Moms: Here’s Why You’re Still Tired After 8 Hours of Sleep

I see you Mama. You went to bed at a reasonable hour. You got your 8 hours (or close to it).. and yet you wake up tired, foggy and already behind.


What gives?


In honour of Mother’s Day. Let’s look at some of the reasons why… Because wouldn’t finally feeling rested be the ultimate gift?



1. You’re Still “On Call”


Even in sleep, your nervous system may not fully switch off. You’re listening for the kids (even subconsciously) and waking at every small noise. 


This leads to light, fragmented sleep cycles where your body stays in a semi-alert state with limited deep restorative sleep.


The Solution: Try to take a few minutes to “wind down” before bed. Practice some deep breathing, gentle stretching, and gentle self massage in low light to show your body that you are safe and preparing for rest. 



2. The Mental to Do List Never Ends


Motherhood comes with dozens of invisible “open tabs” in your mind. You lie awake mentally sorting through everything that needs to be done, and your sleep quality suffers. Even if you don’t feel stressed, your body does.


The Solution: Keep a notebook on your bedside table and do a 5 minute “brain dump” before bed. Write it all down, get it all out of your head to deal with after you get your zzz’s.



3. Blood Sugar Swings 


It’s not uncommon for moms to skip meals, eat on the go, run on coffee alone, or reach for those quick carb heavy snacks when a quiet moment presents itself.


All of this can lead to nighttime blood sugar crashes, which trigger cortisol (stress hormone) spikes, which pull you out of deep sleep.


The Solution: Prioritize your protein at every meal and snack. This will help to keep your blood sugar more stable. Consider a balanced snack an hour or so before bed like greek yogurt and berries, or apple slices and peanut butter to help keep things steady through the night.



4. Your Circadean Rhythm Is Off


Chronic stress, even the “normal” kind,  can dysregulate your body's natural wake/sleep pattern. This could look like feeling wired at night, but exhausted in the morning, or waking up wide awake at 2-4 AM and crashing out at 3 PM.


The Solution: Reset your rhythm- Follow a consistent bedtime and wake up schedule, even on weekends. Get natural light in your eyes first thing in the morning, and limit blue light (screens) for at least an hour before bedtime. 



5. You’re Nutrient Depleted


Sleep might not even be the issue, it might be your body getting the right fuel to keep going! Motherhood is physically demanding, and we often see nutrients like magnesium, iron, B vitamins, and omega 3’s getting depleted at higher rates. 


Even mild deficiencies can leave you waking up tired, no matter how long you slept. 


The Solution: A high quality multivitamin is your friend. Talk to your healthcare provider about what is right for you. 



A Tired Mom’s Supplement Survival Kit


Let’s be clear: supplements aren’t a substitute for sleep, nourishment, or support.

But when your body is depleted (which many moms are), the right support can make a noticeable difference in how you feel day to day, and how well you recover overnight.

Here are some of my go-to for moms:


  • Magnesium - Supports deeper, more restorative sleep, helps calm a wired-but-tired nervous system, can reduce muscle tension, headaches, and irritability.


  • B Vitamins (Especially B6 + B12)- Support energy production at a cellular level, help regulate stress response and mood, important for hormone balance.


  • Omega-3s- Support brain function, mood, and inflammation balance, helpful for postpartum recovery, can support more stable energy and emotional resilience.


  • Adaptogens (like Ashwagandha)- Help regulate cortisol, can improve sleep quality over time


  • Iron (If You Need It)- Low iron = fatigue, poor sleep, brain fog, especially important if you have heavy periods or postpartum depletion. ***Important: Always test before supplementing iron.


  • Vitamin D- Supports mood, immune function, and energy


  • Herbal Nervous System Support- Simple, gentle options like: Chamomile, Lemon balm, Lavender. These can be a beautiful addition in the evening to help signal safety and rest to your body.



Happy Mother’s Day!
