Because when we have fallen in love with someone, we walk through the world with rose-colored glasses.

Before we look at being in love and love from a scientific and biochemical perspective, here are some symptoms that you can tell that you may be in love (keyword: love is blind).

What is love - This happens in your body and brain when you love 

These feelings and actions are signs of being in love:

  • Euphoria
  • Be happy
  • decreased concentration
  • Tendency to be distracted
  • thoughtless and passionate action
  • increased willingness to take risks
  • Attention drops
  • Focus and idealization of the swarm
  • Excitement and nervousness at thinking about the crush
  • anorexia
  • Motivation and increased drive
  • Food cravings

As you can see and maybe even feel at the moment, being in love can throw you off track and even interfere with your normal everyday life at times. The fact that your body goes crazy when you are in love is related to your hormones, which ride a roller coaster in your body. Let's take a closer look - now it's going to be less romantic too, I promise!


Falling in love: what happens in the brain and body?

When you're in love, the ventral tegmentum (VTA) near your brainstem becomes active and is part of the brain's reward system. The activity takes place in some of the so-called ApEn cells. These are cells that actually make the natural hormone dopamine and then pour it out into many regions of the brain. The reward system is well below your cognitive thought processes and below your emotions. Part of it is related to your desires, your motivation and concentration as well as desires.

You have probably heard the saying that love is a drug and is addicting. When falling in love is exactly the same region active as in a cocaine intoxication, the nucleus accumbens.1 In fact, many symptoms of addiction show up when falling in love, such as focus, obsession, desire for that person, distortion of reality and the willingness to take risks in winning the person over. Furthermore, romantic love has three main characteristics of an addiction: the tolerance limit (the desire for more), withdrawal and relapse.

But love is more than a brief intoxication - love holds you tight, makes you obsessed, because you just can't stop thinking about this person. In general, being in love is a beautiful state - when love is reciprocated. When feelings are rejected, the obsession can even worsen.

Falling in love with research: activity in the brain

In one experiment, people in love and people who were abandoned were sent to an MRI scanner. The researchers found activity in three brain regions which, by the way, are still active even after years of love, such as after 25 years.

These are the areas in the brain that deal with

  • intense romantic love,
  • the calculation of profit and loss
  • and deep connection to another person

are connected. If you are now unhappily in love and cannot achieve what you want, the reward system in the brain becomes active - i.e. the area for wishes, motivation, longing and concentration. If you now see a picture of the person you love, the area of ​​the brain that calculates profit and loss also becomes active. In this case you would calculate what you have lost and the nucleus accumbens will become active. This is also true if you are willing to take enormous risks. But the third area of ​​deep attachment is also active. When you are rejected, you are not just trapped in feelings of romantic love, but you also feel a deep bond with that person.

But romantic love and attraction can also activate the brain's opioid system - the same system that heroin and opioid pain relievers activate. This part of the brain is involved in “liking” something. In this regard, scientists suspected that the opioid system had evolved to help us make the best partner choices. This is because feelings are triggered that play a role in the reward when we see our potential partner.

Your reward system works at full speed when you are in love and you are full of energy and motivation, focused on your goal and determined that you risk everything to win this person over for you. Romantic love is a simple mating drive, not a sex drive. Romantic love enables you to focus your pairing energy on one partner at a time. This saves you energy and allows you to start the pairing process with this one person.2
