As a 49 year old nutritionist with 20+ years of experience specializing in women’s hormones and metabolism, I want to change how you think about sleep.

Because most women in perimenopause think sleep is about rest. It is actually where your metabolic health is won or lost every single night!

Here is what is happening while you sleep:

🧬 1. Your growth hormone is repairing your muscle
The majority of human growth hormone is released during deep sleep. Growth hormone drives fat burning, muscle repair and metabolic rate. When cortisol is elevated at night, as it is in perimenopause, deep sleep is suppressed and growth hormone cannot do its job. 
You wake up with less muscle and a slower metabolism than the day before.

🩸 2. Your blood sugar is either stabilizing or spiking
Research published in PMC confirms that sleep disruption causes a measurable increase in morning glucose levels due to elevated cortisol and growth hormone resistance. If you wake up hungry, craving carbs or feeling puffy you are seeing the result of a blood sugar event that happened while you were sleeping.

😴 3. Your hunger hormones are being set for the entire next day
Restless sleep from elevated cortisol levels disrupts the production of ghrelin and leptin, the hormones that regulate hunger. Ghrelin which signals hunger increases while leptin which signals fullness decreases.  Every poor night of sleep programs your body to overeat the following day regardless of your intentions.

Sleep is not passive after 40. It is the most important metabolic lever you have. And most women are not protecting it.
