The Science Behind Why Kiss Sounds Make Us Cringe The wet, squelching sound of a passionate kiss on television makes many people instantly cringe and want to turn off the TV. While a kiss can be a beautiful sign of love between two people, the actual noise it makes is widely hated. If you find yourself shuddering, plugging your ears, or looking away during romantic movie scenes, science shows that you are not alone.
Our brains are hardwired to react poorly to these noises due to a mix of evolutionary survival skills, brain mix-ups, and psychological boundaries. 1. Evolution and the Disgust Reflex
Our brains have an ancient alarm system called the amygdala. This tiny area handles fear and survival instincts. For thousands of years, humans survived by staying away from things that could make them sick.
Wet, squelchy mouth noises sound a lot like bodily fluids, vomiting, or open wounds. When you hear a loud, wet kiss, your amygdala can misinterpret the sound as a warning sign of a disease or a pathogen. To protect you, your body instantly triggers a flash of disgust, causing you to pull back and cringe. 2. The Brain Mirroring Mix-Up
A major reason kiss sounds bother us has to do with how our brains copy the movements of others. A study published by the Newcastle University Auditory Cognition Group discovered that mouth sounds activate a specific “mirror system” in the human brain. Hate slurping or chewing sounds?
