Brainwaves of varying frequencies are measured in your brain using a machine referred to as electroencephalogragh (EEG). The EEG machine used electrodes which are placed on special sites on your scalp so as to detect, measure and record electrical activity among them frequencies in your brain. Frequency refers to the number of times a wave recurs in one second. Top sleep frequencies are frequencies which are detected or are most useful for good night sleep.
Top sleep frequencies can be compared to those of a radio. If you do not accurately tune your radio, chances are the music or sound you listen to will have some noise in the background. Similarly, there are not enough top sleep frequencies being produced by your brain, sleep as well as mental performance will suffer. Sleep will also suffer if top sleep frequencies are excessive or difficult to access.
Top Sleep Frequencies: Waves
Here are some top sleep frequencies that you need to know about:
Delta Waves (0.1 to 3.5 Hz)
Delta waves represent the lowest top sleep frequencies detected by an EEG. It is mostly detected in deep sleep and is the most dominant wave among infants and children under the age of 1. No wonder infants spend most of their times sleeping! Delta waves are seen in the 3rd and 4th stage of sleep.
These waves are produced by the brain when it wants to reduce subconscious activity and eliminate or at least reduce physical activity. Delta top sleep frequencies can be used to induce drowsiness and deep relaxation states.
Theta (4-8 Hz)
The frequency is theta is a bit higher than that of delta waves. Theta waves are observed in the following brain activities:
These brain waves are also produced at high levels when are meditating or in a deep state of spiritual awareness. You may have noticed that theta waves are produced when you are in-between sleep and wakefulness. Theta waves are normal among children up to 13 years. In adults, these waves are only normal during sleep and in the states described above.
The brain is most resourceful when it is producing alpha waves. They enhance the ability of the brain to coordinate and also increase a deep sense of relaxation. When alpha waves are highest, you are more likely to accomplish different activities quickly and efficiently.
Beta (over 12 Hz)
These top sleep frequencies are associated with very fast activity. It is observed on both sides of the brain but mostly at the front. In most cases, it is considered normal when you are alert, active and when your eyes are open. It is the most active brain wave when you are thinking or making a critical decision.
Gamma (over 30Hz)
Gamma waves are produced when you are thinking or integrating very complicated thoughts. Of the frequencies, it is the only one which is produced by all part of your brain. Gamma waves are associated with good memory and increased ability to learn.
Increase Your Top Sleep Frequencies
As you can see, there are different top sleep frequencies produced by the brain. If you want to sleep deeply, then delta and theta frequencies are the best for you. During the day play music turns at alpha, beta and gamma frequencies so as to increase your level of alertness.
