This is something we hear from clients all the time. They're sleeping lightly. Waking at 3 a.m. Heart racing. Feeling overwhelmed by things that never used to bother them. And they're told it's just stress.
Stress absolutely plays a role. But during perimenopause, there is also a very real physiological shift happening.
Progesterone is typically the first hormone to decline during this transition. When progesterone drops, the nervous system becomes more reactive to cortisol.
At the same time, estrogen fluctuations can affect serotonin and blood sugar stability. Add poor sleep and chronic stress, and the nervous system can feel like it's running on high alert.
If anxiety feels new or amplified during this season of life, it may be worth looking deeper rather than assuming it's "just stress."
