Lou 1 makes sense. I also added a better method-"meditation sleep method". Let's have a look! Brain waves control our emotions. When there are "alpha" brain waves, we are in a state of relaxing our vigilance. When there are "beta" brain waves, we are easily agitated, angry and nervous. When there are "θ" brain waves, we fall asleep easily. When delta brain waves appear, you will take a deep breath, your heart will slow down, your blood pressure and body temperature will drop, and you will enter a deep sleep state! The right medicine, we must correct brain waves, so that "θ" waves and "δ" waves appear! 1 is a good way to build a station, this is my way! Meditation sleep method: 1 First relax your limbs and lie flat on the bed! Take a deep breath and imagine yourself in weightlessness without any consciousness! Breathe out slowly, spit out all the unhappiness in your heart and let it go with the wind! In my mind, I repeatedly imagine myself as a wooden stick lying flat, unable to be unconscious until I enter the "θ" wave state! I read the above methods in a medical book. Because I can't find it on the internet, I only write it from my own memory. Please forgive me if there is any mistake!

Satisfied, please adopt.
