Why Can’t I Sleep Even When I’m Completely Exhausted?

You’ve done everything “right.”

The blackout curtains.

The magnesium.

The cozy blankets.

No caffeine after lunch.

A bedtime routine worthy of a sleep podcast.

And then…

The lights go out.

Your body is exhausted.

But your brain decides it’s finally time to replay that conversation from three years ago, create tomorrow’s to-do list, solve every problem you’ve ever had, and imagine seventeen different worst-case scenarios.

If you’ve ever wondered,

“Why can’t I sleep even when I’m exhausted?”

you’re far from alone.

As an EMDR therapist in Colorado, it’s one of the most common questions I hear.

The answer is often surprising.

Sometimes insomnia isn’t only about sleep.

Sometimes it’s about protection.

Your Brain May Be Trying to Protect You

We often think insomnia means something is “wrong” with us.

But from a nervous system perspective, your brain may actually be doing exactly what it learned to do.

Your nervous system is designed to keep you alive.

If it has learned—through stress, trauma, chronic anxiety, unpredictable environments, caregiving, or difficult life experiences—that staying alert is safer than relaxing, sleep can become surprisingly difficult.

Even when you’re desperately tired.

Why Your Mind Gets Loud at Night

Many people describe bedtime like this:

• My to-do list suddenly appears.
• I replay conversations over and over.
• I worry about tomorrow.
• I can’t stop thinking.
• I feel “tired but wired.”

These aren’t signs that you’re failing.

They may be signs that your nervous system still believes it has work to do.

Internal Family Systems (IFS): What If a Part of You Is Trying to Help?

One of the things I love about Internal Family Systems is that it invites us to become curious rather than critical.

Instead of asking:

“How do I make these thoughts stop?”

Try asking:

• What is this part worried would happen if it let me sleep?
• What is it trying to help me with?
• How old does this part feel?
• What does it hope will happen by keeping me awake?

It sounds simple.

But it can completely change your relationship with insomnia.

Many protective parts believe things like:

• “If I think about it long enough, I’ll solve it.”
• “If I stay alert, I’ll be prepared.”
• “If I rehearse every possibility, I won’t get blindsided.”

When these parts finally feel heard, they often don’t have to work quite so hard.

Try This Tonight

Instead of arguing with your thoughts, try saying:

“Thank you for letting me know you’re worried about this. Your concerns make sense. Let’s meet tomorrow at 8:00 a.m. to think about it together.”

It may feel silly.

But many clients discover that their protective parts relax when they know they’ll be listened to later.

Your Body Has a Voice, Too

Insomnia doesn’t only happen in your thoughts.

It also lives in the body.

You might notice:

• Tight shoulders
• A racing heart
• A clenched jaw
• A fluttering stomach
• Restlessness
• Feeling like you simply can’t settle

From a somatic therapy perspective, these sensations are important information.

Many of us try to force relaxation before our nervous system feels heard.

Somatic therapy takes a different approach.

First We Listen. Then We Respond. Then We Invite.

Rather than jumping immediately into breathing exercises, we begin by noticing what the body is communicating.

Only after your nervous system feels acknowledged do we gently invite comfort.

That might include:

• A slower exhale
• Progressive muscle relaxation
• Feeling the support of your mattress
• A hand resting over your heart or tummy
• Orienting to cues of safety in your environment

If your body resists, that’s okay.

Resistance is information that your body may not feel safe enough to relax yet.

How EMDR Can Help Insomnia

Many people think EMDR is only for PTSD.

In reality, EMDR can also help address experiences that continue to keep the nervous system activated long after the danger has passed.

I’ve worked with clients whose insomnia was connected to experiences where their nervous system learned:

• Nighttime wasn’t safe.
• Rest wasn’t possible or valued.
• They had to stay vigilant or alert.
• Someone depended on them staying alert.
• Relaxing meant something bad could happen.

When those memories are reprocessed through EMDR, the nervous system often begins updating those old patterns.

Sleep can become easier but not because you’re forcing it, but because your brain no longer feels it has to stay on guard.

A Story I’ll Never Forget

Early in my career, I received a referral from a physician for someone who had struggled with insomnia for decades. They had already completed sleep studies, tried medications, and worked through standard behavioral approaches with little relief. I was their last ditch effort.

He was skeptical, I was a tiny bit nervous.

Together, we explored earlier life experiences, protective parts, and the nervous system patterns that seemed to be keeping sleep out of reach. During therapy we were also able to use EMDR to process a key memory connected to those patterns.

When they returned for their next appointment several weeks later, they shared that their insomnia was gone. We scheduled another follow-up to make sure those changes continued, and they did.

We were both surprised that this worked, even though theoretically and conceptually it made sense to me. He shook my hand and thanked me even while shaking his head that this even worked, and walked out of my office.

That experience reshaped how I think about insomnia.

While every person’s healing journey is different, and trauma-related insomnia is often more complex, it reminded me that addressing our parts, the core beliefs and memories and the nervous system, not just sleep habits, can sometimes make a meaningful difference.

Frequently Asked Questions

Why can’t I sleep even when I’m exhausted?

Sometimes insomnia is related to anxiety, trauma, or a nervous system that remains on high alert even when you’re physically tired.

Can EMDR help insomnia?

For some people, yes. EMDR may help when insomnia is connected to stressful or traumatic experiences that continue to keep the nervous system activated.

Can anxiety cause insomnia?

Absolutely. Anxiety often increases mental activity, muscle tension, and physiological arousal, making it difficult to fall asleep or stay asleep.

What therapy works best for insomnia?

The answer depends on the cause. CBT-I is considered a first-line treatment for many forms of insomnia. For people whose sleep difficulties are closely connected to trauma, chronic stress, or nervous system dysregulation, therapies such as EMDR, Internal Family Systems (IFS), and somatic therapy may also be helpful.

No. Insomnia can have many causes, including medical conditions, medications, sleep disorders, stress, anxiety, depression, lifestyle factors (new baby anyone?), and trauma. A comprehensive evaluation can help determine the most appropriate approach.
