Have you ever finished a conversation feeling unexpectedly drained?
Or spent an hour doing something seemingly simple, only to discover that you have very little capacity left for the rest of the day?
At other times, we may spend hours with someone, become absorbed in an activity, walk in nature, exercise, create something or simply have time alone — and notice that we feel more settled or restored afterwards.
We often describe these experiences in terms of energy.
While psychological energy isn’t something we can measure like the battery percentage on a phone, the language of energy can provide a useful way of noticing the demands placed upon our cognitive, emotional, physical and nervous-system resources.
I think of this as energy exchange: becoming curious about what our everyday experiences require from us, what they return to us, and what happens when that exchange becomes persistently unbalanced.
We Are Constantly Exchanging Energy With Our Environment
Every day involves demands on our available capacity.
Some are obvious.
Work requires concentration. Difficult conversations require emotional effort. Caring for others takes time and attention. Busy environments require sensory processing. Making decisions requires cognitive resources.
Other demands are much less visible.
You might be monitoring how someone else is feeling. Suppressing your own emotional response. Trying to appear calm when you feel overwhelmed. Navigating sensory discomfort. Switching repeatedly between tasks. Rehearsing a conversation in your mind. Worrying about something that hasn’t happened yet. Trying to meet expectations that don’t quite fit who you are.
These less visible demands can be particularly important because we may not recognise them as effort.
Yet effort is still occurring.
This is one of the ideas behind what I call our Personal Energy Economy — noticing not only what we do, but what it costs us to do it.
A simple way of thinking about this is:
Energy coming in − energy going out − invisible energy demands = available capacity
The aim isn’t to account for every unit of energy or eliminate everything that is demanding. Life inevitably asks things of us.
Instead, the aim is to become more aware of the exchange.
Not Everything That Takes Energy Is Bad
An important distinction is that energy expenditure is not necessarily a problem.
Some of the most meaningful parts of our lives require considerable energy.
Parenting can be exhausting and deeply valued.
Work can be demanding and purposeful.
Exercise uses physical energy but may support mood and wellbeing.
A challenging therapeutic conversation may leave someone tired while also contributing to important psychological work.
Learning something new can be cognitively demanding and enormously rewarding.
So the question isn’t simply:
“Does this take energy from me?”
A more useful question might be:
“What is the relationship between what this requires from me and what it gives back?”
Some experiences cost energy but provide meaning, connection, growth or satisfaction.
Others may continually draw from our resources without providing sufficient opportunity for recovery.
Over time, that distinction matters.
The Invisible Energy Leaks
Sometimes the largest demands on our energy aren’t the things other people can see.
Consider how much energy might be involved in:
- continually monitoring yourself in social situations;
- anticipating other people’s reactions;
- trying not to disappoint anyone;
- pushing through sensory overload;
- repeatedly switching attention;
- hiding distress;
- maintaining unrealistic standards for yourself;
- saying yes when you want to say no;
- replaying conversations afterwards;
- trying to function when your nervous system is already under strain.
For some neurodivergent people, there may also be substantial energy involved in navigating environments designed around different sensory, cognitive or social expectations.
For people who have experienced trauma, the nervous system may sometimes devote considerable resources to monitoring safety, anticipating threat or responding to reminders of previous experiences.
This doesn’t mean every experience of fatigue has a psychological explanation. Physical health, sleep, medication, hormones, nutrition and many other factors can influence energy and should not be overlooked.
It does mean that our internal experience can require energy even when very little appears to be happening from the outside.
What Gives Energy Back?
Understanding energy exchange also means becoming curious about restoration.
We sometimes think of rest simply as stopping work or getting more sleep.
Both are important, but restoration can take many forms.
For one person, restoration might involve solitude.
For another, connection.
It might be movement, music, creativity, time outside, laughter, reducing sensory input, completing something meaningful, spending time with someone with whom you don’t have to perform, or simply having a period in which nobody needs anything from you.
Importantly, what restores one person may drain another.
A busy social event may be energising for one person and exhausting for someone else. An empty weekend might feel wonderfully restorative to one person and isolating to another.
There isn’t a universally correct way to replenish.
The more useful task is learning to recognise your own patterns.
From Self-Judgement to Self-Attunement
When our capacity drops, it is easy to respond with judgement:
Why can’t I cope with this?
Everyone else seems to manage.
I should be able to do more.
I’m just being lazy.
But judgement rarely tells us what we actually need.
A different approach is self-attunement — becoming curious about our internal experience before deciding how we should respond to it.
We might begin by asking:
What am I noticing?
Then:
What might be contributing to this?
And finally:
What would support me now?
Sometimes the answer will be rest.
Sometimes it will be movement, connection, boundaries, nourishment, problem-solving, emotional processing or asking for help.
And sometimes we won’t immediately know.
The important shift is from automatically overriding our experience to becoming interested in what it might be communicating.
Conducting Your Own Energy Exchange Audit
Over the next week, try noticing how you feel before and after different activities, environments and interactions.
Rather than categorising things simply as good or bad, notice their effect on your available capacity.
You might ask yourself:
What tends to replenish me?
What predictably requires a lot from me?
Which demands are obvious, and which are largely invisible?
Are there particular people or environments where I expend considerable energy monitoring or adapting myself?
What happens when I have exceeded my available capacity?
What helps me recover?
You may begin to notice patterns that weren’t previously obvious.
The purpose isn’t to create another system for monitoring yourself perfectly.
It is to develop greater understanding.
Energy Is Also Relational
Our energy does not exist independently of the people and environments around us.
Relationships can provide safety, connection, humour, understanding and belonging. They can also require emotional labour, vigilance, accommodation or continual self-monitoring.
Healthy relationships are not relationships in which both people contribute exactly 50 per cent at every moment. Human beings move through periods of greater and lesser capacity.
What matters more is whether, over time, there is sufficient reciprocity, safety and space for each person to have needs.
Sometimes an important part of understanding our energy is noticing where we continually override ourselves in order to maintain connection.
That awareness can open conversations about boundaries, communication and what sustainable relationships might look like.
Sustainable Functioning, Rather Than Maximum Functioning
We live in a culture that often celebrates doing more.
More productivity. More commitments. More achievement. More availability.
But being capable of doing something doesn’t necessarily mean doing it repeatedly is sustainable.
A person may be able to push through exhaustion, sensory overload or emotional distress for a considerable period of time.
The more useful question may be:
What does it cost me to keep functioning this way?
Understanding our personal energy economy gives us another way of thinking about wellbeing.
Not:
How much can I make myself do?
But:
How can I live, work and relate in ways that I can sustain?
That shift can create space for something important — responding to ourselves with greater understanding rather than continually asking ourselves to override what we are experiencing.
And perhaps that is one of the most valuable aspects of paying attention to energy exchange.
It helps us notice not only where our energy goes, but also how we are showing up for ourselves along the way.
A reflection to take with you
For the next few days, notice three things:
What takes from me?
What gives back to me?
What am I doing that costs more energy than anyone else can see?
You don’t need to change anything immediately.
Sometimes noticing is the beginning of understanding.
