A catchy phrase, but what does it mean?
What is self-care anyway? Does it mean eating more plants, exercising, meditating, all of the above? Does it do any good? How much is enough? What is the right kind of exercise, diet, stress-reduction technique?
In 1999 a study was published in The American Journal of Epidemiology that stated that people who were physically active had a two-fold likelihood of dying without a disability compared to those who were not active.
In Stan Malstrom, N.D.'s Own Your Own Body, he states it is better to exercise and eat poorly than to eat well and not exercise. Of course, it would be ideal to do both.
What is the best exercise? The one that you enjoy enough to do daily, as long as it does not cause injury. That could be Qi Gong, Tai Chi, yoga, walking in the woods, bicycling, swimming etc.
What is the best diet? That is such a controversial topic, made foggy by people with something to sell or a special interest to protect.
The most comprehensive research ever done on diet and disease was The China Study headed up by T. Colin Campbell, PhD. who was the NIH's leading researcher on the topic for over 40 years.
You might find the diet advocated by this former dairy farmer from Wisconsin a bit too exciting. However, take in the info and make changes at your own pace.
The third part of self-care is often ignored or even shunned – rest. I don't do this one very well at times. Busy-ness seems to be valued in our culture very highly. I even get comments like "wow, it's great that you are keeping so busy".
Diet, exercise and rest are called the "Three Free Therapies" in Traditional Chinese Medicine and are equally important. We are an over stimulated society. Take time every day to "un-plug". Turn your smart phone off. Enjoy some quiet each day (do Tai Chi without music, with your phone off, at a park – maybe).
When you sleep; be electronic free for an hour before bed and turn your phone off while sleeping.
The key to self-care is to make a start: exercise more, eat better, and rest more or smarter.
