When the brain works, it produces brain waves. There are four main states of brain waves recognized by the scientific community. Neuroscience and the International Brain Wave Society are divided into four categories according to the frequency of brain waves: α, β, θ and δ. Studies have found that the frequency of brain waves has a corresponding relationship with people's thinking and mental state:
Every cell in the human brain contains a huge electrochemical complex and a powerful microscopic data processing and transmission system. When the brain works, the movement of ions in nerve cells generates current, and 654.38+0.5 billion neurons (brain cells) in the brain constantly release micro-currents. Eeg can record the total current activity of the brain. The current activities of the brain have different shapes, including fast and slow, producing brain waves of various frequencies.
Alpha wave: When 8-14hz alpha wave is the dominant wave, people's consciousness is clear, but their body is relaxed, which provides a bridge between consciousness and subconscious. In this state, the body and mind consume the least energy and gain more energy than the brain, so the operation will be faster, smoother and sharper. Alpha wave is the best brain wave state for people to learn and think.
Beta wave: People above 14HZ are in the dominant state of beta wave most of the time when they are awake. With the increase of beta wave, the body gradually becomes nervous, thus reducing the ability of the immune system in the body. At this time, people's energy consumption intensifies and they are prone to fatigue. If they don't have enough rest, they will easily accumulate stress (this is a common problem of modern people). Appropriate β wave has a positive effect on attention improvement and cognitive behavior development.
θ wave: When the 4-8HZθ wave is the dominant wave, people's consciousness is interrupted, their body is deeply relaxed, and they are in a highly suggestive state of external information, that is, hypnotic state. θ wave is very helpful to trigger deep memory and strengthen long-term memory, so θ wave is called "the gate of memory and learning".
δ wave: When the δ wave of 0.4-4 Hz is the dominant wave, it is in deep sleep and unconscious state. People's sleep quality is directly related to δ wave. δ wave sleep is a dreamless deep sleep state. If you summon a state similar to δ wave when you have difficulty sleeping, you can quickly get rid of insomnia and enter a deep sleep. The pursuit of beauty sleep is this short but deep sleep.
