Feel Good Science
A wee bit about spoon theory
You might have come across spoon theory - an idea that started in the chronic illness community as a way of explaining why ordinary tasks can be exhausting when everyone else assumes they're easy. The idea is you start each day with a certain number of spoons. Tasks cost spoons. Once they're gone, they're gone until you properly rest and refill.
It's been picked up widely in mental health and neurodivergent spaces too, because most of us recognise the feeling even if we've never had the words for it.
Here's the part that's less talked about: your D.O.S.E. systems don't just refill your spoons afterwards. They change how many spoons a task costs you in the first place. When dopamine is flat, a one-spoon task can feel like it costs ten. When your systems are running well, the same task costs much less.
So this isn't really about resting more - though rest matters. It's about noticing what changes the price tag.
The four systems:
Dopamine - Motivation & Drive
Your get-up-and-go system. It responds more to progress than to completion, which means small wins genuinely count. When dopamine is low, starting things feels hard, finishing feels hollow, and procrastination creeps in. It's not laziness. It's a system running low.
Serotonin - Calm & Mood
Your quiet, steady okay feeling. Serotonin gives you a baseline sense of wellbeing - not euphoria, just groundedness. Daylight supports it. So does movement, and noticing what you're quietly doing well. When it dips, irritability and overwhelm often fill the gap.
Oxytocin - Connection & Trust
The feeling of being safe with people. Oxytocin is released through genuine connection - real conversation, physical touch, being properly seen by someone. We often underestimate how much we need it, especially when life gets busy or isolated.
Endorphins - Relief & Ease
Whatever loosens what's wound tight. Movement, laughter, crying, singing - your body isn't fussy. Endorphins are about physical and emotional release, and when they're low, things tend to feel tense, tight, and harder to shift.

A gentle guide to your energy and feel-good systems
Most of us have heard of the “feel good chemicals”. Fewer of us know that they are four interconnected systems - dopamine, oxytocin, serotonin, and endorphins, collectively known as D.O.S.E. - and that they have far more influence over how we feel day to day than we tend to give them credit for.
These aren't just mood chemicals. They regulate energy, motivation, stress, connection, and how much everyday tasks cost us. When one system is running low, everything feels harder - not because you're failing, but because the system is depleted. When they're reasonably balanced, the same tasks genuinely feel lighter.
That's not a metaphor. That's physiology.
