Why can’t I switch off at night even when I’m exhausted?

Posted on 2026-04-28 22:18:52

You’ve been staring at the back of your eyelids for three hours. Your body feels like a lead weight, your limbs are heavy, and yet your brain is running a marathon in the dark. This is the exhaustion-but-wired paradox. You are physically spent, but mentally, you’re hitting "refresh" on a browser that won’t load.

If you find yourself lying there while the clock ticks from 2:00 AM to 4:00 AM, you aren't just "a bad sleeper." You are likely experiencing difficulty switching off anxiety. In medical circles, this is often linked to a state of hyperarousal.

Hyperarousal is a fancy term for when your nervous system gets stuck in "fight or flight" mode. Normally, this system is meant to help you dodge a bus or survive a crisis. When you have anxiety, your brain forgets to switch it off, leaving your body on high alert even when you’re safe in bed.

Reality check: Everyone has a bad night’s sleep. If this is a recurring feature of your week, it’s not a character flaw—it’s a biological glitch that needs addressing.

The Invisible Symptoms: How Anxiety Looks Different in Men

For decades, the standard medical model for anxiety was built on the assumption that you’d look "nervous" or be visibly worried. In my nine years of interviewing men in the UK, I’ve found that men rarely "look" anxious in the way textbooks describe. Instead, we internalize it. We don’t shake; we when CBT doesn't help burn out.

When men deal with anxiety, it often manifests as a specific set of behaviors rather than an emotion. You might not feel "scared," but you will feel the physical consequences.

What it actually feels like:

The "Work-Mode" Hangover: You have to be "on" all day, so your brain refuses to drop the act once you hit the pillow. Physical Tension: Clenching your jaw or noticing your shoulders are up by your ears, even when lying flat. The Irritability Spike: You’re snapping at your partner or colleagues because your brain is exhausted from holding the tension together. Decision Fatigue: Even choosing a TV show feels like a high-stakes negotiation.

Reality check: If you’re acting like a "tough guy" during the day, your brain is just saving all that suppressed emotion for the exact moment you try to go to sleep.

Racing thoughts at night: The loop you can’t exit

When you have racing thoughts at night, your brain isn't just thinking; it’s problem-solving. It’s reviewing the email you sent at 3:00 PM, checking the bank balance for the third time, or rehearsing a conversation you’ll have next Thursday.

This is often referred to as "cognitive rumination." Simply put, it’s a mental loop where you keep going over the same ground, hoping to find a solution to a problem that usually doesn't need to be solved at 3:00 AM.

The Thought The Reality "I need to fix X project right now." The office is closed. You can't fix it. "I’m falling behind my peers." Everyone is curated online; you’re comparing your blooper reel to their highlights. "I’m never going to get to sleep." You will. The pressure to sleep is actually keeping you awake.

Reality check: No major life problem has ever been solved in the dark while lying under a duvet. The brain is lying to you; it thinks it’s being productive, but it’s just being destructive.

The Stigma Trap: Why we wait too long

In the UK, we have a "keep calm and carry on" culture that acts as a toxic barrier to health. We tend to view mental health struggles as a failure of willpower. You tell yourself, "I just need a beer," or "I just need to hit the gym harder," instead of acknowledging that you are struggling with sleep disruption anxiety.

By the time most men speak to a GP, they’ve been suffering for months, sometimes years. We wait because we’re afraid of being labeled, or worse, being told that it’s "all in our heads." Newsflash: the head is a body part. If your brain is malfunctioning, that’s a medical issue, not a personality defect.

Reality check: Asking for help isn't about being weak. It’s about maintenance. You wouldn't drive a car with a smoking engine for six months; don't do it to your brain.

Evidence-Based Pathways: What actually works?

If you search online, you’ll be bombarded with "life hacks" like cold showers, herbal tea, or expensive supplements. While some of these are pleasant, they aren't clinical solutions for chronic anxiety. If the issue is persistent, you need to look at what the evidence says.

1. Cognitive Behavioral Therapy (CBT)

CBT is a structured form of talk therapy. It’s not just "venting" to a therapist; it’s about identifying the patterns (like the thought loops mentioned above) and learning how to interrupt them. It’s the gold standard for insomnia and anxiety because it gives you practical tools to use when you’re lying awake at 3:00 AM.

2. Counselling

Sometimes, racing thoughts are anchored in unresolved stress or trauma. Counselling provides a space to unpack the "why" behind your anxiety. It’s slower than CBT but can be profound if your sleep issues are tied to life transitions or deep-seated pressures.

3. SSRIs (Selective Serotonin Reuptake Inhibitors)

These are the standard medication pathway for anxiety. They help regulate the neurotransmitters that keep your brain in that "fight or flight" loop. They aren't "happy pills" that change who you are; they are simply tools that lower the volume on your nervous system so you can start doing the work of recovering.

Reality check: None of these are "magic bullets." They require time, patience, and engagement. You won't be "fixed" in a week, but you will stop the slide into worse health.

A Final Word on Control

The hardest part of overcoming sleep anxiety is accepting that you cannot force yourself to sleep. The more you "try" to sleep, the more you stimulate the very brain activity that’s keeping you awake. It’s a vicious cycle.

If you're reading this at 2:00 AM, put the phone down. Stop googling symptoms. If your sleep is consistently disrupted, book an appointment with your GP next week. Mention the words "anxiety," "racing thoughts," and "insomnia." They’ve heard it all before, and they have a roadmap to help you through it.
