Why Stress Feels Harder During Perimenopause and Menopause

Many women tell me the same thing during perimenopause and menopause:

“I just don’t feel like myself anymore.”

They feel more anxious, emotionally reactive, overwhelmed, exhausted, forgetful or foggy. They may notice they are less patient, less motivated, more tearful, more irritable or suddenly struggling with stress they used to manage without a second thought.

And very often, they blame themselves.

They think they are failing, burning out, getting old, losing confidence or simply not coping.

But perimenopause and menopause are not just about periods stopping or hot flushes starting. They are whole-body hormonal transitions that can affect the brain, nervous system, mood, sleep, metabolism, pain, inflammation, memory, learning and stress resilience.

Hormones affect the brain too

Oestrogen and progesterone do far more than regulate the menstrual cycle.

They interact with neurotransmitters such as serotonin, dopamine, GABA, acetylcholine and noradrenaline. These chemical messengers are involved in mood, motivation, pleasure, memory, learning, focus, sleep and how we respond to stress.

So when hormones fluctuate or decline, it makes sense that women may feel mentally and emotionally different.

This is why some women suddenly experience anxiety, low mood, poor concentration, brain fog, reduced motivation, emotional overwhelm, irritability, poor sleep, loss of confidence or feeling tired but unable to switch off.

It is not “just in your head.”

It is physiology.

Why stress can make symptoms worse

When the body is under ongoing stress, it prioritises stress hormones such as cortisol and adrenaline.

That is useful in short bursts. It helps us respond to pressure, danger and demand.

But when stress becomes constant, the body can get stuck in survival mode.

This matters during perimenopause and menopause because oestrogen and progesterone help support the central nervous system.

Progesterone in particular has a calming effect for many women, and oestrogen influences mood, cognition and neurotransmitter function.

So you can end up in a vicious cycle.

Stress places more demand on the body. Hormonal changes reduce the buffer that previously helped you cope.

Sleep worsens. Blood sugar becomes more unstable. Inflammation may increase. The nervous system becomes more reactive.

Then stress feels even harder to manage.

This is why women often say:

“I used to cope with everything. Now the smallest thing tips me over.”

It is not just lifestyle, but lifestyle matters

I am always careful with this because women have spent far too long being told to “just lose weight,” “just relax” or “just go for a walk.”

That is not good enough.

Perimenopause and menopause involve real hormonal changes, and for the majority of women, body-identical HRT can be hugely beneficial, not only for symptom management but also for long-term health.

But lifestyle still matters.

Not because symptoms are your fault, but because your nervous system, hormones, metabolism and inflammation are all affected by the environment you live in every day.

Things that can add pressure include:

• chronic stress

• poor sleep

• dehydration

• sedentary behaviour

• highly processed foods

• high alcohol intake

• poor recovery

• endocrine disrupting chemicals

• pesticides and herbicides

• hormones used in some intensively farmed animal products

• plastics

• cleaning products

• skin and hair products

• unfiltered tap water

Endocrine disrupting chemicals are now found in many parts of modern life and can interfere with hormone signalling within the body. Some can mimic oestrogen and may contribute to hormone imbalance and inflammation in some women.

This does not mean we need to live in fear of everything.

But it does mean small changes can help reduce the overall load on the body.

Food, fasting and inflammation

Diet is not about restriction or punishment. It is about reducing inflammation, stabilising energy and supporting the body through a major hormonal transition.

Anti-inflammatory approaches can be helpful for many women. This may include a Mediterranean-style diet or a lower carbohydrate or ketogenic approach.

For some women, a lower histamine approach may also help where there are signs of histamine intolerance.

Intermittent fasting can also help some women because of its potential anti-inflammatory effects, but it needs to be used sensibly.

For many women, fasting for longer than 16 hours is not ideal, especially in the week before a period when the body may be more sensitive to stress, blood sugar changes and hormonal shifts.

This is why personalisation matters.

What helps one woman may make another feel worse.

Small changes can make a big difference

You do not have to overhaul your entire life overnight.

In fact, that often creates even more overwhelm.

Start by tracking patterns for a few weeks to see whether there are links between your symptoms and certain foods,

stress levels, alcohol, sleep, hydration,

your menstrual cycle or lifestyle habits.

Then choose just one thing to focus on first until it becomes second nature and part of your routine.

Notice:

• sleep quality

• stress levels

• hydration

• alcohol intake

• food choices

• energy dips

• mood changes

• anxiety

• brain fog

• histamine-type symptoms

• recovery after busy days

• symptoms before your period, if you are still cycling

Here are some ideas that may help support the nervous system and overall wellbeing:

• setting an alarm to remind you to drink water

• filtering your tap water

• avoiding drinking from plastic bottles where possible or looking for BPA-free bottles

• not heating food in plastic containers

• choosing glass or stainless steel when practical

• swapping some highly processed foods for whole foods

• adding more protein and healthy fats to meals

• reducing alcohol if symptoms flare afterwards

• walking outside in daylight

• low to moderate intensity exercise

• strength and resistance training two to three times per week

• breathwork or meditation before bed

• building a more consistent sleep routine to support circadian rhythm

• dancing around the kitchen to your favourite music

• a relaxing bath

• creative hobbies such as colouring, crafting, painting, music or gardening

• building proper recovery and downtime into your week without guilt

HRT and lifestyle are not either/or

While lifestyle changes can help reduce symptoms, and can really help women who are unable to take or choose not to take body-identical HRT, they do not replace hormone production or the potential long-term benefits that hormones can provide.

But equally, just because you are taking HRT, it does not mean it gives you a free pass to ignore the things that could improve your current lifestyle, stress levels, nervous system regulation and overall health.

The best outcomes often come from understanding the whole picture.

I’ll link separately to a full explanation of body-identical HRT, because this is still an area surrounded by outdated, confusing and fear-based information.

You are not failing

If you suddenly stop feeling like yourself in midlife, please do not dismiss it.

Do not assume you are weak.

Do not assume you are just stressed.

And do not assume you simply have to put up with it.

Perimenopause and menopause can affect the brain, nervous system and whole body. Understanding that earlier gives women the chance to seek the right support, make informed choices and stop blaming themselves for symptoms that have a physiological basis.

Your symptoms are real.

Your body is changing.

And the earlier you understand what is happening, the more options you have.

And you are definitely not alone.
