Why do we scream if we're scared? Ever wonder what causes such strange reactions? After all, if we're threatened by something, it's logical and safer to just quietly run away quickly. However, it's not that simple. The brain doesn't consider a scream to be a sound; it recognizes it primarily as a fear trigger. In this way, a person has a perfect defense mechanism. It is not primarily a signal for others, but for the brain🧠 But there is also a social meaning in screaming - it's how we warn everyone about danger. In the days when we were moving on 4 paws - it was incredibly important. (The animation shows the process of triggering the release of adrenaline from the adrenal glands.)
