The Real Reason You're So Tired (And What to Do About It)

The Real Reason You're So Tired (And What to Do About It)

You’re not lazy. You’re depleted.

That 3 p.m. crash? The mental fog? The “is it bedtime yet” feeling at 10 a.m.? These aren’t quirks of getting older—they’re signals.

Let’s break down the most common, research-backed culprits behind chronic fatigue in women over 40 and the simple, joyful fixes you can start today.


1. Blood Sugar Swings = Energy Rollercoaster

Even a healthy-looking granola bar can send your blood sugar soaring… then crashing.

📚 The science: Blood sugar spikes cause a temporary high, followed by fatigue as insulin kicks in to bring it down (Johns Hopkins Medicine, 2022). Frequent crashes lead to irritability, hunger, and mental fog.

Try this:

  • Prioritize protein + fiber at every meal (think tofu + veggies, or lentils + leafy greens).

  • Avoid naked carbs (carbs without protein/fiber/fat).

  • Get moving after meals - walking helps regulate glucose response.


2. You're Tired Because You’re Wired

Scrolling late, worrying constantly, running on to-do lists instead of rest? That’s nervous system dysregulation.

📚 The science: Chronic stress raises cortisol and decreases melatonin, leading to poor sleep and disrupted circadian rhythms (National Institute of Mental Health, 2021).

Try this:

  • Morning sunlight (5–10 minutes) regulates your sleep-wake cycle.

  • Meditate daily - even 5 minutes counts.

  • Create a 20-minute bedtime wind-down ritual (no screens, low lights, maybe a little magnesium).


3. Perimenopause Might Be Creeping In

Even if your cycle is regular, hormones may be shifting. Estrogen affects sleep, energy, and even blood sugar.

📚 The science: Estrogen supports serotonin (mood) and insulin sensitivity. As levels decline, sleep issues, low mood, and sugar cravings rise (The North American Menopause Society, 2023).

Try this:

  • Strength train 2–3x/week to support metabolic health.

  • Focus on omega-3s (chia seeds, walnuts, flax) and plant-based iron (beans, greens).

  • Stay hydrated. It sounds basic but is wildly effective.


4. You’re Doing Too Much and Not Enough of What Matters

Midlife women often hit the "invisible workload" wall: careers, caregiving, house stuff, emotional labor. Burnout central.

📚 The science: Decision fatigue reduces willpower and increases cortisol, leading to lower energy and motivation (Baumeister et al., 2010).

Try this:

  • Automate where possible (meal plans, grocery delivery, workout schedule).

  • Build a “joy list” and do 1 thing from it daily.

  • Outsource decisions - join a coaching program (I know a good one 😉).


Bottom Line:

More coffee isn’t the answer. More clarity, better fuel, and tiny rituals that fill your cup? That’s the game-changer.

If you’re ready to feel good again—not just “functioning,” but actually vibrant—start with one small shift this week. That’s all it takes.
