Description

The secret language of your vital signs-and how to read and understand it.

From the firing of neurons in a fraction of a second to the monthly cycle of ovulation to a seasonal shift in sleep patterns, the human body runs on rhythms-all more knowable now than ever, thanks to wearables. Making sense-and making use-of these signals is something else, and this is precisely what Daniel Forger explains in Biological Rhythms.

Sorting through a plethora of data gathered over the past decade, this practical, user-friendly book gives readers the tools for reading and interpreting the rhythms that regulate physiological processes as varied and critical as sleep, brain activity, heart rate, hormone secretion, metabolism, and temperature. Once translated, the language of biological rhythms can be used to improve health and productivity-by athletes, travelers, and shift workers, sufferers of fatigue or sleep disorders, or those wishing to lose weight, monitor infection, or time fertility-in short, anyone with an interest in reading and understanding the body’s vital signs.
