Light exposure is a powerful regulator of the circadian system. ☀️ Morning sunlight stimulates cortisol and serotonin, supporting daily energy and mood regulation, while 🌙 dimming evening light allows melatonin to rise, promoting restorative sleep.
Disruptions in these rhythms can influence sleep quality, mood stability, and hormone balance, with women often experiencing these shifts more acutely.
The Sleep Balance Test Kit from ZRT Laboratory provides an in-depth look at cortisol and melatonin levels across the day, helping to identify patterns that impact circadian alignment and hormonal health.
