Quote by Dimitris Xygalatas

“Stress is a survival mechanism that serves an obvious evolutionary function. When we are anxious, our autonomic nervous system releases a cascade of chemicals (stress hormones), which give our body instructions on how to prepare to face danger. Our heart beats faster to pump more blood to the muscles, and our breathing becomes heavier to provide us with more oxygen. Muscles tense up to protect us from injury and to facilitate fighting or running. Sweating helps cool the body down. Our attention increases, and our reflexes become sharper, keeping us alert. Stress acts as motivation, helping us to focus on our goals and rise to meet our challenges, whether those involve studying for an exam, flying a fighter jet or scoring that match-winning goal. In short, stress serves a purpose. The problem, however, is that beyond certain threshold stress ceases to be useful.”
