Scent can act as a powerful aphrodisiac
When it comes to attraction, one organ plays a vital role. No, not that one -- I’m talking about your shnoz. Because each person has a unique scent, we are biologically programmed to seek out a mate who has a different stink than we do.
Neuroscientist and psychologist Dr. Rachel Herz explains the effect of an assortment of immune system genes that physically manifest in body odor. Altogether, these genes are referred to as Major Histocompatibility Complex, or MHC, and this has a huge effect on how people respond to one another.
When a woman likes the way you (and your hoodie) smells, that’s her body’s way of acknowledging that your offspring would have healthy immune systems. This biological effect can be mimicked or enhanced by other scents, such as cologne.
Scent also has a huge effect on memory
When your girl wears your hoodie, it allows her to connect with you when you’re not around, which can be creepy or cute, depending on how you feel about the situation. Scent can trigger some seriously far away memories because of the way your brain is wired. All smells are processed by the olfactory bulb, which is directly connected to the amygdala, the center in your brain in charge of emotions, emotional behavior, and motivation.
