Most people's nervous systems are incredibly overactive, especially the "go go go" part which is called the sympathetic nervous system. When the nervous system is overactive the organ systems, flow of energy and blood in our bodies become imblanced. This can lead to dis-ease and inflammation of the body, which also affects the mind and emotions .As a result we make decisions and act out based on these imbalances over and over again in our daily habits
(Yes...Lifestyle is a big factor unless something from the outside environment invades the body like a traumatic injury, cold, damp, heat or wind)
Over time the body gets depleted from overworking so hard, even though we don't feel it at the time.It's like having the gas pedal in your car pushed all the way down, but you are still parked but there are many other ways the body and mind can be affected.
There are many highways in the body, called meridians, that link up with the nervous system and organs.These highways are directly related to the 5 elements we have in our bodies (Fire, Earth, Metal, Water, Wood)
Acupuncture, one aspect of Chinese Medicine, works by inserting needles into specific areas on meridians (highways) for a specific effect to balance the energy, blood, organs and nervous system.There are 365 acupuncture points!
Kundalini yoga and meditation work in a similar way to acupuncture by balancing the meridians (and therefore the nervous system and organs) by using different postures, mudras and mantras. It gives a specific effect on the brain and nervous system to help you feel like "you" again.
In a way, you are giving yourself acupressure (acupuncture without the needles)!
Note: Chinese medicine/acupuncture is more complex. Kundalini yoga doesn't replace Chinese Medicine or vice versa but they complement one another really well.
You can move physically and mentally away from the mindset of "I've always been this way" towards a mindset of interacting with yourself and the world with more freedom and choice without denying any part of the self.
