Your brain is an incredible electrochemical organ. There is always some amount of electric activity going on there, whether you are asleep or awake, engaged in activities or focused in meditation. Scientists have been attempting to discover the precise effects of meditation on the mind and body. When you teach your brain to stay awake and calm during meditation, you not only improve your emotional intelligence but also your mental power. Physical well-being is naturally enhanced by a strong, robust mind.
Mediation and the Brain
Mindfulness is good for the brain in a lot of ways, and almost everyone agrees with that. An article in Forbes magazine talks about ways “meditation can actually change the brain.” They say that the benefits range from better brain preservation as we get older to better results for students at school.
During an eight-week study at the University of Massachusetts Medical School’s Center for Mindfulness, it looked like participants’ brains had started to change after just two months of daily mindfulness, which was about a half hour a day.
The benefits of meditation on brain waves has received a lot of attention lately. When signals are sent between neurons, an electrical impulse is produced. Brain waves are referred to as “neural oscillations” by scientists. One widely recognised categorization system ranks oscillations from greatest to lowest: gamma, beta, alpha, theta, and delta. Each corresponds to a certain type of action.
Gamma waves
Gamma brain-waves dominate when our minds are actively learning or overactive. They hasten the learning process; knowledge is best stored when in the gamma state. Experiments tracking the brainwave activity of experienced Tibetan meditators found that uncontrolled gamma waves can produce anxiety. During their practise, their gamma waves were found to be two to three times higher than the resting level, indicating an unusual level of attentiveness while being in a profound, relaxed state of meditation.
Monitoring also revealed constant gamma synchronisation, which suggests that waves from various portions of their brains were interacting in an unexpected way. Beta waves are the next in line. They usually take over while our thoughts are focused on simple chores like planning and arranging as we go about our everyday lives.
Alpha waves
When we participate in activities that calm the mind and body, such as taking nature walks, attending yoga courses, and, of course, meditating, Alpha waves tend to prevail. Alpha waves are also suggested to safeguard the brain from overthinking and overreacting to unnecessary thoughts and stimuli. Isn’t this similar to mindfulness practise? Neuroscientists recently discovered a link between increasing alpha brain waves (through electrical stimulation or mindfulness and meditation) and the capacity to alleviate depressed symptoms and boost creative thinking.
Theta waves, which are even slower, are prominent during profound relaxation, dreaming, and Buddhist meditation.
Theta waves
Finally, theta brain waves are commonly linked to profound, dreamless sleep.
There’s no need to memorise all of these different types of brain waves, but it might be inspiring to know that contemporary scientific data verifies what meditators have known for thousands of years: meditation is excellent for both the body and the spirit. Simply sit, be conscious, and let your body and mind to naturally relax and become awake. The brain waves will look after themselves!
Enhanced well-being
Meditation benefits the brain by strengthens some brain regions, such as those responsible for memory, compassion, and empathy. Meanwhile, brain regions linked with fear, tension, and anxiety (such as the amygdala, the “fight or flight” centre) begin to shrink.
Stress neurotransmitters may diminish, while dopamine, a pleasure neurotransmitter, may rise. These and other minor changes contribute to an overall sense of improved health and well-being.
Meditation enables us to progressively transform the ingrained tendencies in ourselves that we despise. Furthermore, studies have shown that meditation promotes resilience. It also appears to alter the way individuals absorb pain by actively lowering the stress of negative reactions to discomfort, even when the meditators are not meditating!
