Sleep plays a vital role in your mental health, physical resilience, and nervous system healing—but 1 in 3 adults aren’t getting enough of it. In this post (based on Episode 59 of the Regulate & Rewire podcast), Amanda breaks down what actually happens when we sleep, why it matters for your healing journey, and how to build sleep habits that stick. Rather than overwhelm you with complex science, Amanda breaks down what you need to know to care enough to make change—and shares simple strategies to help you do it. Whether you’re navigating insomnia, anxious spirals, or just exhausted from modern life, this is where we start.

Resources Mentioned:

What We Cover in This Episode

  • The difference between rest and regulation—and why sleep is both
  • Why most people underestimate their own sleep deprivation
  • The ripple effects of poor sleep on anxiety, mood, memory, immunity, and more
  • Tangible habits and environmental shifts that improve sleep hygiene
  • Why revenge bedtime, technology, and modern life make sleep so hard
  • What to do when you can’t sleep (even though you want to)

Why Sleep Needs To Be Taken More Seriously

We know sleep is important. But most of us don’t understand why. That’s where Amanda starts—by breaking down the science just enough to help you understand what’s happening in your body while you rest.

Sleep is essential for everything from memory consolidation and mood regulation to trauma processing and immune defense. In fact, more than 17,000 scientific studies link sleep deprivation to increased risk of anxiety, depression, cancer, heart disease, and more.

Yet one in three adults aren’t getting enough sleep. Nearly 40% of people report unintentionally falling asleep during the day. And for many of us, sleep is the first thing we sacrifice—even when we know better.

The Cost of Chronic Sleep Deprivation

Sleep deprivation doesn’t just make you tired. It rewires your baseline.

Amanda shares an eye-opening excerpt from Matthew Walker’s Why We Sleep to illustrate how chronic sleep loss affects your body and brain. Spoiler: it’s not just inconvenient. It’s dangerous.

When we don’t sleep:

  • Our brains can’t process emotion or consolidate learning
  • Our immune systems weaken
  • Our hormones shift, affecting appetite and stress response
  • Our vagal tone drops, making it harder to regulate stress and anxiety

And the kicker? When you’re sleep deprived, you don’t actually know how sleep deprived you are. Most people acclimate to suboptimal performance and reduced vitality—and think it’s normal.

How Sleep Supports Nervous System Healing

Sleep and nervous system regulation are deeply intertwined. Low vagal tone (a marker of poor parasympathetic function) is linked to anxiety, depression, and chronic illness. But improving vagal tone? That’s something sleep directly supports.

It’s while we sleep that our brain clears cellular debris, our gut resets, our muscles repair, and our nervous system settles.

Put simply: sleep is a free, powerful tool for healing and a biological non-negotiable.

Why It’s Hard to Sleep (Even When You Want To)

If you know sleep matters but still struggle to get enough, you’re not alone. Amanda acknowledges the complexity of modern life—especially for parents, high-achievers, and those with anxiety or trauma histories.

For many, sleep struggles stem from:

  • Environmental issues like light, temperature, or noise
  • Anxiety and a dysregulated stress response
  • Revenge bedtime procrastination (delaying sleep to reclaim personal time)
  • Poor sleep hygiene habits
  • Environmental issues like light, temperature, or noise

What Helps: Tangible Tips for Better Sleep

Amanda doesn’t just talk about why sleep matters—she workshopped solutions. Here are some strategies to start with:

Set Your Sleep Destination

Use the habit ladder framework to assess your current sleep pattern and build toward the goal of 7–9 hours of consistent, quality sleep each night.

Create Optimal Sleep Conditions

  • Cool room (65°F is ideal)
  • Blackout curtains or eye masks to block light
  • Quiet environment or white noise machines
  • Reserve the bed for sleep and sex only

Build a Pre-Bed Routine

  • Dim overhead lights 1–2 hours before bed
  • Avoid screens at least 30 minutes before sleep
  • Replace evening tech time with relaxing activities
  • Avoid heavy meals, caffeine, and alcohol close to bedtime

Use Movement & Light Strategically

  • Aim for 30 minutes of movement during the day
  • Get natural sunlight within the first hour of waking to support circadian rhythm

Respect Your Sleep Drive

  • If you can’t fall asleep, get out of bed and do a relaxing activity until you feel drowsy again

All of these are outlined in Amanda’s free Sleep – Essential 8 workbook, with habit ladders and resources to help you implement them step by step.

Three Tangible Takeaways

  1. Sleep is foundational for healing. It supports vagal tone, mental health, physical recovery, and emotional regulation.
  2. You might not realize how sleep-deprived you are. Chronic exhaustion resets your baseline and masks the harm being done.
  3. You can start small. Use tools like the habit ladder, dimming lights, or moving your phone out of the bedroom to get 1% better sleep tonight.
