Your hormones aren’t random.
They follow circadian rhythms, 24-hour patterns influenced by light exposure, sleep, meal timing, and stress.
Cortisol should rise in the morning and fall at night.
Insulin responds to when and how you eat.
Reproductive hormones are sensitive to both sleep and stress patterns.
When these rhythms are disrupted
through late nights, irregular meals, chronic stress, or poor sleep,
hormonal signaling becomes less efficient.
This can show up as:
• fatigue
• cravings
• poor sleep
• weight changes
• cycle irregularities
The goal isn’t perfection.
It’s consistency.
Start with:
• morning light exposure
• regular meal timing
• consistent sleep/wake times
• reducing late-night stimulation
