Prolactin levels are typically highest in the early morning hours, between 2-5 AM. This natural spike in prolactin during the night helps support milk production for breastfeeding mothers.
Here's why prolactin levels peak at night:
- Circadian rhythm: Prolactin release follows a circadian rhythm, meaning it fluctuates throughout the day and night.
- Sleep-wake cycle: Prolactin levels tend to increase during sleep and decrease upon waking.
- Breastfeeding: Nighttime breastfeeding is often associated with higher prolactin levels, as the act of sucking stimulates prolactin release.
This natural fluctuation of prolactin levels is a normal part of the body's hormonal cycle.
