Meet the Hormone That’s Hijacking Your Sleep: How Cortisol Affects Insomnia and What to Do About It

Meet the Hormone That’s Hijacking Your Sleep

Are you lying in bed, exhausted — but wide awake?

Waking at 2am with a racing mind?

Or getting through the day feeling wired but never rested?

It could be your cortisol levels — and they may be working against your sleep.

What Is Cortisol and Why Does It Matter for Sleep?

Cortisol is your body’s main stress hormone. It plays a crucial role in:

Regulating your energy levels

Responding to stress

Controlling your sleep-wake cycle (circadian rhythm)

In a healthy rhythm, cortisol peaks in the morning (to help you feel alert) and dips at night (to allow your body to rest).

But when you’re under chronic stress, burnt out, anxious, or struggling with poor sleep over time, your system can get out of sync.

And that’s when things go wrong.

Cortisol and Insomnia: The Cycle No One Talks About

When cortisol spikes at the wrong time — like late at night or early morning — it can create a vicious sleep-stress loop.

You might experience:

Racing thoughts at bedtime

Difficulty falling asleep despite feeling tired

Waking up in the early hours (especially between 2–4am)

Feeling alert or agitated at night but exhausted by morning

This isn’t just “bad sleep.”

It’s your body stuck in a state of hyperarousal — a constant stress-alert mode that overrides natural sleep signals.

Why CBT-I Works for Cortisol-Driven Sleep Issues

The good news?

You don’t need to live with this forever — and you don’t need to rely on sleep aids long-term either.

CBT-I (Cognitive Behavioural Therapy for Insomnia) is the most effective, evidence-based approach for chronic insomnia.

It helps you:

Rebuild a healthy sleep pattern

Reduce nighttime cortisol spikes by calming the nervous system

Shift unhelpful thoughts and behaviours around sleep

Break the “wired but tired” cycle

At Your Sleep Clinic, I work with clients experiencing cortisol-related insomnia due to:

Menopause and hormonal changes

Shift work and irregular schedules

Long-term stress or burnout

Parenting and mental overload
