Each brain wave has its own corresponding different brain consciousness state. It can also be said that different states of consciousness need different brain waves to best complete the work of the brain. If the brain can't have corresponding brain waves under certain circumstances, we are in trouble. For example, when you want to sleep, there are no Delta waves and Seta waves in your brain, which is insomnia. On the contrary, people who have the right brain waves at the right time are what people call geniuses.

A useful metaphor, we can regard the four brain waves of the brain as four gears of a car. Delta is in first gear, Sunda is in second gear, Alpha is in third gear, and Times him is in fourth gear. No gear is suitable for all driving conditions, and no brainwave condition is suitable for all life challenges. If a certain gear of the car can't be used, or we forget to use it, there is something wrong with the car. For example, if we start from the first gear and then directly shift to the fourth gear (omitting the second gear and the third gear), the fuel consumption of the car will increase greatly and the maintenance cost will be very expensive. So is the brain. Unfortunately, however, we see that too many people use their brains without the second and third gears (Zeta brainwaves and Alpha brainwaves), and the result of driving the brain is the inefficiency of the brain and the increase of medical expenses. How did this happen?

Let's give an example to describe the life of modern people. When a person is still in deep sleep in the morning (delta brainwave state), he is suddenly awakened by an alarm clock. There is no time to act immediately (double his brain wave state), and a tense, anxious and hurried day begins! ! ! Drink a cup of coffee to keep yourself awake (beta brainwave state). Caffeine can inhibit β brainwaves and α brainwaves and improve β brainwaves. Work under tension, stress or anxiety all day (double him, double him or double his brain waves) until he is exhausted at night, and then plunge into bed and start sleeping (directly enter the Delta brain wave state). There is no time for relaxation and drowsiness in a day (no time to enter the state of alpha brain waves and other brain waves). In modern life, too many people use their brains like this, and suddenly they forcibly enter the fourth gear directly from the first gear and return directly from the fourth gear to the first gear.

The rationality of the existence of alpha brainwaves is inherent in our human brain and is one of the basic states of the brain. However, the tension of modern life makes too many people forget to keep their brains in the state of alpha brain waves, so many people become victims of diseases caused by tension and anxiety. Tension and anxiety can reduce the body's immune ability. However, people with relatively more alpha brain waves have relatively less anxiety and nervousness, so their immune ability is relatively high. This is good for everyone.
