Researchers have revealed that multi-tasking can actually result in reduced memory, poorer decision-making and long-term brain decline with one doctor declaring ‘multi-tasking is a myth’

Multi-tasking is making people more stupid because our silly brains cannot cope with juggling lots of different activities at once, according to scientists.
Traditionally seen as a skill that helps us handle the pressures of our busy work and family lives, researchers found the habit can actually result in reduced memory, poorer decision-making and long-term brain decline. Neuroscientist Dr James Turner put it: “Multi-tasking is a myth. The brain isn’t designed to handle more than one task at a time.
“Each time you switch between tasks, it takes a moment for your brain to reorient and refocus, which slows down cognitive processing and increases mental fatigue.” It comes as a ‘mystery illness’ reportedly causing a surge in hospital admissions in China has seen a wave of individuals grappling with respiratory infections.

Dr Turner added: “The brain is like a computer – when it’s overwhelmed with multiple tasks, its performance is compromised.
“People think they’re being more productive, but the opposite is true. Multi-tasking actually makes people less efficient, and over time, it contributes to cognitive decline.”
But with a switch to focusing on one thing at a time, Dr Turner said people could reverse the effects of “chronic multi-tasking”.
The brain expert, commenting on the findings of a new study by data analysis firm Cardplayer Lifestyle, said: “By practicing single-tasking, people can actually improve their focus, memory and productivity.
“It’s a simple yet effective strategy to keep your brain healthy and sharp.”

The report found nine in 10 UK adults regularly multi-tasked. And two in five who split their attention between multiple tasks performed worse on memory and problem-solving challenges, compared to single-taskers.
The study said: “Multi-tasking, which many people believe is a sign of efficiency, is actually putting a strain on your brain.
“Research from top neuroscientists reveals that constantly switching between tasks – like answering emails while watching TV, juggling multiple apps on your phone, or even doing work while running errands – overloads your brain’s processing power.
“This results in reduced memory recall, slower decision-making and even long-term cognitive decline.”
