The Science of Time in the Body — Circadian Rhythm, by Dr B B Chaudhary and Sarita Chaudhary

Could your daily routine be out of sync with your body clock?

Modern life rarely runs on the schedule our biology expects. Irregular sleep, artificial light at night, screen exposure, unpredictable meal timing, shift work, travel across time zones and inconsistent routines can all quietly pull the body's internal clock out of step.

This book explores how biological timing actually works, and how readers can use that understanding to build healthier, more consistent daily rhythms.

  • Artificial light at night
  • Screen exposure
