2 / Wired, Tired and Foggy? Where to Start

In the first article, we looked at why sleep problems, stress and brain fog so often arrive together. Hormonal changes can contribute, but they sit inside a much bigger system involving circadian rhythm, sleep quality, thermoregulation, the nervous system, metabolic health and everything else happening in your life.

Now we need to make that information useful.

If you are exhausted all day but suddenly wide awake when your head hits the pillow, waking repeatedly through the night or struggling to think clearly by lunchtime, I don't want you starting with ten supplements and a complicated evening routine. First identify the dominant problem. The woman who cannot fall asleep needs a different starting point from the woman who sleeps for eight hours but wakes exhausted.

First, work out what your sleep problem actually is

Before trying to improve your sleep, spend a week observing it. What time do you go to bed? Roughly how long does it take you to fall asleep? How often do you wake? What seems to wake you? How quickly do you fall asleep again? What time do you wake in the morning, and most importantly, how do you feel when you wake?

Also note caffeine, alcohol, exercise, evening meals, hot flushes, pain and significant stress. You don't need a sophisticated sleep tracker. In fact, consumer sleep devices can sometimes make people more anxious about achieving a perfect sleep score. We need the pattern, not another number to worry about.

The distinction matters because difficulty falling asleep, repeated awakenings, waking too early and waking unrefreshed are not necessarily the same problem.

If you cannot fall asleep, start with your body clock

If you regularly get into bed and remain awake for an hour or more, the first question is whether your biological clock and your chosen bedtime actually agree.

Your circadian system responds strongly to light. Getting outside into natural light in the morning helps reinforce the biological signal that the day has begun and supports appropriate circadian timing later that evening. Indoor lighting, even when it seems bright to us, is generally much less intense than outdoor daylight.

A reasonably consistent wake time is also surprisingly powerful. Many people focus entirely on bedtime, but wake time provides an important anchor for the circadian system. Sleeping until very late after a bad night can feel necessary, but repeatedly shifting the time you get up can make the following night's sleep more difficult.

Then look at your evening. Bright light, stimulating work and screens can all influence alertness, although screens are not the sole cause of modern insomnia. The bigger question is whether you are giving your brain a clear transition from active daytime behaviour to night.

You don't need a perfect two-hour wellness routine. You need a body that knows roughly when daytime ends.

Don't go to bed simply because you think you should

This sounds counterintuitive, but spending more time in bed is not always the solution to insomnia.

If you aren't sleepy at 9.30 pm but decide that you need eight hours and therefore must go to bed, you may spend the next two hours awake. Repeat that often enough and the brain begins associating bed with wakefulness, thinking, worrying and frustration rather than sleep.

Sleep requires sufficient sleep pressure, which builds while you are awake. Going to bed considerably earlier than your biological sleep drive can support may simply create more opportunity to lie awake.

Go to bed when you are genuinely sleepy rather than merely tired. Tired can mean physically exhausted, emotionally depleted or fed up with the day. Sleepy means you are struggling to keep your eyes open and your brain is ready to sleep.

That difference is surprisingly useful.

If your brain switches on in bed, stop trying harder to sleep

Few things are less effective than desperately trying to make yourself unconscious.

You notice that you are awake. You check the clock. You calculate how many hours remain before morning. Then you start thinking about how terrible tomorrow will be. Your heart rate increases slightly, your frustration rises and sleep becomes even less likely.

Over time, the bed itself can become associated with this state of alertness.

One of the principles used in cognitive behavioural therapy for insomnia, or CBT-I, is stimulus control. The aim is to rebuild the association between bed and sleep. If you are clearly awake and becoming increasingly frustrated, rather than remaining in bed fighting with your brain, get up and do something quiet in dim light. Return when you feel sleepy again.

This can feel completely wrong at first. But lying in bed for hours teaching your brain that bed is a place for worrying is not particularly useful either.

CBT-I deserves far more attention than sleep supplements

If insomnia has become persistent, CBT-I is one of the most evidence-based treatments we have. It is recommended as first-line treatment for chronic insomnia by major sleep and medical organisations.

CBT-I is much more than generic sleep hygiene. It combines approaches such as stimulus control, carefully adjusting time spent in bed, addressing unhelpful beliefs and anxiety around sleep, relaxation strategies and strengthening circadian and behavioural cues.

This matters because chronic insomnia can become self-perpetuating. The original trigger may have been hot flushes, a stressful period, illness or grief. Months later, that trigger may have improved while the sleep problem remains because the brain has learned a pattern of nighttime hyperarousal.

That is precisely where another magnesium supplement may be addressing the wrong mechanism.

If you fall asleep but keep waking, ask what is waking you

This is a different investigation.

Hot flushes and night sweats are obvious possibilities during the menopause transition. Pain, reflux, needing to urinate, alcohol, environmental noise, restless legs and sleep-disordered breathing can also fragment sleep.

If you wake hot and sweating several times a night, addressing vasomotor symptoms may be more effective than adding another sleep remedy. If reflux wakes you, work on the reflux. If you wake repeatedly to urinate, consider evening fluid intake, bladder symptoms and whether there is another reason for nocturia.

Sometimes women tell me they "sleep badly" when the real problem is that something keeps waking them. Identifying that something changes the entire strategy.

If you wake at 3 am, don't immediately blame cortisol

Middle-of-the-night waking is extremely common and has acquired an enormous amount of mythology online.

Brief awakenings between sleep cycles are normal. The problem is often not waking itself but being unable to return to sleep.

If this happens regularly, look at what preceded it. Alcohol is an important culprit because its initial sedative effect can be followed by more fragmented sleep later in the night. Hot flushes, pain, reflux and sleep apnoea can also cause awakenings. Stress can make the brain more likely to become highly alert once awake.

Then there is a very ordinary possibility: you may simply be spending too much time in bed. Someone going to bed at 9 pm and waking at 4 am has already had seven hours of opportunity for sleep.

A 3 am awakening is therefore a symptom to understand, not a cortisol diagnosis.

Caffeine deserves an experiment, not an argument

Caffeine blocks adenosine receptors and temporarily reduces the sensation of sleep pressure. Its effects can persist for many hours, and people differ substantially in how quickly they metabolise it.

You may genuinely be able to drink an espresso after dinner and fall asleep. That doesn't necessarily tell us whether caffeine is affecting the quality, depth or duration of your sleep.

If sleep is poor, make this easy. For two weeks, keep caffeine to the morning and see what happens. If nothing changes, you have learned something. If sleep improves, you have learned something considerably more useful than debating whether coffee is healthy.

And remember that caffeine isn't only in coffee. Tea, energy drinks, cola, chocolate and some medications can contribute too.

Alcohol is worth testing separately

The same experimental approach works with alcohol.

Alcohol can shorten the time it takes to fall asleep, which is why it can feel like an effective sleep aid. But as it is metabolised, sleep can become more fragmented, particularly during the second half of the night. It can also worsen snoring and obstructive sleep apnoea and may aggravate night sweats in some women.

If you regularly have wine in the evening and repeatedly wake during the night, remove alcohol for two or three weeks and observe the difference.

You are not making a lifelong decision about wine. You are conducting an experiment on your own physiology.

That is far more informative than assuming alcohol either is or isn't affecting you.

Wired and tired? If you wake exhausted, look beyond insomnia

This is an important fork in the road.

If you feel wired and tired, even after a full night in bed, it is worth looking beyond insomnia. The question is not simply how many hours you sleep, but whether your sleep is genuinely restorative.

If you spend seven or eight hours asleep but wake feeling unrefreshed, the question becomes less about how much sleep you are getting and more about what is happening while you sleep.

Obstructive sleep apnoea should move much higher on the list, particularly if you snore, wake choking or gasping, experience morning headaches, have high blood pressure or significant daytime sleepiness. Women can also present less typically, with insomnia, fatigue, mood changes and cognitive complaints.

Restless legs syndrome and periodic limb movements can disrupt sleep too. Restless legs typically produces an uncomfortable urge to move the legs, particularly during periods of rest and in the evening, and iron deficiency can contribute in some people.

Eight hours in bed cannot restore you properly if your sleep is being repeatedly interrupted by a physiological problem you don't know is happening.

Deal with hot flushes if they are destroying your sleep

This sounds obvious, but it is often missed.

A woman may spend months trying magnesium, melatonin, meditation apps, lavender sprays and elaborate bedtime routines while waking four times every night drenched in sweat.

At that point, the hot flushes are part of the sleep disorder.

There are hormonal and non-hormonal approaches to managing significant vasomotor symptoms, and the appropriate choice depends on the individual woman's health, preferences, symptom severity and medical history. Lifestyle factors such as alcohol, smoking, body weight and individual triggers may also influence symptoms.

The important point is that severe night sweats should not simply be accepted while you endlessly optimise "sleep hygiene." If a physiological symptom repeatedly wakes you, address the symptom.

Then look at what is happening during the day

Good sleep is not created only in the hour before bedtime.

Morning daylight, physical activity and regular meal timing all provide signals that help organise circadian physiology. Exercise can improve sleep quality and also supports mood, stress regulation, metabolic health and cognition.

If you are sedentary all day, consume caffeine to remain functional, eat irregularly and then expect your brain to suddenly understand at 10 pm that it is time for deep restorative sleep, you are asking a lot from your evening routine.

This is why I prefer to think of sleep as a 24-hour process.

What you do at 8 am can matter to what happens at 11 pm.

If stress is the dominant problem, identify the load before trying to calm yourself

When women say they need to "reduce stress," I sometimes wonder what that is supposed to mean in practical terms.

You cannot breathe your way out of caring for an elderly parent, financial pressure, an impossible workload or a relationship that is falling apart. Stress management cannot become another task women are expected to perform perfectly while nothing changes around them.

Start by separating stressors from the stress response.

Some stressors can be changed. Boundaries can be set, commitments removed, conversations had, workloads renegotiated or help requested. Others cannot currently be removed, in which case recovery becomes more important.

That recovery does not have to mean meditation. Walking, exercise, time outside, social connection, laughter, music, breathing practices, yoga or simply uninterrupted time without demands can all help shift the nervous system away from constant activation.

The question is not "Am I doing enough stress management?" It is "Where in my life does my nervous system actually get to stand down?"

Brain fog may improve when you stop treating the brain fog

If your concentration problems began at the same time your sleep collapsed, sleep becomes one of our first targets.

If you are eating irregularly, skipping meals, relying heavily on caffeine or experiencing significant glucose dysregulation, stabilising metabolic health may help.

If you are chronically stressed and trying to remember twenty things simultaneously, reducing cognitive load can matter too. Use lists. Put appointments in the calendar. Do one cognitively demanding task at a time when possible. This isn't admitting that your brain is failing. It is giving an overloaded brain fewer things to hold in working memory.

And if brain fog remains significant despite good sleep and reasonable stress management, that tells us something important too. It means we widen the investigation rather than continuing to blame sleep.

Don't automatically reach for a brain supplement

The supplement industry has discovered brain fog.

You will find products containing combinations of B vitamins, magnesium, adaptogens, mushrooms, herbs, amino acids and compounds promising focus, memory and mental clarity.

Some individual nutrients and compounds have legitimate physiological roles and some have interesting research. But that does not mean a multi-ingredient "brain formula" fixes the reason you cannot concentrate.

If you are iron deficient, correct the iron deficiency. If you are B12 deficient, correct B12. If sleep apnoea is fragmenting your sleep, treat the sleep apnoea. If your thyroid is underactive, investigate and manage the thyroid problem.

A supplement should solve an identified problem or have a clear therapeutic purpose. It should not become a substitute for finding out why your brain feels different.

What about magnesium and melatonin?

Both deserve more nuance than either "everyone needs them" or "they don't work."

Magnesium is essential for normal neurological and muscular function, but evidence for magnesium supplements as a general insomnia treatment remains limited and inconsistent. Correcting magnesium deficiency is sensible. Assuming every sleep problem is magnesium deficiency is not.

Melatonin is a hormone involved in circadian signalling rather than a traditional sedative. It can be useful in particular circadian rhythm problems and may help some people with sleep, but more is not necessarily better and timing matters. Taking a large dose at an arbitrary time because it says "sleep" on the bottle misses what melatonin actually does physiologically.

Neither supplement compensates for sleep apnoea, four nightly hot flushes, a bottle of wine, persistent pain or chronic insomnia that needs proper treatment.

Create your first two-week reset

Rather than changing everything tonight, choose the interventions that match your pattern.

Keep your wake time reasonably consistent and get outside into daylight early in the day. Move daily and exercise regularly according to your ability. If caffeine might be contributing, keep it to the morning for two weeks. If you drink alcohol regularly, try a period without it and observe your sleep. Avoid routinely eating a large meal immediately before bed and address obvious sleep disruptors such as reflux, pain or night sweats.

If you cannot fall asleep, don't simply spend longer in bed. If you repeatedly wake, identify what is waking you. If you wake exhausted despite apparently adequate sleep, consider whether sleep quality or sleep-disordered breathing needs investigating.

And if insomnia has persisted for months, look seriously at CBT-I rather than simply adding another sleep supplement.

This gives us something much more useful than a generic sleep routine: it gives us information about what your system responds to.

What I want you to take away from this

Sleep, stress and brain fog often reinforce one another, but you do not have to fix all three simultaneously. Find the dominant problem and start there. If hot flushes are destroying your sleep, address them. If your body clock is chaotic, stabilise it. If you sleep for eight hours and wake exhausted, investigate sleep quality. If chronic stress is keeping your brain permanently alert, look at both the stressors and where recovery can realistically happen.

Then observe what changes. The goal is not perfect sleep or a perfectly calm life. It is to remove the biggest physiological obstacles so your brain and nervous system can begin functioning more normally again. Once those foundations are in place, we can move to the next stage: deliberately building better sleep, greater stress resilience and stronger long-term brain health.
