I have just started to read an interesting book "Curing Stress, Anxiety, and Depression Without Drugs and Without Talk Therapy" by Dr. David Servan-Schreiber M.D. Ph.D.
here we are mainly focusing on supplements to improve our health but this is only a part of the puzzle and we should maybe consider also our life style and how to manage stress.
This book is very interresting and introduces 4 technics. I have already read the first one: heart coherence. A big thing we might forgot to consider.
Here is a definition i found on the net:
"Your heart has its own nervous system with a built-in pacemaker. Even if we could disconnect your heart and brain, your heart would keep on pumping.
But that's just the beginning.
Because your heart is not just a "pump", speeding blood through your body.
Your heart is a highly complex, self-organized information-processing centre that is communicating with and influencing the brain (in your head) by way of other parts of the nervous and hormonal system.
In fact, the heart's brain is so complex that it often acts independently of (or in parallel with) the head's brain and has sprouted a whole new area of study called "neurocardiology".
And the heart is not just a brain -- it's also an endocrine gland, producing a number of hormones, many of which are the same hormones produced in and used by the head's brain.
So we start to see that your heart is a central link between itself, your head's brain, and your body's hormonal system. The central hub of our body and mind wheel, as it were.
Your nervous system is more than your brain and spinal cord. These two are known as your central nervous system, but you also have a peripheral nervous system that links your brain and all the other parts and systems of your body.
The peripheral nervous system also includes two parts: the somatic or voluntary nervous system (which controls your skeletal muscles) and the autonomic nervous system, which carries information from and to the internal organs, glands, and the immune system.
Then, there are two parts of the autonomic system we'll be focusing on and these are the sympathetic and the parasympathetic systems.
You can think about your sympathetic nervous system (SNS) as your "stress" system. When you are stressed, your SNS kicks into gear to prepare your body for "fight or flight": your blood pressure goes up, your heart speeds up, you breath harder, your digestion stops, you secrete adrenaline -- you generally get ready to fight back or get the heck out of there.
Your parasympathetic system (PNS), on the other hand, does virtually the opposite. It kicks in when the excitement is over and you can afford to settle down to a more peaceful, "steady state": you digest your food, your heart slows down, your blood pressure stays low, your bowel and bladder resume normal functioning.
While you want your SNS to be able to kick in in an emergency, it's not the place you want to be over the long term (or just even for too long...). Chronic stress is associated with the development of many physical, emotional, and even cognitive problems. For example, chronic stress actually can kill cells in the hippocampus - a structure in your brain that is linked with memory storage.
What's this got to do with your heart?
Well, your heart is responsible for maintaining the balance between the sympathetic (think stress) and parapsympathetic (think peace) nervous systems. And since the balance between these two systems affects the functioning of the brain as well as keeping the rest of the body in balance....well, you can start to see why it's a good place to begin."
