Humans have roughly 70,000 different thoughts each day. Most of the time, our brain is thinking forward, predicting and constantly guessing what will happen next, creating feelings of anxiety, fear, worry. Ernst Poppel, a German psychologist, and neuroscientist in his research found that our minds are only present for about 3 seconds at a time. Our mind could not also stay present because it's holding on to the past most of the time, creating negative feelings like sadness, grief, low mood, and doubt.
The best way to manage stress is first to understand how our body typically reacts to stress.
