You know what they say when you meet someone special, everything else blurs but not that person. Same goes with whatever that person gives you. For example, flowers. The colors suddenly become bright and vivid. This is also connected to the dilation of pupils that happen when we are with someone special. When you look at someone you’re attracted to, the pupils naturally dilate because of something that happens in the nervous system.

Your sense of hearing becomes sharp

Do you notice how sharp your hearing can be when you talk to someone special? It’s like you can almost hear every whisper, every breath, every sigh that person makes whatever the location. Being in love makes you want to remember everything you listen to.

For some reason, there is a certain feeling of recognition when you smell your special someone whether they use perfume or it’s their natural odor. It makes you feel secure, calm and relaxed. We also go for someone with a particular smell that sends signals to our brain.

You tend to feel hot and get sweaty at strange times. It is also similar to when you feel the physical sensation of adrenaline rush. Palms are the most common areas to get sweaty.

They say love is a drug… a good drug! Researchers say that falling in love triggers a feeling that is the same as the feeling if you’re high on cocaine. It also makes you feel crazy or out of your mind. This has something to do with the chemicals in the brain.

Your voice changes pitch

According to a study published in 2011, people tend to change the tone of their voice whenever they speak to someone they love. Notice how softer and calmer you talk whenever you are in front of someone you like? Your tone is obviously different from when you speak to other people. Voice modulation is also triggered by getting attracted to a certain timbre of the sound of someone’s speaking voice. Females tend to go for someone with a manly voice, while males go for someone with a more feminine-sounding voice.
