How to Feel Less Tired During the Day: A Nurse Practitioner’s Guide for Women Over 40

As a Family Nurse Practitioner who has spent years caring for women in their 40s, 50s, and beyond, one of the most common concerns I hear sounds something like this:

“I sleep fine, but I still feel exhausted all day.”
“By lunchtime, I feel like I’ve run a marathon.”
“I thought this level of tired was just part of getting older.”

Let me be very clear—it doesn’t have to be this way.

Yes, your body changes after 40. Your hormones fluctuate. Your sleep might be lighter. Stress hits differently. But chronic fatigue is not something you’re just meant to push through. Often, it’s your body trying to whisper something before it has to shout.

So, from one woman to another—and from a nurse practitioner who genuinely wants you to thrive—here’s what might be going on, and how you can start feeling more like yourself again.


1. Let’s Talk About Sleep Quality, Not Just Sleep Hours

You might think you’re getting enough sleep. You’re in bed for seven or eight hours, you don’t remember waking up, and you’ve ruled out insomnia. So why do you still feel groggy by mid-morning?

Sleep quality is just as important as sleep quantity. Especially over 40, our sleep patterns become more fragile. Hormonal shifts, particularly declining progesterone and estrogen, can make it harder to get into the deep, restorative stages of sleep that keep you energized.

Here’s what I recommend to my patients:

  • Assess your environment. Light, noise, temperature, pets, and even a restless partner can disrupt your sleep cycles without fully waking you up. Consider blackout curtains, earplugs, or a white noise machine.
  • Limit screens before bed. Blue light from phones, tablets, and TVs suppresses melatonin, the hormone that helps you fall—and stay—asleep.
  • Establish a pre-sleep ritual. A warm bath, a light stretch, a book, or breathing exercises can train your brain to start winding down.
  • Stay consistent. Your brain loves predictability. Going to bed and waking up at the same time—even on weekends—helps regulate your natural circadian rhythm.

2. Water First, Caffeine Second (Yes, Really)

Caffeine is a quick fix for tiredness, but it’s not a long-term solution. In fact, it often backfires. As a nurse practitioner, I see women who rely on caffeine all day, only to struggle with sleep at night—perpetuating the cycle of fatigue.

Here’s a simple shift that works wonders:

  • Start your day with a full glass of water. After 6–8 hours of sleep, your body is dehydrated. That “morning slump” might be dehydration masquerading as tiredness.
  • Before each cup of coffee, drink water. This helps you stay hydrated, prevents energy crashes, and often reduces your caffeine intake naturally.
  • Cut off caffeine by early afternoon. Even if you don’t feel it disrupting your sleep, caffeine lingers in your system and can block your brain’s natural sleep signals.

If you love your morning coffee, keep it! Just be mindful of how much, how often, and when.


3. Move Your Body, Even in Small Ways

One of the best natural energy boosters? Movement. But here’s what I tell my patients: this doesn’t mean you need to join a gym, sign up for boot camp, or dedicate an hour a day to exercise.

In fact, gentle, consistent movement is often more effective for women over 40 than intense workouts that can spike cortisol.

Try this:

  • Walk for 15–20 minutes after lunch or dinner
  • Do a 10-minute YouTube yoga or Pilates video
  • Dance around the kitchen while cooking
  • Stretch before bed or during work breaks

Movement increases circulation, releases feel-good hormones, and improves sleep—without depleting your energy reserves. It’s about finding what feels doable and enjoyable for your body.


4. Feed Your Energy with the Right Foods (Especially Protein)

As we age, our bodies metabolize food differently. Blood sugar fluctuations, insulin resistance, and slower digestion can leave you feeling foggy and drained—especially if your meals are heavy in carbs and light on protein.

From a clinical perspective, here’s what helps:

  • Start every meal with protein. Eggs, Greek yogurt, protein smoothies, tofu, beans, lean meat, or fish help stabilize blood sugar and sustain energy.
  • Don’t fear healthy fats. Avocados, nuts, seeds, olive oil, and fatty fish nourish your brain and reduce inflammation.
  • Minimize ultra-processed carbs. They give a quick high, followed by a crash. Think pastries, white bread, sugary drinks, and many snack foods.
  • Watch for under-eating. Some women unintentionally eat too little—especially when trying to lose weight—leading to nutrient deficiencies and chronic fatigue.

If energy is an issue, look at what fuels you’re putting in your tank.


5. Morning Light = More Daytime Energy

Your brain takes cues from the environment to know when it’s time to be alert—or when it’s time to wind down. Getting exposure to natural light early in the day helps regulate your circadian rhythm, supporting better energy during the day and better sleep at night.

Simple ideas:

  • Open the blinds first thing in the morning
  • Step outside within an hour of waking, even for just 5–10 minutes
  • Eat breakfast near a sunny window

Many of my patients who struggle with sleep-wake cycles see a huge improvement just by getting more daylight in the morning.


6. Protect Your Energy By Managing Stress

Here’s something I say often in my practice: Stress is not just mental—it’s physical too.

When you’re constantly in “go” mode, your nervous system gets stuck in a state of hyper-vigilance. Cortisol—the primary stress hormone—stays elevated, and over time, it wears you down. You feel tired, wired, overwhelmed, and emotionally drained.

Try stress-soothing habits like:

  • Deep belly breathing for 3–5 minutes
  • Journaling what’s on your mind
  • Saying “no” to non-essential obligations
  • Spending time in nature
  • Taking a tech break (even just 30 minutes can help)
  • Listening to music that calms or uplifts you

Energy isn’t just restored through sleep. It’s also restored when we feel safe and grounded.


7. Listen to Your Hormones

Hormones play a bigger role in your energy than most women realize. In your 40s, levels of estrogen, progesterone, and even thyroid hormones can fluctuate. These changes affect your mood, metabolism, sleep, and yes—your energy.

If you’re doing all the right things and still feel exhausted, don’t guess—get tested.

Ask your provider to check:

  • Thyroid panel (TSH, Free T3, Free T4)
  • Ferritin (iron stores)
  • Vitamin B12 and Vitamin D
  • Estrogen and progesterone (especially if you’re perimenopausal)

We often uncover hidden deficiencies or hormonal imbalances that are simple to treat once identified.


8. Take Intentional Breaks During the Day

As women, especially over 40, we’re often expected to do it all—at work, at home, for everyone else. But constantly pushing without breaks leads to burnout.

Your body is not a machine. It’s a living, breathing system that needs rest.

Build in energy-replenishing moments like:

  • A 5-minute reset after lunch (step outside, stretch, close your eyes)
  • A quick power nap (10–20 minutes max)
  • Mini movement breaks between tasks
  • Just sitting still—without a screen or to-do list

Micro-breaks help your nervous system reset and prevent the build-up of stress that depletes your energy by 3 p.m.


9. Be Gentle With Yourself (Compassion Is Healing)

If you’re tired, your body is not betraying you—it’s speaking to you.

Maybe it’s asking for more rest. Maybe it’s asking for more support. Maybe it’s simply saying, “Please stop trying to be everything to everyone.”

As a Family Nurse Practitioner, I want you to hear this:

You’re not lazy. You’re not broken. You’re just human—and maybe a little overextended.

You don’t have to earn rest. You don’t have to justify slowing down. You are allowed to take care of yourself, just as you care for everyone else.


10. Final Thoughts: You Deserve to Feel Energized, Not Exhausted

Fatigue is not a badge of honor. It’s not a requirement of womanhood or midlife. And it’s not something you’re stuck with forever.

Start small. Try drinking water first in the morning. Step outside and feel the sun on your face. Add a little protein to your breakfast. Take a mindful break in the middle of your day. Schedule those labs you’ve been putting off.

Little by little, those choices create a life that feels more vibrant and sustainable.

As your Nurse Practitioner—and someone who truly believes in the power of women over 40—I want you to know that it’s absolutely possible to feel good in your body again.

Not because you’re “pushing through,” but because you’re finally giving your body what it really needs.
