Autistic Inertia: Why Everyday Tasks Feel Overwhelming (Autism & ADHD) | CADS

“I know it only takes five minutes.”

“I don't understand why I can't just do it.”

“Everyone else seems to manage these things without thinking.”

These are comments we hear every day from both autistic people and people with ADHD. Tasks that appear simple from the outside—getting dressed, making a phone call, replying to an email, having a shower or putting the washing away—can feel surprisingly difficult to begin or complete.

This isn't laziness, a lack of motivation or simply “not trying hard enough.” Instead, it often reflects differences in how the brain processes information, plans actions, manages attention and copes with change.

Everyday tasks are rarely just one task

One reason daily activities can feel overwhelming is that our brains tend to think of them as single, straightforward jobs.

Take making a cup of tea.

To most people, it sounds like one task.

For someone who is autistic or has ADHD, the brain may automatically recognise all of the smaller steps involved:

• Decide to make a drink

• Stop what you're currently doing

• Stand up

• Walk to the kitchen

• Fill the kettle

• Wait for it to boil

• Find a mug

• Choose a tea bag

• Remember where the milk is

• Make the drink

• Wash the spoon

• Return to what you were doing

Each individual step requires attention, planning, working memory and a shift in focus. When your brain is already working hard to process the world, even simple tasks can begin to feel surprisingly exhausting.

Executive functioning: the brain's management system

Executive functioning is often described as the brain's management system. These skills help us to:

• Plan what needs to be done

• Get started

• Organise information

• Remember the next step

• Prioritise

• Manage time

• Switch between activities

• Finish what we've started

Both autism and ADHD are commonly associated with differences in executive functioning.

This means that the challenge isn't usually knowing what needs to be done—it's turning that knowledge into action.

Many people describe it as feeling as though their brain and body aren't communicating.

The invisible effort of transitions

One of the biggest challenges is transitioning between activities:

• Moving from relaxing to working

• From watching television to emptying the dishwasher

• From being warm in bed to getting into the shower

• From working at your desk to cooking dinner

Every transition requires the brain to stop one activity, disengage from it, prepare for something different and then initiate a new sequence of actions.

For autistic people, transitions can feel unsettling because they involve unpredictability and a change in routine.

For people with ADHD, transitions can be difficult because attention becomes “stuck” on the current activity or because getting started requires a level of mental energy that isn't always available.

This is why you might spend an hour thinking about doing something that only takes ten minutes.

Decision fatigue

Many everyday tasks involve far more decisions than we realise:

• What shall I wear?

• What should I eat?

• Should I do the washing first or answer that email?

• Do I need to leave now or in ten minutes?

Each decision uses mental energy.

By the time you've made dozens—or even hundreds—of small decisions throughout the day, your brain may simply run out of capacity.

This is one reason why routines can be so helpful. They reduce the number of decisions your brain has to make.

Sensory demands add another layer

Many daily activities involve sensory experiences that other people barely notice.

A shower may involve:

• Bright lights

• Cold bathroom tiles

• Changing temperature

• The sound of running water

• Different textures

• Strong-smelling toiletries

• Drying your skin afterwards

Getting dressed involves labels, seams, waistbands and fabric textures.

Cooking may involve smells, heat, noise and multiple things happening at once.

When your nervous system is already processing sensory information more intensely, everyday activities require significantly more effort.

Anxiety makes everything feel bigger

When someone is already anxious, even small jobs can feel enormous. You may worry about:

• Forgetting something

• Making a mistake

• Choosing the wrong option

• Not having enough time

• Being interrupted

• What comes next

The brain begins treating ordinary tasks as though they are much bigger than they really are.

The result? Avoidance.

Unfortunately, avoidance usually increases anxiety because the unfinished task continues occupying mental space.

Why can I think about it but not do it?

This is one of the most frustrating experiences for many autistic people and those with ADHD.

You know the task needs doing.

You want to do it.

You may even feel guilty about not doing it.

Yet your body simply doesn't seem to respond.

This experience is sometimes linked to executive functioning differences and, for many autistic people, autistic inertia—a difficulty initiating, stopping or changing actions despite having the intention to do so.

The barrier is not motivation. It's accessing the mental processes needed to begin.

Small changes can make a big difference

Rather than expecting yourself or your child to “just get on with it”, it can help to reduce the demands of the task itself. Helpful strategies include:

• Breaking tasks into very small, achievable steps

• Using visual checklists

• Reducing unnecessary decisions through routines

• Preparing items in advance

• Using timers or body doubling (working alongside someone else)

• Allowing extra transition time

• Reducing sensory discomfort where possible

• Celebrating progress rather than perfection

Often, making a task easier is far more effective than trying harder.

A different way of understanding

If everyday tasks feel overwhelming, it's important to remember that this doesn't reflect your intelligence, ability or willingness.

Many autistic people and people with ADHD work incredibly hard simply to complete tasks that others barely notice.

When we understand the hidden demands behind everyday life, we can replace judgement with compassion and frustration with practical support.

Sometimes the biggest challenge isn't the task itself—it's everything the brain has to do before the task can even begin.

And recognising that difference can be life changing.
