Meditation and Lower Frequency Brain Waves Meditation may also enable us to get to a deeper level of sleep and wake up more energized, which may be due to an increase in lower frequency brain waves. As we go from being awake to asleep, our brain goes through different brain waves. Beta waves are one of the fastest, and are produced when we are alert. When we begin to relax, slower alpha waves are produced. As we enter the stages of sleep, our brain waves continue to slow down, producing theta waves and then delta waves. But when our brain is aroused, it takes a longer time to produce slower brain waves, thereby inhibiting our ability to sleep. However, experienced meditators have been shown to have reduced levels of beta and alpha waves, possibly due to an increased level of calmness from the practice. These lower frequency waves may enable them to get past these barriers of an active brain and efficiently reach deep levels of sleep.
