When it comes to mental and physcial wellbeing i really like Paul chek's 4 Doctor approach, he says there are 4 doctors within all of us they are:
DR QUIET (sleep 8 hour +)
DR DIET (healthy eating, natural wholesome foods 2-3 meals per day)
DR HAPPY ( livng your dream, what makes you happy, your legacy)
DR MOVEMENT ( exercise a balance of working out and a balance of working in)
Paul said the above 4 doctors where actually taken from ancient greek physicians they had the 3 doctors , dr diet, dr quiet and dr hapy but paul added dr movement as ur modern lifetstyes are so sedentary he said even washing clothes by hand back in those days was like a workout these days!
These doctors fall into 2 categories of yin and yang
YIN = dr quiet and dr diet , parasympathetic nervous system , we cultivate energy and draw energy into ourselves, feminie aspect
YANG = dr happy and dr movement, sympathetic nervous system, we expell and use up energy , the masculine aspect
our lives are a harmony and balance between these 2 opposing forces, we need to rest well gain vitality and then we have the seed and energy to do the things we enjoy in life. If were in balance then wellbeing is good but if we are out of balance then we are affected negatively.
I personally had break down a few years ago , completely utterly mental, emotional, physical and spiritual breakdown. Diagnosed with bipolar disorder and took a long time to rebalance again.
I try to live the above 4 doctors as best i can and it helps emensly. These seemingly 4 simple aspects of our lives are actually very difficult due to modern living, to sleep, rest ,eat and exercise adequately is difficult giving modern stresses, but these 4 staples really help to stabilize our physiology.
People often think of the "mind" as something seperate from the "body" but it is not so. often if we are emotionally and mentally out of balance you can guarantee that your endocrine system, nervous system, hormonal system is also out of balance.
That is why it is so important to eat well, sleep well and move some then we feel good. Movement does not have to be hardcore athletics or extreme fitness or cross fit, good movement can be just 20-30 minutes of walking a day which is very beneficial to out systems or perhaps some yoga or thai chi, which are energy building as opposed to a crushing gym workout which is very energy expending and depleting.
I often find myself looking to ancient practices and cultures for wisdom of good living. modern living makes people so complex that its easy to see how modern living can make us all crazy if we don't have healthy rituals and practices which keep the basics like sleep,diet and exercise our foundation for a healthy and happy life.
