Aegean Sea Sleep Center - Sleeping Science (2)

Sleep state refers to the form that a person exhibits during sleep, as opposed to an awake state. There are four stages of sleep, namely: falling asleep, sleeping lightly, sleeping deeply, and continuing deep sleep. The sleep process of each cycle can be divided into four sleep stages from shallow to deep.
Falling into sleep (alpha wave phase)
The first stage (or the first period): the stage of falling asleep. Starting from drowsiness, gradually falling asleep and no longer staying awakened. At this time, the breathing slows down, the muscle tension drops, and the body relaxes slightly. At this time, it is a state of first sleep, and the sleeper is more likely to be awakened by external sounds or touches.
Shallow sleep stage (beta wave stage)
The second stage (or second stage): a shallow sleep stage, or a mild sleep stage. At this stage, the sleep is a light sleep or a mild to moderate sleep state, and the sleeper is not easily awakened. At this time, the muscle is further relaxed, and the EEG shows a fusiform sleep wave.
Deep sleep stage (γ wave stage)
The third stage (or the third stage): deep sleep stage, when the sleeper enters a deep sleep state, the muscle tension disappears, the muscles are fully relaxed, the sensory function is further reduced, and it is more difficult to be awakened.
Continue the fourth stage of the deep sleep stage (or the fourth stage of the delta wave stage): continue the deep sleep stage, this stage is the extension of the third stage, but not every sleeper can reach this stage, not every sleep cycle This can be achieved at this stage. Some people do not have enough sleep to reach this stage, or only have a short period of third and fourth stages of sleep.
Scientific research shows that the process of human sleep and dreaming mostly occurs in the fourth stage. Because of the stage of dreaming, human beings are often accompanied by the stage of eyeball rotation. Therefore, the fourth stage is also called “rapid eye movement stage” and the fourth stage of sleep time. The length of sleep determines the quality of sleep and the formation of long-term memory.
Using a mattress made of chemical fiber fabric, the human body will generate a large amount of static electricity during sleep, which interferes with the micro-current in the brain of the sleeping brain, making it difficult for sleepers to enter the third and fourth stages of sleep, making the sleeper second. Days produce fatigue, memory loss, and reduced working conditions.
In contrast, the use of 100% pure natural Egyptian long-staple cotton fabric can effectively avoid the generation of static electricity, and the cotton skin's skin-friendly, moisture-absorbing and breathable properties are very good, and a comfortable sleeping environment can effectively extend humanity. The sleep time of the third and fourth stages is the second day of sleep and the improvement of memory.
