Circadian Health
Why it matters
The circadian rhythm refers to your body’s natural clock, regulating sleep, energy, and mood. When in sync, it enhances sleep quality, duration, and consistency, reducing instances of sleep disturbances, insomnia, and fatigue.
When disrupted, it can lead to burnout and health issues including higher rates of depression, diabetes, heart disease, and cancer.
