Experts say digital multitasking harms brain, nervous system
The Washington Post reports that performing several tasks at once can harm the functioning of the brain and the nervous system. An expert quoted by the paper said it creates only an "illusion of productivity" and that "our brains simply aren't wired for it", citing constant "context switching" without breaks. Digital multitasking, using more than one screen at a time, is the most common form. Suggested remedies include meditation, single-tasking, silencing notifications and limiting screen time. The Times reported that about 1,000 teenagers paid to sleep at least seven hours on weeknights improved academically.

Analysts’ view opinion
This reads as a health story, but its real significance is in policy design. Every remedy cited — meditation, single-tasking, silencing notifications, cutting screen time — places the burden squarely on the individual, while nobody is held responsible for the design choices that make screens compelling and habit-forming. By contrast, the sleep finding points to something a policymaker can actually work with: a structured, incentivised intervention that coincided with better academic performance.
- Framing the problem as a personal habit makes self-discipline the cure; framing it as product design shifts responsibility to platforms — and this story leans toward the first framing.
- Experience with earlier public-health policy on tobacco, food labelling or helmet rules suggests awareness messaging alone moves behaviour only so far.
- The sleep study is the policy-relevant part because it was an incentivised intervention, the kind of lever that connects to school timings, exam calendars and homework load.
- The core implementation problem is that workplaces and schools themselves often mandate constant notifications and multiple screens, so individuals cannot simply choose to single-task.
- The story notes not all multitasking is harmful, so any rule or guidance should target digital, multi-screen use rather than sweeping restrictions.
What to watch — Watch whether school systems or employers convert this into institutional rules on screens, notifications and sleep-friendly scheduling, or whether it stays purely personal advice.
This is a press review, not a policy document: it cites no government measure, regulation or proposal, and the sleep study's design, size details and causal claims are not established here.

Context
A France 24 press review (Tuesday, September 22) highlights a Washington Post report headlined "Toxic multitasking is breaking your brain", which argues that doing several things at once — especially across screens — damages brain and nervous-system functioning rather than raising output. The piece describes multitasking as the "new normal" in an always plugged-in world, and as potentially addictive when screens are involved. It also cites a study reported by The Times in which about 1,000 teenagers were paid to sleep at least seven hours on weeknights and saw their academic performance improve. The same press review covered unrelated items on Russian mobilisation rumours, an NYT interview with South Korea's President Lee Jae-myung, and Alaska's Fat Bear Week.
Key facts
- The Washington Post article is headlined "Toxic multitasking is breaking your brain" and explains how to "take control".
- An expert quoted by the Post says multitasking gives only an "illusion of productivity" and that "our brains simply aren't wired for it".
- The harm is attributed to constant "context switching" without a break, which the source says is detrimental to the brain and nervous system.
- Examples of everyday multitasking cited: scrolling while watching TV, reading emails while in a meeting.
- Experts say not all multitasking is bad, but digital multitasking — using more than one screen at a time — is the most common form and ironically weakens the ability to multitask where it could be beneficial.
- Suggested remedies: meditation, practising single-tasking, and "design your environment for success" — silencing notifications and limiting screen time.
- The Times reported a study in which some 1,000 teenagers were paid to sleep at least seven hours on weeknights; they were better rested for school and their academic performance increased.
- The press review carrying these reports was broadcast on Tuesday, September 22; France 24 airs it at 7:20am and 9:20am Paris time, Monday to Friday.
Timeline
- Tuesday, September 22France 24 press review features The Washington Post report on toxic multitasking and The Times report on the teenage sleep study.
Who has a stake
- Screen users / working professionals — Risk of impaired brain and nervous-system functioning from constant context switching, plus an "illusion of productivity" at work.
- Teenagers and students — Study of about 1,000 teenagers suggests at least seven hours of weeknight sleep improves rest and academic performance.
- Experts quoted by The Washington Post — Advancing the argument that brains "aren't wired" for multitasking and recommending single-tasking, meditation and notification control.
- The Washington Post and The Times — Media outlets reporting the science on multitasking harms and the sleep-and-academics study.
- Employers and schools — Environments built around always-on screens and notifications shape whether multitasking habits can be broken.
Why it matters
Digital multitasking is described as the new normal and potentially addictive, yet the source says it harms brain and nervous-system functioning while only creating an illusion of getting more done. For students and workers alike, the reported fixes — single-tasking, silencing notifications, limiting screen time and adequate sleep — are low-cost behavioural changes with measurable benefits, as the teenage sleep study suggests.
UPSC angle
Prelims pointers
- "Toxic multitasking is breaking your brain" — Washington Post report cited in France 24's press review of September 22.
- Digital multitasking = using more than one screen at a time; described as the most common form of multitasking.
- "Context switching" without breaks is the mechanism the source blames for harm to the brain and nervous system.
- Remedies listed: meditation, single-tasking, silencing notifications, limiting screen time.
- The Times: about 1,000 teenagers paid to sleep at least seven hours on weeknights showed improved academic performance.
Mains framing
The story frames digital multitasking as a public-health and productivity paradox: an always plugged-in environment normalises scrolling while watching TV or reading email in meetings, yet experts quoted by The Washington Post argue that the brain is not wired for it and that constant "context switching" without breaks harms the brain and the nervous system, yielding only an "illusion of productivity". The causes lie in design and habit — screen-driven multitasking is described as addictive — and the implication is self-defeating: the form of multitasking people do most reduces their capacity to multitask in situations where it could be beneficial. The remedies offered are individual and environmental rather than regulatory: meditation, deliberate single-tasking, silencing notifications and limiting screen time, alongside sleep, with The Times citing roughly 1,000 teenagers paid to sleep at least seven hours on weeknights who were better rested and performed better academically. A way forward grounded in the source would combine awareness of the cognitive costs with environment design at home, school and workplace; the source does not state any policy measures.
Key terms
- Toxic multitasking

- Single-tasking
- Deliberately doing one task at a time; recommended by the Post as a way to break the multitasking habit.
- "Design your environment for success"
- Advice from the Post to cut triggers — silencing notifications, limiting screen time and similar steps.
Practice questions
- Examine the claim that digital multitasking creates only an "illusion of productivity". What behavioural remedies does the evidence cited support?
- Discuss the links between sleep duration, cognitive performance and academic outcomes, with reference to the study of about 1,000 teenagers reported by The Times.
- "Screen-driven context switching is an emerging public-health concern." Comment, suggesting measures for schools and workplaces.
