The whole of human organization has its shape in a kind of rhythm.
It is not enough that our hearts should beat in a kind of rhythm, always kept up to a standard at which it can meet as well as wholesome strain without upset. There are many other rhythms which we must be attuned to: the larger rhythms of night and day, of sleep and waking hours, of hunger and its gratification, and finally the big four—work and play and rest and sleep, which our organism must be able to balance even under difficulty.The only way to attain balance in all this is actual doing, actual practice, a program of wholesome living as the basis of wholesome feeling and thinking and fancy and interests.
Conditions of apparent imbalance, such as workaholism, burnout, insomnia, obesity and circadian desynchronosis, are ubiquitous and have been linked to adverse health consequences.
