintances, but for strangers it makes us feel disbelieving. There have been some specific studies on this issue. A group of people participated in inhaling oxytocin or placebo with similar functions and participating in a collective game. The group consists of members who know each other to show their cooperation, group activities are quite effective while the group of strangers is not like that. This can also be traced back to the ancestors of our ancestors, when fear and conflict between different tribes were quite intense.

Scratching and scratching action

In everyday life, we scratch a lot, but what benefit does this have? Scratching or more accurately we are having itching, a way for the body to remove harmful agents or skin objects. For example, an ant crawls on your leg, which can make you itchy, and you scratch it to remove it. But that is only a part, sometimes there are no bugs on the skin, but we still scratch to stop itching. Why? From the point of view of evolutionary theory, it is actually the fact that we eliminate all the harmful agents for our body. In fact, if there is no scratching reflex, then we will be in danger from many different threats.

Debate with yourself

For this example, you get a chocolate bar. On the one hand, you really want to eat it, but on the other hand gaining weight makes you nervous. You tell yourself: 'Okay, I'll eat this chocolate bar and go to the gym tomorrow.' So who are you actually negotiating with? Technically speaking, the other person is your brain. The severity of this 'debate' with each person is completely different. But from a scientific perspective, your brain just wants to lead you to become another person.

Action laugh

The act of laughing is actually a series of cheers and cries when people are excited or when they are excited about something. It can be said that laughter is one of the most basic actions in our lives. According to scientists, laughing is a communicative language that helps us express joy and enthusiasm, helping to bring people together . This also explains why when a person laughs, everyone around them will laugh at you. Besides, some studies also show that it is more difficult for people to laugh alone.

Feeling tired at night

Most people sleep at night and wake up in the morning. But what exactly controls this action?

The main answer is melatonin hormone . It helped to regulate the body's biological clock or sleep-wake cycle. In the morning, exposure to sunlight stimulates the body to release hormones that give us more energy to perform daily activities. When in the dark, the pineal gland releases melatonin to help us feel more sleepy.

Because the pineal gland cannot recognize artificial light, when we are in a dark room or a bright room, it also affects the body's biological clock.

Angry

Have you ever wondered why people are angry or 'out of control' ? Most when angry, everyone turns into a different person, every action is based on instinct and your brain can't control it. This comes from the amygdala , which is located in the center of the brain and is the place to handle emotional factors in humans. It is also the factor that causes aggression and when the area is compromised, uncontrolled behaviors will operate with much greater intensity. Especially those with trauma, tumors or birth defects in the amygdala area, will tend to act uncontrollably, which tends to be more violent than ordinary people.
