TL;DR.<\/strong> Attention is usually treated as a matter of discipline. A large body of research says it is also a matter of settings: the light, sound, temperature, air, objects and screens within two metres of you set the defaults your brain works against. The defaults are measurable. Office workers with windows slept 46 minutes more per night during the workweek than windowless colleagues (Boubekri and colleagues, 2014). Raising open-plan noise from 39 to 51 decibels reduced word memory and raised fatigue (Jahncke and colleagues, 2011), and performance on verbal tasks begins to fall once irrelevant speech becomes even slightly intelligible, at a speech transmission index of 0.21 (Haapakangas and colleagues, 2020). Office task performance peaks at around 22 degrees Celsius and is 8.9 percent lower at 30 degrees (Seppanen, Fisk and Lei, 2006). In a blinded exposure study, cognitive scores were 61 percent higher on a low-pollutant day and 101 percent higher on days with doubled ventilation than in a conventional office (Allen and colleagues, 2016). Across 22 studies, the mere presence of a smartphone costs a small but real amount of cognitive capacity, g = -0.14 overall and -0.23 for memory (Bottger, Poschik and Zierer, 2023). A notification you never open still disrupts an attention task about as much as answering it would (Stothart, Mitchum and Yehnert, 2015). None of these effects is large on its own, but all of them are cheap to change, and most people have never changed any of them. The CEO move is to treat your workspace as infrastructure with specifications. The student move is to run the 20-item checklist below, change the three cheapest failures, and measure for two weeks.<\/p>\n

This article is part of the attention hygiene series that starts with the notification audit<\/a>. That piece covers the signals that reach you. This one covers the room they reach you in, physical and digital, and what the evidence says each setting is worth.<\/p>\n
