Biological Clock
Biological Clock
Your body’s internal timing system for sleep, energy, and hunger.
Details
The biological clock is the body’s natural timekeeping system. It helps regulate when you feel sleepy, alert, hungry, or low on energy, so when it gets disrupted, both your mood and your body can feel off balance.
💡 Real-Life Example
After a long flight across time zones, someone may feel wide awake at 2 a.m. because their biological clock is still adjusting.
