Your Body Is Listening
A midlife guide to light, food, movement, hormones and the signals that help us thrive
There is something I find incredibly fascinating about the human body.
It is constantly listening.
Not just to what we eat.
It is listening to light, movement, sleep, stress, temperature, food, exercise, rest and our environment.
And during midlife, I think this becomes particularly important.
Because somewhere around our 40s and 50s, our bodies begin to change.
Our hormones fluctuate. Our sleep can change. Muscle becomes harder to maintain. We may notice changes in where we store fat, how we respond to food, how quickly we recover from exercise and how resilient we feel.
And it can be very tempting to think:
"What am I doing wrong?"
But perhaps a better question is:
"What is my body asking for now?"
That is the question I want to explore.
Your hormones don't work in isolation
We often talk about oestrogen and progesterone as though they are the whole story of midlife.
They aren't.
Our reproductive hormones are part of a much bigger conversation involving the brain, hypothalamus, nervous system, metabolism, sleep and our circadian rhythm — our internal body clock.
And this is where something as simple as light becomes surprisingly interesting.
Your brain has a master circadian clock in an area called the suprachiasmatic nucleus, within the hypothalamus.
It receives information about light through the eyes and helps coordinate daily rhythms throughout the body.
Think of it as one of the body's timekeepers.
It helps your body understand:
It's daytime. Be alert.
And later:
It's nighttime. Begin winding down.
This influences sleep, hormone signalling, metabolism and many other biological processes.
So your morning routine isn't simply about getting a bit of fresh air.
Morning daylight is information.
Step outside before you scroll
One of the simplest things you can do for your circadian rhythm is to get outside during the morning.
You don't have to stand in direct sunshine.
You don't have to meditate on a mountain.
You don't have to buy a special lamp.
Just step outside.
Let your eyes experience natural daylight.
Have your morning walk.
Take the dog out.
Stand in the garden with your first drink of the day.
Open the door and breathe.
And if you can combine that daylight with some gentle movement, even better.
It is such a simple habit, but it gives your brain a very clear daytime signal.
And later, we can do the opposite.
Dim the lights.
Slow things down.
Reduce stimulation.
Create darkness.
Because your body needs a strong night-time signal too.
Light isn't just about seeing
This is one of the areas of modern health that I find particularly fascinating.
We tend to think of light as something that helps us see.
But light is also a biological signal.
Our bodies evolved in an environment where daytime was bright and nighttime was dark.
Modern life has rather blurred those boundaries.
We can sit indoors under artificial light all day and then spend the evening surrounded by bright screens, lights and stimulation.
This doesn't mean we need to become frightened of our phones or obsess about blue light.
It means we can simply ask:
Am I giving my body enough daytime light and enough nighttime darkness?
That is a much more useful question.
And then there are the mitochondria...
You may have heard mitochondria described as the powerhouses of the cell.
It's a bit of a cliché, but it is useful.
Mitochondria help convert energy from the food we eat into ATP — the energy currency our cells use to perform their many jobs.
And here's where midlife gets really interesting.
Because one of the best things we can do for our metabolic health isn't necessarily to eat less.
It is to maintain and build muscle.
Muscle is metabolically active tissue.
It uses glucose.
It requires energy.
It helps us remain strong and physically capable.
And as we get older, maintaining muscle becomes increasingly important for strength, metabolic health, mobility and independence.
Which is why I am becoming increasingly passionate about women in midlife lifting things.
Not because we need to look a certain way.
Because we need our bodies to remain capable.
Muscle is one of your midlife superpowers
You don't need to become a bodybuilder.
You don't need to spend hours in the gym.
But your muscles need a reason to stay.
That might be:
resistance training
Pilates
carrying shopping
lifting weights
using resistance bands
climbing stairs
getting up and down from the floor
gardening
walking uphill
practising balance
Your body adapts to what you ask it to do.
So give it a reason to remain strong.
And remember:
Cardio is important. Strength is important. Mobility is important. Recovery is important.
It isn't an either/or.
Feed the muscle
This brings us to food.
Midlife isn't the time to live on coffee and a piece of toast because you're trying to lose weight.
(And if you're anything like me, coffee isn't even on the menu!)
Our nutritional priorities change.
Protein becomes particularly important because it provides the amino acids our bodies need to build and maintain muscle.
So rather than asking:
"How little can I eat?"
I would much rather ask:
"How well can I nourish myself?"
Aim to include a good source of protein at each meal.
Think:
Eggs
Greek yoghurt
Fish
Chicken
Lean meat
Cottage cheese
Beans
Lentils
Other protein-rich foods that work for you
And then build around it with vegetables, fruit, fibre, healthy fats and quality carbohydrates according to your individual needs.
You don't need a perfect diet
I don't believe in the idea that there is one perfect midlife diet.
There isn't.
Some women thrive on more carbohydrates.
Some prefer fewer.
Some eat meat.
Some don't.
Some love breakfast.
Some aren't hungry until later.
Our bodies, lifestyles and circumstances are different.
But there are some principles that make sense for most of us:
Eat enough protein.
Eat plenty of plants and fibre.
Include healthy fats.
Eat a variety of whole foods.
Stay hydrated.
Don't make ultra-processed foods the foundation of your diet.
And perhaps most importantly:
Stop making food another source of stress.
A nutritious diet doesn't have to be complicated.
What about carbohydrates?
This is another area where wellness advice can become unnecessarily polarised.
Carbohydrates aren't inherently bad.
Potatoes aren't bad.
Oats aren't bad.
Fruit isn't bad.
Beans aren't bad.
The bigger picture matters.
A bowl of sweets eaten alone is very different from potatoes served with salmon and vegetables.
A pastry eaten occasionally isn't going to undo a healthy lifestyle.
We don't need more food fear.
We need food literacy.
Learn how different foods make you feel.
Combine protein, fibre, healthy fats and carbohydrates in ways that support your energy and appetite.
And enjoy your food.
Don't forget the fats
Our brains are rich in fat, and certain fatty acids, including DHA, play important roles in brain and cell biology.
So healthy fats have a place in a nourishing midlife diet.
Think:
Extra virgin olive oil
Oily fish
Nuts
Seeds
Avocado
Eggs
Again, it's about the whole pattern rather than one magical food.
Your nervous system needs a say too
And this is where my own work with movement becomes particularly relevant.
We often talk about exercise as though the only goal is to make the body fitter.
But movement can also change how we feel.
Our nervous system is constantly responding to what is happening around us.
Busy day.
Poor sleep.
Work pressure.
Hormonal changes.
Too much exercise.
Not enough recovery.
Life.
And sometimes what we need isn't another intense workout.
Sometimes we need to come back into our body.
Slow down.
Breathe.
Move gently.
Notice tension.
Feel our feet.
Allow the shoulders to soften.
Let the movement become less about performance and more about connection.
This is one of the reasons I created Somalates®.
Movement doesn't always need to push us.
Sometimes it can help us find our balance.
Helping your body find its balance.
Midlife doesn't need more punishment
I think this is worth saying again.
You don't have to exhaust yourself to be healthy.
You don't have to do HIIT every day.
You don't have to run.
You don't have to take cold plunges.
You don't have to fast for 18 hours.
You don't have to eliminate carbohydrates.
You don't have to buy every supplement that promises longevity.
And you certainly don't have to start over every Monday.
Health is built from the things you can do repeatedly.
Think rhythm, not routine
This is something I talk about a lot.
Your body loves rhythm.
Morning light.
Daytime movement.
Regular nourishment.
Periods of activity.
Periods of recovery.
Evening calm.
Night-time darkness.
Sleep.
Then we begin again.
It isn't about doing everything perfectly.
It is about giving your body consistent signals.
The Midlife Biology Reset
If I could reduce all of this to a handful of simple messages, it would be these:
🌅 Give your body daylight
Get outside in the morning whenever you can.
💪 Build muscle
Challenge your muscles regularly.
🥚 Eat enough protein
Give your body the building blocks it needs.
🥦 Eat real, nourishing food
Prioritise protein, plants, fibre and healthy fats.
🚶 Move throughout the day
Your body was designed to move, not simply exercise for an hour and sit for eight.
❤️ Look after your cardiovascular fitness
Walking, cycling, swimming, dancing, Pilates and other activities all have their place.
🧘 Regulate and recover
Your nervous system needs both challenge and calm.
🌙 Protect your sleep
Darkness and a regular sleep rhythm matter.
💧 Hydrate
Water first. Consider electrolytes when there's a genuine reason, such as significant sweating or prolonged exercise.
🦴 Think about your bones
Strength, weight-bearing movement, protein, calcium and vitamin D all matter.
☀️ Respect the sun
Enjoy natural daylight, but don't deliberately burn or treat extreme sun exposure as a health intervention.
❤️ Stop trying to fix yourself
Your body isn't broken.
It is adapting.
Perhaps this is the real midlife reset
Maybe the answer isn't another diet.
Another detox.
Another 30-day challenge.
Another supplement.
Another rule.
Maybe the real shift is learning to understand the messages our bodies have been sending us all along.
Light tells us when to wake.
Darkness tells us when to rest.
Food provides the raw materials.
Muscle gives us strength and metabolic capacity.
Movement tells the body to remain capable.
Recovery gives us space to adapt.
Sleep restores.
Connection nourishes.
And our hormones are just one part of this incredibly complex conversation.
So perhaps, instead of asking:
"How can I get my old body back?"
we can start asking:
"How can I support the body I have now?"
Because midlife isn't the beginning of the decline.
It can be the beginning of a much deeper relationship with your body.
Less punishment.
Less perfection.
Less noise.
More nourishment.
More strength.
More awareness.
More rhythm.
More you.
And ultimately, that's what wellness means to me.
Not controlling your body.
Learning to listen to it.
A little Serendipity Wellness® reminder
You don't need to implement all of this tomorrow.
Choose one thing.
Perhaps tomorrow morning, step outside before reaching for your phone.
Take a walk.
Eat a proper protein-rich breakfast.
Lift something heavy.
Or simply take five minutes to breathe and move.
Then do it again.
Because the most powerful health interventions are often the ones that are simple enough to become part of your life.
Small signals. Repeated often.
That's where change begins.
