❓ What is a Chronotype?
Your chronotype is your natural sleep-wake pattern determined by your biological rhythm. Some people are naturally morning types, others are evening types. It's not laziness—it's a genetically determined biological trait.
Understanding your chronotype helps you know when to sleep, work, and exercise most effectively. Rather than forcing yourself to be a morning person, living according to your natural rhythm is much better for your health and productivity.
🔬 Scientific Basis
This test is based on sleep researcher Dr. Michael Breus's chronotype theory. It classifies 4 sleep patterns based on research on circadian rhythm genes like PER3.
