What Happens to Your Body When You Fall in Love

Sexual attraction goes far beyond us simply thinking someone is nice-looking, and when our brain decides that for whatever reason we love someone, the body triggers a series of reactions particular to the situation that typically causes the initial feeling of joy and euphoria. Do you know what these reactions can be? There are some you definitely won't guess, so at we explain what happens to your body when you fall in love.

There are ways to show another we like them without exaggerating. One of the clearest is to use body language. We all know the typical signs of flirting, but we cannot control reactions that have to do with the way the body handles attraction to another person.

Sweating is a strategy that our bodies use to transmit attraction precisely because through sweat the other person can detect our pheromones and feel attracted to us. The palms, armpits and even the intimate area usually sweat when we find someone really attractive.

The first signal can give us away, but it can hardly be noticed: the pupils dilate. When we get a pleasant stimulus, such as seeing or talking to someone we like, our pupils dilate as a physiological reaction to the pleasure.

There are many gestures we can make when we like someone. One of the most common is to have our legs or feet point toward that person, especially when talking to him/her. This indicates that we have an unconscious reaction to face that person and give them our full attention. We also have a tendency to stand tall, chest out and stomach in, to expose a slimmer figure and more confidence.

A common reaction in women is touching or playing with the hair from nervousness, but it is also primitive flirtation, because our hair is an element of sensuality and attraction for them. Meanwhile when men approach a girl they like, they unconsciously put their thumbs in their belts in order to emphasize their genital area, a way to demonstrate their availability and virility.


Biting our lips, gliding our tongue along them, leaving our mouth a little open. It all appears to be part of a plan to seduce them, but it is actually all a reaction controlled by our body. When we are attracted to someone our mouth and throat dry out because we feel nervous being near that person. So we drink more liquids and have a tendency to play with our lips or clear our throats.


The most famous body signal of all is when someone we like comes over and we blush when talking to them or when they complement us. Our heart beats quickly and every little thing makes the blood vessels in our face dilate more, and we feel a rush of heat and end up with our cheeks the color of a tomato.


Also when we're around someone we love we can react with other subtle cues like to expose the neck or wrists, playing with our clothes, especially in the chest area (both men and women do), or slightly opening the legs in the case of girls, a subtle invitation to intimacy.


The chemicals in your body also take part in your reaction when you are in love. Dopamine, norepinephrine and adrenaline are substances that are released by your body when you're in love, creating a sensation of feeling good and unexpected happiness within.

On the other hand, our levels of serotonin lower when we are in love, which is why you may notice you have a lower level of concentration when doing your daily activities.
