Why You Feel Exhausted Before Your Period (And What Your Body Needs Instead)
There was a time when I thought something was wrong with me because every month, like clockwork… I would hit a wall.
Not just “a little tired.” I’m talking about deep, can’t-think-straight, don’t-want-to-talk, overwhelmed exhaustion. And the frustrating part?
I was doing all the right things.
Eating clean.
Working out.
Taking supplements.
Drinking water.
So why did my body feel like it was shutting down?
If you’ve ever felt this way before your period, you need to know… Your body isn’t failing you.
It’s speaking to you.
And once you understand what’s actually happening, everything starts to make sense.
What’s Actually Happening in Your Body
The week before your period is called the luteal phase. This is when your body shifts gears. After ovulation, your body produces more progesterone, a hormone that’s meant to:
- calm your nervous system
- prepare your body for rest
- support potential pregnancy
At the same time:
- Estrogen begins to drop
- Your metabolism increases
- Your body becomes more sensitive to blood sugar changes
Translation?
Your body is literally designed to slow down. But most of us don’t.
Why You Feel So Exhausted
There are a few key reasons this phase can feel so intense:
1. Your Nervous System Is More Sensitive
Progesterone has a calming effect on the brain (through GABA pathways), but if your body is already stressed… it can feel like burnout instead of peace.
Chronic stress, poor sleep, and constant stimulation can make this phase feel overwhelming instead of restful.

2. Blood Sugar Is Harder to Regulate
In the luteal phase, your body becomes slightly more insulin resistant.
That means:
- you get hungrier
- you crave carbs more
- you crash faster if you’re not eating enough
If you’re skipping meals or under-eating? Then exhaustion gets worse.

3. Your Body Is Using More Energy
Your basal body temperature rises after ovulation, which means you are burning more calories just existing. Research shows energy needs can increase by ~100–300 calories/day in this phase.

4. You’re Pushing Instead of Partnering
This is the biggest one I see.
Women try to:
- push intense workouts
- stay up late
- keep the same pace as the follicular phase
But your body is asking for something different. And when you ignore that, it gets louder.
What Most Women Do That Makes It Worse
I say this with love because I did this too.
- Drinking more caffeine to keep up
- Eating less (or “trying to be good”)
- Overtraining
- Ignoring rest
- Adding more “detox” on top of an already stressed system
All of this pushes your body further out of balance.
What Your Body Actually Needs Instead
This is where everything shifts.
Not by doing more but by doing what’s right for this phase.
1. Eat More (Yes, Really)
Focus on:
- Protein (to stabilize blood sugar)
- Healthy carbs (fruit, root veggies, whole grains)
- Mineral-rich foods
This is not the time to under-eat.
2. Slow Your Movement Down
Instead of high intensity:
- walking
- strength training
- Pilates
- gentle movement
Your body will actually respond better to this.
3. Prioritize Rest Like It Matters (Because It Does)
- earlier nights
- less stimulation
- quiet moments
Even Jesus stepped away to rest.
Your body was designed with rhythm not constant output.
4. Support Your Nervous System Daily
Simple, free things:
- morning sunlight
- deep breathing
- stepping outside barefoot
- slowing your pace
These are not “extras.” They are foundational.
5. Stop Fighting Your Body’s Rhythm
This is the truth most women have never been taught: Your energy is not meant to be the same every day of the month.
God created:
- day and night
- seasons
- cycles
And your body reflects that design.
