The Inner Clock

Více o knize

The groundbreaking new science of re-syncing our circadian rhythms promises healthier, happier, and more sustainable lives. Within our bodies, a symphony of tiny timepieces is orchestrated by a master timekeeper in the brain. However, modern factors like artificial light, time zone changes, and late-night meals disrupt these internal clocks. Misaligned circadian rhythms can lead to poor sleep, decreased productivity, and increased risks of serious health issues. With recent advances in biology and technology, a circadian renaissance is emerging, highlighting the importance of aligning our rhythms for better health. The exploration of this science reveals how simple actions, such as morning walks and avoiding late meals, can help maintain our body clocks. It also raises intriguing questions about the timing of medical treatments and surgeries, as well as the potential for manipulating circadian rhythms to address global challenges like antibiotic resistance and food scarcity. Science journalist Lynne Peeples delves into these topics, engaging with scientists, astronauts, athletes, and patients involved in this movement. Her journey includes sleeping in a Cold War-era bunker, chasing the midnight Sun, and experimenting with light-adjusting headsets, all aimed at understanding how to reset our internal clocks for improved well-being.
