Clench Your Way Out of Stress
The simple trick of squeezing the hand that you don’t use to write into a fist has been proven to help you keep calm and think rationally. Panicking under pressure seems to be caused by brain activity in the nondominant hemisphere, so distracting that side of the brain can stop the overthinking that leads to errors in judgment. Therefore, if you’re right-handed, you should clench your left fist and vice versa. Try it next time you’re in a stressful situation that requires accuracy and level-headedness.
