Tired But Wired: Why Your Body Won't Settle (And How to Help It)

My clients regularly talk about being exhausted, in a way they can't describe. Drained to the max, as if they have no fuel - but unable to rest, sleep or let go. It's an experience we refer to as 'tired but wired' and is very common to people who have experienced prolonged trauma. I see it often, and I also see people learn to overcome it - here is an introduction on what it is and how to tackle it.

You are bone tired. You have been tired for a long time. But when you finally get a moment to stop, your body won't let you. Your mind keeps moving, your chest stays tight, and sleep either won't come or doesn't feel restoring when it does. You might find yourself snapping at small things, or going completely numb. You might feel hungry and have no appetite at the same time.

This is not you failing to relax. This is a very specific physical state, and it has a name. Once you understand what's happening inside your body, it becomes much easier to know what to do about it.

...the alert setting has been on, at varying levels of intensity, for months or even years.

Your Body's Alert System

Your nervous system has two main modes. Think of them as two different settings on the same dial.

The first is the alert setting. This is sometimes called the fight-or-flight response. When your brain detects danger, it sends a signal that floods your body with stress hormones, mainly adrenaline and cortisol. Your heart rate goes up. Your breathing becomes faster and shallower. Blood moves away from your digestive system and into your muscles. Your senses sharpen. Your body is preparing to act.

The second is the rest-and-recover setting. This is the state in which your body repairs itself, digests food properly, consolidates memories, regulates mood, and, crucially, sleeps. You cannot properly access this setting while your alert system is running.

Here is the problem for people who have spent a long period of time in a stressful or threatening relationship: the alert setting has been on, at varying levels of intensity, for months or even years. Your body has been doing an extraordinary job of keeping you functioning under pressure. But that comes at a cost.

The Cortisol and Adrenaline Hangover

When the alert system fires, adrenaline moves through your body very quickly. But cortisol, the other main stress hormone, works more slowly and stays in your system much longer. It is designed to keep you mobilised after an immediate threat has passed, in case the danger returns.

This made sense in the environment human beings evolved in. It makes life considerably harder when the source of stress is ongoing, recurring, or unpredictable.

For people navigating co-parenting contact, legal processes, difficult communications, or simply the slow work of rebuilding a life after relationship trauma, the cortisol response rarely gets a chance to fully clear. A stressful message arrives. Cortisol goes up. It begins to come down. Another message arrives. It goes up again. Over time, the baseline level of cortisol in the body stays elevated even when nothing stressful is actively happening.

The result is what many people describe as feeling tired but wired. Your body is depleted from being on alert for so long, but the hormone levels keeping you in that state haven't dropped enough to allow genuine rest. You are exhausted and activated at the same time. Neither fully functioning nor fully recovering.

Other signs of this state include:

• Waking in the early hours and being unable to get back to sleep

• Feeling a sudden, disproportionate surge of stress in response to small things

• Difficulty concentrating or making decisions, even simple ones

• A flat, heavy feeling that isn't quite sadness but isn't okay either

• Physical tension held in the jaw, shoulders, or stomach

• Appetite that feels dysregulated, either absent or hard to satisfy

None of these are character flaws. They are physical symptoms of a nervous system that has been working too hard for too long.

You need to send the nervous system a physical signal that it is safe to shift down. And the most direct, accessible route to doing that runs through your breath.

Why You Can't Just Decide to Relax

This is worth saying directly, because many people in this state try very hard to relax and feel frustrated or even more anxious when they can't.

The rest-and-recover setting of your nervous system is not under direct conscious control. You cannot think your way into it, or decide to be calm, or tell yourself to stop being stressed. The alert system operates below the level of thought. It responds to physical signals, not instructions.

This is why distraction, willpower, or simply trying harder do not work when the body is stuck in alert mode. You need to send the nervous system a physical signal that it is safe to shift down. And the most direct, accessible route to doing that runs through your breath.

The Breath as a Switching Mechanism

Your breathing is the one part of your body's automatic functioning that you can also consciously control. And here is why that matters: the way you breathe directly influences which setting your nervous system is in.

When you breathe in, your heart rate rises slightly. When you breathe out, it slows. This is a well-documented physiological phenomenon called respiratory sinus arrhythmia, though all you need to know is this: the out-breath activates the calming side of your nervous system. The in-breath activates the alert side.

This means that the ratio of your inhale to your exhale is not a neutral thing. A short, shallow breath with a quick exhale keeps the alert system running. A longer exhale than inhale begins to tip the balance the other way.

This is the basis of the extended exhale: deliberately breathing out for longer than you breathe in. It is not a relaxation technique in the soft, optional sense. It is a direct physiological intervention. You are using the mechanics of your own breathing to send a clear signal to your nervous system: the threat has passed; it is safe to come down.

Going Further: Coherence Breathing

If the extended exhale is the first tool, coherence breathing is the deeper practice.

Coherence breathing means breathing at a slow, steady, consistent rate: typically around five to six breath cycles per minute (5 seconds inhale, 5 seconds exhale). At this rate, your breathing, heart rate, and blood pressure begin to move in a smooth, rhythmic pattern together. Researchers sometimes call this state heart rate variability coherence, though you don't need to remember that. What you need to know is what it feels like: a gradual softening of the physical tension in the body, a slowing of thought, a sense of the dial beginning to move.

Unlike the extended exhale, which can work within a minute or two, coherence breathing tends to work more gently and more deeply over five to ten minutes of consistent practice. The two approaches complement each other well: use the extended exhale when you need to interrupt an acute stress response quickly, and use coherence breathing when you have a little more time and want to genuinely shift your baseline.

How to Do It: A Simple Guide

For immediate use: the extended exhale

Breathe in through your nose to a count of four. Breathe out slowly to a count of six or eight. The exhale should feel unhurried, like you are breathing out through a small gap rather than releasing all at once. Repeat for six to eight cycles.

This is enough to begin lowering your heart rate and reducing the physical experience of being on alert. It works in a waiting room, in a parked car, in the two minutes before a difficult call.

For deeper recovery: coherence breathing

Find a position where your body is supported and your back is reasonably straight. Breathe in to a count of five. Breathe out to a count of five. Keep the rhythm as smooth and even as you can. There should be no pause at the top or bottom of the breath. Continue for five to ten minutes.

If counting feels effortful, there are free coherence breathing audio guides and apps that provide a gentle prompt to breathe with. Many people find these easier to use, especially when tired.

A note on timing: coherence breathing is most effective when done consistently, ideally at the same time each day, rather than only in moments of acute stress. Many people find that ten minutes in the morning and ten minutes before sleep begins to shift their overall stress baseline within two to three weeks of regular practice - but give it longer, as extensive trauma can make the body stubborn to let go. Hard, I know.

The Bigger Picture

Chronic stress changes the body gradually, and recovery from it also takes time. The nervous system does not reset overnight, particularly after a long period under sustained pressure. It rebuilds in small increments, with repetition and consistency.

What the extended exhale and coherence breathing offer is not a shortcut. They are a way of reliably, repeatedly sending your nervous system the signal it needs to begin the process of coming down. Every time you use them, you are reinforcing a different pattern. Over time, that new pattern becomes the nervous system's default.

Of course, this needs to be done in the context of stabilising your life, getting emotional safety and addressing complex trauma (which we support in the renurture programme) - but shouldn't be overlooked either. Whilst there is psychological healing to do, the body needs this type of help to break out of a biological habit of being over-active, most of the time.

I regularly hear clients say how much they like this part of the work, although be mindful that breathwork can sometimes cause you to panic more. Find out more on this here, and what to do about it.
