How Stress Is Draining Your Energy (And What to Do)

Intro

Stress has become such a normal part of modern life that many people no longer even recognise when they are stressed. We describe ourselves as “busy”, “flat out”, “mentally drained”, or “just tired” — but rarely stop to think about what is actually happening underneath the surface physiologically. And this matters, because stress is not simply an emotional feeling or a bad day at work - It is a full-body biological process that affects nearly every system inside the human body.

In small amounts (Acute stress), stress is completely normal and can even be beneficial. Stress can sharpen focus, increase alertness, improve reaction speed, and help us respond to challenges effectively. Humans evolved with stress for a reason. The body’s stress response was designed to help us survive difficult situations by temporarily increasing performance and keeping us alert to danger (fight or flight).

The issue is not stress itself. The issue is that the modern world rarely allows stress to switch off. Instead of short bursts of challenge followed by proper recovery, many people now live in a near constant state of:

• stimulation

• urgency

• notifications

• work pressure

• financial stress

• emotional overload

• poor sleep

• information overload

  
  

This is called chronic stress (and more accurately, chronic low grade stress – meaning it can exist subtly in and amongst everyday life).

And whilst the body is incredibly adaptable in the short term, it was never designed to remain in “high alert mode” all day, every day. Over time, chronic stress quietly drains:

• physical energy

• mental clarity

• motivation

• sleep quality

• food quality

• recovery capacity

  
  

This is one of the hidden reasons so many people feel exhausted despite:

• sleeping more

• drinking more caffeine

• trying to “push through”

• constantly searching for productivity hacks

  
  

The body is not lazy. The system itself has simply become overloaded.

The good news is that stress management does not require completely changing your life overnight. In fact, many of the most effective strategies are surprisingly simple once you understand what stress is actually doing to your body.

What Is Stress — And How Do We Get It?

At its core, stress is the body’s response to challenge, pressure, or perceived threat. When the brain detects something stressful, it activates a series of systems designed to help you survive and respond quickly. This is often referred to as the “fight or flight” response — a deeply wired biological system that humans have relied on for survival throughout evolution (Lion, fear of death, run!).

When this system activates, the brain signals the release of stress hormones such as adrenaline and cortisol. These hormones temporarily increase alertness, raise heart rate, mobilise stored energy, and prepare the body for action. At the same time – processes less required for immediate survival: digestion, reproduction, going to the loo – these are all dampened down to make room for this action.

From an evolutionary perspective, this system was incredibly useful. Thousands of years ago, stress responses helped humans survive predators, food scarcity, environmental danger, and physical threats.

The problem is that modern stress looks very different from the stress humans originally evolved around, but the process and impacts internally are still the same.

The brain does not always distinguish particularly well between: “physical danger” and “psychological pressure.” So even though you are not physically fighting for survival, your body may still activate stress physiology repeatedly throughout the day.

And importantly, stress is not just “in your head.” Stress affects:

• hormones

• digestion

• appetite

• blood sugar regulation

• sleep quality

• immune function

• recovery

• nervous system regulation

• energy production

  
  

This is why stress often feels physical as much as emotional. The body is not simply “feeling stressed.” It is responding biologically to pressure.

And when that biological response stays switched on for too long, energy begins to suffer.

Acute vs Chronic Stress (And Why Stress Is Such a Problem Today)

Not all stress is harmful. In fact, short-term stress — known as acute stress — can actually be beneficial. As we have touched on above - Acute stress helps us stay alert, focused, motivated, and capable of handling immediate challenges. In many situations, it can even improve performance temporarily by increasing attention and energy output.

Examples of acute stress might include:

• exercising

• public speaking

• taking an exam

• playing competitive sport

• handling an important deadline

  
  

In these situations, stress hormones rise temporarily and then return back down once the challenge has passed. This is healthy physiology. The body responds, adapts, and recovers.

The issue today is that many people no longer experience stress in short bursts followed by proper recovery. Instead, they experience: low-grade chronic stress.

When the stress response remains activated for extended periods of time without sufficient recovery, we call this chronic stress. And this is where the modern world becomes such a challenge. Many people wake up already stressed before the day has even properly started:

• poor sleep

• immediate phone checking

• rushing

• caffeine dependence

• work pressure

• information overload

  
  

Then the stress simply continues:

• constant notifications

• multitasking

• sitting indoors all day

• poor nutrition

• emotional pressure

• financial worries

• overstimulation

  
  

The nervous system rarely gets a genuine opportunity to fully slow down and this creates a state where the body remains constantly prepared for something to happen. There is no rest bite, there is no switch off.

And whilst this may feel productive temporarily, over time it becomes exhausting. The body can compensate remarkably well for a while. But eventually:

• sleep quality declines

• recovery suffers

• cravings increase

• focus worsens

• energy crashes become more common

  
  

This is a bit I imagine you can relate to strongly. We’ve all stared at the screen trying to get something done and just had, well, nothing left. Or sat in bed just unable to rest and switch off.

This is why chronic stress has become one of the biggest hidden drivers of low energy in modern life. The problem is not that humans experience stress.

The problem is that modern life often delivers: high stress, with very little recovery.

How Stress Impacts Energy

One of the biggest misconceptions about stress is that it is purely mental. In reality, stress is physically demanding. Every time the stress response activates, the body shifts resources toward immediate survival and performance. Stress hormones help release stored energy into the bloodstream so the body can react quickly and stay alert.

Initially, this can even feel energising. Some people describe stress as:

• “running on adrenaline”

• being “wired”

• constantly switched on

• surviving on momentum

  
  

But this is not stable energy. It is stress-driven stimulation. And stimulation always comes with a cost eventually.

Over time, chronic stress increases the body’s overall physiological load. The nervous system remains highly activated, recovery becomes impaired, and the body begins using significant resources simply trying to maintain balance internally. This often creates a form of exhaustion that feels deeper than simply “being tired.”

In this state, people commonly experience:

• mental fatigue

• emotional exhaustion

• poor concentration

• low motivation

• disrupted sleep

• physical tiredness

  
  

Stress also heavily impacts the nervous system itself.

The body operates through two broad nervous system states: “fight or flight” (sympathetic) and “rest and digest” (parasympathetic). This is healthy biology and the body actively needs both – the issue is staying in one state (often fight or flight) for too long.

The sympathetic system helps us: perform, react, stay alert, handle danger, act, survive.

The parasympathetic system helps us: recover, digest, repair, rest, regulate and re-vitalise.

So, when we spend our time in ‘go mode’ always, what you do think happens? Breakdown. Not rapidly (although, in some cases), but over time. Have you ever known anyone take along overdue holiday and then get unwell? Well, this is stress activation out of hand meeting recovery and the body going ‘ok now we need to process’ and the result is: illness, exhaustion and sleep.

Constant stimulation means the body rarely fully enters recovery mode. And the body cannot stay in survival physiology forever without consequences.

Stress also commonly impacts digestion. When the body is highly stressed, digestion is often deprioritised because survival systems take temporary priority. Over time this may contribute to:

• bloating

• digestive discomfort

• inconsistent appetite

• poor hunger regulation

• reduced digestive efficiency

  
  

And if digestion becomes impaired, nutrient absorption and energy regulation may also suffer. This creates another hidden pathway through which stress drains energy.

The body is not just mentally tired. It is physiologically overloaded.

A Modern Stress Problem: Cognitive Overload & Constant Stimulation

One of the biggest differences between modern stress and historical stress is the sheer volume of mental stimulation people now experience every single day. The human brain was never designed to process the endless stream of information that modern life now delivers continuously.

Think about it - Many people today have:

• phone notifications (immediately upon waking up)

• emails

• meetings

• social media

• messages

• streaming

• news

• constant screen exposure

  
  

…without any meaningful mental recovery. This creates what is often referred to as:cognitive overload. The brain is constantly switching attention between tasks, processing information, making decisions, and reacting to new inputs. Even when sitting physically still, the nervous system may remain highly active internally.

And this is mentally exhausting.

Many people never truly allow themselves to slow down mentally anymore. Think about how often modern life looks something like this:

• wake up → phone

• breakfast → screens

• work → notifications

• breaks → scrolling

• evening → TV + phone

• bed → more stimulation

  
  

The nervous system rarely experiences silence.

And whilst stimulation itself is not automatically bad, constant stimulation without recovery gradually increases stress load over time.

How Stress Affects Food Choices (And Then Energy)

One of the most overlooked effects of stress is how strongly it influences eating behaviour. When people are stressed, food choices often become less intentional and far more reactive. This is important because stress and nutrition often feed directly into one another in both positive and negative ways.

Stress hormones can increase cravings for: Sugar, processed foods, comfort, fast solutions, high-fat convenience. Partly this is because the brain is looking for quick energy, comfort and dopamine stimulation.

Stress also reduces patience, planning and decision-making capacity. The battery is drained and we need fast action now. So we reach for what’s easy, what’s convenience and what might provide a momentary relief from the stress itself. All very natural human behaviour.

This means even people who normally eat relatively well may suddenly find themselves:

• skipping meals

• relying heavily on caffeine

• emotionally eating

• grabbing convenience foods

• overeating late at night

  
  

Unfortunately, many of these food patterns then worsen energy further. And the result can be devastating:

stress → poor food choices → worse energy → more stress.

A cycle many people become trapped inside without realising it.

5 Simple Ways To Reduce Stress (Starting Today)

The good news is that stress management does not always require massive life changes. In fact, some of the most effective strategies are surprisingly simple because they focus on supporting the body’s core recovery systems consistently over time.

Stress management is often less about “doing more” and more about removing some of the constant pressure the nervous system is already under.

Small consistent changes matter. Especially when repeated daily.

1. Improve Sleep Consistency

Sleep is one of the body’s primary recovery systems. Poor sleep increases stress sensitivity dramatically and reduces the body’s ability to regulate emotions, recovery, focus, appetite, and energy properly.

The best thing to do is try to work on your sleep:

Focus on:

• consistent sleep times daily (even on the weekends)

• reducing screens before bed (2 hours before if possible)

• limiting caffeine later in the day (minimal from 1pm onwards usually works)

• creating calmer evenings (no late work, no big late meals)

  
  

Better sleep improves stress resilience enormously.

2. Eat More Balanced Meals

The body handles stress far better when properly fuelled. Balanced meals that are nutritionally balanced (read our blog here for the low down) and contain protein, whole form carbohydrates, fibre and healthy fats – these all help stabilise blood sugar and support stable energy throughout the day

Remember: Food is not just calories. It is support for the nervous system.

3. Move Your Body Daily

Movement is one of the most effective ways to regulate stress physiology naturally. Exercise helps improve mood, regulate stress, support sleep and improve energy regulation.

Early morning movement (put the phone down, go for a walk) can work wonders for stress relief.

And we are not talking massive workouts necessarily – 10 mins walking, yoga or stretching can also be highly effective.

Structuring your week something like this could be a game changer:

• Daily 10 mins light movement, first thing

• Regular 5 min walks in between work tasks through the day

• 3 or 4 workouts that are structured spread across the week

4. Reduce Constant Stimulation

Many people never allow the nervous system to properly slow down. Phones, social media, notifications, and constant information create ongoing mental activation throughout the day.

To tackle this try creating:

• screen-free periods

• quieter mornings

• device-free walks

• reduced notifications

• moments of stillness

  
  

The nervous system needs periods of calm too. And in our over stimulated world, this can be challenging – but getting into a flow of calm and stimulation free periods is really life changing.

5. Stop Glorifying Exhaustion

Modern culture often celebrates being exhausted. Over stretching to meet unrealistic deadlines and impress someone else. Burning the candle at both ends. This is not a healthly long term practice

Constantly overriding exhaustion with:

• caffeine

• pressure

• stimulation

• stress

  
  

…usually creates bigger problems later. So challenge yourself to think ‘am I creating enough periods of rest and recovery here?’ when you think about your goals.

A helpful tool is to structure your day into chunks, such as:

1.     Protect and prioritise this: 90% commitment (critical work, non negotiable sleep times, family time)

2.     70% is enough: Big projects, training goals, future ‘you’ stuff

3.     Let life exist naturally: time to live, be, rest, recovery

Making small tweaks, and stopping the glorification of work – this can be extremely powerful and often leads to a longer term approach that you can actually stick to.

Recovery is not laziness. It is biology. Long-term energy depends on it.

Closing

Stress is not just an emotional experience. It is a physiological demand placed on the body.

And whilst short-term stress can sometimes improve performance temporarily, chronic stress quietly drains:

• energy

• recovery

• sleep quality

• focus

• digestion

• nervous system resilience

• overall wellbeing

  
  

The modern world often traps people inside a cycle of:

stress → overstimulation → poor recovery → low energy → more stress.

But the solution is rarely found in extremes or complicated “life hacks.” Most people do not need more intensity. They need:

• better recovery

• better nourishment

• better sleep

• less overstimulation

• more balance

• more intentional recovery

  
  

Because real energy is not built through constantly forcing the body harder. It is built through supporting the systems that allow the body to: recover, repair, regulate and function properly in the first place.
