Circadian Rhythm

Real World Example

Imagine having a favorite TV show that airs at a specific time every day, and you plan your schedule around it so you don't miss an episode. Just like this show's consistent schedule helps you organize your day, your circadian rhythm is your body's internal clock that helps regulate when you feel sleepy or awake over a 24-hour period. Just as you know when to be ready by remembering the show's airtime, your body relies on the circadian rhythm to maintain a regular sleep-wake cycle, ensuring you're alert during the day and ready for rest at night.
