Ever notice that listening to breaking waves helps you feel relaxed? Why does this happen? According to otorhinolaryngologists (a MASSIVE name for an ear/nose/throat doctor), part of the secret lies in our brains perception of low frequency repetitive sounds. When the brain accurately predicts a rhythmic pattern, such as the periodic crashing of waves onto the shore, it releases "pleasure chemicals" like dopamine that are the same as those released during sex and when eating delicious food. This is why humans crave rhythm, whether through music or sounds from nature! So in conclusion: listening to the ocean is totally like having sex. Class dismissed.
