Stress isn't just something you feel. It's something your body experiences—and understanding how it works is the first step towards managing it.

We've all heard the phrase, "I'm just stressed."

But stress is far more than a busy schedule or a difficult week.

It's a biological response designed to protect you.

The challenge is that our bodies evolved to handle short bursts of stress, not the constant stream of emails, deadlines, family responsibilities, poor sleep, financial pressures, and endless notifications that many women face today.

For women over 35, this ongoing stress can feel even more noticeable as hormonal changes begin to influence how the body responds and recovers.

One of the key players behind this process is a hormone called cortisol.

Despite often being labelled the "bad hormone," cortisol isn't the enemy.

In fact, you couldn't live without it.

The goal isn't to eliminate cortisol—it's to help your body regulate it naturally.

What Is Cortisol?

Cortisol is a hormone produced by your adrenal glands, two small glands that sit on top of your kidneys.

It's released as part of your body's natural stress response through a communication network known as the hypothalamic-pituitary-adrenal (HPA) axis.

When your brain perceives a challenge—whether it's a genuine emergency or an important presentation—it signals the release of cortisol.

This hormone helps your body respond by:

• Increasing available energy
• Raising blood sugar temporarily
• Supporting blood pressure
• Improving alertness
• Helping regulate inflammation
• Mobilising stored fuel for muscles and the brain

In the right amount, at the right time, cortisol is incredibly helpful.

It's part of what gets you out of bed in the morning, keeps you focused during an important meeting, and helps you respond quickly in unexpected situations.

Stress Isn't Always Bad

Not all stress is harmful.

Scientists often distinguish between:

Acute stress

This is short-term stress.

Examples include:

• Giving a presentation
• Running to catch a train
• Completing a workout
• Taking an exam

Your cortisol rises temporarily and then returns to normal once the challenge has passed.

This is a healthy and natural response.

Chronic stress

This is when stress continues for weeks, months, or even years.

Examples include:

• Ongoing work pressure
• Caring for children or ageing parents
• Financial concerns
• Poor sleep
• Relationship difficulties
• Constant multitasking

Instead of switching off, the stress response stays activated more often than it should.

Over time, this can affect how you feel physically and emotionally.

Why Stress Can Feel Different After 35

Around your mid-thirties and into perimenopause, estrogen and progesterone begin to fluctuate.

These hormones don't only influence reproductive health.

They also interact with the brain, nervous system, sleep, mood, and stress response.

Many women notice that situations they once handled easily now feel more overwhelming.

You might recognise experiences such as:

• Feeling mentally "wired" at night
• Waking at 3 a.m. and struggling to fall back asleep
• Feeling exhausted but unable to relax
• Becoming more emotionally reactive
• Taking longer to recover from busy periods

These experiences are common during hormonal transition, although every woman's experience is unique.

How Cortisol Affects the Body

Cortisol influences almost every major system in the body.

Energy

In the short term, cortisol increases available energy by encouraging the release of glucose into the bloodstream.

This is useful during genuine challenges.

However, when stress becomes chronic, some people notice fluctuating energy throughout the day.

Sleep

Healthy cortisol follows a daily rhythm.

It is naturally:

• Highest in the morning
• Gradually decreases during the day
• Lowest during the evening

When this rhythm becomes disrupted, falling asleep—or staying asleep—may become more difficult.

Poor sleep can also increase perceived stress the following day, creating a cycle that's difficult to break.

Appetite

Many people notice changes in appetite during stressful periods.

Some lose interest in food.

Others crave highly processed, sugary, or salty foods.

This isn't simply about willpower.

Stress influences hormones involved in hunger, satiety, and food reward.

Muscle and Recovery

When stress is short-lived, the body recovers well.

During prolonged periods of stress, recovery after exercise may feel slower.

That's one reason why adequate protein, regular movement, and sufficient rest become increasingly important after 35.

Mood and Focus

Cortisol helps improve alertness in the short term.

But when stress becomes constant, some people experience:

• Mental fatigue
• Difficulty concentrating
• Feeling overwhelmed
• Reduced motivation

Again, this doesn't happen because cortisol is "bad."

It reflects the body's attempt to adapt to ongoing demands.

Signs You May Be Under Too Much Stress

Stress doesn't always look dramatic.

Sometimes it appears as small changes that gradually become normal.

These might include:

• Feeling tired despite sleeping
• Constant muscle tension
• Frequent headaches
• Feeling "busy" even when resting
• Reduced patience
• Digestive discomfort during stressful periods
• Afternoon energy crashes
• Difficulty switching off at night

These symptoms can have many different causes, so they're not specific to cortisol alone.

If symptoms persist or significantly affect daily life, it's important to speak with a healthcare professional.

Can You Test Your Cortisol?

You may have seen at-home cortisol tests promoted online.

In reality, cortisol naturally changes throughout the day.

Because of this, a single measurement often provides limited information.

Healthcare professionals may recommend blood, saliva, or urine testing in specific medical situations, particularly when investigating suspected hormone disorders.

For everyday stress, focusing on healthy habits is usually more useful than trying to optimise a single cortisol number.

Supporting a Healthy Stress Response

You can't eliminate stress completely.

But you can build habits that help your body recover more effectively.

Prioritise Sleep

Sleep is one of the most powerful ways to support a healthy stress response.

Aim for:

• A consistent bedtime
• A cool, dark bedroom
• Limiting screens before sleep
• Morning daylight exposure to support your body clock

Eat Regular, Balanced Meals

Skipping meals or relying on ultra-processed snacks may leave you feeling less energised.

Focus on meals that include:

• Protein
• Healthy fats
• Fibre-rich vegetables
• Whole-food carbohydrates that suit your lifestyle

Balanced nutrition supports steady energy throughout the day.

Move Your Body

Exercise is one of the best tools for managing stress.

The key is balance.

Strength training, walking, yoga, cycling, swimming, and other enjoyable activities all contribute to long-term wellbeing.

Remember:

More exercise isn't always better.

Recovery is part of fitness.

Support Your Nervous System

Small daily habits can help signal safety to your brain.

Examples include:

• Deep breathing
• Meditation
• Time in nature
• Reading
• Gentle stretching
• Journaling
• Spending time with people who make you feel supported

Even a few minutes each day can help create moments of calm.

Reduce the "Always On" Lifestyle

Modern life encourages constant stimulation.

Try creating small boundaries, such as:

• Turning off non-essential notifications
• Taking screen-free breaks
• Avoiding work emails late at night
• Scheduling time with no agenda at all

Rest isn't something you earn.

It's something your body needs.

Where Nutrition Fits In

No single food or supplement can "fix" stress.

However, a nutrient-rich diet provides the building blocks your body needs to function well.

Key nutrients involved in normal nervous system and energy function include:

• Magnesium
• Omega-3 fatty acids
• B vitamins
• Vitamin D
• Protein

These nutrients work best as part of an overall healthy lifestyle—not as quick fixes.
