Different kinds of tired: social, sensory, decision

There are three everyday kinds of tired: social, sensory and decision. Below is what can come before each, and ideas people use for each.

What are the different kinds of tired?

"Social tired", "sensory tired" and "decision tired" are everyday names. They are not medical ones. They help you notice what came before the tiredness, and that can point to the rest that fits.

• Social tired can follow talking, groups, hosting or calls.
• Sensory tired can follow noise, bright light, crowds or strong smells.
• Decision tired can follow many small choices, or tasks with no clear start or end.

For social tired, autistic adults describe time alone ^[9]. For sensory tired, the National Autistic Society lists lower input, a retreat space, ear defenders and sunglasses ^[8]. For decision tired, ADDitude lists routines and fewer options ^[10].

What helps when you are tired after being with people?

Time alone is something autistic adults describe. In interviews with 16 autistic adults in the United Kingdom, people said they pulled back from social and sensory overwhelm, used time alone to settle, and then felt ready to reconnect. The researchers concluded that a balance of social time and time alone matters, and that keeping a space for it supports recovery ^[9]. There is more in recovering after time with people.

Some people tell the people around them that time alone afterwards is how they recover. Before the event, you could say:

"I'd like to come, and I may head off early."

Once you are home, or in the car park:

"I'm going to be quiet for a while. It's how I recover."

And when someone asks if you are all right:

"I enjoyed that. I need some time alone now."

Studies of adults in general show a pattern with timing. In a 2017 study, 48 people answered questions five times a day for 12 days. Being sociable went with feeling more cheerful in the moment, and with more tiredness about 3 hours later. This held for people with different personalities ^[1]. In a 2020 study of 74 students in Helsinki, being sociable in the previous hour was linked to feeling tired 2 to 3 hours later ^[2].

What helps when the noise and light were too much?

Lowering input is something people describe. In an online survey of 78 self-identified autistic adults, tiredness after overload was widely described. Many said they needed to be alone and away from input afterwards. People described rest as how they recovered, and said that lowering sensory input made the rest work ^[5].

The National Autistic Society lists ideas for this ^[8]. The page mentions keeping lights, sound and talking low while someone settles. A quiet room or a spot outside can be a place to retreat to. Ear defenders or noise cancelling headphones help some people, and so do sunglasses or tinted glasses. The page also says using ear defenders a lot may increase sensitivity over time.

The same page suggests a sensory diary that records triggers, times of high or low energy and what helped. It also notes that being tired can make overload more likely, so each can make the other more likely ^[8]. More on this is in sensory overload in adults.

What helps when you have made too many decisions?

Fewer small choices is the main idea. ADDitude, a magazine for people with ADHD, lists several ways to get there ^[10].

One is routines and habits. A set number of work outfits, meals planned by day, two or three weekly menus in rotation, a master grocery list.

For big choices, some people write out pros and cons, then look again the next morning if there is no rush.

For autistic adults, a questionnaire study of 38 autistic adults and 40 adults without autism found that the autistic adults reported more problems with decisions, and were more likely to say they avoided them ^[6]. ADDitude's ideas are aimed at cutting the number of choices, and some people find they take load off.

You may see this called "decision fatigue". The ideas above come from what people describe.

Is tiredness common for autistic adults or adults with ADHD?

Some people in both groups report it, in studies of each group on its own.

On one questionnaire, 72.8% of 290 autistic young adults aged 18 to 26 in the United States reported tiredness in the past three months. It was the most common of the 14 body-related things they were asked about ^[3]. In a 2017 study of 243 adults with ADHD who were using clinic services, 62% met the authors' criteria for fatigue. The ADHD group reported more tiredness than a comparison group of 211 adults ^[4].

If you recognise this, some others describe it too. You do not need a label to start trying one of the ideas above.

When can a clinician look at long lasting tiredness?

The NHS page on tiredness and fatigue says a GP (family doctor) can be seen when tiredness goes on for a few weeks without a clear reason, when it affects daily life, or when it comes with other changes such as weight loss or changes in mood ^[7].

Tiredness has many possible causes, and a clinician can look at them.

About this article

• The ideas come from the studies cited, from guidance pages (the National Autistic Society, ADDitude, the NHS), and from people's own accounts. The three kinds of tired, the examples under each and the three sentences you can borrow are Mindum's own wording and grouping. You can change them to sound like you.
• The studies on tiredness and sensory overload are with autistic adults, the ADHD study is with adults using clinic services, and the social timing studies are with adults in general. Several were read as abstracts, as marked in Sources.
• If tiredness is lasting, new or comes with other changes, a clinician can look at it.
