Please mind that it is better to perform the first five exercises with your eyes closed.
A Simple Brain Warm-Up Routine
Set yourself to work: be mindful of your breathing and make ten calm inhalations and exhalations.
Count out loud from 1 to 100, and in reverse order.
Imagine a circle of pink or green color, then turn it into a ball, and after it, imagine a tetrahedron, cube, and trapeze.
Come up with one word for each of the letters of the alphabet in order. The word must be a rarely used one. For example, from asphyxia to zoochemistry.
Visualize yourself in detail as if you were looking at yourself from a distance. Visualize where and how you are sitting now, what you are wearing, what facial expression you are having right now.
Now, pick a memory and focus on it, trying to recall it in detail. It could be a view of your country house, the clothes you were wearing at your sister’s wedding, your workplace, etc.
Take a short text (2-3 paragraphs) and read it back to front.
Rewrite the same text with your left hand (or with your right hand if you are left-handed). If you know any foreign language (even at a basic level), you can also translate the same text into another language, using a dictionary.
Following some of these simple brain warm-up exercises, you will give your brain a good workout and make it easier for yourself to start the activities that require your attention, concentration, and productivity.
