My energy isn’t just lower in perimenopause—it has become impossible to plan around
With World Menopause Day coming up on October 18, I’ve been thinking about the symptom that has changed my daily life the most.
It isn’t the hot flashes.
It’s not knowing how much energy I’m going to have—or how long it will take me to recover from using it.
A good day for me can look completely ordinary from the outside. I work, get groceries, catch up on laundry and make dinner. I might even agree to weekend plans because I finally feel like myself again.
Then I wake up the next morning after what should have been enough sleep, and my body feels impossibly heavy. Taking a shower becomes something I have to prepare for. The laundry I felt proud of finishing yesterday is replaced by a new pile I don’t have the energy to fold.
Sometimes that exhaustion lasts an afternoon. Sometimes it takes the next two days with it.
The emotional part is almost harder than the physical fatigue. On a good day, I wonder whether I exaggerated how bad the previous week was. On a bad day, I wonder why I suddenly can’t handle a life I used to manage without thinking.
And making plans has become its own form of anxiety. Feeling okay when I say yes doesn’t mean I will be okay when the day arrives.
Reading this thread about unpredictable exhaustion made me realize how many of us are living some version of this. People described sleeping through the night and still needing a three-hour nap, getting only one clear day in a week, and using that rare good day to catch up before crashing again.
The pattern I keep seeing is not simply tiredness. It is a growing gap between what we can do and how long it takes us to recover from doing it.
I started reading about the physiology because I needed to understand why my body could feel so different from one day to the next.
What helped me understand it is that estrogen and progesterone do not gently and predictably decline during perimenopause. They can fluctuate sharply. And these hormones are not only involved in periods—they interact with parts of the brain involved in sleep, temperature regulation, mood, stress and pain.
That means several things can change at once. Sleep may be interrupted by night sweats or brief awakenings we barely remember. Anxiety can appear even when nothing obvious has changed in our lives. Headaches and pain can become harder to recover from. If periods become heavier or more frequent, iron loss can add another kind of exhaustion on top of everything else.
One small study of 85 perimenopausal women found that 62.4% were poor sleepers, with fatigue strongly associated with poorer sleep quality. That doesn’t explain every bad day, but it helped me understand why spending eight hours in bed doesn’t always mean my brain and body received eight hours of recovery.
I’m trying to stop tracking fatigue as if each day exists on its own. I’m paying more attention to where I am in my cycle, how often I woke during the night, whether my bleeding changed, what I did on the previous good day and whether the crash arrived 24 or 48 hours later.
I’m also trying not to use every good day to repay my entire life backlog. That is difficult when work, family and the house don’t pause for perimenopause. But feeling better for one day may not always mean that my recovery capacity has returned with it.
And I don’t want to assume that every symptom is hormonal. Heavy bleeding with fatigue is a reason to ask about iron and anemia. Sleeping enough but never feeling restored can justify looking more closely at sleep quality or sleep apnea. A major change in energy deserves to be taken seriously, even when perimenopause is a likely part of the picture.
For those still cycling: do you notice that the recovery gap becomes worse during a particular part of your cycle?
And for those who have reached menopause: did the unpredictability eventually settle, or did fatigue simply become a different, more consistent baseline?
What I’m slowly learning is that perimenopause hasn’t only changed how much energy I have. It has changed how much I can trust tomorrow’s energy—and that may be the harder adjustment.
