Why Am I Always So Tired? 5 Hidden Causes of Low Energy in Women 35+

Low Energy in Women Is Often Misunderstood and no, It's Not “Just about Aging”

“I used to think constant fatigue was just part of life as I got older, but turns out, my body was trying to tell me something.” -- Nelea Lane

If you're experiencing low energy, especially as a woman over 35, it's easy to assume you're just doing too much or not sleeping enough. But for many women, low energy is actually a symptom of deeper imbalances from hormone shifts to gut health disruptions, nutrient gaps, or emotional burnout.

You deserve to know what’s really going on, and how to start feeling like yourself again — without guessing.

5 Hidden Causes of Low Energy in Women 35+

1. Hormone Imbalances (Including Perimenopause + Post-Hysterectomy)

Hormones naturally fluctuate as we get older — but things like estrogen dips, thyroid changes, and post-hysterectomy shifts can leave your energy levels in a constant state of flux. If you’ve been noticing brain fog, energy crashes, or mood dips alongside your cycle (or even without one), hormones may be part of the story.

"I felt like I was dragging myself through the day. Turns out? It wasn’t burnout. It was my hormones." -- Nelea Lane

2. Nutrient Deficiencies (Even if You Eat Pretty Well)

For women especially, low iron, magnesium, B12, and vitamin D are common culprits in fatigue. Stress and poor gut absorption can make it harder to absorb nutrients even when you’re eating healthy. A quick blood panel and the right support can make a huge difference.

3. Gut Health Issues

Your gut does more than digest food. It also impacts your mood, motivation, and mental clarity. If your gut-brain axis is out of balance, your energy can take a major hit. Think: afternoon crashes, poor sleep, low serotonin, and inflammation. Learn more about how this works in the Finding Happy Guide.

4. Chronic Stress and Nervous System Overload

We’ve normalized “always being on.” But your nervous system was never designed to live in constant go-go-go mode. Over time, this can disrupt your cortisol rhythm and leave you feeling flatlined. Stress management isn’t fluffy — it’s essential.

5. Lack of Restorative Sleep

You might be sleeping… but are you actually resting? Hormones, stress, and screen time all play a role in how well your body repairs overnight. If you wake up tired no matter what, it’s time to look deeper at sleep quality, not just quantity.
