Almost every form of life, plant, animal or human being has an internal clock for measuring time, giving rise to rhythms. Rhythms are controlled by a biological clock situated in the brain. This clock strongly relies on sunlight and darkness. In humans, too, there are internal clocks that regulate metabolism, physiology and behavior. When we are well, our body rhythms work in synchrony but illness, travel across multiple time zones, shift work schedules, etc. often throw the rhythms out of tune. This book makes us feel the presence of the body clock within us and realize its importance in bodily functions. Listening to our body clock tick and making amends in our day-to-day life holds implications for improving our lives.
