Everything we do requires movement.
Movement allows us to walk, run, cook, procreate, and communicate. Movement is even required at the cellular level. Without movement, we would cease to exist.
Movement helps keep us healthy.
A variety of diseases are actually related to the lack of moving. Diabetes, obesity, hypertension, heart disease, and dyslipidemia (just to name a few) are all diseases caused in part by not moving enough. This is not news.
We know that exercise (which is really just a human invention to make up for our lack of movement), is good for our health.
Unfortunately, sedentariness (the lack of movement) has grown exponentially over the past few years. And so has the prevalence of these diseases.
While exercise is a great start to combat these diseases, it is not the only answer.
1 hour of exercise per day is not going to counteract the other 23 hours of the day you may not be moving. And it definitely cannot counteract a terrible diet.
We MUST start looking at our health multidimensionally.
Physically, mentally, and socially. Start moving more and eating better. Start meditating and managing your stress. Start surrounding yourself by people you enjoy and who build you up.
