26 Jul Surprising fact about your hormones
So, you probably know by now that estrogen has its own monthly rhythm, going up, then down, then up, then down again over the course of about 28 days (give or take depending on your personal cycle). But, did you know that estrogen also has a 24-hour daily rhythm, too? It’s true!
According to a study in the European Journal of Endocrinology, your body’s level of “free estradiol”–the key type of estrogen that impacts your mood, energy, brain skills and behavior–peaks around 7 am (it shifts to a little later in the morning during your period week), then it goes down in a wave-like pattern as the day goes on. (A little like a male 24-hour testosterone cycle.) Below is a chart the researchers created to illustrate what this 24-hour estrogen cycle looks like:
While scientists don’t yet fully know how this daily up-and-down affects us, this discovery is certainly intriguing and opens the door for further research.
